Irrlicht module: unofficial preview 3

[ErosOlmi]

Hi all.

3rd unofficial preview Irrlicht module wrapper for thinBasic.

Due to file size, we will not attach new release to post.
Please download it from http://www.thinbasic.com/public/products/thinBasic/Scripts/Irrlicht/pv3/Irrlicht_pv3.zip
Size: 4.8Mb

Before using it, please delete all previous sample Irrlicht scripts and related files. We are considering to create a dedicated SetUp_IrrlichtModuleWrapper.exe file for future updates. We will see.

Anyhow, Unzip in thinBasic directory maintaining directory structure.
Then go under thinBasic\SampleScripts\Irrlicht\ and execute thinBasic script samples. If not working let us know.

Attention:

irrlicht.DLL MUST be located into thinBasic.EXE executable folder in order to work. We are thinking how to avoid this but for the moment that is the way


Some thinBasic_Irrlicht module info:

developer: Roberto
module is developed using MS C/C++
thinBasic module wrapper is under development using thinBasic SDK for MS C/C++
irrlicht.DLL is compressed using UPX 3.00w original is about 1.4Mb while the one we distribute is about 510Kb
due to under development status and dll size, we will not deliver this module with official thinBasic release but we will keep a parallel temp project.
Later, when quite stable, we will decide how to go on


Have fun and please let us know if all is working fine on your box.
If not working, please tell us your OS and hardware config.

Ciao
Eros

Ok, I've tried it and it works on my computer, as you can see. :)

I tried the Quake Map and it worked but in order to close the Window I had to use 'Alt + F4'.

Also after I finished using it, the Application was still running in the background and I had to use the TaskManager to close it.

I've tried other versions of Irrlicht in the past like the C++, C# and Java versions and I'd encountered these kind of problems before.

[ErosOlmi]

Thanks a lot matthew.

Yes, to close window you need to press ALT+F4, sorry I forgot to mention.
We also see in Irrlicht forum that there are some problems in releasing the engine when using Alt+F4. We are trying to investigate and force some internal shut down.

Roberto is aware of it but thanks a lot for reporting.

Eros

[RobertoBianchi]

Eros,

maybe you should update matthew's thincore.dll?

Roberto

[ErosOlmi]

matthew,

maybe Roberto is right. when we started developing Irrlicht wrapper we had some similar problems but we were able to fix it changing WHILE/WEND processing.
Can you please be sure to have current thinBasic preview version 1.3.0.1 updated 2007.05.06?

Thanks a lot.
Eros

[matthew]

I'd been using thinBASIC version 1.3.0.0. :P

I've just downloaded the new version and tried it.

After I shutdown the Application I checked the taskmanager and it wasn't running in the background. :)

[ErosOlmi]

Roberto's memory is still very good.

Perfect matthew. You was just loosing all those changes http://www.thinbasic.com/public/products/thinBasic/help/html/version_1_3_0_1.htm
:D

Attention. with preview version 1.3.0.1 one or two of NeHe examples had problems due to new way to parse parameters in some TBGL functions.
I've already fixed NeHe examples you posted in forum. You should fix your local examples. Mainly to fix the problem you need to add ( and ) to sorround function parameters when first parameter start with a numeric expression between ().

Ciao
Eros

[Petr Schreiber]

Roberto,

do you know it looks awesome ? ;)

Matthew - sorry for inconvinience with TBGL parenthesis issues, but it had to be changed to kick maximum speed possible from thinCore/TBGL.


Thanks a lot,
Petr

[kryton9]

Worked great guys. I ran it in directx 9.0c, opengl and software render and they all worked. Software render was interesting as it took some time to draw and it made the scene very grainy, so interesting to see. But directx and opengl ran smooth as a bell.

In case you missed it, arrow keys move you and mouse turns you. And as mention ALT+F4 to exit.

Thanks again Roberto!!

[Bagamut]

It working perfect for me (using OpenGL & DirectX 9). Maybe Frank Dodd's wrapper for FreeBasic can help develop irrlicht module: http://www.freebasic.net/forum/viewtopic.php?t=3584

[Michael Hartlef]

Hi Bagamut,

thanks for mentioning this. I forgot about it totally. As Roberto seem to have not interest in this anymore, I might have a look at this freebasic wrapper.

Cheers
Michael

[largo_winch]

anybody out there can help me to understand how to adept "irrlicht" wrapper for thinbasic? How has created "thinbasic_irrlicht.dll"? What tool I have to use? I want to create a dungeon with a monster in there with irrlicht/thinbasic :) petr, michael, eros, matthew, bagamut or some person of this forum site could help? you are welcome to give some infos or links or something else.
regards, largo

[ErosOlmi]

Hi largo,

sorry no-one replied to your request.
Irrlicht project was a Roberto Bianchi project, I just published it.

If I remember well, it was a wrapper of a C++ library. You need to have Microsoft C++ in order to go on with the project.

If someone is interested to go on, I can see if I'm in the position (I've to ask to Roberto about that) to publish source code of the wrapper.

I've tried to tranlsate "enum types" with thinbasic. See my example. The freebasic example I have desactivated and it's below thinbasic part. perhaps somebody can check the thinbasic code how to specify "types objects" with a number ( = 1) or better using equates and say what's correct?

Hi,

if you have FreeBASIC enum like this:


enum IRR_EEVENT_TYPE
IRR_EET_GUI_EVENT = 0
IRR_EET_MOUSE_INPUT_EVENT = 1
IRR_EET_KEY_INPUT_EVENT = 2
IRR_EET_JOYSTICK_INPUT_EVENT = 3
IRR_EET_LOG_TEXT_EVENT = 4
IRR_EET_USER_EVENT = 5
End enum
you can re-represent it in thinBASIC like:


Alias Long As IRR_EEVENT_TYPE
Begin Const 'IRR_EEVENT_TYPE
%IRR_EET_GUI_EVENT = 0
%IRR_EET_MOUSE_INPUT_EVENT = 1
%IRR_EET_KEY_INPUT_EVENT = 2
%IRR_EET_JOYSTICK_INPUT_EVENT = 3
%IRR_EET_LOG_TEXT_EVENT = 4
%IRR_EET_USER_EVENT = 5
End Const

...

Dim MyEvent As IRR_EEVENT_TYPE

MyEvent = %IRR_EET_USER_EVENT
or even simply as:


Alias Long As IRR_EEVENT_TYPE
Begin Const 'IRR_EEVENT_TYPE
%IRR_EET_GUI_EVENT = 0 ' -- Sets start of numbering
%IRR_EET_MOUSE_INPUT_EVENT ' -- This is automatically 1
%IRR_EET_KEY_INPUT_EVENT ' -- This is automatically 2...
%IRR_EET_JOYSTICK_INPUT_EVENT
%IRR_EET_LOG_TEXT_EVENT
%IRR_EET_USER_EVENT
End Const

...

Dim MyEvent As IRR_EEVENT_TYPE

MyEvent = %IRR_EET_USER_EVENT
Regarding original FreeBasic code, it would become something like:


Uses "console"

Begin Const 'MyEnum
%option1 = 1 ' -- Start from 1
%option2
%option3
End Const

Dim MyVar, MyVar2 As Long ' -- Integer would work as well, but LONGs are faster

MyVar = %option1
MyVar2 = %option2

Select Case MyVar
Case %option1
PrintL "Option 1"
Case %option2
PrintL "Option 2"
Case %option3
PrintL "Option 3"
End Select

Select Case MyVar2
Case %option1
PrintL "Option 1"
Case %option2
PrintL "Option 2"
Case %option3
PrintL "Option 3"
End Select

WaitKey

[largo_winch]

thank you petr for infos about "enum" translations help to thinbasic !

yoh! now I've done next step and crazy thing: I have translated the "irrlichtwrapper.bi" for thinbasic as include file (as well as I am able to do that after two hours!). see my zip folder. but I have to add something more. So I can imagine I have to connect the file to thincore? I must build a module engine?

[Petr Schreiber]

Hi!,

you are almost there!

Tip #1
Remove this code from the include file and examples:


Declare Function LoadLibrary Lib "KERNEL32.DLL" Alias "LoadLibraryA" (lpLibFileName As Asciiz) As Long

Dim hlib As DWord
Dim v As Long

hLib = LoadLibrary("IRRLICHT.DLL")
hLib = LoadLibrary("IRRLICHTWRAPPER.DLL")
Why? Because you can declare the DLL in the DECLAREs directly, see Tip #2 :p

Tip #2
Just specify the DLL directly in the declarations. That means for example this:


Declare Function IrrRunning Alias "IrrRunning" () As Integer
becomes this:


Declare Function IrrRunning LIB "IrrlichtWrapper.DLL" Alias "IrrRunning" () As Integer
Tip #3
Value initialization is not supported in declare statements, so this:


Declare Sub IrrStart Alias "IrrStart" ( _
ByVal device_type As IRR_DEVICE_TYPES, _
ByVal iwidth As Integer, _
ByVal iheight As Integer, _
ByVal bitsperpixel As Integer, _ 'unSigned
ByVal fullscreen As Integer, _
ByVal use_shadows As Integer, _
ByVal iCaptureMouse As Integer, _
ByVal vsync As Integer = IRR_OFF ) '
becomes (with Tip #2 applied as well):


Declare Sub IrrStart Lib "IrrlichtWrapper.dll" Alias "IrrStart" ( _
ByVal device_type As IRR_DEVICE_TYPES, _
ByVal iwidth As Integer, _
ByVal iheight As Integer, _
ByVal bitsperpixel As Integer, _ 'unSigned
ByVal fullscreen As Integer, _
ByVal use_shadows As Integer, _
ByVal iCaptureMouse As Integer, _
ByVal vsync As Integer) ' -- Removed initialization
Tip #4
Be precise, for example


you have IrrStart defined twice in the INC file, first as SUB (correct), second as function (wrong, delete it)
you need to be sure about data types, for example I have seen:


ByVal bitsperpixel As Integer, _ 'unSigned
.. but Integer is signed of course, so this is confusing
Beware! FreeBasic Integer is 32bit while ThinBASIC Integer is 16bit! So FreeBasic Integer should be Long or Int32 data type in ThinBASIC.
To see the details on FreeBASIC data types, look here: http://mateusz.viste.free.fr/dos/fb_types.pdf
(http://mateusz.viste.free.fr/dos/fb_types.pdf)To see the details on ThinBASIC data types, look here: http://www.thinbasic.com/public/products/thinBasic/help/html/numericvariables.htm

(http://www.thinbasic.com/public/products/thinBasic/help/html/numericvariables.htm)

I think you did good job, now just make the details fit and you can run Irrlicht tomorrow :)


Petr

[ErosOlmi]

Largo,

in thinBasic there is no need to use "LoadLib" to load a libraries in order to access sub or functions inside them: you just need to declare the needed sub/functions and all the rest will be done automagically. So change all your needed declares in order to use the LIB clause

The problem is that you need to declare your subs/functions using the LIB "libName" clause. See http://www.thinbasic.com/public/products/thinBasic/help/html/declare.htm

Other problems I've fixed in attached files:

in DECLARE statement you cannot indicate default values for optional parameters, just use OPTIONAL keyword for optional parameters
WSTRING is not supported. wstring is just a UNICODE (double byte) string. Use UCODE$ to convert from ascii to UNICODE string
IrrStart was defined more than once. I just commented some out and leave the first version I found in the include file. I do not know it it is ok or not

thanks to petr and eros! I have aim to manage this irrlicth monsterly stuff!

I see a little light at the end of the hole :) but there are some more questions.

eros, I didn't see your example until some seconds before my post here. I will check next hours.

I cannot load yet any irrlicht object (irr_mesh) gives still errors.

[ErosOlmi]

WSTRING are UNICODE strings while thinBasic strings are ascii strings.
Use UCODE$ to convert your string from ascii to UNICODE string when WSTRING is needed

[Petr Schreiber]

Your code:


'1) --------------------->
'#define IRR_OFF 0
%IRR_OFF = 0

'#define IRR_ON 1
%IRR_ON = 0

'2) --------------------->
'TYPE irr_node As LONG Ptr
Type irr_node
irr_node As Long Ptr

'Type irr_gui_object as Any Ptr
Type irr_gui_object
irr_gui_object As Any Ptr
End Type

'TYPE irr_mesh as LONG PTR
Type irr_mesh ' doesn't work for loading objects
irr_mesh As Long Ptr
End Type


can be converted as:


'1) --------------------->
'#define IRR_OFF 0
%IRR_OFF = 0

'#define IRR_ON 1
%IRR_ON = 1 ' ! -- You probably forgot this by accident :)

'2) --------------------->
'TYPE irr_node As LONG Ptr

'Type irr_gui_object as Any Ptr

I found some interesting game engine fully based on IrrLicht and Newton. Here the link to offical site (http://www.n3xt-d.org/index.html).

Overview:
N3xtD engine project is aimed specifically the 'alternative' languages (such as Basic, for example). He is compiling a number of known and proven tools like Irrlicht (v1.8.x) for graphics, Newton for the physical part, and some part of proprietary code, designed to improve overall.
This project is oriented primarily towards simplicity and ease of implementation, even if it is as complete as possible.

This engine has ports to PureBasic, FreeBasic, BlitzMax. This engine has more features then FreeBasic IrrLicht wrapper. Download page (http://www.n3xt-d.org/crbst_1.html).

[largo_winch]

here now I show four new irrlicht examples with thinbasic. feel free for testing. only the mouse control in dungeon-collision example doesn't work fully satisfied I will check if I can change that for next time.

it's good feeling to see the model and the rooms and the scene with living objects ;) (models)

feedback is important if these examples are working for you. all files in zip folder.

notation: only files with 3.8 mb files I can upload. it's possible to change that limitation?

thinbasic_irrlicht include file was updated.

eros please change that in thinbasic-code script example again, here I have some problems with code tags, sorry!:

Hi,

the examples are very nice, all of them ran without problem, except the irrlicht-collision-dungeon, where the camera movement on my PC was very slow (moved mouse by 40cm -> rotated by ~2 degrees).

This problem could be fixed by changing the rotation speed:


Camera = IrrAddFPSCamera(0,25,1,100.0,0.5,-1,0,irr_camera)


... but I am not sure if this fix is not just for my PC only. I am not sure what units the rotateSpeed uses.

A little later, testing on two laptops.

[largo_winch]

thanks bezumec, eros, petr for testing. I have found the problem some minutes before (I was too tired last night to check all features!), the camera speed rotation wasn't high enough. so you can use 50.0 or 100.0 for this. same thing petr has found (thanks!) for error checking.

these lines are important. the second value of IrrAddFpsCamera(0,50...) is important.


'-------------> Important -------------------------------------->
' next we add a first person perspective camera to the scene
Camera = IrrAddFPSCamera(0,50.0,1,100.0,0.5,-1,0,50) ' second number (50) gives speed rotation!
'-------------> Important -------------------------------------->


Internetsurfing: I am using at the moment linux and mozilla firefox, but I have some problems with code tags, don't know why.

Here a new fixed version of "dungeon-collision12a" example in zip file. Copy this file into first folder above. You can now move (and jump) through whole SCENE! That's really exciting ! :)

eros thanks for that:

Attachments limit for .ZIP file changed to 5Mb, hope it is enough

I will check if other irrlicht examples can work too for thinbasic. but I need time.

@bezumec: "N3xtD_FreeBasic.zip" can you check the link for me? or please give a link where I can download (right-click-mouse) to save download file? I have some problems here at the moment. Thanks for the link! (problem solved, downloaded file from another pc machine at work)

I will check to look for new quake or md2 models by internet googling.


Well, thnks to you for your efforts!!!
Really appreciated.

oh no, thanks to you for great thinbasic language ! you are welcome.

2) important notice: copy the content of new zip folder (monster-moving-fighting.zip) "data" folder and three *.tbasic examples (monster, woman, zombie) in main folder of my last post #25 (irrlicht-tb-largo3a-all) to run the examples.


bye, largo

Another open source library for FreeBASIC http://freebasic.net/forum/viewtopic.php?t=17406 based on irrlicht_c library from this project http://pir.sourceforge.net

hello. what's the sense of creation of a thinbasic module (here about irrlicht topic) or it's sometimes better to use an include file (translation) as I did with irrlicht wrapper? a) to be truly I don't know how to make module creation for irrlicht as there a native functions (dll, freebasic and specially irrlicht.dll ) they didn't exist for thinbasic yet. the kind of equate using (%) doesn't work for module creation, I am right? btw: I tried some steps in module directions (freebasic-> thinbasic) but didn't know exactly where to set a reliable function for thinbasic coming from freebasic that didn't exist native for freebasic or by using the "irrlichtwrapper.bi" would make errors if I am using these functions. do you understand me? ;) c) thanks for the link maxim, I will check next days. bye, largo hello. sorry for my english. i understand you badly. perhaps this link will help somehow http://www.thinbasic.com/community/showthread.php?11225

[largo_winch]

ok, same serious question again: where's better to create a module for thinbasic or what good reasons (benefits) there are to use an include file? perhaps eros or petr can talk about this topic or give advices. bye, largo

Hi Largo_Winch,

if include file works, the module would be redundant I guess. Some time ago, the DECLAREd functions in includes had slower execution than module based keywords, but I think the difference is no more so big.
That is the reason why for example OpenGL is provided via header and not module.

The general rule I follow is:

if it is just a wrapper of existing DLL -> make include
if it is something more, computionaly expensive and so on, then module is the way to go

i have added a rotating sun around a totem, with shadow enabled. i have used largo_winch example, and changed the floor by editing the texture inside *.pk3 since .pk3 is just a zip file. indeed i hate this room but can't use another one. i failed to load another using 3ds room model.
the dynamic shadows are useful in designing sundials which cast a shadow upon the position of the sun.
the game engines are too difficult to use, but as someone said about windows api: do not try to be smart with windows api just use it. this is the principle of operating a TV by only switching a button we don't need to know its internal circuits. and life are too short to learn everything.
i have added other md2 and obj files to experiment with
download the file from here:

(http://www.mediafire.com/?q28ewxy83w5qdwq)
P.S: the shadow are not correct visually, may be usefull in picasso art.

Hi Zak,

thanks for interesting demo!

On my PC, the totem did not get displayed at all, the console said:


Unknown data object in animation of .x file: Header


But when I tuned line 45 in the source to load some MD2 file directly, it worked okay.

another demo with irrlicht , show how to scale, position, rotate the objects. i have used the Largo wrapper.
also i must say that the maxim wrapper for python are excellent , it is available here http://sourceforge.net/projects/pir/
together with thinbasic, freebasic, and others codes wich used his irrlicht_c.dll more recent than what are posted here. i have tried all the python 26 examples and works okay by running test_python26.bat, and every time you press X or quit or alt+F4 you go to the next example. there are a youtube demo http://www.youtube.com/watch?v=pr7xl9PziRk
the above car example are not in the package. right click the video to copy its youtube address.
which show a Funny pure Python 3d vehicle. it is suitable for who want to study a million irrlicht examples tutorials wich are available in C++, and maxim wrapper are more irrlicht style.
now the problem here is that the cross model have no shadow, is it managed by the model designer to cast no shadow !!!, or a bug in irrlicht.
i have downloaded the model from here http://pauldahuach.com.ar/program_en.htm#Nehe31
and exported it by milkshape to obj file so to use it with this example. its structure are complex and not simply a 4 boxes.
i have also exported it to Ogre files (mesh, skeleton) so to use it in blitzmax flow3d http://flow3d.boxsnap.com/ Ogre library , and i have replace the robot by the cross model and i have disappointed that it show a shadow !!!!, may be ogre are more robust.
download my example (1.4 MB) from here:

Thanks, zak!
My last wrapper edition and examples accessible only from SVN here https://pir.svn.sourceforge.net/svnroot/pir or here https://pyirrlicht.googlecode.com/svn/trunk.
I planned make next release, but this require more time.

[zak]

Thank you maxim very much, i have downloaded most of the files, i run the test_python26.bat and see that there are improved files and a new files , i also enjoyed the great toy VehicleSceneNode and thanks for this.
the info when i run the batch is:
Irrlicht Engine version 1.8.0-alpha
Microsoft Windows XP Professional Service Pack 3
Using renderer: OpenGL 3.3.0
GeForce 210/PCI/SSE2: NVIDIA Corporation
OpenGL driver version is 1.2 or better.
GLSL version: 3.3
you may need to upload more media files , i have found the media folder in http://sourceforge.net/projects/irrlicht/files/Irrlicht SDK/1.3/irrlicht-1.3.zip/download works okay to texture many examples
regarding the cross shadow problem i have added the model cross.obj to the example specialFX.py and there is a shadow
http://s16.postimage.org/eh82lf2kl/special_FX.jpg


so i guess it is because you are using irrlicht v 1.8, while my thinbasic example above are using the wrapper which depends on an older version. in fact the developer of freebasic wrapper (http://www.frankdodd.screaming.net/IrrlichtWrapper/) stop its developing and the last post in the freebasic forum (http://www.freebasic.net/forum/viewtopic.php?f=14&t=3584&hilit=irrlicht) is 3 july 2011
the example specialFX works better for me when using the opengl, there are some problems with displaying the fire.
i attach the same your python example specialFX_cross and specialFX_dwarf with its media files http://www.mediafire.com/?dc7itudk4c5z15z . works great with the new irrlicht_c.dll except the fire which are not displayed when i use opengl and displayed erroneously when using directx3d9 , but the fire is displayed okay and realistic like this in the dev-cpp irrlicht 1.3
http://s8.postimage.org/sspn9tkj9/special_FX_fire.jpg
as displayed by the same example in irrlicht 1.3 using dev-cpp.
but all in all it is great

[maxim]

Yes, you right, 1.8 have strange effect with particle system.
Thank you for found this.
I made support for Irrlicht 1.7.3 and commit revision to SVN, also add new chess gui example (require chess.ttf).
For testing with irrlicht_c_173.dll reverse comment in pyirrlicht.py on lines 49 and 50 (c_module = ctypes.CDLL(...))

[zak]

now it works, the light and the fire as should be, thanks maxim, the picture below is the same whether i use driverType = OpenGL or = DIRECT3D9 , it seems v 1.73 are better and also works correctly with DIRECT3D9.

[maxim]

ok
1.8 version valid work with EDT_BURNINGSVIDEO

also see new 2d game bricka (a breakout clone), original version developed by Leonel Machava, this demonstrate Irrlicht collisions detection
bricka_i.py from SVN

http://youtu.be/G_so6tjPnRM

[zak]

using driverType = EDT_BURNINGSVIDEO works for me with v1.8 in the specialFX example there is the light and the fire but too slow. also works with bricka_j in python26.
i will install python 3.2.2 , but i remember i can't install opengl on 3.x contrary to v2.6. i will see.
thanks

Hi all.

3rd unofficial preview Irrlicht module wrapper for thinBasic.

Due to file size, we will not attach new release to post.
Please download it from http://www.thinbasic.com/public/products/thinBasic/Scripts/Irrlicht/pv3/Irrlicht_pv3.zip
Size: 4.8Mb

Before using it, please delete all previous sample Irrlicht scripts and related files. We are considering to create a dedicated SetUp_IrrlichtModuleWrapper.exe file for future updates. We will see.

Anyhow, Unzip in thinBasic directory maintaining directory structure.
Then go under thinBasic\SampleScripts\Irrlicht\ and execute thinBasic script samples. If not working let us know.

Attention:

irrlicht.DLL MUST be located into thinBasic.EXE executable folder in order to work. We are thinking how to avoid this but for the moment that is the way


Some thinBasic_Irrlicht module info:

developer: Roberto
module is developed using MS C/C++
thinBasic module wrapper is under development using thinBasic SDK for MS C/C++
irrlicht.DLL is compressed using UPX 3.00w original is about 1.4Mb while the one we distribute is about 510Kb
due to under development status and dll size, we will not deliver this module with official thinBasic release but we will keep a parallel temp project.
Later, when quite stable, we will decide how to go on


Have fun and please let us know if all is working fine on your box.
If not working, please tell us your OS and hardware config.

Ciao
Eros

I think memory resource is still more important than hard disk, if a dll or exe is compressed by UPX,the file size reduces,but it will cost extra memory to run.
