Description
Calculates a number between two numbers at a specific increment.

No |
First point. |
pEnd |
Number |
No |
Last point. |
Amount |
Number |
No |
Amount of interpolation |
Remarks
The Amount parameter is the amount to interpolate between [pStart and pEnd] where Amount=0.0 returns pStart, 0.1 is very near to pStart, 0.5 is half-way in between, etc.
Lerp function is convenient for creating motion along a straight path and for drawing dotted lines.
Lerp function differ from Lerp2 function only for the sequence of the parameters.
