How to use the custom light position evaluator:
|
||
|
|
* Init code will be executed each time the window size is changed
|
||
|
|
or when the effect loads
|
||
|
|
* Frame code is executed before rendering a new frame
|
||
|
|
* Beat code is executed when a beat is detected
|
||
|
|
|
||
|
|
Predefined variables:
|
||
|
|
x : Light x position, ranges from 0 (left) to 1 (right) (0.5 = center)
|
||
|
|
y : Light y position, ranges from 0 (top) to 1 (bottom) (0.5 = center)
|
||
|
|
isBeat : 1 if no beat, -1 if beat (weird, but old)
|
||
|
|
isLBeat: same as isBeat but persists according to 'shorter/longer' settings
|
||
|
|
(usable only with OnBeat checked)
|
||
|
|
bi: Bump intensity, ranges from 0 (flat) to 1 (max specified bump, default)
|
||
|
|
You may also use temporary variables accross code segments
|
||
|
|
|
||
|
|
Some examples:
|
||
|
|
Circular move
|
||
|
|
Init : t=0
|
||
|
|
Frame: x=0.5+cos(t)*0.3; y=0.5+sin(t)*0.3; t=t+0.1;
|
||
|
|
Nice motion:
|
||
|
|
Init : t=0;u=0
|
||
|
|
Frame: x=0.5+cos(t)*0.3; y=0.5+cos(u)*0.3; t=t+0.1; u=u+0.012;
