- 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;
