strobe expression
Second question for my danceclub rig…
If I wanted a light to act like a stroboscope, how would I do that with an expression?
Wiggle is too random, and I guess the value needs to be on or off, no interpolation.
Ideally I’d like to be able to set frequency and burst length.
Cheers,
Bar3nd

Hey Barend,
frequency=3; // times per second
burstlength=3; // in framest=time%(1/frequency);
t
change the lensflare expression to this, to factor in the Intensity of the light:
l=thisComp.layer("Light 1");
c=thisComp.activeCamera;
vec1=normalize(l.transform.position - c.position);
vec2=l.toWorld([0,0,-1]) - l.position;dotProduct = dot(vec2, vec1);
linear(dotProduct,-1,1,0,1) * value * l.intensity/100;

Hey Filip,
It seems like the ‘strobe’ expression is incomplete in the post, or am I missing something?
I just returns a value of 0.
Thanks,

Oops, there’s a lesser than character in there, that screws up the HTML formatting, check your email of the previous post for the correct version.
or this one should work online !but not in your email!
frequency=3; // times per second
burstlength=3; // in framest=time%(1/frequency);
t < framesToTime(burstlength) ? 100 : 0;
