One way:

x = clamp(value[0],0,200);
y = clamp(value[1],0,200);
[x,y]

Give this a try:

freq = 1.0; //oscillations per second
amplitude = 50;
decay = .7;

t = Math.max(time – inPoint, 0);
amplitude*Math.sin(freq*t*2*Math.PI)/Math.exp(decay*t)

I think we’re going to need more info on what you want the flower petals to do.

In your first expression, try replacing || with &&. You need an “and” operation there instead of an “or”.

In general, if you’re only worried about overlap in the x direction, you could do it like this:

x = thisComp.layer(“Null 5”).transform.position[0];
if (x > toWorld([0,0])[0] && x < toWorld([width,0])[0]) 0 else 100 Dan

Try this for the layer’s y rotation property:

delta = toWorld(anchorPoint) – thisComp.activeCamera.toWorld([0,0,0]);
radiansToDegrees(Math.atan2(delta[0],delta[2]))

Depending on what you’re after, it might be as simple as something like this:

posterizeTime(3);
wiggle(5,200)

Dan

[Dan Ebberts]

Have you tried wiggle? I’d set the opacity to 50% and then use something like this:

wiggle(0.5, 50)

I think try/catch is what you’re looking for. Example:

try{
C = thisComp.activeCamera;
}catch(err){
C = null;
}

Ah, AE 6.5. This should work:

length(pointOfInterest, toWorld([0,0,0]))

Dan

[Dan Ebberts]

If you have the POI where you want focus to be, this should work:

length(transform.pointOfInterest, toWorld([0,0,0]))
