endless scaling and moving on the z axis
by Jakob Roques on Jul 2, 2009 at 1:36:49 pm

Hello,

I hope you all understand my english.
sorry if this is allready been posted, but i have some problems with using expressions.
I want a object to scale from zero to endlessly during the composition. And I also want to move the object forward endlessly on the Z axis.

I used this expressions:

Position:
temp = time*-200;

[value[0], value[1], temp]

Scale:

temp = time*300;
[temp,temp,temp]

No problems til now. But, I need the other layers to follow 10 frames later and start at the same startposition and the same scale value (zero) as the first layer.

I hope you get my problem and I one of you can help me fix this.

Say the layer with your expressions is named "leader" and you have it at the bottom of the layer stack. You could apply a position expression like this to your follower layers:

delay = 10*thisComp.frameDuration;
thisComp.layer("leader").transform.position.valueAtTime(time - delay*index)

Each layer would follow the previous one by 10 frames. Is that what you're after?

For scale it would be:

delay = 10*thisComp.frameDuration;
thisComp.layer("leader").transform.scale.valueAtTime(time - delay*index)
