Expression to trigger movement with Camera distance
This question kind of ties in with Dan’s jack-in-the-box expression…..
I am wondering if it’s possible to trigger the popup with a certain distance to the camera. i.e.
as you get close to a layer in 3D space it folds up quickly. The popup motion, however, would have to be independant from the Camera in case you’re not getting close enough or fast enough to the layer to complete the popup…Any ideas? Dan?
Thanks

You can easily trigger motion by checking the range.
obj_pos=position;
cam_pos=thisComp.layer(“Camera”).position;distance=length(my_pos,cam_pos);
obj_scale=linear(distance,0,300,0,100);
out_scale=scale+obj_scale;
[out_scale,out_scale]
This would scale you object from 0 to 100 and figure in manually keyframed scale as soon as it is closer than 300 pixels to the camera. Play with the values and modify to your needs.
