I'm working for some test on expression in order to create this 4 effects : - explosion of layers in 3D (actually working) - ascii version of some video based on one layer per character (actually working...slowly) - boid - layers (not yet) - "calligramme" based on video (not yet) example :...

New problem. I make my layer reference as 3D layer and move it fare away from camera (like -30000 in Z axis) because i'm using an trapcode horizon configuration. So i need to scale-it up (like 1500%) to have a good size. My solid are now 3D too, and i have changed the code with a toWorld instead of ...

I didn't know this variation about the pre and post expression value, with valueAtTime instruction.

Thanks Paul.

This is my script code. { var myProj = app.project; var myComp = myProj.activeItem; var mySelectedLayers = myComp.selectedLayers; app.beginUndoGroup("Function"); for (var i = 0; i < mySelectedLayers.length; i++) { var curLayer = mySelectedLayers[i]; var curTime = app.project.activeItem.tim...

My problem is basic. I have write à script who add a keyframe on position property at the current time. But i have an expression running on position property and it add only the originla value and not the expression value. Here is the code expression. I know that i can translate expression into key...

Thanks Dan and kobyg, it works.

But now the next part of my effects doesn't work.

Maybe it's impossible, but this problem is for a other topic.

Thanks for all.

thanks kobyg I think it's a part of the problem. I have try this in order to locate the origin of my bug. P1=[random(thisComp.width),random(thisComp.height)]; T1=thisComp.layer("Reference").sampleImage(P1); if (T1[3]==1) { P1; } else { [0,0] }; The solid stay in the corner of the comp many...

No change. I have tried this code on opacity and it works : P1=transform.position; T1=thisComp.layer("Reference").sampleImage(P1); if (T1[3]) { 100 } else { while (T2=0) { P2 = [random(thisComp.width),random(thisComp.height)]; T2 = thisComp.layer("Reference").sampleImage(P2); }; ...

I have often problems with using condition test in my expression. The code should work, but the logic of expression doesn't make what i think. This is the last example. I want that the object who i had expression on position, use random position value until it finds position value over a reference c...

The problem is parenting between the layer and not between the SureTargetNullObject and the camera. A basic example will be : a first text layer a second text layer parenting to the first a third text layer parenting to the second If i use the classic suretarget configuration the camera do something...

A link to understand of what we are talking : http://www.videocopilot.net/tutorials/presets_and_more/ This is the original code for the SureTarget 1.51 preser. ST = effect("SureTarget")("Curseur"); Min = Math.floor(ST); Max = Min+1; try{ L = effect("T-"+Min)("Calqu...

It works!

Script is so weird sometimes, you think that you have understand and new strange "words" appear.

Thanks Dan, i'm a huge fan of your work on motion script, everything is useful!

See you on the next problem.

I don't know if anybody here is using the Andrew Kramer SureTarget preset. He doesn't work with parenting layer, i have modified the expression for work with parent. It works perfectly with the position and for each rotation axis, but it doesn't work for simultaneous rotation in two or three axis. I...

The return of me! :P This time, it's for adding an expression to rotation in a 3D Layer. It works for zRotation, but i have a "read only" error for the xRotation and z Rotation, when i want to had an expression with my script. This is my code if (Premier) { myText.position = [360,288]; myT...

It works!!!

I have understand my mistake.

Thanks again!
