sometimes i want to use a method like timeToFrames or maybe the function linear. but when i work in my jsx file i think there is scoping problems.
here is my code it basically swings a picture in the middle back and forth
var myComp = app.project.activeItem;
if (myComp == null || !(activeItem instanceof CompItem)){
alert("Please establish a comp as the active item and run the script again");
} else {
var centerWidth = myComp.width/ 2;
var centerHeight = myComp.height / 2;
var plusWidth = 0;
var plusHeight = 0;
myComp.layer('Knut_IMG_8095.jpg').property("position").setValueAtKey(1, [centerWidth + plusWidth, centerHeight + plusHeight]);
for (var x = 1; x <= myComp.workAreaDuration; x++)
{
plusWidth = centerWidth*Math.sin(x*0.3);
myComp.layer('Knut_IMG_8095.jpg').property("position").setValueAtTime(x,
[centerWidth + plusWidth, centerHeight + plusHeight]);
}
So that is to give you idea im just learning this. i want to access a function say like "linear" how can i get access to something like linear?
Also is there code i can write that will be evaluated on a per After Effect "cycle" the way it happens when you write expression code say inside the position box? but externally? It seems that all a JSX can do is evaluate before the playback begins, so you won't have real-time access to real-time variable? Is this correct?
please help clarify!
