I'm not sure which method you're looking for, but if you just want to cycle through the colors, you could do something like this: holdTime = 2; // hold each color for 2 seconds a = effect("Color Control")("Color"); b = effect("Color Control 2")("Color"); c = effect("Color Control 3")("Color"); colors = [a,b,c]; idx = Math.floor(time/holdTime)%colors.length; colors[idx] but if you want to pick the colors randomly, it would be more like this: holdTime = 2; // hold each color for 2 seconds a = effect("Color Control")("Color"); b = effect("Color Control 2")("Color"); c = effect("Color Control 3")("Color"); colors = [a,b,c]; seed = Math.floor(time/holdTime); seedRandom(seed,true); idx = Math.floor(random(colors.length)); colors[idx]         ...

A scale expression like this should size the text to fit the circle: d = thisComp.layer("Shape Layer 1").content("Ellipse 1").content("Ellipse Path 1").size[0]; // circle diameter r = sourceRectAtTime(time,false); w = r.width; h = r.height; angle = Math.atan2(h,w); wNew = d*Math.cos(angle); // desired text width sf = wNew/w; //scale factor [sf,sf]*100 ...

It's a tricky geometry problem. If you were using a rectangle shape (with anchor point centered), you could use something like this: h = content("Rectangle 1").content("Rectangle Path 1").size[1]; angle = degreesToRadians(content("Rectangle 1").transform.skew); value + [-(h*Math.tan(angle))/2,0] but that doesn't work with an irregular shape. I tried using sourceRectAtTime() to get the height, but I wasn't able to make that work. I'm stumped, but maybe someone will figure it out.   ... View more

You have to make sure that all layers other than your target layer are deselected. I usually deselect all layers in the comp, then select the target layer, then apply the preset. ... View more

Like this maybe: freq = 3; amp = 200; hold = .5; t = Math.floor(time/hold)*hold; wiggle(freq,amp,1,.5,t) ... View more

This example will create a text layer and set it to normal caps: var myComp = app.project.activeItem; var myTextLayer = myComp.layers.addText("Text"); var mySourceText = myTextLayer.property("ADBE Text Properties").property("ADBE Text Document"); var myTextDoc = mySourceText.value; myTextDoc.fontCapsOption = FontCapsOption.FONT_NORMAL_CAPS; mySourceText.setValue(myTextDoc); ...

There are optional parameters you can supply to specify how many decimal places (fraction digits), so this would be like toFixed(0): s = effect("Slider Control")("Slider").value; s.toLocaleString("en-US",{minimumFractionDigits: 0,maximumFractionDigits: 0}) de  ... View more

If I'm interpreting what you're asking correctly, you would enable time remapping, move the CTI to 2 seconds and click Time Remap diamond to create a keyframe there, and then use a Time Remap expression like this: t = time%(key(3).time - key(2).time); key(2).time + t ... View more

My guess is that you have the expressions engine set to Legacy ExtendScript in your project settings. ... View more

If you have a shape layer with a path, you could try an expression like this for the path property: freq = 3; amp = 30; p = thisProperty; pts = p.points(); newPts = []; for (i = 0; i < pts.length; i++){ seedRandom(i,true); w = position.wiggle(freq,amp) - position; newPts.push([pts[i][0] + w[0],pts[i][1] + w[1]]); } p.createPath(newPts,p.inTangents(),p.outTangents(),p.isClosed()) ...

Wow, sorry. That was some bad typing on my part. Try this: amp = 10; freq = 1; tStart = thisComp.layer("excuse line").content("Trim Paths 1").start.key(2).time; t = Math.max(time - tStart,0); y = amp*Math.sin(t*freq*Math.PI*2); value + [0,y] ... View more
