Re: Setting range for Slider Control

Dan Ebberts · ‎Sep 08, 2010

As far as I know, there's no way to do that with a script. Dan

Dan Ebberts · ‎Sep 07, 2010

To set an expression: myLayer.property("Position").expression = "wiggle(5,10)"; To retrieve an expression var myExpr = myLayer.property("Position").expression; Dan

Dan Ebberts · ‎Sep 06, 2010

This might be what you're looking for: L = comp("configuration").layer("EDIT-TOP-TEXT-PANEL1"); n = 0; if (L.marker.numKeys > 0){ n = L.marker.nearestKey(time).index; if (L.marker.key(n).time > time) n-- } (n > 0) ? L.marker.key(n).comment : "" It should display the comment of the most-recent previous marker (or nothing, if there isn't one) Dan

Use seedRandom(seed,true) to generate the same sequence of random numbers on each frame. This should get you headed in the right direction: seedRandom(index,true); minStart = 0; maxStart = 5; myStart = random(minStart,maxStart); amt = linear(time, myStart, myStart+10, 0, -2000); value + toWorldVec([0,0,1])*amt Dan

Dan Ebberts · ‎Aug 30, 2010

[0,0,1] is vector pointing in same direction as the local z axis. toWorldVec() converts it to a vector in world space. "value" represents the pre-expression (i.e. keyframed or static) value of the property holding the expression (you can't alter it with the expression, you just reference it). Dan

Dan Ebberts · ‎Aug 30, 2010

Disconnect the layers from the null, and try this: amt=linear(time, index, index+20, 0, -2000); value + toWorldVec([0,0,1])*amt Dan

Dan Ebberts · ‎Aug 15, 2010

Try adding this to the end of your expression: [xposition,yposition] Dan

Dan Ebberts · ‎Aug 01, 2010

It's hard to picture how that would work, but you might play around with this, which keeps everything relative to the camera's POI: mult = -1; flare = thisComp.layer("flare"); center = thisComp.layer("Camera 1").transform.pointOfInterest; center + mult*(flare.toWorld(flare.anchorPoint) - center); Dan

Dan Ebberts · ‎Aug 01, 2010

Assuming your main flare element is a layer named "flare", an expression like this will position a layer on the line that goes through the flare and the center of the comp window. Adjust "mult" to set how far, relative to the distance between "flare" and the center. -1 puts it the same distance but on the other side. 0.5 would put it on the same side but half as far. You'll see... mult = -1; flare = thisComp.layer("flare"); compCenter = [thisComp.width,thisComp.height]/2; compCenter + mult*(flare.toComp(flare.anchorPoint) - compCenter); Dan

Dan Ebberts · ‎Jul 15, 2010

I think this is more what you're looking for: timeToStart = 2; t = time - timeToStart; if (t >= 0){ veloc = 35; amplitude = 30; decay = 1.0; y = amplitude*Math.cos(veloc*t)/Math.exp(decay*t); }else{ y = 0; } value + [0,y] Dan

Dan Ebberts · ‎Jul 11, 2010

How about this then: switchTime = 4; // switch at 4 seconds switchDur = .3; w = wiggle(.3,1000); if (time < switchTime) w else{ w2 = wiggle(2,30) - value; w + ease(time,switchTime,switchTime + switchDur,[0,0,0],w2) } Dan

Dan Ebberts · ‎Jul 11, 2010

Try this: switchTime = 4; // switch at 4 seconds if (time < switchTime) wiggle(.3,1000) else{ p1 = wiggle(.3,1000,1,.5,switchTime); p2 = wiggle(2,30,1,.5,switchTime); wiggle(2,30) - (p2-p1); } Dan

Dan Ebberts · ‎Jun 30, 2010

Try this: s = parent.transform.scale/100; [value[0]/s[0],value[1]/s[1]] Dan

Dan Ebberts · ‎Jun 29, 2010

You could just parent the smaller square to the larger and use an expression like this to counteract the scale of the parent: s = parent.transform.scale[0]/100; value/s Dan

Dan Ebberts · ‎Jun 09, 2010

No - sorry. Dan

Dan Ebberts · ‎May 23, 2010

Something like this: L1 = comp("Comp 1").layer("Layer X"); P1 = L1.toWorld(L1.anchorPoint); L2 = thisComp.layer("Comp 1"); L2.toWorld(P1) Dan

Dan Ebberts · ‎May 05, 2010

You can put all your variables in an object named after the script. See any of Jeff Almasol's scripts for an example: http://www.redefinery.com/ae/ Dan

Dan Ebberts · ‎May 03, 2010

In your project settings, do you have "Start numbering frames at:" set to one? That would do it. You could trysubtracting one, like this: framesToTime(parseInt(L.marker.key(n).comment,10)-1); Dan

Dan Ebberts · ‎May 03, 2010

Did you want the 4, 6, 8 markers to specify frames? The expression is currently treating those as seconds.Try changing this: parseInt(L.marker.key(n).comment,10); to this: framesToTime(parseInt(L.marker.key(n).comment,10)); Dan

Dan Ebberts · ‎May 02, 2010

Please specify your setup again (comp names, layer names, what's nested, what's time remapped, etc.) so I can make sure I set the expression up correctly. Dan

Dan Ebberts · ‎May 02, 2010

Try applying this to the time remap property of your TrmapLayer2: L = comp("MarkerComp1").layer("MarkerLayer1"); n = 0; if (L.marker.numKeys > 0){ n = L.marker.nearestKey(time).index; if (L.marker.key(n).time > time) n--; } if (n > 0){ parseInt(L.marker.key(n).comment,10); }else{ 0 } This should hold the time remapping at zero until a marker is reached on MarkerLayer1, then the time remap will be set to the value of the comment for that marker. If you have more than one marker, it will switch and hold each time it gets to the next marker. Dan

Dan Ebberts · ‎Apr 14, 2010

I don't think there's a built-in function for that, so you'll need to create one. Something like this should work: tMin = "0;00;01;00"; tMax = "0;00;01;07"; function convert(theString){ mySplit = theString.split(";"); t = thisComp.frameDuration * parseInt(mySplit[3],10) + parseInt(mySplit[2],10) + parseInt(mySplit[1],10)*60 + parseInt(mySplit[0],10)*3600; return t; } dist = 300; startPos = [301,240]; linear(time,convert(tMin),convert(tMax),startPos,startPos+[dist,0]) Dan

Dan Ebberts · ‎Apr 12, 2010

You didn't say how far you want the solids to move in 2 seconds so this example assumes 100 pixels to the right. Red position: dist = 100; startPos = [129,239]; linear(time,3,5,startPos,startPos+[dist,0]) Blue postion: dist = 100; startPos = [301,240]; linear(time,1,3,startPos,startPos+[dist,0]) Dan

Dan Ebberts · ‎Apr 01, 2010

Try this and see if it's close: L = thisComp.layer("leader"); delay = 1.5; timeToStart = 0; myDelay = (index - L.index)*delay; t = time - (timeToStart + myDelay); if (t > 0){ delta = L.transform.position.valueAtTime(t) - L.transform.position.valueAtTime(timeToStart); value + delta }else{ value } Dan

Dan Ebberts · ‎Mar 31, 2010

Maybe. It depends on what you mean by "automated edits". Dan

Dan Ebberts · ‎Mar 30, 2010

Marcus has done a lot of AE training and has written several books. I did the tech editing on this one and I think it's a great intro to expressions. Dan

Dan Ebberts · ‎Mar 24, 2010

I see a few issues here. if and else should not be capitalized. Compare your checkbox to 1, not true. The result of wiggle already includes the value of the property, so value + wiggle() probably won't give you what you expect. Dan

Dan Ebberts · ‎Mar 24, 2010

Assuming that the sliding layers are at the top of the layer stack and start out positioned at the center of the range, I'd try something like this: S = thisComp.layer("Null 1").effect("offset")("Slider"); m = Math.floor(index/2) * ((index%2) ? -1 : 1); value + [S*m,0] Dan

Dan Ebberts · ‎Mar 22, 2010

Expressions don't have access to font size, but you could use an expression to scale the text. Expressions also don't have access to the bounds of a text layer (although there is a hack to detect it using a sampleImage() loop. You could base the scale on the number of characters in the text, if that's close enough. Scripting does have access to everything you'd need to automate this - but you'd have to run the script whenever you changed the text. I'm guessing you could do it with a plug-in, but the learning curve for the SDK is pretty steep. Dan

Dan Ebberts · ‎Mar 20, 2010

Like this maybe? moveStart = 12; moveDuration = 1; seedRandom(18, true); z = linear(time,moveStart,moveStart+moveDuration, random (400,-400),0); [value[0],value[1],z] Dan
