blink within a loop
I’ve googled it, looked at tutorials etc, still can’t get my head around it or get a tutorial to work…
I’ve got a precomp of an 8 frame walkcycle. On one of it’s layers I’ve got an ‘eye’ precomp consisting of two frames: eyes open and eyes closed.
I’ve got the walkcycle looping in my main comp, using timeRemap and this simple expression:
loopOut(type = “cycle”, numKeyframes = 0)Now I’d like to make the looping walkcycle precomp tell the eyes precomp (that is inside it) to blink where ever there is a layer marker on the walkcycle precomp – and to make use of the layer markers duration to hold the blink for the same duration.
anybody know the answer?
I’m thinking it’s quite simple, but coming from a Actionscript background I’m getting really stuck with Expressions…
I’d simply do this in Flash: walkcycle_mc.eyes_mc.gotoAndStop(2)
thanks,
Graham.

I would do this inside the eye precomp:
In the eye precomp, make two layers (EyeOpen and EyeClosed) last long enough (the duration of the walkcycle or main comp). And animate these two layer’s opacity property:
in one of the layer (e.g., EyeOpen):
// Find which two markers the current time is in between.
var markers = comp(“WalkCycle”).layer(“LayerWithMArker”).marker;
for (i = 1; i <= markers.numKeys + 1; ++i) { if (time < marker.key(i).time) { break; } } (i % 2 == 0) ? 100 : 0 in the other layer ("EyeClosed"), just use 100 - thisComp.layer("EyeOpen).opacity this makes sure when eyeopen is visible, eyeclosed is invisible, vice versa Xinlai Ni Software Engineer, Google Inc. -
I think your problem is going to be that the time inside the time-remapped pre-comp never gets beyond your 8-frame loop. You’d need your eyelid to be outside of that comp to be able to detect any markers in the main comp beyond the 8-frame loop.
