Expression coding - Dimentionnal Pb

[alexx]

do you want to set a keyframe on the blendshape at a certain time to be 1 and have it fade of in the next 4 frames?

you can get the current frame with that command:

int $myTime = `currentTime -q`;

or, as you're working with expressions, you can use the predefined variables "time" or "frame" - this is faster than using mel.
eg:

float $blend;
int $initFrame =10;
int $numFadeOutFrames= 4;

if ((frame >= $initFrame)&&(frame<($initFrame+$numFadeOutFrames)))
{
$blend = 1.0 - (frame-$initFrame)/ $numFadeOutFrames;
}

this is the point where i think that i should read ALL the lines in the manuals...

in expressions frame and time are predefined?
oh oh..
i really never read that line in the manuals.. damn.
that would have sped up some of my particle scripts a lot :(

Thank you artifish and alexx,

I think I'll use mel, cause I need few "$initFrame" choose by random on the timeline.

In my script I want add randombly a blendshape movment...

I'll work on...
