currentTimer help

[ageezer]

Firstly, I'm very new to MEL scripting.  To cut to my question, I'm looking for a way to set currentTime (current frame + 1).  I researched, couldn't find, and I ask for help.

If you care to see why I ask for this, it's because I'm trying to write a script that will:

-set keyframe
-unhide selected object
-increase current frame by 1
-set keyframe
-hide selected object

So far as a prototype, I've come up with:

global proc tl_ratt()
{
string $selected[] = `ls -sl` ;
 
setAttr ($selected[0] +".visibility") 1;
 
} 
tl_ratt ;

(Keep in mind I didn't even write the code myself, I found someone elses and inserted the "setAttr ($selected[0] +".visibility") 1;" snippet)

currentTime (currentTime -q +1) ;

however, instead of actually moving to the next frame, you can use;

string $mySel[] = ls -sl ;
setKeyframe -v 1 -attribute "visibility" $mySel[0] ;
setKeyframe -v 0 -attribute "visibility" -t (currentTime -q+1) $mySel[0] ;

well, my main goal is to create a cross section of my model, and create an animated blueprints to build the model out of blocks.  so i have a model 140 segments on its' Y axis.  I have 1 frame per Y axis segment.  i just build an animated cross section built from the bottom up and instead of manually increasing the frame, i do so in the MEL script. 

anyways, thats amazing how simply you put it.... thank you much.
