Script and Expression problem

Maya
1

im pretty new to MEL so please be patient with my query. So here it goes -

when i execute this line -

joint1.rotateZ = sin ( time )*10 ;

with the script editor it givs me error saying " invalid use of maya object time " but works perfect when i put the same line in the expression editor.

Why is this?

I also could not find " time " command in the maya mel refrence ? why is that ?

1)
You can directly assign to an attribute, like "joint1.rotateZ = sin ( time )*10 ;" only inside an expression - but not in script editor. In script editor, u have to use "setAttr".

2)
Use "currentTime" command in place of "frame" (or "time") in script editor.

so, ur script shud b:

int $fram = currentTime -q;
setAttr "joint1.rotateZ" (sin($fram/(float)24)*10);

//Divide by 24 to calculate time if frames/sec = 24
