[MAYA MEL PYTHON] simple variable question

[gnn]

Hello,

I'm trying to replace by a string variable a part of a mel command...and use this inside of a python script...

thank a lot for helping me

 

string $SceneName = "100";
lookThroughModelPanel PL_" + $SceneName + "_CAM:Cam_Rig:camera_Model modelPanel4;

Is PL_ also supposed to be a string?  Seems like you just missed your quotation marks at the beginning and post string that surround the arguments.  Also...I'd recommend not hard baking these sorts of things in, but passing as an argument...

Aka:

lookThroughModelPanel ("PL_" + $SceneName + "_CAM:Cam_Rig:camera_Model") "modelPanel4";

Have a look at this guy's post about this and a good tip in the future is to google the function name since there's tons of posts online about these these days:

You should also look at a refresher of variables/string concatenation just so you can learn a little bit more about how to use them in MEL:

If this is being called from a Python script, you could also just make use of Python string formatting:

import maya.mel as mm

sceneName = '100'

panelName = 'PL_%s_CAM:Cam_Rig:camera_Model' % sceneName

cmd =  'lookThroughModelPanel %s' % panelName

mm.eval(cmd)

thank a lot for helping me

 

string $SceneName = "100";
lookThroughModelPanel PL_" + $SceneName + "_CAM:Cam_Rig:camera_Model modelPanel4;
