How to execute a MEL command step by step?

[trs_andre]

Hi everyone,

I'm currently developing a script in MEL which is getting kind of complex, and I'm having quite a hard time debugging it. There are some results through the code that are not right, so I have been manually running blocks of code one at a time.

I was wondering if there is some kind of feature in Maya/MEL that allows to make a "step-by-step" or "line-by-line" run, with the possibility of including breakpoints in the code.

Please let me know if there is this feature, it would help a lot!

Thanks in advance!

Thanks for posting!

I don't believe we have a built in way to do this with MEL. Check out this guide about Python: Tips and tricks for scripters new to Python

Hi @faline.custodio.da.silva!

Thank you for your answer, and apologies for the late reply!

I see... It seems I'll have to get along with Python as well then!

You can use Visual Studio Code and an Extension called MayaPort or SendToMaya. Then you can debug your python code in Visual Studio Code, when Maya is running your code.

Thank you for your advice!

I'll try this method as well 😉
