Maya Maya MEL and Python Scripting 2

Question 1

What does `cmds.setAttr('pSphere1.translateX', 5)` do in Maya Python?

Accepted Answer

Sets the X translation of pSphere1 to 5 units

Answer

`cmds.setAttr` sets the value of a specified attribute on a node — here it moves pSphere1 five units along the X axis.

Question 2

What does the `select` command do in MEL?

Accepted Answer

Selects one or more objects or components in the scene

Answer

The `select` command in MEL programmatically selects scene objects or components, equivalent to clicking them in the viewport.

Question 3

What is a 'shelf button' in Maya scripting?

Accepted Answer

A button on the Maya shelf that executes a MEL or Python script when clicked

Answer

Shelf buttons store custom MEL or Python scripts and can be triggered with a single click, making repetitive tasks faster and more accessible.

Question 4

In Maya Python, what does `cmds.connectAttr('obj1.tx', 'obj2.tx')` do?

Accepted Answer

Creates a live connection so obj1's translateX drives obj2's translateX

Answer

`connectAttr` creates a live dependency graph connection between two attributes so any change to the source attribute immediately affects the destination.

Question 5

What does the `expression` node in Maya allow you to do?

Accepted Answer

Write mathematical formulas that drive attribute values procedurally

Answer

Expression nodes contain MEL-like mathematical formulas that are evaluated every frame to drive attribute values, enabling procedural animation and rigs.
