Controller for expressions
on Feb 10, 2010 at 9:31:22 pm

Hi all,
This is my first post in the Maya forum. (I usually frequent the After Effects, Apple Color and Final Cut Pro fora.)

I'm setting up a rigid body simulation, and want to more easily control some parameters of my rigid bodies and fields. Specifically, I have 11 objects and 11 radial fields, each paired one to one in Dynamics Relationships.

I know how to add expressions, but would like to somehow add a new "master variable" (or whatever the proper name is) for each of the parameters and then quickly add expressions from the object or field to the master variable, so that I can change the value of the specific parameter for all 11 objects or fields.

For example, object 1 has a parameter "rigidBody1.staticFriction" and object 2 has "rigidBody2.staticFriction".

Question 1: How do I define a new independent variable, such as MASTER.staticFriction (or MASTER_staticFriction if that's easier)?

Question 2: How/where do I most easily enter the following expression?


Thanks in advance!

I wouldn't use expressions but simply connect the attributes. This bit of MEL will connect the staticFricition attribute of a node called rigidBodyMaster to all other rigid bodies:

string $rigidBodies[] = `ls -typ rigidBody`;
$rigidBodies= stringArrayRemove({"rigidBodyMaster"}, $rigidBodies);
string $tmp;
for ($tmp in $rigidBodies) {
connectAttr "rigidBodyMaster.staticFriction" ($tmp + ".staticFriction" );
