Is there an official pause behavior/plugin?

I looked at rex pause, doesn't really seem to do anything.

Is there a pause plugin, or am I just going to have to do a custom: if paused -dont do things, stop animations,

on unpause: play animations - do every tick events?

Also, how would I pause physics things? They kind of do their own thing, and aren't really on every tick actions.

Is there a problem with using "set time scale to 0"?

When I set timescale to 0 to pause, and then unpause by setting timescale to 1 things go crazy, things shoot off in directions chaotically.

ahh... since people can still interact with objects...

You could set a pause variable... then add a condition that it doesn't work unless that variable is set to 1... (which would be unpaused)

Place what should be paused in a group and toggle it with the set time scale.
