... programmatically

Click on the Command Center to bring up its mode selection menu.

Is there away to actually switch the Command Center between Attack and Rally?

Clever idea, good execution, real QoL mod. Well done, this is just what I needed!
Extra props for posting the schematic, for non steamers!

Thanks! I'll take a look

For larger units, you can increase the approach radius, so that they will stay farther from the processor, or you can use the distance parking logic.

I like it a lot. The only problem I find is that units crowd over the switch and I can't get to it to turn it off. Is there any way of getting easier access to the switch if you have a lot of units on it?
