I have downgraders at my disposal. I still want it D:

A couple people can vouch for its sheer awesomeness though.

I made it in patch 1.16 so it doesn't really work in the new patch

Do you still have that/those map(s)? I want to see them.

I also had right click detection. For example, you could make it so that if you right clicked a barrack and you were next to it you would enter it like a building

This is just EUD selection? Why does it desync? I've done EUD selection to switch between a marine, ghost, and firebat in what appears to be the same thing you're doing. I also used hp detection so that if one of the units was damaged then the other two units hp were set to the same amount. Basically it was shared hp among three different units. I also had attack detection.

This could make a bitchin' spell-casting system for a single-player RPG.

Nice man, now, to find a way to implement this into a multi-player way to work this thing, ike have 2+ people have the system in the same game and it works, just saying, we have to find a way
