Spring RTS Engine

Basicly I was wondering if these were even possible to do with the spring engine... TA shows that they certainly aren't needed to make a game fun and playable, but I'd still like to play with implimentations of them if they could be done. Can I impliment upgrade groupings or unit leveling with the current mod scripting or would more code need to be written into the TAS engine to make it possible?

You could kind of do it in TA by timing the delay between shots fired in a script (as a unit's veterancy rose in TA, its firerate decreased). You could use this to do stuff such as unjam other weapons, activate damage modifiers, etc. And for that matter, experience was very very noticable and vital to things like Big Berthas in OTA.

That said, I don't think much, if anything has been added script-side to the engine yet.
