Spring RTS Engine

This tag would tell a unit to not move forward at all when turning, optionally there could be a MinTurnSpeed and MaxTurnSpeed tag that define the lowest and highest speed a unit can move forwward at while turning.

The purpose would be to enable e.g. tanks to turn in place without moving forward while turning. This would also make limited arc units stay in their formation when aiming at something.

I think steering mode is supposed to do something similar, is that tag used by Spring?

+1 this would be really great.

Can be done through scripting but it's better this way.

Actually, doing this with scripting works great, and is very efficient, I've been using this quite a lot!

What do you mean with doing this with scripting, forcing a MAX_SPEED of 0 (or 1) when you detect rotation?

Yes. Make a backup of the original MAX_SPEED value, though, and then gradually reduce speed when the angle the unit has turned in time x exceeds a certain value, i.e. 45°/2 = MAX_SPEED*0.66, 45° = MAX_SPEED*0.33, 75° = 0.
