On 2.63 the bge.logic.KX_ACTIONACT_PLAY was playing by default with ‘continue’ disabled,so if you trigger it again before the action ends it goes to the first frame and starts over.
Blender 2.64 uses ‘continue’ by default and i cant toggle it so i can get the same result as 2.63.
Is this a bug? (2.64 is very buggy atm)
2.64 is a test build. That means you should report ALL bugs you find at the bug tracker (with details please). Otherwise they will not get fixed. (“is buggy” is not a report and not helpful at all)
And yes the described behavior looks like a bug.
