I'd like to play a scene in the Blender game engine (I don't mind if it uses python). Basically, I'd like to say: "Play (backward or not) from frame X until frame Y," or, if it's not possible, at least "Display frame X".
With the older versions, it seems that IPO actuator was used for that. However, now the IPO actuator does not exists anymore, and it's supposed to be replaced by the Action actuator. However, the only way I found to make Action work is to specify an action ID. So only one object can move by actuator.
Of course, I could create a new action actuator for each object, but it's just crazy to maintain if there are more than 2 objects, and I can't find a way to automate it in python.
Do you have any solution for this problem?
