I have a character thats move forward by Motion Actuator but I need to make an accurate jump, so I made the jump movement by animation. In the "Jump" Action I've deleted the X and Y curves so only the Z curve will affect the character. I put it on a Action actuator and enabled the "Add" and the "Local" modes. but when my character jumps it cuts all the other movements, even the gravity, it don't affect the rotations thought, but I imagine if I put a Action whith rotation curves, will happen. I'm going to need make a lot of objects movements based in animation. Help?
I guess you're using an armature rig for your character. In Blender it is possible to play different animations at the same time, if they don't requier the same bone of your armature. So for example doing an action with the arms while walking shouldn't be a problem.
Therefore you need to move one of your animations to another animation layer.
I'm not sure how you've set up your character, but I hope it helps!
I solved, To make Game dinamic movements based in animation curves you must use "Delta Transforms", in "object's properties tab" to make the animation of the jump for example, In "Action Actuator" don't active the "add" and "local" buttons it won't interrupt other dynamics motions of the object.
