Help me with max bones

#1 Not sure why or even how a custom bones rig would affect projectiles firing. Even if the nodes were pointed backwards the projectile would still fire towards the spot you are aiming at. It is possible that you really messed up the animation by not using a blend properly and as such when you play this animation, your weapon mount is shoved into the ground (or another object) and thus forces the porjectil to collide before it has a chance to travel to its target.

The easiest way to check for this would be to turn off your animation and test or even better yet use Show Tool or Show Tool Pro to look at and see how your animation is affecting things.

In regards to an "official" bones setup. No there isnt one. Why? Because anything goes. Make a valid skeletal rig in any 3D application and export it. Is there a tutorial for how to setup a skeletal rig? Once again no, this is all pretty standard stuff that you learn from the documentation that ships with your 3D application that the DTS exporter reads and exports. Torque really doesn't care how you have your rig setup, as long as it works and is setup properly with the DTS hierarchy.

#2 When i checked the model in show tool pro everythings ok!! to check further I stopped all the animation of my biped character and the non biped character. the biped character is firing projectile without animation which is ok!! but the non biped is chasing me but not firing any projectile!! any solution.
