Hello all,
sorry if this question has been raised before, spent a bit of time searching but couldn't find what I need. Basically I am working on a game with ships/robots that will have mount points for weaponry and equipment and will be able to move and rotate in all directions. My question is what is the best or simplest way to define a mount point on an object or model, secure the weapon to the mount point, and make sure it behaves correctly, i.e. moves and rotates along with the model it is mounted on. I am using 3ds max to make models if this helps.
Thanks

I'm assuming you're using bone animation for your main character, yes? Add a "dummy" joint to the skeleton at the point where you want the weapon to be held. When you export the model, each joint will have an index, so make sure you remember which index the dummy joint has.

After that in your code, use this to attach the gun to the joint:

dbGlueObjectToLimb( objectID , TargetObjectID , JointIndex )

Note that dbPositionObject() is relative to the joint position and rotation. If you see that the gun is crooked, then open up your character model again and rotate the dummy joint to compensate.

Thanks! After a bit of fooling around in 3dsMax I figured out how to do joints, just normal bones. Putting that model in was easy and adding another object to the joints using the command worked a treat. Potential pitfall was rotating and pointing a glued object didn't work but a work around is getting the limb position of the object using the dbLimbPositionX/Y/Z commands, positioning your turret object at those coords and doing any rotations and points you want. I plan to use my new found knowledge to put turrets on ship models and point them at targets.
