How to bind a weapon before camera

[thatax]

just like counter-strike and half life,bind a weapon in front of the screen.

Search the forum if you've got a question because most of your questions will have been answered before.

Basically just use this:

gun_node->setParent(camera_node);
gun_node->setPosition(vec);

where vec is a position RELATIVE to the camera's position which will align it nicely to be on screen, this is just something you have to find with trial and error based on the gun model you're using.

But wasn't it that unless you use the default FPS camera, the gun wont rotate along with the camera and you have to do it manually?

Not that i know of... but possibly, i've not used anything other than the FPS camera for this sort of thing.

It's not really a difficult challenge to work out how to get it to stay there. If you have the cameras current direction, you can point the gun in that direction at all times. Then, using the cameras current position and rotation, you can work out exactly where the gun needs to go. It's the kind of thing you just need to sit down and work out.

Yes, since scene node rotations and camera targets are independent. However, it's probably a safe assumption that this poster is using an FPS camera.
