How do I stick a 3d object that I have created to screen cooordinates?

like a gun in an fps? so I can be pointed in any direction and the gun is still there.

I'm using DBPro

you want to offset it from your camera a little below and out front so you can see the barrel, then have it move as you camera moves

The help files are your friend. If you have not read them from cover to cover, you'll never learn the syntax of the language.

BTW, this is not the only method. You can also dynamically position the gun relative to the camera each sync. While this is more coding, you can achieve more control as well. (Weapon bobbing, recoil, switch animations, etc.)

TAZ

LOCK OBJECT ON
This command will lock the specified 3D object to the screen. Locking objects to the screen commands the object to completely ignore the camera's influence. A locked object will be positioned as though the camera had never been altered from its default orientation. To make locked objects visible, simply set the Z position to a significant positive value. The Object Number should be specified using an integer value.

Right. The problem I'm having with LOCK OBJECT ON, is that it doesn't actually move the object. This means I can't do things like place a bullet at GunX#, GunY#, GunZ#, set the angle to GunAngleX#, GunAngleY#, GunAngleZ#, then move the puppy off.

The problem is one of math, how do I determine the same position relative to the camera despite where it is facing? I'm pretty sure that I'm going to use NewXValue, NewYValue, and NewZValue, but I don't know how to use them. The Help files say they replace Sine/Cosine, but my Math classes never taught me how to use Sine/Cosine either, so I'm somewhat at a loss.

Can somebody help?

i am working on a fps and looking at my code i just used this peice of code to have the gun be in the same spot no matter how the camera moves unless i specificly say move the gun object to say getting it to bobble but if you just want the gun to be in the same spot no matter where the camera moves up/down left/right just load it like this
