  • 0

What I’m trying to do is draw a gun for a fps game I am making but it always seems to be off. I know I am supposed to draw it last with depth test disabled. But i just can’t seem to get it to follow along with the view of the camera. Assume we are just drawing a triangle to represent the gun right now, with the base being at the players end. I have access to player position and the point where he is looking (used for gluLookAt) and I also have access pitch and yaw. And ideas on what to do?

    I’m not an expert but I would try something akin to the following for drawing the gun:

    #If not already in modelview mode
glMatrixMode(GL_MODELVIEW) 

#Push the current modelview matrix onto the stack, leaving us working with a copy
glPushMatrix()

#Translate forward to where we want to draw the gun
glTranslatef(0,0,dist)

#Draw the gun starting from this position, translation may need to account for offset so that it is centered correctly
gun.draw() 

#Get rid of our modified modelview matrix and return to the original so that the camera is in the correct positon
glPopMatrix()

    The best guide I have found for understanding OpenGL geometry is http://www.songho.ca/opengl/gl_transform.html

    Good luck! 🙂
