If i know the x,y,z position of the camera and the angle it's pointing at, how could you work out the x,y,z position the bullets would end up at. Say the gun (AK47) had a range of about 400 units. This could change if you where just using a pistol with a range of about 100 unit. Hope i've explained it ok

Thats quite easy, im not sure if the syntax is correct (im not at my DBC pc )

you point the bullets in the right directions and move them



now you only have to move them when they are fired

Thank for the reply Emperor Baal.

I'm probably me being a bit thick but i dont actually want to move an object. i just want to get the x,y,z of the maximum range the bullet could travel. My thinking behind this is that after you get that position you could use something like the intersect object expression to see if a collision occurs.

the below formula gets you the distance in units(rounded to the one's place) between the bullet and the camera.

Distance=sqrt((object position x(bullet)-camera position x())^2 + (object position y(bullet)-camera position y())^2 + (object position z(bullet)-camera position z())^2)

then use this code to kill the bullet when it the distance gets to 4000

if Distance>4000
add your commands to replace the bullet (like hiding and repositioning)
endif
