Well you could always check collsion between object to object by placing an object like a gun in front of the camera.

Cocacola and Pepsi aren't that differnt. Deal with it.

I'm using sparkys collision plugin, and all i do is a sphere collision check on the camera's x,y,z , and use the usual collision setup for it.

Further on my stuff at...

Stick your camera on a simple object like a sphere and use object collision commands for good looking 'Camera Collision'.

+ Code Snippet

make object sphere 1,10
make object cube 2,30
position object 2,object position x(1),object position y(1),object position z(1)+100
do
if upkey()=1 then move object 1,0.25
if downkey()=1 then move object 1,-0.25
if leftkey()=1 then turn object left 1,1
if rightkey()=1 then turn object left 1,-1
position camera object position x(1),object position y(1),object position z(1)
yrotate camera object angle y(1)
if object collision(1,2) then set cursor 10,10 : print "collision!"
loop

Let the games begin.

Your positioning is wrong

Try positioning the object at 50,50,200 (where the camera is) and then work from there. Currently you have positioned the object out of your maze.

Whoops meant 50,0,200. Anyway, try that, and if it still doesn't work, change the object to a sphere and see if you can see it. If you can, then change it back to a gun. If you can't see the gun then your model needs to be re-sized using the SCALE OBJECT command.
