How to find current position of camera

| How do I find the current position of the camera during game play, does anyone have any idea how that could be done? I just need the position to show up on the screen when you click a key, or something like that... Any help would be apreciated, Thanks! |

| X# = EntityX( camera) Y# = EntityY( camera) Z# = EntityZ( camera) |

graphics 3d,800,600,0,2
camera=createcamera()
;mesh = loadmesh("some test environment")
repeat
if keydown(200) then moveentity camera,0,0,1 ;move forwards on pressing up arrow
if keydown(208) then moveentity camera,0,0,-1 ;move backwards on pressing down arrow
if keydown(30) then moveentity camera,0,1,0 ;move camera up if A pressed
if keydown(44) then moveentity camera,0,-1,0 ;move camera down if Z pressed
if keydown(203) then turnentity camera,0,1,0 ;turn left on left arrow key pressed
if keydown(205) then turnentity camera,0,-1,0 ;turn right on right arrow key pressed
updateworld
renderworld
text 0,0,entityx(camera,true)
text 0,15,entityy(camera,true)
text 0,30,entityz(camera,true)
flip
until keydown(1)
freeentity camera
end
something like that should help hopefully. |

| Both did not work... The first one I tried made no sense to me... The second one looked promising, but When I used it, it didn't work... Does the code print the location of the camera on the screen? Or is there something I'm Missing? |

| exactly as mr, Bilip show ya.. X# = EntityX( camera) Y# = EntityY( camera) Z# = EntityZ( camera) these are coordinates for your camera, now..you should make your camera globaly accessible ( Global Camera=Createcamera() ) and of course, in example above i assume that your camera entity has name 'camera' as it is in example..if not, use proper camera handler name, accessible globaly |

| For Matty's example, change the first line graphics 3d,800,600,0,2 to this graphics3d 800,600,0,2 |

| Thank you Pongo for clearing that, It works nicely now! I'm going to stick with it. Thanks. ☺ |

| Just ensure your camera is given a global variable :o) |
