HI I have added this bit of code to my game so that the players score increases when they find a pickup.



The thing is it is only the camera that moves around the level giving a first person feel to it. So my camera does not have a object number and so won't react to "if object collision (9,1)"

is there any way to get this collision to work with the camera?
or maybe even how to assign the camera with an object number?

Thanks

Place an object at your camera and hide it? Maybe.

How would I make it so the object stays with the camera as it moved around?
Thanks

To add on to Brendy boy and gunslinger...

It would probably be wise to setup a UDT (user defined type) so you can store your coordinates in that and make any changes to those properties and then send those properties to place the object.

For instance:



This way you can use set and use that information for whatever calculations you want and don't have to worry about pulling that information. You can also use that same idea to create an imaginary bounding box around the camera that you can then run fast collision detection on.

Hope that helps

Before main loop:

make object cube 1000,1
hide object 1000

in main loop: (not sure how this would interact with your current movement system with the camera)

`fps style movement
rotate camera camera angle x ()+MouseMoveY( )/2.5,camera angle y ()+MouseMoveX( )/2.5,camera angle z ()
rotate object 1,camera angle x (),camera angle y (),camera angle z ()
position mouse 0,0

if keystate (17)=1 then move object 1000,0.2
if keystate (30)=1 then move object left 1000,0.2
if keystate (31)=1 then move object 1000,-0.2
if keystate (32)=1 then move object right 1000,0.2
position camera object position x(1),object position y(1),object position z(1)

if object collision(gem,1000)
inc score,1
delete object gem
endif


Hope this helps.
