Can some one help me with my camera problem. I rotate the camera around a ball and it goes through my levels walls.Is there a way so that it doesn't do that or it stops when the camera hits the wall.

this is the code i am using for my camera



ay#= object angle y(2)
X# = Object position x(1)
y# = OBJECT POSITION Y(1)
Z# = Object position z(1)

Rem get new camera position and store in cZ# and cX#
cZ# = Newzvalue(Z#,aY#-180,100+move*2)
cX# = Newxvalue(X#,aY#-180,100+move*2)


position camera cX#,object position y(1)+270-cmove/2,cZ#-500+cmove

Point camera X#,object position y(1),Z#

If they are loaded and placed wall objects or DB primitives you could create an invisible cube at the camera's position and use the collision commands to stop the camera if the cube hits the wall.

ok i will try that but I never did that before so can you point me in the right direction with the coding. I heard the collision commands are hard to use.

Your camera is positioned using variables. If you create a cube of size 5 and place it at the same position as the camera, you effectively place the camera inside the cube.

Unless you alter the cull setting of the cube, the insides of the cube will not be drawn and it will therefore be invisible to the camera.

Every time you move the camera, use the same X,Y,Z position variables to position the cube on the very next line.

As for collision, all you need is very basic collision. As you didn't respond to my comment about exactly what your walls are made from, it's impossible to be any more specific. There's a tutorial on basic collision here:

http://forum.thegamecreators.com/?m=forum_view&t=99497&b=10

Check out tutorial number 10. I know they are for DBC, but this applies to DBP's collision commands too.

Sorry about that. The walls are loaded in X format (walls.x). Thanks for your help

The link you gave me number 10 tutorial doesn't work it sends me to a blank post thought you might want to know.

Oops - yes I forgot about that! Doh!

The post was moved and I forgot to update the links. Here you go...

Loaded .X files should work the same as DB primitives as far as the tutorial goes. Just post back here if you have any problems.
