Alright, so I have this cube. And I'm following it. And I wanna turn with it. The way I do it I turn, but I stay in the same X and Z which I don't want. How would I do that? Am I clear enough? It's gonna be something about going around in a circle around the cube I'm guessing.

Thanks,
Matt

No see, that just rotates the cameras orientation, i wanna move it to, so it stays the same exact distance from the object, get it?

[edit] I just got the idea of making a limb off to the side and putting the camera there, hang on lemme try it out [/edit]

Well it's getting really frstrating. I added the limb, and offset it, then set i need to link it in order. so i linked it so 0, guessing thats correct because theres no limbs on a ficking cube. i really need some help on how to set up the limb system.

To let the camera follow an object, use newxvalue and newzvalue like this:

to place the camera at dist# distance from object b, and at h# height above object whose y-angle is ang#. Is this what you are looking for?

Looks like it would work but it don't. I can't show my code because it's on another pc (with no internet or floppy drive)

The following code is taken from the BlueIde code library so I am assuming it is RobK's work (although I may be wrong). I believe it is what you are seeking.

Because I'm using a two camera system and it would be easier to do it my way.

[will test code later]

I have to agree with Clueless. Set camera to follow has easy to use distance and angle control which makes orbitting a cube a snap, just add a point camera command to keep it focused on the center. Plus, you can optionally specify which camera to act upon so you can set each camera differently.

Of course, I don't know the full scope of the problem. So, there might be something preclude the use of set camera to follow.

position camera [Your Camera here], object position x( [YOh] ), object position y( [YOh] ), object position z( [YOh] )
rotate camera [YCh], object angle x( [YOh] ), object angle y( [YOh] ), object angle z( [YOh] )
move camera [YCH], [A negative distance that should be somewhere around the height of your character]

ie.,

position camera 1, object position x( 1 ), object position y( 1 ), object position z( 1 )
rotate camera 1, object angle x( 1 ), object angle y( 1 ), object angle z( 1 )
move camera 1, -200

I like adding + 30 to the X angle; it gives a nice downward slant.

Cheese!

It supports multiple cameras, at least in the version of DBP I've got... maybe that's still not what you're after though. At least you've got a few different methods to choose from.
