Hello! I'm designing a space shooter game, and I'm trying to position my camera behind the ship. Basically, wherever the ship is pointing, I need the camera to be in the opposite direction(+180 with a dbWrapValue, most likely.) and at a set distance. The distance is the Hypotenuse/Radius, and the angles are based off of the objects angles.

Any help?

Here's my progress.

This should be in the darkGDK forum, Shouldn't it?

How about just saying "rotate camera object angle x(1000)+180, angle y(1000)+180, angle z(1000)+180" In your do loop? I use DBPro but it should be almost the same in GDK.

Eh, that would only get it pointing in the right direction.
I can get it pointing to the right spot, it's just a matter of positioning it in the right place.

Position the camera in the same place as your object, then use dbSetCameraToObjectOrientation(), then use dbMoveCamera() to move it backwards the distance required.

Here's a thread for Newtonian flight, just in case it may be useful:

Awh, thank you so much for the reply.

I had figured that out a few hours after your reply.

Had I checked here, I would've gotten it sooner, I guess my own ambitions got me the answer sooner than my dependence on others. Thank you very much though, I really do appreciate it.
