I'm making a rail shooter where the ship continually moves forwards, and I want a way for there to be sliding collision in the game without stopping the ship completely. My idea is...



Like Example B, you'd rotate the collision boxes 45 degrees so that everything slides off to the side. I absolutely must have the ship moving straight down the Z axis, just changing its X and Y positions to aim, it's a key element of both the gameplay and the controls, so I can't just rotate the direction the ship is headed by 45 degrees. Currently, that means my sliding collision effects work like Example A, the ship runs into the collision box and just stops. So, I looked for a way to rotate the collision boxes and still implement sliding( by rotating all effected boxes by 45 degrees) but I've had no luck. So, any suggestions?

Download Sparky's Collision dll, or get NGC, or look into Kensupens/G-Man's collision routine. Plenty of methods out their, using box collision isnt one of them (when dealing with polygonal, non-primitve objects).

However if its a rail shooter, and the only change in position is on the x and z axis, you could just check if the object goes to far to the left, if so move it right, if too far to the right, move it left.

Ah, but this is to apply for obstacles on the rail, not to keep the object within the rail area itself. Can you give me a link to some of these though? I don't have the slightest idea where to look.

EDIT: Ahaha, didn't realize that was the topic below this one >_>
