Collision in custom 360 movement

[Pancra]

Hi, again with the freaking 360 movement.

The problem now is that I don't know how to stop the movement when the character collisions to a wall.
Another thing...must I make those 4 "collision lines" that move with the character?, dont know if you understand...
Thanks

4 collision lines? What are you on about?

[DavidN]

"Collision lines" refers to the collision detectors that are placed around the character so that it can be stopped when it reaches a wall.

Having collision detectors is certainly one of the easiest ways to do it, though you may not need them if your engine uses fastloops.

[Pancra]

okey...I meant collision detectors.
I dont really know how to use fastloops or why would I use them.
But my main problem is that I don't know how to deny movement to the character when it is walking against a wall.
I used the 360º movement using Sin and Cos, but how do I restrict movement over walls?

[DavidN]

It's a bit difficult to say without looking at the whole engine - it varies so much. But the basic idea is to detect when a player collides with a wall as a result of its movement, and if so, to either prevent it from moving in the first place or to move it back by the same amount that it moved.

[Pancra]

ohh..wait...right, preventing to move if is in collision.
So I have to say:
+ When player press "up" and is not in collision: move up.

Thanks davidn.
