Thanks for the reply Guizmus, I may be misunderstanding you but the problem is that when i launch the ball with the left mouse button it should pass through the wall, and when i use the right button to fire it, it should collide with the wall and stay in the 'lane' that the player is in. So when i left click, the only way i've been able to have it pass over the wall is to disable solid collisions with the wall in general, which allows my player to also pass through(what i don't want) , the right click isn't a problem off course because i have that set to re-enable the collisions with the wall and thus it works fine even after left-clicking.
However if i was to left click to pass the ball over the wall, receive it back again and then before i right click to fire it inside the lane i go in the direction of the wall, i pass through it.
Only once i click the right mouse button again are the collisions re-enabled and that seems to be where my problems lie.
Also when i refer to collisions now, i'm referring to the solid behaviour and NOT the physics collisions,
because i've taken all physics behaviour out of the game due to unsatisfactory results with the way the ball moves.
