Hi,

I´ve get two angles. One for a ball(it moves straight forwad). The second angle returns the angle of the next wall. Now the angle of the ball should be turned like a ball rolles on a buillardtable. If the balls angle = 0 and the walls 90 then the ballangle should be turned to 180, if the ballangle = 10 then it should be turned to 80. But not only at the 90° wall. The walls can get all values up to 360. How can I manage this ?

Ok, it´s to difficult, so here comes my new question. How can a vector be mirrored by an other vector ? Both got the same length.

Which version do you have? This problem would be easily solved by simply engagine the physics engine.

Further, what do you mean by "mirrored"?

i know what u mean!!! use Bounce" look it up in the manual, it will give u more details!
but if ur going to use the physics engine then the engine does that itself, no extra scripting required.

hope this helps,
Alex

ohh!! I get it, sort of like a brick attack deal, when it hits the wall it bounces off!

Say we have the following:

BallVector(0,3,0) <-- hit's a wall at the bottom

if (ball_hits_a_wall)
give the vector a random X and/or Z value between the values X and Y.. (this assures it doesn't just change directions)
Invert BallVector.
move it.
