[SOLVED].....Hooray
Hi all

I am playing with AppGameKit and a brick breaker game as a tutorial! Thanks to Ancient Lady, got the ball moving and bouncing ok.

However, no matter what velocity i set my ball to it is always 35,35 or -35,-35?

I set the velocity outside of the main loop as the ball has no friction, minimal mass? Damping is zero??

The ball stays at a constant speed, which is good, but if I set the velocity higher:


No change in ball speed? What am I doing wrong.???
Tier 1 (still cannot get Tier 2 to compile-anyone fancy converting the .libs to .a for mingw???)

Constantly seeking!

There's a good chance this is caused by the physics scale. There is a maximum velocity based on the scale of the physics simulation. I reached it at about 600 at the hackathon and had to use "setPhysicsScale" at around 0.2 I think to get the kind of speeds that I wanted.

Make sure you call it before creating any physics sprites or any other physics calls or anything already created will be scaled too.
