It would probably be easier for us to help you if you post some code so we can tell if you have made any misstakes.

And please tell us what version of AppGameKit you are using.

Also, how are you deciding that GetPhysicsCollision not working?

From your GameUpdateBall function, you are both manually setting the ball sprite and then trying to apply an impulse to it.

The two don't work together. Either you totally control the position of the sprite (not using impulse or force) or you let the physics engine handle all of it (not using setspriteposition).

Ok,
the version is 1088, not the GetPhysicsCollision works I simply determined by which I have to print the return value and the display was also absolutely unique collision of two dynamic or dynamic and static sprites always 0. SetSpritePhysicsImpulse works absolutely perfectly and the way I though as I used there. When I program the collision detection with a few if's even it works so well.

Well, I have solved my problem itself,
you must simply call GetPhysicsCollision before SetSpritePosistion. Then everything works as I programmed it.
Is maybe even a tip for others

That makes perfect sense (now that I think about it).

Because it is entirely possible that the sequence is resetting the sprite position first, which clears the collision information.

The physics processes won't update immediately upon doing things. All actions and checks take place when the sync() command is called.

That is actually a great tip, because I have heard it over and over that SetSpritePosition does not work with GetPhysicsCollision, and now you proved everyone wrong.

I vote that this tip be added to the documentation page for both commands.

Thanks and cheers,

I agree AS, that's very important information. I wasn't aware there was an issue but maybe I have been using the commands in the right order purely by chance up until now.


this.mess = abs(sin(times#))
