Hello all,

I might just be overlooking things but does AppGameKit have a method for applying force to an object based on the angle? Say for example I wanted to use physics to control a player ship. I want the propulsion to be physics driven within AppGameKit using force. This force is applied appropriately on the object based on the angle the object is pointing effectively allowing the player to just press forward and then left and right as needed for direction change.

Again my apologies if this is somewhere Im overlooking, been a long day

Yes, look at the setSpritePhysicsForce and setSpritePhysicsImpulse commands. I would guess the second suits your needs more.

If you want to apply a force based on your sprite angle then use something like:


You may need to add or take away some factor of 90.0 to your sprite angle depending on what angle the 'ship' is at in the image.

Would that type of physics work for lets say a motorcycle? Also, would it be possible to have it set that if parts of the sprite collide with anything it sends the player back to the last checkpoint.

Cheers.

God help me, Please.

You'd be better using motors for a motorcycle but theoretically yes that would work.

Checking for contacts and collisions can certainly be used the way you are thinking.
