Hi there, I am actualmente using this library but I am having lots of troqueles with trying to
a) Making an object jump
b) Trying to make a camera inside a collision box so my camera acts like an entity ans collides with other collision boxes
Do you have any recommendation aborto how to do this stuff, maybe an alreay created function or something like that?
