What is a/the more/most accurate, and shorter way of checking if my actor (Pengu) is colliding with a different one (Box/Block/Cliff), and what should I change in the code below? Right now the Pengu doesn't look like it's always bumping into these things, it can sometimes be inside the image.
P. S. danpost, if you don't know of a solution (like last time), then don't "Post a reply" and make people think that the problem/issue is solved, if you do know a solution then don't hesitate to share it with me.
Here is my world class code:
Here is my Mover class code, which Pengu extends from and has all the collision checking methods:
Here is the Pengu class code:
Here is the Box class code (collision object, it has variables that need to be checked for/if collision):
Here is the Block class code (collision object, it has variables that need to be checked for/if collision):
I didn't post the cliff class code, because the only thing that it has to do with collision is the picture, no coding.
