Ok, ive done the gravity and i have made it where the character can only jump if yvelocity = 0. When the actor collides with the ground, it changes yvelocity to 0.
Now, i need to make a platform that my main actor can jump upward through, and land on. If i use the same colision method as i did with the ground, my character gets stuck on the top of the platform, he has to "hop" upward untill hes through the top collision layer.
not to mention that that way of doing collisions with the ground dont work well =\ if he has high yvelocity when he his the ground, he kinda goes into it
sorry if thats a bit hard to understand, im not very good with words
