CheckCollision

CheckCollision

Funkcja odpowiada za sprawdzenie czy wystąpiła kolizja między obiektami odpowiednich typów. Jest to zrobione za pomocą kilku pętli sprawdzających mapy konkretnych typów Spritów i wywołujących funkcję IsCollision dla par nich. W momencie otrzymania True (czyli wystąpienia kolizji) uruchamiane są odpowiednie funkcje dla tych obiektów.
