PyGame accurately detects image collision

In use Pygame When writing a game , One might encounter two Rect Objects collide, but there is a problem of space between objects , here , We will teach you a method to accurately detect image collision .

---

Suppose we have two images （ The type is Surface）：surface1,surface2

First , Get these two surface Object's rect：

rect1=surface1.get_rect()
rect2=surface2.get_rect()

then , Get their corresponding mask object , use pygame.mask.from_surface() Method , Use as follows ：

pygame.mask.from_surface(surface)

Enter yes Surface object , return Mask object

The code is as follows ：

mask1=pygame.mask.from_surface(surface1)
mask2=pygame.mask.from_surface(surface2)

Next , Collision detection , We need to use overlap Method , Use as follows ：

mask.overlap(other,offset)

mask It's a Mask object

other It's another one Mask object

offset It's a tuple , There are two in the tuple rect Of x Coordinate interpolation and y Coordinate interpolation

There are two kinds of return values , If it is a tuple, it means that it has collided , If None It means there is no collision

The code is as follows ：

offset=abs(rect1.x-rect2.x),abs(rect1.y-rect2.y)
if rect1.overlap(rect2,offset)!=None: #  Has collided 
    print(" Has collided ")

The above code is just an example , For reference , The naming does not need to be the same as above , Just follow the naming conventions

Today's teaching is here , If it helps you solve the problem , Welcome to pay attention ！ Thank you for your support ~
