In this guide, we will be taking a look at how to utilize mouse input with PyGame.
To retrieve the position of the mouse, you can use the following line:
mousex, mousey = pygame.mouse.get_pos()
Of course, with the above line, you can access the x position of the mouse with mousex, and the y position of the mouse with mousey. Ensure this line is executed within the game loop, either in a dedicated update function, or directly within the loop.
Mouse clicks can be listened to by capturing the pygame.MOUSEBUTTONUP event. Let’s try this. In your update function/game loop, add the following code:
for event in pygame.event.get(): if event.type == pygame.MOUSEBUTTONUP: print("Mouse click detected.")
However, what if you want to distinguish which mouse button you clicked? You can use the event.button property to determine which mouse button was clicked. Here is a list of possible integers event.button can be:
For example, to detect mouse right clicks, you could add the following inside your pygame.MOUSEBUTTONUP if statement:
if event.button == 3: print("Right mouse button clicked")
If you wanted to check if the user is scrolling up, you can add the following code:
if event.type == pygame.MOUSEBUTTONDOWN: if event.button == 4: print("Scrolling up")
To scroll up, you can check if event.button is equal to five.
if event.button == 5: print("Scrolling down")
