Why Does My Pygame Collision Detection Always Return True, and Why Is My Image Position Always (0, 0)?

Troubleshooting Collision Detection and Image Positioning in Pygame

Collision Detection Issue: Always Returning 'True'

One of the most common reasons why a collision detection function returns 'True' when it shouldn't is using the wrong coordinate information. In your code, the Ball and Obstacle sprites have additional x and y attributes, but the get_rect() method of the Surface object does not automatically update its position based on these attributes.

Solution:

To resolve this issue, you should set the position of the rectangle manually using the topleft keyword argument when calling get_rect():

Image Positioning Issue: Always Returning (0, 0)

By default, the coordinates of the Surface object are always set to (0, 0), regardless of where it is displayed on the screen. When blitting the image onto the game display, you need to provide the correct coordinates where you want it to be drawn.

Solution:

You can simply use the coordinates stored in the rect attribute when blitting the image:

Additional Tips:

• Use a pygame.sprite.Group to manage sprites. It simplifies drawing and collision detection.
• Avoid using additional x and y attributes for sprites. Instead, rely on the rectangle's position for position information.
• Check the documentation thoroughly for functions like get_rect() to understand their behavior and requirements.
