Collision Help
-
I’ve been creating a flappy bird style game. I’m new to programming, and I can’t get the bird to pipe collision to function. It seems as if the bbox on everything is massive. Any help?

See this post. it should get you on the right track
im curently working on this tutorial

I’ve looked at the code and I can’t figure out a way to get it to work. I know the code could use a lot of work but can you run it and see if you could get the pipe collision to work? There’s a code at the bottom with a note.

Yes sir just give me a bit to look over everything

Thank you

One problem I see:
if self.game_running == True: self.add_child(self.score_label) self.add_child(self.player)This code gets called every 1/60th of a second. You shouldn't be adding player as a child each frame -- it should already be added once.
-
@FLAME130 what isn't working? Is it exiting immediately?
Where do you define exit()?
Have you tried printing the bbox's?
Also, maybe first try with ShapeNodes for player and pipes -- sometimes if your image is not prepared right, the bbox might be larger than you'd expect, for instance if the icon has a large clear border
-
Oh, okay thank you. I didn’t want it to exit I just set it to that so I can see the change immediately. Do you have any examples of shape nodes?
