Hi all, i'm new to coding and this is my first phaser game so I'm happy to now be contributing to the community

I'm working on a game that the player gets killed if he gets hit by an asteroid and can also shoot the asteroid. The game was working ok before I tried adding the shooting, but now that I have only some asteroids are registering as overlapping for bot the bullets and the player sprite. Can you have two overlap functions for one group? That's my best what the problem may be.

Also, I'm not sure if my code snippet was satisfactory e.g. if there was things I didn't or should have included, so if you have any advice for that then please let me know.
Thanks for the help!

The first line in createAsteroids is "asteroids1 = game.add.group();" which replaces the old group; that means that any asteroids in that group aren't getting collided anymore. If the group already exists you don't need to re-create it. Try removing that line and creating the asteroid groups in your "create" function and see what happens.

@drhayes thanks a lot mate, that's worked like a charm!
