Changing the shape of the body (collision)

[Martiny]

Well, I have this shape in my game, and I'm wondering if Phaser would let me change the sprite body of my image so it would perfectly fit its shape. I couldn't find anything in the docs/examples. Maybe I overlooked?

 

 

 

 

I could make it smaller, but it would still be a square. How could I change it so it could be a circle, diamond, triangle, etc?

For the moment there isn't such a feature and the arcade collision is trough rectangles only, also no rotation.

That's sad ):

 

I could try to do something without Phaser to handle this type of collisions, but I guess I'll lose cool stuff like game.physics.collide() in the process.

Right.. ArcadePhysics is limited to AABBs only (although I am playing with Circles too at the moment). However Alvin has been busy experimenting getting p2.js running inside Phaser and it's looking very promising so far, so that will be a major focus for the 1.2 release (eta would be January 2014 I'm afraid). In the meantime it's totally possible to use a pre-made physics engine (Box2DWeb, p2.js, etc) and over-ride the Sprite.body property to point to one of those instead. It's not trivial work, but it shouldn't be that insane either.

Thanks for the response!

I've managed to get Chipmunk JS working at the minute so It's perfectly doable!

git link for you.

Lookout though, you're going to be trying to use documentation written in C to use it xD
