collision events not triggering half the time with many bodies #1234

I have a pretty big project that I have made with phaser and using matter as the physics engine. I have an issue where, despite the bodies bouncing normally, the event for the collision is never triggered. I have tried with start, active, and end, and none of them work. The issue only exists when there are many bodies on the screen.

That sounds like a problem I had before. I use Tumult Hype, which uses Matter.js as the Physics engine. I was having trouble detecting collisions. To solve the problem, I didn't just check for A-B collisions, I checked for B-A collisions too. If you have Hype, the template here…

I'm not sure if that's the most optimal way to solve the problem, but the example game was playable after adding the additional collision checking.
