how to check if my object is on the "floor"?

I currently use if(myobj.body.velocity.y == 0) most time this works except if my object is on top of some object like this:

as you can see in the console the velocity.y is changed in every frame update even my obj is not moved, I think this can be fixed by setting some parameter for the world?

what caused this problem? and what is the right way to fix? thanks a lot.

@jcyuan I mean, you can:

1. set a type to your floor, body.type = ‘floor’
2. use collide events, and then use the flag to detect the floor: http://brm.io/matter-js/docs/classes/Engine.html#events

• collisionStart
• collisionEnd
• collisionActive

1. Set a boolean into your “player” to mark it “on the floor” indeed

What means tuts? My game doesn’t have gravity, and I use circles for the heros 😃
