How do I stop velocity cancelling when 2 object contacts?

[catccaatt]

Recently I was trying to learn a horizontal infinite running game. I set my player speed 20 at x direction, and I also set the ground speed -20 at x direction, then whenever my player fall to the ground, the player stops moving and the ground still moving at -20. What I want is the player also still moves at 20.

 

How do I make the two speed not canceling each other? like zero friction?

 

Thanks

Have you tried constantly applying the velocity in the update function?

function update() {  player.body.velocity.x = 20;}

If you are talking about forcing the body's velocity, I tried " player.body.velocity.x = 20 " in the update function but it doesn't work. Apparently, it is overwritten when two object collide.

There isn't any friction in Arcade Physics, only collisions which will affect the velocity on the axes affected. The closest thing to friction is the body.drag property, which allows you to reduce the velocity of the object over time on either axis.
