arcade physics velocity movement is per second, but doesn't seem so

[mickeyren]

this is how i would move the sprite:

player.body.velocity.x = 100

and no other factors are set eg, gravity 0, drag  0 etc.,

but you can notice that it's not exactly moving 100 pixels per second:

Any idea why?

It should be pretty close.

You may to add game.forceSingleUpdate = false.
