I have this problem. Let’s say i want to move a character when I pussh Key.RIGHT, the problem is, from the first time i push it, till the movement it’s done, there’s a little lag. It’s the same as if you push BACKSPACE… it doesn’t erase everything instantly, if you have this key pressed for a while, it start erasing. I have this problem with the movement, ir doesnt move instantly.

How can I fix this ?? I hope you understood…

this is the code i have…on the first frame of the main timeline:

```auto
man.onKeyDown = function(){
	if(Key.isDown(Key.RIGHT)){
		man._x += vel;
	}
}

```
