Ok, as everyone might know, I have been working on an art based game for some time now, and I have yet again run into a another problem with the ground. I want to create some moving platforms that go side to side or up and down, and I want the character to be able to walk up and down slopes. My code for the ground goes like this:

```php
  
onClipEvent (enterFrame) {
	if (_root.limits.hitTest(getBounds(_root).xMax, _y, true)) {
		this._x -= 2;
	}
	if (_root.limits.hitTest(getBounds(_root).xMin, _y, true)) {
		this._x += 2;
	}
	if (_root.limits.hitTest(_x, getBounds(_root).yMin, true)) {
		this._y += 5;
	}
	if (_root.limits.hitTest(_x, getBounds(_root).yMax, true)) {
		this._y -= 5;
	}
}  

```

If any one would like to help, please reply. thanks in advance :thumb:.

how about setting a real limit instead of testing and pushing your character back up?

character.\_y = Math.max(ground.\_y, character.currentY);

Now you have set a limit that the character wil never be able to cross, without limiting other free movement. (this is actually just a if/else statement, but looks nicer)

In this example character.currentY is variable (your character jumping around and stuff), ground.\_y should be pretty constistant, or not, your choice 😉
