Camera not smooth enough?

programming

I’ve got the camera to move with the character ok :slight_smile:

However, when he runs down a slope, the camera starts to get all jerky, but what makes this more confusing is that when the slope is really steep, the camera is not jerky going down but my character doesn’t exactly use his run animation down the slope, but when the slope is NOT steep the camera gets all jerky.

Here is a preview of the game.

Here is the code off the “going down” part of the camera:

onClipEvent (enterFrame) {
	this._visible = false;
	// when the character touches this, move the whole camera
	if (this.hitTest(_root.player)) {
		// move the camera by this much every time he touches
		_root.cam._y += 4.5;
		
	}
}

Here is the camera code:

function camControl():Void {
	parentColor.setTransform(camColor.getTransform());
	var scaleX:Number = sX/this._width;
	var scaleY:Number = sY/this._height;
	_parent._x = cX-(this._x*scaleX);
	_parent._y = cY-(this._y*scaleY);
	_parent._xscale = 100*scaleX;
	_parent._yscale = 100*scaleY;
}
function resetStage():Void {
	var resetTrans:Object = {ra:100, rb:0, ga:100, gb:0, ba:100, bb:0, aa:100, ab:0};
	parentColor.setTransform(resetTrans);
	_parent._xscale = 100;
	_parent._yscale = 100;
	_parent._x = 0;
	_parent._y = 0;
}
// make frame invisible
_parent._visible = true;
// Capture stage parameters
var oldMode:String = Stage.scaleMode;
Stage.scaleMode = "exactFit";
var cX:Number = Stage.width/2;
var cY:Number = Stage.height/2;
var sX:Number = Stage.width;
var sY:Number = Stage.height;
Stage.scaleMode = oldMode;
// create color instances for color 
// transforms (if any).
var camColor:Color = new Color(this);
var parentColor:Color = new Color(_parent);
// Make the stage move so that the 
// v-cam is centered on the
// viewport every frame
this.onEnterFrame = camControl;
// Make an explicit call to the camControl
// function to make sure it also runs on the
// first frame.
camControl();
// If the v-cam is ever removed (unloaded)
// the stage, return the stage to the default
// settings.
this.onUnload = resetStage;

Finally here is the “slope” code off the main character:

	///// this is the sloping code
	grav++;
	_y += grav;
	while (_root.ground.hitTest(_x, _y, true)) {
		_y--;
		grav = 0;
	}

If you need anything else just ask

Thanks in advance
