FlxG.camera.targetOffset

broccolu

Is there any way of using FlxG.camera.targetOffset? It seems to be read-only. I can make the camera follow a dummy object instead, but it seems to lag behind the actual target for a fraction of a second, causing the sprite to jitter.

Another problem- whenever I use FlxG.watch it shows something like:
null._myVar null
Any idea what I'm doing wrong? Eg:

class PlayState extends FlxState
{
	var _myVar:Int = 123;
	
	override public function create():Void
	{
		FlxG.watch.add(_myVar, "My Variable");
		super.create();
	}		

	override public function update(elapsed:Float):Void
	{
		super.update(elapsed);
	}
}

Like with a lot of FlxPoint fields in the API, FlxG.camera.targetOffset is read-only - however, this only affects the reference to the point itself, so you can't assign a new point to it. However, you can still change the values of the point, for instance via FlxG.camera.targetOffset.set(x, y), or by setting its x and y properties directly.

Aha, now it makes sense! Thank you very much!

Oh, and regarding FlxG.watch usage: you're using the API incorrectly. The first argument for add() is the object that contains the variable, the second argument is the variable name:

http://api.haxeflixel.com/flixel/system/frontEnds/WatchFrontEnd.html?#add

This should work:

FlxG.watch.add(this, "myVar");

Ha ha, I knew I'd feel stupid once I realized the mistake! It was worth it, good stuff.
