globalToLocal(); syntax?

[4urentertainment]

I'm using AS2 and this is my code:

onClipEvent (load) {
	var myPoint:Object = {x:_root.wall._x, y:_root.wall._y};
    this.globalToLocal(myPoint);
}
onClipEvent (enterFrame) {
	if(this.hitTest(myPoint._x,myPoint._y,true)){trace("lolz");}
}

but nothing happens.

So I have a wall on the main timeline, and a movieclip in 3 movieclips. I want to test if they are shapeFlag hitTesting. How do I do that?

Yeah uh note how 'myPoint' has properties x,y, not _x,_y.
The conversion is not necessary there because hittests use global coordinates.

[4urentertainment]

But when I just say:

if(_root.walls.hitTest(this._x,this._y,true)){trace("lolz");}

It never does anything. However when I say:

if(_root.walls.hitTest(this)){trace("lolz");}

It always works since they are four walls in the movieclip wall surrounding the player. So what I want is to change the _root walls to local coordinates or what I'm trying to hitTest to convert it to global coordinates. How?

The shapeflag hitTest seems to work fine to me, although it won't register until the MC is buried in the wall.
Adapted version here

try this:

onClipEvent (load) {
	var myPoint:Object = {x:_root.wall._x, y:_root.wall._y};
    this.globalToLocal(myPoint);
}
onClipEvent (enterFrame) {
	if(this.hitTest(myPoint.x,myPoint.y,true)){trace("lolz");}
}

Still doesn't work.

I'm pretty sure I'm doing something very wrong... But what?

I mean if I have a movieclip inside another movieclip. player2 is inside player1.

player1's x is 200
player2's x is 0

Now I want to convert that 0, to the _root coordinates where it will be 200 as well...

Denvish, the fla you sent, if I am not mistaken, the hitTest was on the player and the walls which were on the main timeline. What if the player was in another MC. How do I shapeFlag hitTest then???

Change all the _x and _y values in the enterframe code to _parent._x and _parent._y
Or just put the code on the external MC, instead of the nested one

The thing is, the external one has other things with it, and I only want on the nested one. If globalToLocal is impossible or something, I'll just have to get the nested movieclip on the main timeline.

So no one knows the syntax for using globalToLocal?

Take that Denvish! I hate you. >:c

4ursomething - learn to use, er, ..anything at all, God please?, before you whine about coordinate spaces.

onClipEvent (enterFrame)
{
  var p = { x : _x, y : _y };
  _parent.localToGlobal (p);
  
  trace (_root.walls.hitTest (p.x, p.y, true));
}

I'm positive you should have the capacity to paste this without fucking it up.

Great timing, I actually just figured out how to work it with this code:

onClipEvent (load) {
	var p = {x:_root.player1.player2._x,y:_root.player1.player2._y}
	trace(p.x);
	_root.player1.player2.localToGlobal(p);
}

onClipEvent (enterFrame) {
	
	
	trace(_root.player1._x);
	trace(p.x);
}

Thanks anyway.

Can you spare me the constant facepalming? At least pretend to be happy to understand, and don't post code showing you twisted some shit like a hapless dolt until it somewhat worked. You hapless dolt.

[Denvish]

lol PMT much Gust?

[4urentertainment]

Well I'm not a total AS noob. I was able to code this.

Without copying a single line (except for the part where the light stops at the walls, but I didn't copy that either, understood it from a tutorial. Not too sure about the trigonometry part though.

That counts for something, right?

Controls:

Move with WASD, shoot with mouse, change weapons with Q,E, turn off light with F, run with SHIFT, open doors with space.

Right?
