fliping horizontal?

[yeps]

hi, ive been working on a fairly simple game... with a bunch of really annoying coding.... and now im trying to flip a character according to where he is pointing... and it is just driving me crazy....

could somebody please take a look at this for me, i just cant seem to get it.

thanks a bunch

Just post the code, nobody wants to download a fla.

Since you've been on FK for nearly a year, I assume you already know that _xscale = -_xscale; is the code to flip a movie clip horizontally?

[Ray Beez]

I do _xscale *= -1;

[yeps]

hey... im sorry

i know how to flip it and every thing.... its just that this problem you may have to see...

um... i'll put a swf up on image shack for you though

and here is the code on the arm...

onClipEvent (enterFrame) {
	if (_root.guy._xmouse<20){
		_root.guy.gotoAndStop(1)
	}
	if (_root.guy._currentframe == 2){
		this._x = 18
	} else {
		this._x = -18
	}
	if (angle2<-79) {
		this._yscale = -100
		_root.guy.gotoAndStop(2)
	} else{
		this._yscale = 100
		_root.guy.gotoAndStop(1)
	}
	angle2 = Math.round(angle/Math.PI*180);
	angle = Math.atan2(opp, adj);
	opp = ((_root.guy._ymouse-this._y));
	adj = -1*(_root.guy._xmouse-this._x);
	this._rotation = -1*angle2;
}

i tried to use _xscale but sense the angle flips every time the body flips... it just keeps going back and fourth and i couldnt get it to stop... does that make sense?

[ImprisonedPride]

I do _xscale *= -1;

Yeah I was going to say, wouldn't that be more efficent because what if something prior changed the _xscale to like 30?

[yeps]

it wont work when i use xscale because when the body flips, the angle does too... and thats what determines weather to flip it or not...

[VENGEANCE MX]

Yeps, it looks like the arm is inside the body movie clip. That'll be causing problems.

[lesli_felix]

I think this might be a problem cause by movieclip._xmouse being relative, so when it flips, _xmouse reverses too.

Try nesting the whole thing inside another movieclip, and do your coding from there.

oop, now i understand your problem, couldnt you do
body._xscale = body.arm._xscale;
?
then flip your arm, or do the coding vice versa
all you have to do is flip them both simeutaneously
this code ensures that the body's xscale is equal to that of the arm, and thus is pointing in the correct direction

[mr_malee]

yeah, your coordinates are getting messed up when you flip on the _xscale, use the _root._xmouse instead of _root.guy._xmouse

so:

_root.guy._xscale = _root._xmouse < _root.guy._x ? 100 : -100

[yeps]

woah there mr malee, can you explain that code for me? i've seen one like it before but im not sure what it means

and then also... should i be determining whether to flip it or not by the angle? or should it maybe be the xmouse?

[mr_malee]

its a simple conditional statement, just like writing

if(_root._xmouse < _root.guy._x){

_root.guy._xscale = 100

}else{

_root.guy._xscale = -100

}

this is what i changed, i also removed the two frames from the guy.

onClipEvent (enterFrame) {

        _root.guy._xscale = _root._xmouse < _root.guy._x ? 100 : -100;

	if (angle2<-79) {
		this._yscale = -100
		_root.guy.gotoAndStop(2)
	} else{
		this._yscale = 100
		_root.guy.gotoAndStop(1)
	}
	angle2 = Math.round(angle/Math.PI*180);
	angle = Math.atan2(opp, adj);
	opp = ((_root.guy._ymouse-this._y));
	adj = -1*(_root.guy._xmouse-this._x);
	this._rotation = -1*angle2;
}

[trogdor458]

yes but it's hard to learn new forms of writing immediately
the first thing i saw was a statement, not a conditional
which confused me a bit, but then i made sense of it, seems like such a strange way to write
