is there a way to use the ‘tertiary operator’ to shorten this code?  
[AS]if (this.\_x\<0) {  
this.\_x = Width;  
}  
if (this.\_x\>Width) {  
this.\_x = 0;  
}  
if (this.\_y\<0) {  
this.\_y = Heigth;  
}  
if (this.\_y\>Heigth) {  
this.\_y = 0;  
}[/AS]  
i tried  
AS?this.\_x = Width;  
(this.\_x\>Width)?this.\_x = 0;  
(this.\_y\<0)?this.\_y = Heigth;  
(this.\_y\>Heigth)?this.\_y = 0;[/AS]  
but an error comes up…

can anyone help?

never mind, i figured it out, you need a : null at the end of the statement for the else. so it would be:

AS ? this.\_x = Width : null;  
(this.\_x\>Width) ? this.\_x = 0 : null;  
(this.\_y\<0) ? this.\_y = Heigth : null;  
(this.\_y\>Heigth) ? this.\_y = 0 : null;[/AS]  
or to shorten it:

AS ? this.\_x = Width : (this.\_x\>Width) ? this.\_x = 0 : (this.\_y\<0) ? this.\_y = Heigth : (this.\_y\>Heigth) ? this.\_y = 0 : null;[/AS]

actually, the last script is not a really good idea… :-\

you should use this one instead. 😉

```auto
this._x<0 ? this._x=Width : this._x>Width ? this._x=0 : null;
this._y<0 ? this._y=Heigth : this._y>Heigth ? this._y=0 : null;

```

I think you’re kinda missing the poin of the operator 😉

```auto

this._x = (this._x < 0) ? Width : (this._x > Width) ? 0 : this._x;
this._y = (this._y < 0) ? Height : (this._y > Heigth) ? 0 : this._y;

```
