Processing / How to make selectable object, that moves where i click
<p>that really sucks ... i know how to make classes, objects, interfaces, loops etc . But everytime i try to make a unit or more than one, that is moving (when i select it) to the point where i click i get errors, errors and errors .... Why the hell theres nowhere a tutorial for that ? </p>

<p>My new class looks so atm : </p>

<pre><code>class Unit {

    int X;
    int Y;
    int Breite;
    int Laenge;
    int ID;
    boolean ausgewaelht = false;

    Unit() {
    }

    Unit(int x, int y, int breite, int laenge) {
    }

    void create(UnitContent function) {
        function.form();
    }

    void move(float geschwindigkeit) {
        if(isTriggerd(X,Y,Breite,Laenge) == true){
            X = X+(int)geschwindigkeit;
            if(X &gt; width) {
                X = 0;
            }
        }
    }  

    void setXandY(int x , int y) {
        X = x;
        Y = y;
    } 

    void setBreiteandLaenge(int breite, int laenge) {
        Breite = breite;
        Laenge = laenge;
    }  

    void setID(int id) {
        ID = id;
    }  

    int getX() {
        return X;
    }

    int getY() {
        return Y;
    } 

    int getBreite() {
        return Breite;
    }

    int getLaenge() {
        return Laenge;
    }    

    int getID() {
        return ID;
    }  

    boolean isTriggerd(int x, int y, int breite, int laenge) {
        if(mouseX &gt; x &amp;&amp; mouseX &lt; x+breite &amp;&amp; mouseY &gt; y &amp;&amp; mouseY &lt; y+laenge ) {
            return true;
        }
       else {
            return false; 
       }
   }
}
