  1. POReason why my loop to find an object in an Array only works for the first time?
    text
    copied!<p>I am creating a program that displays several bases and the amount of troops each base has. There are two types of bases, friendly and enemy bases. Each Base extends GCompound and consists of a GRect and a GLabel(to display the number of troops). Two arrays are used to keep track of the bases, one for friendly, one for enemy.</p> <p>I want the user to be able to press the mouse down on one friendly base and release on a different friendly base, causing the troop amount to be transferred from the first base to the second one. </p> <p>My problem currently is I am only able to detect the base the user presses the mouse down on, and not the base that the mouse is released on. I am using the method getElementAt from the ACM library to return the GObject that a mouse action takes place on.</p> <p>Code for the mouse press: </p> <pre><code>public void mousePressed(MouseEvent e){ int mouseX = e.getX(); int mouseY = e.getY(); for(int i = 0; i &lt; PlayerBaseArray.length; i++){ if(getClickedObject(mouseX, mouseY) == PlayerBaseArray[i]){ //Checks to see if the clicked base is in the Array of friendly bases. pressedIndex = i; pressedBaseTroopCount = PlayerBaseArray[pressedIndex].getTroopCount(); } } } </code></pre> <p>Code for the mouse release:</p> <pre><code>public void mouseReleased(MouseEvent m){ int mouseX = m.getX(); int mouseY = m.getY(); for(int i = 0; i &lt; PlayerBaseArray.length; i++){ if(getClickedObject(mouseX, mouseY) == PlayerBaseArray[i]){ // This is always false for some reason. PlayerBaseArray[i].changeTroopCount(pressedBaseTroopCount); PlayerBaseArray[pressedIndex].changeTroopCount(-pressedBaseTroopCount); } } } </code></pre> <p>Method to see what object is clicked:</p> <pre><code> private GObject getClickedObject(int x, int y){ GObject clicked = getElementAt(x, y); if(clicked == null) return null; else return clicked; } </code></pre> <p>For some reason the if statement in <code>mouseReleased()</code> is never true, even though it works properly in <code>mousePressed()</code>. Any idea on why the if statement in <code>mouseReleased()</code> does not work?</p> <p>I've tried researching the problem to no avail, and instead of wasting another night on it I thought I would ask here. Thanks!</p>
