Need Help With Draggable Box - Java

Frozen™ · 12-23-2011, 07:19 PM

Hey.
I've been trying to make a box draggable, but I can't seem to get it right. Basically what I thought to do was check if the left mouse is held down, then check if the position of it is over the part I want dragged. Then it subtracts the new position of the mouse from the old position of the box, and adds that to the position of the box.

Code:

    	if(Mouse.isButtonDown(0))
    	{
    		if((x > 2 + dragAmtX) && (x < 2 + width + dragAmtX) && (y > 60 + dragAmtY) && (y < 60 + height + dragAmtY))
    		{
    		dragAmtX = 2 - x;
    		dragAmtY = 60 - y;
    		}
    	}

  //this is going to draw the box
    	drawBorderedRect(2 + dragAmtX, 60 + dragAmtY, 65 + dragAmtX, 72 + dragAmtY, 1, 0xFF3c3c3c, 0x80391BE0);

But it never works.
Help please!
