I am trying to do a Java GUI game of dots and boxes, and I need to make the bounds for detecting whether or not the mouseMoved that the person made was in the bounds of the top, left, bottom, or right of a box. I refer to each box that we are in by a number that is added when the boxArray has a box added to it, and graphicall wise by the top right x,y coordinate that the box has (BX1, and BY1 for BOX X)
Now I believe I know why my problem is occuring, but have no clue how to fix it, and I was working on it for an eternity last night.
The box's bounds are decided in this format:
---------------
|\ /|
| \ / | Where this is all area in the
| \ / | top triangle for the top line, all area in
| \ / | the left triangle for the left line and so on
| \ / |
| / \ |
| / \ |
| / \ |
| / \ |
|/ \|
----------------Now if the mouse is positioned above the top triangle and within that box, then it should hi-light the possible move for the top of the box that you are currently in. And if the mouse moves over a bit, and goes over the line into the left or right triangle, then the left or right should be accessed.
The problem I am having is my code to do this, handles the cases in order, which I have no idea how else to handle them...I think I need to handle them all at once but don't know how.
Here is the code I have inside my mouseMoved method
public void mouseMoved(MouseEvent e)
{
Line currentLine;
xMousePos = e.getX();
yMousePos = e.getY();
mouseMovable = true;
int boxNum = -1;
Graphics g = getGraphics();
g.setColor(Color.gray);
orientBoxes(); //fills the boxArray with the boxes and their pos
for(int i=0; i < theBoxes.length; i++)
{
//top line
if( (xMousePos > theBoxes[i].BX1 && xMousePos < (theBoxes[i].BX1+dist) )
&& ( yMousePos >= theBoxes[i].BY1 && yMousePos < theBoxes[i].BY1+(dist/2) ) )
{
//boxNum = i;
currentLine = theBoxes[i].top;
System.out.println("The coordinates of bx and by are: [" + theBoxes[i].BX1 +
", " + theBoxes[i].BY1 + "]");
currentLine.isTop = true;
System.out.println("You are in the top sector of box: " + theBoxes[i].boxNumber);
break;
}
//left line
else if( (yMousePos > theBoxes[i].BY1 && yMousePos < (theBoxes[i].BY1+dist) )
&& xMousePos < theBoxes[i].BX1+(dist/2) )
{
//boxNum = i;
currentLine = theBoxes[i].left;
System.out.println("The coordinates of bx and by are: [" + theBoxes[i].BX1 +
", " + theBoxes[i].BY1 + "]");
currentLine.isLeft = true;
System.out.println("You are in the left sector of box: " + theBoxes[i].boxNumber);
break;
}
//bottom line
else if( (xMousePos > theBoxes[i].BX1 && xMousePos < (theBoxes[i].BX1+dist-20) )
&& yMousePos >= theBoxes[i].BY1+(dist/2)
&& yMousePos <= theBoxes[i].BY1+dist )
{
//boxNum = i;
currentLine = theBoxes[i].bottom;
System.out.println("The coordinates of bx and by are: [" + theBoxes[i].BX1 +
", " + theBoxes[i].BY1 + "]");
currentLine.isBottom = true;
System.out.println("You are in the bottom sector of box: " + theBoxes[i].boxNumber);
break;
}
//right line
else if( (yMousePos > theBoxes[i].BY1 && yMousePos < (theBoxes[i].BY1+dist) )
&& xMousePos >= theBoxes[i].BX1+(dist/2)
&& xMousePos <= theBoxes[i].BX1+dist)
{
//boxNum = i;
currentLine = theBoxes[i].right;
System.out.println("The coordinates of bx and by are: [" + theBoxes[i].BX1 +
", " + theBoxes[i].BY1 + "]");
currentLine.isRight = true;
System.out.println("You are in the right sector of box: " + theBoxes[i].boxNumber);
break;
}
}
}Keeping in mind, that right now I am not actually drawing anything, just trying to verify im in the right bounds when I am. Currently what I have will say I'm in the top, when I want to be in the right, or in the bottom when I want left...There is overlap that isn't being accounted for and I have no idea how to make it happen. Please help this poor old fool!!
