 |
|
Hi, im desperately trying to tile polygon shape across the whole of the
canvas but all i seem to end up with is just one line, i need to loop it so
it draw polygon across whole canvas!!!!!
if(tiled)
{
for( int y=1; y
{
for(int x=0; x<10;x++)
g.setColor(new Color(250,0,0));
g.fillPolygon(xPoints, yPoints, xPoints.length);
for(int i=0; i
xPoints[i] +=200;
}
}

Please don't SHOUT. It will not get answers sooner, and is
more likely to get your post ignored than answered.
Also, I would recommend against putting 'please help me'
in a post at all. If people will help, they will help,
it makes little or no difference if you say 'please'.

I cannot see what is wrong from your snippet, (though
if xPoints.length = 1, that might explain it) I suggest
you poast an SSCCE.

Since you are apparently new to this, I will also add..

You need to think about what needs to happen to the polygon points in order
to make them appear tiled in a grid. You are incrementing the X, but not
the Y, so the polygon stays on one line. When the X-loop ends, you need to
increment the Y values, but also to reset the X values back (relatively) to
zero or you'll end up with a diagonal.
It's also not clear to me why your outer loop (y-loop) is over the number of
points in the polygon or why it starts at 1. I would have expected
something like for (int y = 0; y < numRows; ++y) where numRows is the
number of rows to be tiled, just as you use 10 for the number of columns (0
through 9) to be tiled.

If you can use Java2D, look into transforming the coordinate system
instead of adjusting the polygon values: They should be constant
relative to some point shich you move around.
