Ok I am going to do it a different way.
What I would like is a shroom that spawns on certain random x coord.
I would like it to spawn levelwide, but not say between, x coords 50-100 AND NOT between xcoord 500-600.
How would I go by that?

Allowable possible x-coordinates amount to 'getWidth()-(100-50)-(600-500)' or 'getWidth()-150'.
The code above makes the proper adjustments to the coordinate value.
1 2 3 | int x = getRandomNumber(getWidth()-150);if (x > 50) x += 50;if (x > 500) x += 100; |
Thanks :).
So If i get it correctly a given Shroom will not spawn between 1200-1088, 352-282 or 896-640
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | public void add(int addAmt) { ScoreCounter+=addAmt; updateImage(); int x = (Greenfoot.getRandomNumber(getWorld().getWidth()-(1200-1088)-(352-282)-(896-640))); if (x > 1088) x += 112; if (x > 282) x += 70; if (x > 640) x += 256; int y = Greenfoot.getRandomNumber(51)+300; if(ScoreCounter == 1) { getWorld().addObject(new Shroom(), x, y); } if(ScoreCounter == 2) { getWorld().addObject(new Shroom(), x, y); } |
Lines 6 through 8 must be put in the correct order or you will inadvertently not shift when you need to. Start with the lowest coordinates and work to the highest.
So it should be
And I am guessing it works the same for Y's?
1 2 3 4 | int x = (Greenfoot.getRandomNumber(getWorld().getWidth()-(352-282)-(896-640)-(1200-1088)));if (x > 282) x += 70;if (x > 640) x += 256;if (x > 1088) x += 112; |
That should work.
To explain; if using your previously posted code, you had an x value of 780, the first step would be skipped and the latter two would be executed, adding 326 ( 112 + 256 ) to 780, making 1106, which is in an invalid range.
