I'm trying to make a game where there's a map of the world and you can move units from one territory to another [key word in this sentence; trying]. To do this I need to know when the mouse is over a certain territory, i have exactly 75 territories. I think I'm fairly good at DarkBASIC, but I'm really having some difficulties with this one. Question 1: is there an easy way to do this that I simply overlooked? *optimism* Question 2: is there anyway to do this? Question 3: should I simply give up the project and try doing it in another language? Any help is uber appreciated. Thanks!

There are 10 types of people in this world. Those who know binary and those who don't.

hmm, if you find a perfect pixel collision, you could make a sprite be were ever the mouse is, and then if it hits the terretory, have your actions...

If this "territory" of yours is square, you can try checking for clicks in the area from the top-left to the bottom-right ( mx > x1, < x2; my > y1, < y2 ).

If you need to know more, you'll have to be much more descriptive.

It's positively packed with awesome.

A simple but very effective way is to have a very nice map that people are seeing (screen 0). Then have hidden bitmap with all the countries colored. Then use the point command to find the colors that correspond to that countries color code.

You can make this routine much faster by putting the hidden bitmap into a memblock and finding it there.
