Hey guys

Here's the scenario:

I have a grid (203*203), and this grid is stored in an array map(x,y). If a block is placed, the array will return a 1, otherwise a 0 is returned (for example, there is a red block at 87,4, then map(87,4)=1). The player objects are those circles. How would I go about checking if the circles are in direct line of site or not?

Thanks,

TheComet

Following a ray connecting two circles, you check the array's content. If there is at least one block which is a wall, there are not in sight, very simple.

Or you know the theoretics but not the technique to do it?
