at the risk of looking stupid (again)

i've done a quick simulation using an agent i've developed. the agent samples pixel colors along a series of rays and so can 'see' obstacles etc of a particular colour.

the agents are drawn with an array list to allow them to be added/removed incrementally.

problem is that at the minute an agent can only 'see' the colours of the agents after it on the array list, not those drawn before.

is there an easy way around this? i tried using pixels[] instead of 'get' but it gave an array out of bounds exception.

i've put a zip file with the simulation here:

ok, i see now, that won't work because they all need to be aware of each other during the drawing.

the only way to do it would be to do it in increments, interlacing the separate ray detecting calls.

ie where you have, in your depth ray code checking each pixel along the path in turn
 for (int x = 16; x < ray_view; x++)

you should move this up a level or two so you're effectively doing

Code:

for each pixel in path
  for each ray
    detect next pixel
    draw next pixel
 

um, not sure that will work (efficiently) because you'll be testing each ray up to 400 pixels whether they get blocked or not.
