Moving right along, I have another problem that is so complicated in its
nature that I am not sure I can even adequately explain it. I am planning a
realtime RPG (unlike my past couple projects where I just sort of dove into
them without planning out the "engine" or anything).
Its going to be made with flat, overhead pictures (well, hopefully at a
slight angle to give some illusion of 3D).
The problem comes in with trying to figure out sight. I need to be able
to set some pixels to black because you can't see them. I don't want simply
to place a black square on every block you can't see (its going to be made
of blocks, I haven't yet decided how big, but you move in pixel ammounts,
not from block to block). For every opaque object I could determine the
angle from you to its top and you to its bottom. That would give me an
angle range to shade out, but I have no idea how. I attached a small
This does bring up a bunch of problems. Even if I could make all the
pixels black in that angle range, I bet it would slow the computer down a
bunch. I might just end up finding the angle from you to every block on the
screen and blacking out the ones that are past opaque objects. Basically
the same as I was hoping to do, except that it would do it by block instead
of by pixel.
Thanks for reading and thinking about this! ANY suggestions would be
of course, the easy route would be to simply ignore sight, which I also
