yeah, i know the low res camera making things invisible would come up, thats kinda my point though, it'd be like simulated eyesight ability, it would also make distance checks on enemies uneeded, because at a certain distance they just get too small also you wouldnt have to check every pixel, just those in the middle of the screen, you could simulate the poorness of the peripheral vision by doing less frequent checks on the edges of the screens.

Like i said, not something I'd put into practice yet, just wonder if its something in the future that might be viable, i think it could even work now, but not really be worth the overhead yet.
