ok 1, look expand..... i know the new version doest allow items on stairs, but how bout if u wanna know what if an item near acid and lava is actually ON lava, or if ur standing on somethingcuz the guy u just killed at point blank dropped 9+ item (so one landed under you) and u dont wanna move unless its nothing..... all this does is look at everything there, u could easily access with "L" key for "toggle expanded look mode". trust me, i think if u were "the Doom soldier" (thats what ur char is refered to by all Doom players), u would NOTICE if the preciuos Adv. Plasma Rifle was sitting on LAVA.....
2, map memory... 2 or 3 related things.
1. .... i look and see a door on the other side of the map, i move, now the door (no chance in hell i could SEE it through 15 walls) is open. hmmmm.... a little cheap maybye. wait............. forget i said anything!!!
2. ok u pull the lever, all the barrels blow up.... HOW DO I KNOW THAT WALL AT EDGE OF VEIW WAS BLOWN UP BY A BARREL ON THE OTHER SIDE??? AM I CLAIRVOYANT????
3. on that same note, when i hear a soul scream (death beyond vision), why is it, if it occurs in an area ive explored, the CORPSE APPEARS on my map.... am i PSYCHIC???
4. why cant i remember where that advanced plasma rifle was? was it on the other side of THIS lava field, or THIS one? i dont have the health to cross both ways more than once..... if i chose wrong, ill have to skip it, ARGH!......
all the map stuff has simple solution. map by memory. ie what u saw there last is what is shown. shown only includes floor tiles, bfgs and plasma rifles (give off energy that can be detected, but if u dont know its there it looks like background radiation), and door locations. doors, btw, are always remembered as closed, no matter what. u can still hear them being opened. the only way ur memory can be changed is if u pull a flood switch, in which case itll replace all apllicable tiles with water. also, computer map powerup as usual gives u a flash frame of the map, but door closed bit applys. also instead of just bfgs and plasmas u could remember all weapons, but not ammo. map powerup is exception. also this method facilitates easy use of Look-ing at known objects outside field of vision. like stairs, liquid floors (water, acid, lava), etc.
