Wierd Gravity Effects... o.0

So, I am working on my new map, fy_endersgame.(For all of you that have read the book, I am doing the battleroom... I plan to make a fy_endersgame2 wich will be an acaul model of battle school-but I need this answered first...) The map is going to be modeled in zero gravity-so I dont repeat myself, read everything after the following colon CAREFULLY: In zero g, once you jump, you jump straight and cannot alter your path until you touch a wall. Once you hit another wall, that becomes your center of gravity, so you now can jump off of this wall. Is there anyway I can imatate this is my map? I will not hesitate server commands... (of coarse-sv_gravity and so on) If this is not possible, I plan to make it to where you can swim through the level as if it was zero g (but very unrealistic zero g-notice how I listed it second?) So my problem here wich making the character is able to swim like it was zero g, the character will drown. Is there some eninity that will make the effects of the watter null? I have heard of maps that have had watter that doesnt kill... So-please help me. This is a message from a distresed map maker. ??? 8D

Put your gravity at .2, rather than 0.
It's practically the same, but I think you can then strafe while in the air.
Good luck.

I used to cheat like this for a jump map... one of those soulfatherosities, y'know that's barely uncontrollable anyway (and you cannot make it to the top when you cheat on this map)
I don't think it is possible to "bounce" on a wall, you can jump when you're on the floor, but I think that's all you can do in low gravity...

There IS an entity of that nature in the Natural Selection mod.
You can walk on walls with a func_floor.
Would be a cool asset if it were in all fgds.

Oooh, Carpenter, I'll have to check that out! Thanks... That would work the same! Kind of... o.O I feel... Motivated!

Carpenter, are you sure they use an entity for that? That pratically require almost all brushes to be tied to func_floor to make the aliens climb on them?

o.O I hate you carpenter.

[the Carpenter]

I think the NS thing works with AAA texture, rather than actually tieing the walls to that entity.

Why do you hate me, exactly, Mr. Penquin ?

Because! Its that time of the month again, Mr. Eatsfood!

Maybe if you didn't eat so much food ... you wouldn't need low gravity.
