Walkable spheres?

[Sanity_ba]

Is it possible to make a sphere that you can walk all the way around? I've been trying to make a very small earth for my friend but I cant get it to work :hmph:.

 

[Ennui]

Hmm. That's interesting, but i doubt it's possible. If it is it might take some coding for that to work, since HL2's levels aren't based off of spherical gravity like earth, just there is up and down.

It could be possible if you took the center of the globe and made it the center of gravity. And the out side of the globe gridded. So in an essense your making the individual pieces in a some what enlongated piramid. To where the base of the piramid is the actually the ground. Then place a sky box sphere which is hollow that your little world would sit in. With gravity effected to as you would not need it! Kinda like 0 gravity. Mainly take a cube and try it with a cube inside of a cube first to see if its even possible!

I have been wanting a map built like it for a long time but I am no mapper. But would love to damn sure try it!

how do you make something the center of gravity? I dont think hammer can do that, which is what I said before. I know HOW to do it, but you can't without extra coding.

 

[Sanity_ba]

Alpha can you go into a bit more detail? I didn't understand much of that... ;(

 

[Llama]

nice idea but i dont think it would be useful

 

[Sanity_ba]

It would to me and my friend...

 

[Llama]

woah, sorry. Didnt mean any offense....

 

[Sanity_ba]

None taken, I didn't mean it like that.

Do you know any good XSI moddeling tuturials for modelling ppl? Im shit at it

 

[azz0r]

Could you not make the globe a vehicle entity and make the viewpoint the top?

 

[Sanity_ba]

I couldn't get that to work ;(.

there's a decent one on the verc i believe.

hmm... gravity............ i would ask the people at hull breach, they have variable grav stuff. Google.

But yah, that would be interesting.... I wonder, does source treat magnets with variable strengths at different differences, or just "X strength when its not touching" and "Y strength when it is" ? IF it allows for different magnetic attractions at different distances, then you could treat players like magnets and have a magnet in a hollow sphere that the players would walk on.

But then u get into the problems of perspective, again, look at hull breach, they coded some neat stuff to allow for zero G 360 perspectives in source. They might help. But Source does not allow ( i tink ) for a player to stand in any direction other than perpendicular to the ground. So you cant lean over. You never see live players upsidown. You would have to code for that. (HULL BREACH) .

So its possible, but not without some changing of hard coded physics and perspective stuff.

BUT another way around it would be to do a treadmill like sphere, that would work. Have a player stand on top of it, and player not move on sphere, but sphere moves around under player. Gives full illusion of walking on a globe, but without the evil bad physics part of walking upsidedown. You could do that on a massive scale, but only with 1 player, and that player would have to be the center of the universe.

So ur answer, you can do it for singleplayer, but not in multyplayer. So it can be done easy for single, hard as hell and full mod for multyplayer.

 

[Ennui]

I don't think that making it move like a treadmill for the player would be anything remotely close to "easy".

 

[Hazar]

another question relevant to the thread is if the sphere were hollow, could you walk inside it?

(all the way around)

 

[Kaine904]

ooo... one word, hamster ball. That would probably be the most effective way of doing something like this..... i wonder.... can u make a glass sphere and put a person inside of it? Spawn the guy in it?

Hmmm... One might just be able to map that....

With the difficulties of gravity aside you wouldn't be able to make it large enough to feel right. Even if you made a globe as large as the grid in hammer it would still have extreme curvature. The entire level would feel like one continuous hill instead of flat land as we know it.

About the hamster ball thing, you could make that pretty easily by making a model and tying it to a prop_physics.

 

[Pesmerga]

It's very possible. It just requires some extensive coding that repositions the player's character model and camera and match it up with the angle of the brush he's currently on. Jumping would just have to be re-coded to jump in a vertical motion paralell to the camera angle, or vertically lined up with the character model. Relativity is the basic concept behind it.

 

[Sanity_ba]

I think I'll give it up as it did only start out as a small project for a friend and I don't want to spend a huge amount of time on it.

But then u get into the problems of perspective, again, look at hull breach, they coded some neat stuff to allow for zero G 360 perspectives in source.

How do you know they´ve already achieved this?

i dont think they're talkign about making a whole planet, but rather a superhigh gravity object, like a neutron star with some kinda sphere built around it.


If you wanted to make a whole planet you'd be better off just linking a whole bunch of flat maps together in such a way that the world "wraps around"
