gravitational manipulation?

[slavatrumpevitch]

so, i have a neat idea for a mission, but i'm not sure if it's possible. I was originally going to try it with Dromed, but it simply wasn't capable of accomplishing what i wanted. i'm wondering if there's a way to change the direction of gravity, and the players orientation seamlessly, can this be done? i would also want it to affect only the player if possible. so, "down" to the player, could be the floor, or a wall, or the ceiling or whatever, and all normal movements including jumping and mantling would be possible. (rope arrows however would still always extend ropes towards the floor)

 

so, is this possible? dromed was capable of changing gravity direction, but not the player's orientation, so if gravity was inverted, the player's head would simply bash into the ceiling where he would then remain unable to move. this is exactly what i want to avoid. thanks for any advice you guys may have!

The engine is technically capable of having gravity go in any direction, and that probably could be changed at runtime. However, not every bit of code necessarily respects that setting, and thus certain subsystems may assume that gravity goes in the usual direction. Other things might simply break. Stuff like pathfinding would be an issue (AAS is normally only generated for the "ground"), I'm not sure whether the player's view would rotate, etc. The same issue you mention with Dromed might apply; I'm not sure. I've never tried it.

 

Most of these issues would be fixable with more or less effort, but as I'm sure you can appreciate it's not a high priority for us right now. This kind of stuff certainly works very well in Prey, which uses (a heavily modified version of) the D3 engine.

 

I do recall seeing some posts on doom3world.org which dealt with gravity modification. Might have some good references for anyone who wanted to take this up.

k, thanks for the advice. certainly i understand this is low priority. I wasn't asking if it was something the team would be expending time on, i was only inquiring if it was already inherently (im)possible with the engine.
