EVE General Discussion

the worst is when you have to go into structures to access a can or whatever. if it were possible to see the collision boundaries on tactical overlay that would be make life easier.

Read this.

In EVE it is up to the players to find a work around for CCP's shoddy programming.

I read it, and it doesn't say anything about object collision at all.

Why would you need chaos theory equations to predict the motion and interaction with a STATIC, STATIONARY OBJECT?

The article you linked describes event cylinders which deal with potential interactions between DYNAMIC objects in space - other ships, drones, etc. things that might change behavior between now and the next frame. Nothing at all to do with colliding with objects or why object/station collision works they way it does.

Why would the server need to "predict" the behavior of things that have no behaviors?

Doing this kind of complex analysis in order to detect collision with objects that don't move would be an enormous waste of resources and completely illogical.

So yes, I read it. Not only that, unlike you, I understood it.

…except that they're part of what ships can intersect with, and that they therefore get tossed into the same algorithms using the same models.

Because you never know where your ship might go on the next tick. You wouldn't need it if the two objects you're trying to predict are both static, but they aren't — one is moving around in according to the whims of a player. So you include them in the calculations for what the ship can collide with. What more robust: a special case for every specific type of object, or treating all objects the same using the same model?

They don't. They are trying to predict the behaviour of the ship. One of those behaviours includes colliding with other object. Other objects are things like structures, asteroids, and ships. To make things easy and consistent, they are all modelled using the same kind of collision sphere. Static objects just makes their “event cylinder” trivial to calculate, which is a good thing.

…aside from the part where it deals with how collisions work and why it's set up this way.
The ship collision calculations expect to be fed an extruded bubble. So they're being fed an extruded (length 0) bubble.

No, that was just a demo of what DX11 and tesselation can do on the client side. The client does not handle physics calculations so that won't change how you'll actually collide with stuff (only how it gets animated for the viewer's pleasure).

I believe this has been discussed and the consensus was such a system would create too much lag and might not even function properly anyways. Don't quote me on that though.


Thanks. A little bit technical though, must plea some ignorance here. Care to explain it more simply?
As from what I'm gathering, would they not be able to divide stationary objects into multiple pieces - each with it's own sphere - as to make collision detection more precise? Are they already doing this? As I noticed some objects aren't so bad, close to perfect in fact, which makes me scratch my head. It's like some structures have one giant bubble around it, others have dozens of bubbles spread around each different piece.

Years?

Ever seen the collision model used in WoW? Players walk through each other. The reason for it is seen in Battlefield: the griefing it can cause if one player stops at a doorway or window.

Realism has a place in solo games. But in MMOs with problem children they don't work at all.

It's a sci-FI game. Not science fact.

Tessellation. & DX11.
That is the video that was mentioned above. V3 is just prettiness with a bit of dynamic lighting effects & makes it easier to re-skin the same shape ( think on this last one).
Tessellation is what had the direct skin mapping for collisions.

Lol, I actually had something similar happen in my first couple weeks of playing. I was trying to warp out in low-sec but had that "bump the station" endlessly problem. It eventually pushed me THROUGH the station somehow, so I disengaged warp thinking I found a glitched out safe spot I could troll from. Well, within a few minutes someone locked onto me and showed me otherwise .
