Wormholes, sometimes broken - r.364

[oO]

To reproduce
- wait outside station
- follow the first ship that exits it
- in a while that ship will create a wormhole
- try to enter the wormhole
- if it was the only AI ship around the wormhole will work, if there are another AI ships around the wormhole won't work and the other AI ships will try to get inside the wormhole, sometimes getting "stuck" to it somehow.

version: svn://svn.berlios.de/oolite-linux/trunk rev. 364
Addons: behemouth, deposed, eagle2, impcourier, pirate coves, supercobra, thargoidwars.


EDIT: hmm doesn't seem reproducible without addons, will do more testing

EDIT2: only could reproduce it 3 times... out of a lot of tries, i don't know what could be the problem.

[oO]

I noticed this bug today again:

I went through a wormhole and nothing happened, 2 other AIs (escorts to the wormhole opener) got stuck to the wormhole like flies into sticking paper. And then after a while they got sucked into it, and i could use it too... weird

Couldn't find a way to reproduce it

EDIT: ah yes i could reproduce this twice (but tried more times, so it's not sure), i had enabled a pair of NSLogs when this happened and disabled the random selection of worlds as you can see in the svn diff:

Code: Select all

The other NSLog at performHyperSpaceExit:

When the 2 escorts were comming, i paused and hit "0", the result was:

Can anyone tell me what the "mass" means in the entity dump?
