Collision strangeness

Earlier I docked at the mining base in the first system and when it was time to leave, I proceeded to turn and face the direction I wanted to go, but all of a sudden my ship started to spin violently and then it was flung at a pretty high speed. I'm assuming that while I was turning, I collided with the station which is what led to this strange bug.

first, i think there was some issues of crazy dead polygons inside the mining base that has been brought up while retexturing it. Other than that, there is (and has always been) an issue of colliding via torque rather than linear motion.

My suggestion is to not do that anymore.

fixes to that behavior are medium-ish priority, and probably wont get addressed for a few minor revs into 0.5.x

I would like to limit the maximum speed you can fly at after a collision to be bounded by some sane limit (possibly the sum of the velocities of the two ships that collided)... not sure what constitutes as a sane limit.

I have noticed a whole lot of AI ships spinning in circles with huge star streaks around them when I target them, especially since the hack that keeps AI players from taking damage when colliding.

The problem lies with how torque is allowed to progress through a collision (this is how it was explained to me) while we stop linear motion during a collision.

Damn!! My game of flying around space and purposely crashing into stations is over!!

Yeah he was encouraging that a while back

but apparently most of the collide code works as intended.

Enjoy the Choice

oh, that explains why I saw a cap ship (gleaner?) fly to a gas mining station just this morning...

Yea, eventually we'll get to fixing why AI ships cant fly ...
