Changeset 10631 for code/trunk/src/orxonox

Timestamp:

Oct 10, 2015, 6:38:44 PM (9 years ago)

Author:

Message:

the AI sometimes selected its own ship as target while it was steering a rocket. after destroying the rocket, the AI would then try to hit itself which led to random crashes (because of a division by zero error which was previously fixed in r10630).
this commit does not fix the root cause, but detects this case and changes the target.
