Changeset 10023 for code/branches/modularships/src/orxonox/worldentities

Timestamp:

Apr 9, 2014, 9:50:45 PM (11 years ago)

Author:

Message:

ShipParts can "die" and detach the corresponding Entity while doing so. Issue: The Entity being detached while a hit on a collisionshape is being handled causes a runtime-error.
