Changeset 8426 for code/branches/bigships/src/orxonox/worldentities

Timestamp:

May 9, 2011, 2:59:07 PM (14 years ago)

Author:

Message:

• Moved handling of blur effect from Engine.cc to SpaceShip.cc.
• Implemented handling of multiple engines per SpaceShip, so that in future it would be possible to turn single engines on/off individually (for example if one gets destroyed on a big ship).
• Updated some pointers accessing the single Engine of a SpaceShip to ask the SpaceShip itself instead for data.
