Changeset 1564 for code/trunk/src/orxonox/objects/SpaceShipAI.cc

Timestamp:

Message:

• several small changes in most of the HUD classes (code cleanup): removed obsolete variables, privatized all member variables, removed resizing functioncalls from tick, destroying overlayelements, added some const qualifiers.
• moved calculation functions for RadarObject-position to Math.h and changed the phi/right/radius format to Vector2. the functions are used too by SpaceShipAI.
• cycleNavigationFocus takes the nearest object if focus was NULL
• BarOverlayElement works in both directions (left to right and right to left)
• fixed bug causing SpaceShipAI to not stop shooting when losing target - this also speeds up orxonox a lot, because there are less projectiles

…or the BarOverlayElement will look strange
