Changeset 1608 for code/trunk/src/orxonox

Timestamp:

Jun 17, 2008, 3:33:03 PM (17 years ago)

Author:

Message:

• added a backlight to all SpaceShips, leaving a trail behind (configurable)
• changed some lines in SpaceShipAI, AI seems to be more fair now…
• fixed a bug in Math.cc algorithms to calculate radar positions and AI movement (division by zero and acos of 1.000001)
• added destroy() and destroydelay to ParticleSpawner, so the smoketrail of a destroyed enemy stays visible for some seconds
• added 2 lines to Orxonox.cc to make the length of the backlight-trail independend of the gamespeed
