Changeset 1552 for code/trunk/src/orxonox/objects/SpaceShipAI.cc

Timestamp:

Jun 6, 2008, 5:31:58 PM (16 years ago)

Author:

Message:

several improvements:

• AI works properly now - add enemies with 'createEnemy x' where x is the number of enemies to add, default is 1. You can remove AI ships with 'killEnemies'.
• Added new explosion (with smoke)
• Added new projectile (with trail)
• Added new thruster emitter
• AI ships are destroyable - they start with 100 hp, each hit makes 15 hp damage, this value is configurable in the config-file: [Projectile] damage_
• Added AI ship spawn and explosion effects
