Unit Scripting/Animations (.cob, .bos, .lua)

Unit scripts animate units and are needed for various function such as firing weapons.

• Differences of .lua and .cob unit scripts

Lua Animations

• Animation-LuaScripting
  • Animation-LuaCallins
  • Animation-LuaCallouts
  • Animation-CobLuaDifferences

COB Animations

The binary '.cob' file format is a compiled '.bos' script. To convert a '.bos' script file to '.cob' file you will need Scriptor

  • Animation-CobThreads

• Game Development:Calling basic CEGs from COB
• GPL-compliant sourcecode, scripting code examples, and other things.

Modeling

Spring supports different 3d representations: '.s3o' and '.3do'. The biggest difference between both formats is the workflow to create a new unit. There are exporter plugins for 'blender' and '3ds-max' so that texturing and modeling can be done using these. In contrast: when you model an '.3do' you have to use upspring currently.

The animation with can either be done using 'lua' or 'COB/BOS' is does not depend on either, see rigging/animation. For new units use 'lua' scripting.
