Game development

This information is meant to help newcomers learn how to develop their own games for the Spring Engine.

General

• Development Tools
• Game structure
  
• Game specification
  
• Simple Game Tutorial - a bit old and confusing
• Free Assets
• The Complete Guide To Making A Spring Game - this one is the best so far

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

• Differences of .lua and .cob unit scripts

Lua Animations

To edit .lua files you need a text editor.

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

COB Animations

The binary '.cob' file format is obsolete and some '.cob' files might be copyrighed by cavedog. A '.cob' file can be decompiled to see what it is doing or if you have the source, that is a '.bos' file, you can compile it into a '.cob' file.

To edit .bos files you need a program/compiler. The most famous one is Scriptor

• 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.
