Changeset 6404 for code/branches/presentation2/data

Timestamp:

Dec 23, 2009, 7:44:49 PM (14 years ago)

Author:

Message:

Simplified our resource system a bit by working with a single resource group on the user end.
However you can still declare resource groups for separate loading. But accessing the files will always look in all groups.

Location:

code/branches/presentation2/data

Files:

• DataInstallScript.cmake (modified) (1 diff)
• DefaultResources.oxr (moved) (moved from code/branches/presentation2/data/resources.oxr)
• lua/LuaStateInit.lua (modified) (3 diffs)
