java.lang.Object

net.minecraftforge.fml.common.Loader

public class Loader
extends java.lang.Object

The loader class performs the actual loading of the mod code from disk.

There are several LoaderStates to mod loading, triggered in two different stages from the FML handler code's hooks into the minecraft code.

1. LOADING. Scanning the filesystem for mod containers to load (zips, jars, directories), adding them to the modClassLoader Scanning, the loaded containers for mod classes to load and registering them appropriately.
2. PREINIT. The mod classes are configured, they are sorted into a load order, and instances of the mods are constructed.
3. INIT. The mod instances are initialized. For BaseMod mods, this involves calling the load method.
4. POSTINIT. The mod instances are post initialized. For BaseMod mods this involves calling the modsLoaded method.
5. UP. The Loader is complete
6. ERRORED. The loader encountered an error during the LOADING phase and dropped to this state instead. It will not complete loading from this state, but it attempts to continue loading before abandoning and giving a fatal error.

Phase 1 code triggers the LOADING and PREINIT states. Phase 2 code triggers the INIT and POSTINIT states.

Method Detail

instance

public static Loader instance()

injectData

public static void injectData(java.lang.Object... data)

getModList

public java.util.List<ModContainer> getModList()

loadMods

public void loadMods()

Called from the hook to start mod loading. We trigger the identifyMods() and Constructing, Preinitalization, and Initalization phases here. Finally, the mod list is frozen completely and is consider immutable from then on.

preinitializeMods

public void preinitializeMods()

isModLoaded

public static boolean isModLoaded(java.lang.String modname)

Query if we know of a mod named modname

Parameters:

modname -

Returns:

If the mod is loaded
