Lua hooks needed!

[Taugeshtu]

Trying to fill the wiki, run into problems with new hooks. I look into Bindings.cpp:

Code:

cPluginManager
    constant E_PLUGIN_CHUNK_GENERATED,                cPluginManager::E_PLUGIN_CHUNK_GENERATED
    constant E_PLUGIN_CHUNK_GENERATING,                cPluginManager::E_PLUGIN_CHUNK_GENERATING
    constant E_PLUGIN_BLOCK_TO_DROPS,                cPluginManager::E_PLUGIN_BLOCK_TO_DROPS

Everything is fine.
Now:

Code:

cPlugin
    function OnChunkGenerated                        Plugin_OnChunkGenerated00

And that's it. No OnChunkGenerating, no OnBlockToDrops. Am I missing something, or there's something wrong?
Could someone explain, please?

And, well, since it's about hooks, can someone explain how server behaves when OnCollectItem hook returns true and false?
