Z64 Lua Hooks

This project provides an environment to create hooks and mods for Ocarina of Time 1.0 and Majora's Mask US.

All you need is the Bizhawk emulator and the ROM.

No setup is required. It works right out of the box.

####Features:

• Read/write address support by id. Ex: Addr.getById("Amount.Bomb").set(10)
• Actor RAM map. Ex: Actor.new(pointerToBomb).x.set(10)
• Actor Finder. Ex: Actor.getActorsByType(CST.ACTOR_TYPE.Bomb)[1].timer.set(11)
• Enum. Ex: CST.ACTOR_TYPE.Bomb == 0x0010
• Modular Mod support. Ex: See /Mods folder.
• Event support. Ex: Utils.onButtonPress Utils.setTimeout

####How to use:

• Open Bizhawk and load the ROM.
• Open the Lua Console via Tools->Lua Console
• Open the script main.lua
• Click to checkbox to apply the mods you want.
• NOTICE: Always close the Mod Window before closing the Lua Console.

####How to contribute:

• Extend the Actor RAM map in Actor.lua.
• Add Enums in Cst.lua.
• Add new addresses in Addr.wch via Tools->RAM Watch
  • Dungeon map/key/compass/flags.
  • Permanent flags.
• Create new mods following examples in /Mods.
• Check TODO.txt

####Mods made so far:

• Control Any Actors
• Minimap Displaying All Actors
• Attracts all Actors towards Link
• Scale Link and Actors
• Display Actor Data
• Teleport
• Change Name
• Bomb Tornado (Causes bombs to loop in circles around you)
• Display Bomb (Display all bombs x,y,z,timer and address)
• Press L to levitate
• Teleport
• Change Tunic Hex Color (Modifies ROM)

instance
	void set(number value)
	number get()
	string toString()

static 
	Addr getById(string id)

######Mod

constructor(string id,string name,Function onActivate,[Function onDeactivate])

instance
	void activate()
	void deactivate()

static 
	Mod getById(string id)
	void activate(string id)
	void deactivate(string id)
	void openMainForm()

######Actor
