Every User Callback in Lua Scripts.

The Lua scripts are executed by functions called User Callbacks. Some of these functions are called by the Unity Engine, and some other are called by Massive Loop. The User callbacks are referred as Message in API documentations. Each component might introduce a series of messages, but all these messages called in you Lua script.

Here are the list of all available User Callbacks implemented in Massive loop.

• Called by Script

OnEnable: Called before the start, after initial pass, or after disable object enabled back on.

Start: In this phase, the start function in your code will be called.

FixedUpdate: Fixed update may called multiple time per frame. This sub loop often called physics loop, which makes Fixed Update useful for physics calculation.

Update: The update function gets called on every frame.

LateUpdate: Called latest on the frame.

OnDisabled: Called when the object becomes disabled.

• Called by Collider

OnTriggerEnter

OnTriggerExit

OnTriggerStay

• Called by Rigidbody

OnCollisionEnter

OnCollisionExit

OnCollisionStay

• called by Animator

OnAnimatorIK

OnAnimatorMove

• Called by Particle System

OnParticleCollision

• Called by Renderer

OnBecameVisible

OnBecameInvisible

• Called By MLSynchronizer

OnOwnerChanged

OnBecomeOwner

OnLostOwnership

Note: The Animator callback may called on both physics loop and game logic.

You may define a function for any of these tasks. You don't have to define a function for any of these callbacks. Use the script variable from LUA.script to define a function for these callbacks.

do
       
    local MyScript = LUA.script; 
    
    function MyScript.OnEnable()
       -- OnEnable callback
    end
    
    function MyScript.Start()
    	-- Start callback. 
	end
    
    function MyScript.FixedUpdate()
        -- fixed update
    end
    
    -- @param other: Collider
    function MyScript.OnTriggerEnter(other)
    	-- On Trigger Enter
    end
    
    -- @param other: Collider
    function MyScript.OnTriggerExit(other)
        -- On trigger Exit 
    end
    
    -- @param other: Collider
    function MyScript.OnTriggerStay(other)
        -- On trigger stay
    end
    
    -- @param other: Collision
    function MyScript.OnCollisionEnter(other)
        -- On Collision enter
    end
    
    -- @param other: Collision
    function MyScript.OnCollisionExit(other)
        -- On Collision exit
    end
    
    -- @param other: Collision
    function MyScript.OnCollisionStay(other)
        -- On collision stay
    end
    
    -- @param gameObject: GameObject
    function MyScript.OnParticleCollision(gameObject)
        -- On Particle collision 
    end
    
    function MyScript.Update()
        -- Update 
    end
    
    function MyScript.OnAnimatorMove()
       -- On Animator Move 
    end
    
    --@param layerIndex: number
    function MyScript.OnAnimatorIK(layerIndex)
       -- On Animator IK 
    end
    
    function MyScript.LateUpdate()
        -- Late Update
    end    
    
    -- @param newOwner: MLPlayer
    function MyScript.OnOwnerChanged(newOwner)
        -- On Owner changed 
    end
    
    function MyScript.OnBecomeOwner()
        -- On become owner 
    end
    
    function MyScript.OnLostOwnership()
        -- On Lost ownership 
    end
    
    function MyScript.OnBecameVisible()
        -- On Became visible 
    end
    
    function MyScript.OnBecameInvisible()
        -- On became invisible 
    end
    
    function MyScript.OnDisable()
        -- On Disable
    end
    
end
