How do I pass a modules function in parameter functionToBind in ContextActionService:BindAction()

[metatablesnow (snow)]

Hello!

The title really explains it all, but if you’re still confused, I’ll try go into more detail:
I want to be able to do something like this,

function randomModuleScript:BindInputs()
    contextActionService:BindAction("SomeRandomName", self:SomeRandomFunction, ...)
end

but when I put self:SomeOtherFunction as a parameter it errors (as it should).
Is there a workaround this / is there a way to do this?

I still haven’t found an optimal workaround for this

The issue here stems from the fact that when you pass self:SomeRandomFunction as a parameter, you are not correctly binding the function with its context (self). Instead, you need to bind the function to the module’s context explicitly. Below is a step-by-step solution:

1. Store the Function Reference: Ensure that the function reference is stored correctly. You can use a local function within the module to bind the function correctly.

2. Use an Anonymous Function: Use an anonymous function with the correct context to pass to BindAction.

Here’s an example solution:

local randomModuleScript = {}

-- Define your function within the module
function randomModuleScript:SomeRandomFunction(actionName, inputState, inputObject)
    print("Function called with action:", actionName)
    -- Your function code here
end

-- Function to bind inputs
function randomModuleScript:BindInputs()
    local contextActionService = game:GetService("ContextActionService")
    
    -- Bind the action with an anonymous function to maintain context
    contextActionService:BindAction("SomeRandomName", function(actionName, inputState, inputObject)
        self:SomeRandomFunction(actionName, inputState, inputObject)
    end, false, Enum.KeyCode.E) -- Example key binding, adjust as necessary
end

return randomModuleScript

why

1. Defining the Function:

   • SomeRandomFunction is defined within the module.

2. Binding the Function:

   • In BindInputs, ContextActionService:BindAction is used.
   • Instead of directly passing self:SomeRandomFunction, an anonymous function is used to wrap the call to self:SomeRandomFunction.
   • This anonymous function maintains the correct self context when SomeRandomFunction is called.

Usage:

When you want to use this module, you simply call BindInputs on an instance of the module:

local myModule = require(path.to.randomModuleScript)
myModule:BindInputs()
