Make Sure Function is There Before Calling in Module?

[inoobe_xi]

I have multiple modules, all with the same name, but some have a function called updateModel and others don’t. When I call the updateModel function in a module that doesn’t have the function I get an error. I was wondering if there was a way to check if the function is there before calling it.

Script that errors:

if tile:FindFirstChildOfClass("Model") and tile:FindFirstChildOfClass("Model"):FindFirstChild("Visuals") then
	local mod = require(tile:FindFirstChildOfClass("Model").Visuals)
	
	mod.updateModel() --This is the line that is causing the error.
end

Modules are tables. You can check if the updateModel value of the module is nil

If module.updateModel then
    module.updateModel()
end

You could also ensure its a function since that would call updateModel if it were anything but nil

If module.updateModel and type(module.updateModel) == 'function' then
    module.updateModel()
end

Perhaps you could try:

if mod.updateModel then
    mod.updateModel()
end

Edit: Thanks to @Fm_Trick for the reminder that there shouldn’t be a () in the condition.
