How to use math operations from type object?

Help and Feedback Scripting Support
#1

How would I achieve a math operation from a type object? I want to be able to boost the damage dependent on it’s dmgboost.

type CombatProperties = {
	iframes: boolean,
	damage: integer,
	dmgboost: integer
}

--Properties
function combatSystem:Create(): CombatProperties
	return {
		iframes = false,
		damage = 1,
        dmgboost = 1
	}
end

How would I multiply the damage by the dmgboost? This is a module script.

#2

You’d have to set it after you called the function

#3

Could I have an example? Doing something like

combatSystem.damage = combatSystem.damage * combatSystem.dmgboost

Would just throw an error.

#4

What’s the error message in the output?

#5 
attempt to perform arithmetic (mul) on nil

As well as

Requested module experienced an error while loading
#6

Do you have ‘integer’ defined as a type? It’s not an actual type in Roblox

#7

And as a follow up, when I tried to recreate the code, it worked without any issues, assuming this was the correct setup for it.

--ModuleScript
local CombatSystem = {}

type CombatProperties = {
	iframes: boolean,
	damage: integer,
	dmgboost: integer
}

function CombatSystem:Create() : CombatProperties
	return {
		iframes = false,
		damage = 1,
		dmgboost = 2
	}
end

return CombatSystem

--Test script I used
local x = require(script.Parent);
local y = x:Create();

y.damage *= y.dmgboost;
#8

I’m trying to make it work in a way in which if the dmgboost is something like 2, it multiples it by the damage throughout multiple scripts. I might be doing something incorrect here.

#9

Can you show me the script that threw an error?

#10

I figured out the problem, but nonetheless still have another problem with making it global

#11

I’d just make another property called “baseDamage” or something like that to keep track of what it originally was.
