local heroes = {
		["Archer"] = {Damage = 2},
		["Fire Wizard"] = {Damage = 5},
		["Builder"] = {Heal = 25},
		["Gunner"] = {Damage = 1},
	}

I want to the the name in this table like, “Damage” or “Heal”.
I want to get it from using a string.
heroes[name][string]

Hey there!

To get the value of “Damage” or “Heal” from the table using a string, you can simply use the square bracket notation with the string as the key. For example, if the variable name contains the name of the hero you want to access and string contains either “Damage” or “Heal”, you can retrieve the corresponding value like this:

local value = heroes[name][string]

If string contains “Damage” and name contains “Archer”, for example, the value of value will be 2. Similarly, if string contains “Heal” and name contains “Builder”, the value of value will be 25

You can do this assuming you want to know whether the heroes heal or damage:

local str = nil
for i, v in pairs (heroes[name]) do
    str = i
end
print(str)

It will print either “Damage” or “Heal”

If it worked please set it as solution so other people can see it :slight_smile:

Generally you would use a for loop for this purpose as assigning the index to a variable doesnt give you the name of the index, It more of gives you to Value of that said index, so ifd I did this:\

Tab = {
    ["indexKey"] = "value"
}

print(Tab["indexKey"]) --> value

IT would Return the value rather than the index, with the usage of for loops, you can 2 Arguments (or whatever they are called.

The First is index which is name of the index holding the value
The Second is value which is the Instance, number, or boolean it contains.

So with this, you can do a simple search of the table using this for loop to get their names.

for index, value in Tab do
    -- index is the name of the key
    -- value is the value of the index
end

He already knows this but what he wants is to know whether the hero heals or do damage.

local heroes = {
		["Archer"] = {Damage = 2},
		["Fire Wizard"] = {Damage = 5},
		["Builder"] = {Heal = 25},
		["Gunner"] = {Damage = 1},
	}
	
	for i,v in pairs(heroes[name]) do
		print(i)
	end

does not work.

Replace the variable name with the name of the hero

Nvm, I did something wrong. Let me do a little more testing.

9 
local heroes = {
		["Archer"] = {Damage = 2},
		["Fire Wizard"] = {Damage = 5},
		["Builder"] = {Heal = 25},
		["Gunner"] = {Damage = 1},
	}
	
	for i,v in pairs(heroes[name]) do
		print(i)
	end

The reason that the code does not work is that name is not defined in the code you provided. Without the definition of name , heroes[name] would not refer to any key in the heroes table, and the for loop would not iterate over any values

You need to define the name variable before using it in the loop. For example, if you want to iterate over the keys and values of the “Archer” entry in the heroes table, you can modify the code as follows

local heroes = {
    ["Archer"] = {Damage = 2},
    ["Fire Wizard"] = {Damage = 5},
    ["Builder"] = {Heal = 25},
    ["Gunner"] = {Damage = 1},
}

local name = "Archer" -- define the name variable

for i,v in pairs(heroes[name]) do
    print(i, v) --> Damage   2
end

Thanks! I never knew the “i” would print that.

Your welcome =) feel free to message me when you need more coding help

For future reference, refer to Cairo’s reply. This will tell you the index, and value of the table you’re iterating.

If my reply helped you out, feel free to mark this as the solution! It is greatly appreciated.
