Anyone Know the Lua for Random Numbers in ESO????

[zireko]

I have my code working pretty good the only line of code I can't find or figure out is how to get a random number to pop in.

I'm creating just a simple dice roller for my first addon. The math.random() doesn't seem to work so I even messed around with another random code but couldn't seem to plug it in either.

local Roll = 0 
 
function LootDiceRoll()
    math.random(100)
end

math.random() returns a value that you're not capturing.

How would I capture it exactly I'm currently using the tutorial code and was trying to capture it in the counter box where the counter used to be.

Your question is related more so to a programming fundamental in most languages, than to the ESO API. That is: to capture the return value of any function it is typical to assign it to a variable. Lua is no different in this regard.

Something like:

local num = math.random(100)

...would suffice to assign the return value of math.random() to the variable num, however once stored in a variable it then needs to be returned from the LootDiceRoll() function you've made.

return num

... and finally, inserted into the game UI.

Roll = LootDiceRoll()
YourXMLElement:SetText( Roll )

Good Luck!

I think I understand a little better now. But I'm getting an error. I'll go head and link my xml and lua. If you can see it I can't seem to understand where my error is at. I only get the error when I click on the area that the dice roll is supposed to occur.

XML

<GuiXml>
    <Controls>
        <TopLevelControl name="LootDice" mouseEnabled="true" movable="true">
            <Dimensions x="200" y="42" />
            <Anchor point="CENTER" />
                                  
            <OnMouseDown>
                Roll = LootDiceRoll()
                LootDice:SetText(Roll)
            </OnMouseDown>
 
            <Controls>
                <Backdrop name="$(parent)BG" inherits="ZO_ThinBackdrop" />
                <Label name="$(parent)Roll" font="ZoFontWindowTitle" color="CFDCBD" wrapMode="ELLIPSIS" verticalAlignment="CENTER" text="LootDice: ">
                    <AnchorFill />
                </Label>
            </Controls>
        </TopLevelControl>
    </Controls>
</GuiXml>

LUA

local Roll = 0 
 
function LootDiceRoll()
    local num = math.random(100)
    return num
end

and here are pictures of the addon and the error when I get it.

I think I see the issue you're having.

LootDice is not the type of element that has the :SetText() method.
Labels do however (i.e. $(parent)Roll,) so try LootDiceRoll:SetText(Roll)

Oh yeah, also... move the

            <OnMouseDown>
                Roll = LootDiceRoll()
                LootDiceRoll:SetText(Roll)
            </OnMouseDown>

to a <controls> inside <label> or just do that in the Lua

LootDiceRoll:SetHandler( "OnMouseDown", function()
    local Roll = LootDiceRoll()
    LootDiceRoll:SetText(Roll)
end)
