Limit string length

Hi quick question!

I want to manipulate my string-length so it only shows the first numbers infront of a comma/dot.

my code looks like this
Lua Code:
  1. self.moneyText:SetText(GetMoney()/10000,10)

Very simple. But I don't know how to and I couldn't find a solution via google.

thanks^^

So you're basically just trying to show the amount of gold, not silver or copper (the 10000 division)?

couldn't you do
Lua Code:
  1. self.moneyText:SetText(math.floor(GetMoney()/10000))

thanks ! exactly what I needed. I just don't know much syntax and didn't know math.floor existed.

the 10 is the fontsize if someone wonders why I put it there.

Lua Code:
  1. self.moneyText:SetText(math.floor(GetMoney()/10000),10)

I dont think that works that way.

You would need to do
Lua Code:
  1. self.moneyText:SetFont('pathtofontfile', size, 'flags')

size is an integer, flags are all caps flags for outlines MONOCHROME OUTLINE THICKOUTLINE

I may be dead wrong, I've just always seen the way I put it done, but then again I break more stuff than I fix so take it with a grain of salt.

Yeah I forgot that the previous version was

Lua Code:
  1. GetCoinTextureString(GetMoney(),10)

Which works different

If you want to just change the size and nothing else, you can use FontString:SetTextHeight().

I've noticed another problem. The value doesn't update/doesn't change from 0 if you don't /reload

Is there a way to still make it work?

You need to register for the event that fires when you gain or lose money.

If you need help figuring out how to do that, post the rest of your code.

Makes sense,

I don't really know how though. This is the code of TinyMainbar (the Addon I used to make my panels)

The code already does what I describe, but you've broken it by moving the "how much money does the player have?" code out of the function that gets run when the event fires, so it only checks when the addon loads, but doesn't check again when the player's money changes.

Code:
-- DELETE THIS:
money = math.floor(GetMoney()/10000) .. "g"
 
local function TinyMainbarInfo_OnEvent(self, event, ...)
        if event == "PLAYER_ENTERING_WORLD" then
                -- money, durability, ilvl
                -- ADD THIS:
                local money = math.floor(GetMoney() / 10000) .. "g"
                self.moneyText:SetText(money,10)
                -- REMOVE THE ,10 ABOVE

thanks! works like a charm.

Stuff like this happens If you have no clue what you are doing. I'm going to be more careful what I change next time.
