[lua] FontString help

[Vyntrox]

hey guys,

working on some infopanels for my ui. so what i have is this

local MyAvoid = 5+GetParryChance("Player")+GetDodgeChance("Player")

local MyAvoidance = CreateFrame("FRAME", nil, UIParent)
    MyAvoidance:SetPoint("CENTER", UIParent, 0, 0)
	MyAvoidance:SetWidth(200)
    MyAvoidance:SetHeight(20)
    
    local MyAvoidanceText = MyAvoidance:CreateFontString()
        MyAvoidanceText:SetPoint("CENTER")
        MyAvoidanceText:SetSize(200, 20)
        MyAvoidanceText:SetFont(cfg.font, 12, "OUTLINE")
        MyAvoidanceText:SetText("Avoidance: "..MyAvoid.."%")

my avoidance is shown correct but like 25.175693545672348%.
how can i abbreviate the fontstring that it is shown as 25.1% or 25.17%

thank you for helping me

Change

MyAvoidanceText:SetText("Avoidance: "..MyAvoid.."%")

To

MyAvoidanceText:SetFormattedText("Avoidance: %.2f%%", MyAvoid)

For 25.17%, or %.1f for 25.1%

[Treeston]

For 25.17%, or %.1f for 25.1%

<nitpick>It would be 25.18% and 25.2%</nitpick>

[Vyntrox]

For 25.17%, or %.1f for 25.1%
<nitpick>It would be 25.18% and 25.2%</nitpick>

ups! u r absolutely right treeston


but what i forgot, now i have the avoidance displayed, but it's static.
how do i have to setup the script to make it dynamic respectively wich event is fired.

MyAvoidance:RegisterEvent(...)

MyAvoidance:SetScript("OnUpdate" , function(self) ... end)

EDIT: Woops, glanced and thought you were working with health.

OnUpdate will fire on every redraw as long as your frame :IsVisible.
You'll want OnEvent with COMBAT_RATING_UPDATE

Here is how I'd do what you want:

local MyAvoidance = CreateFrame("FRAME", nil, UIParent)
MyAvoidance:SetPoint("CENTER", UIParent, 0, 0)
MyAvoidance:SetWidth(200)
MyAvoidance:SetHeight(20)
    
MyAvoidance.text = MyAvoidance:CreateFontString()
MyAvoidance.text:SetPoint("CENTER")
MyAvoidance.text:SetSize(200, 20)
MyAvoidance.text:SetFont(cfg.font, 12, "OUTLINE")

MyAvoidance:RegisterEvent("COMBAT_RATING_UPDATE")
MyAvoidance:SetScript("OnEvent",function(self)
    self.text:SetFormattedText("Avoidance: %.2f%%",5+GetParryChance("Player")+GetDodgeChance("Player"))
end)
