Issues with Textures

[Dralie]

Hello I am trying to make a simple addon that makes a box and has it change colors based on what type of stagger you have on a brewmaster monk. I have run into an issue where the box is no longer showing up and doesnt change textures when I get it to show up.

local StaggerBox = CreateFrame("Frame",nil,UIParent)
StaggerBox:SetFrameStrata("BACKGROUND")
StaggerBox:SetWidth(64) -- Set these to whatever height/width is needed 
StaggerBox:SetHeight(64) -- for your Texture
StaggerBox:SetPoint("CENTER",-150,0)
StaggerBox:RegisterEvent("PLAYER_REGEN_DISABLED")
StaggerBox:RegisterEvent("PLAYER_REGEN_ENABLED")
StaggerBox:CreateTexture()
StaggerBox:SetAllPoints()
local function HideOrShow(self, event, ...)
    if event == "PLAYER_REGEN_DISABLED" then
        StaggerBox:Show()
    
    elseif event == "PLAYER_REGEN_ENABLED" then
        StaggerBox:Hide()
        end
end
 
StaggerBox:SetScript("OnEvent", HideOrShow)
 
 
local function DebuffCheck(self, event, ...)
    if UnitDebuff("player","Light Stagger") then
        StaggerBox:SetTexture(.5,1,0,1)
    elseif UnitDebuff("player","Medium Stagger") then
        StaggerBox:SetTexture(.5,1,0,1)
    elseif UnitDebuff("player","Heavy Stagger") then
        StaggerBox:SetTexture(1,0,01)
    end
end
 
StaggerBox:SetScript("OnEvent", DebuffCheck)

StaggerBox:SetScript("OnEvent", DebuffCheck) is overwriting your first event handler.

You either need to register the UNIT_AURA event and check your debuffs when that fires or make it an OnUpdate script since UNIT_AURA could very well fire more often than once per frame if you're in a group.

The error I get before and after the changes you suggested is showing

StaggerBox is a frame not a texture, first you need to put a texture on that frame prolly something white because you can color that nicely (texture:SetTexture("Interface\\Buttons\\White8x8.blp"), then color it with texture:SetVertexColor(r, g, b).

[Resike]

Something like that:

local StaggerBoxFrame = CreateFrame("Frame", nil, UIParent)
StaggerBoxFrame:SetFrameStrata("Background")
StaggerBoxFrame:SetWidth(64)
StaggerBoxFrame:SetHeight(64)
StaggerBoxFrame:SetPoint("CENTER", - 150, 0)
StaggerBoxFrame:RegisterEvent("PLAYER_REGEN_DISABLED")
StaggerBoxFrame:RegisterEvent("PLAYER_REGEN_ENABLED")
StaggerBoxFrame:RegisterEvent("UNIT_AURA")
 
local StaggerBox = StaggerBoxFrame:CreateTexture(nil, "Background")
StaggerBox:SetTexture("Interface\\Buttons\\White8x8.blp")
StaggerBox:SetDrawLayer("Background", 0)
StaggerBox:SetAllPoints(StaggerBoxFrame)
 
local function OnEvent(self, event, ...)
    if event == "PLAYER_REGEN_DISABLED" then
        StaggerBox:Show()
    elseif event == "PLAYER_REGEN_ENABLED" then
        StaggerBox:Hide()
    elseif event == "UNIT_AURA" then
        local unit = ...
        if unit == "player" then
            if UnitDebuff("player", "Light Stagger") then
                StaggerBox:SetVertexColor(0.5, 1, 0, 1)
            elseif UnitDebuff("player", "Medium Stagger") then
                StaggerBox:SetVertexColor(0.5, 1, 0, 1)
            elseif UnitDebuff("player", "Heavy Stagger") then
                StaggerBox:SetVertexColor(1, 0, 0, 1)
            end
        end
    end
end
 
StaggerBoxFrame:SetScript("OnEvent", OnEvent)

Edit: I realized what I messed up
Thank you very much for your help!

No problem.

Just FYI, if all you want is a solid color for your texture, you don't need to give it a texture file first and call :SetVertexColor(). You can just use :SetTexture(r,g,b[,alpha])

What Seerah wrote is true but I have to say that at some point I had errors with just using SetTexture because doing this:

local tex:CreateTexture(nil,"BACKGROUND",nil,-8)
tex:SetTexture(1,0,0,0.5)

would not give me a red semi-transparent texture. It may be fixed now but I definitely had it happening.

Combining both works perfectly anytime:

local tex:CreateTexture(nil,"BACKGROUND",nil,-8)
tex:SetTexture(1,1,1)
tex:SetVertexColor(1,0,0,0.5)

When working with statusbars you can do:

local bar = CreateFrame("StatusBar",nil,UIParent)
local tex:CreateTexture()
tex:SetTexture(1,1,1)
bar:SetStatusBarTexture(tex)
bar:SetStatusBarColor(1,0,0,0.5)

Hmm i didn't know about that, but i'm pretty sure its the same thing, i can also imagine it's using the same white8x8 texture too.
