Texture Coordinates problem.

I'm trying to display a progress bar made with a texture file in a frame. The goal is to set the width of this texture according to a given parameter: let's say from 0 (no visible texture) to 1 (texture fills all the frame's width). At 0.5, the left side of the bar must be filled with the texture.

At this time, I have:

Lua Code:

myFrame.texture:SetTexture(pathToMyTGAfile)
        myFrame.texture:SetTexCoord(0, 0.5, 1, 0.5)
        myFrame.texture:SetAlpha(1)

Whatever the values of SetTexCoord(), the texture fills all the frame's width. :(
The bar size is 100 (w) x 15 (h) px. The TGA file is 8 (w) x 16 (h) px.

I know it would be easier to create a child frame inside the "bar" frame, fill it with texture and then set the width of the child frame, but in my case, it will lead to others problem. So I would prefer to manage the texture coordinates... If it is possible.

Thank you.

SetTexCoord sets a subsection of the texture file to show as the texture like the minimap pips are all in one file and they pull each pip out by its coordinates.

perhaps a statusbar would work better. You could use your texture for the fill, have a background or not, set colors, have it mouse interactable or not... and more

something like this

lua Code:

local statusbar = CreateFrame("StatusBar", nil, UIParent)
statusbar:SetPoint("CENTER", UIParent, "CENTER", 0, -250)
statusbar:SetStatusBarTexture("Path to your texture file")
statusbar:GetStatusBarTexture():SetHorizTile(false)
statusbar:GetStatusBarTexture():SetVertTile(false)
statusbar:SetStatusBarColor(0, 1, 0)
 
statusbar:SetMinMaxValues(0, 100) -- 0 - 100 bar
statusbar:SetValue(50) -- half full

Though initially I didn't want to create another frame/object, your solution is fine (just added SetSize()).
Thank you Billtopia :)
