font color from tooltip

Mazzop · 03-21-13, 04:37 AM

So i would like to know font color from a given tooltip line
cant find anything useful in lua documentation for that

And if its possible, that color would be same for all or could be changed by some addons already?

If the text is colored using inline color codes:

Code:

-- turns "|cffff0000" into 255, 0, 0 for example
local r, g, b = GameTooltipTextLeft1:GetText():match("|cff(%x%x)(%x%x)(%x%x)")
r, g, b = tonumber(r, 16), tonumber(g, 16), tonumber(b, 16)

If it's colored using the SetTextColor API:

Code:

local r, g, b = GameTooltipTextLeft1:GetTextColor()

Thanks, maybe i dont need compare strings and can get all i want from color

When the text is using inline color codes, GetTextColor will still return the default color (usually white), so you still need to use string matching to determine whether there are inline color codes overriding the deafult color.

some things i dont get here
basically i want scan dropped item and know if they are thunderforged, elite etc.
that info is in 2nd tooltip line, so knowing that line is green (if item is normal, there is item level in that line written in different color) is better than comparing strings from all languages.

but when i do print(GameTooltipTextLeft2:GetText()) its coming in white, but still got green from GameTooltipTextLeft2:GetTextColor(), well greenish, gets me g 0.99999779462814
when doing it with itemLevel line, print "pass" correct color

well, i wrote something and need wait for debug till wednesday probably

SetTextColor only affects the individual font string object it's called on. The text and the color are not intriniscally connected, so if you take the text from that font string object, and display it on another font string object, or pass it to a function -- like print() -- you only get the text, not the color or alignment or size or any other properties of the original font string object.

If you got a color when print()-ing the item level line, that means that the item level line uses inline color codes (eg. "|cffffd000Item Level: 496|r") which override the text color set on the font object.

Also, based on what you described, you will need to use string matching on the actual text content, as that green text can be "Heroic" -- or it can be "Raid Finder", or it could be something else. Fortunately, you don't need to do any of the work translating the string; you can just use the pre-defined Blizzard global strings. For example:

Code:

if GameTooltipTextLeft2:GetText() == ITEM_HEROIC then
    -- text is "Heroic" in an English client, "Heroisch" in a German client, etc.
end

Finally, the values returned by GetTextColor can be a bit odd. If you need to match them to detect something, you can "fix" them via rounding to the nearest 100th, like so:

Code:

local r, g, b = GameTooltipTextLeft2:GetTextColor()
r = floor(r * 100 + 0.5) / 100
g = floor(g * 100 + 0.5) / 100
g = floor(b * 100 + 0.5) / 100
