Since World of Warcraft runs Lua 5.1, I'd like to know if there is a way to get what I need without using the goto
operator. This is my code: this code reads the contents of a tooltip line by line, as if it were a text file
-- _G["UniScan_wpnTooltipTextLeft"..n]:GetText() return the text at n line
local line, n = nil, 1
while (_G["UniScan_wpnTooltipTextLeft"..n]:GetText()) do ::redo:: --As long as there are lines of text
if string.find("Durability", _G["UniScan_wpnTooltipTextLeft"..n]:GetText()) then
line = n - 1
break
end
n = n + 1
end
if not line then goto redo end
If, due to a UI loading bug, at the end of the loop the line variable is equal to nil
, just repeat 开发者_运维问答the loop so the line variable has a finite value. How can I achieve this in Lua 5.1?
How about:
while ((not line) or _G["UniScan_wpnTooltipTextLeft"..n]:GetText()) do
...
