Resetting all of Löve's callbacks?

[DaedalusYoung]

Why not do it the other way? Don't define any callbacks until the version check is passed.

Now that i think about it, you needn't do anything more complicated than this:

Code: Select all

--either the top of main.lua or love.load, shouldn't matter
-- ...
local major, minor, revision, codename = love.getVersion( )
if minor ~= 9 then error ""Using wrong löve version! Need Version 0.9" end -- also, you wanted ~= instead of !=
-- ...

Since love's default err(or)hand(ler) routine basically creates an infinite loop inside itself, acting like a "new love.run", the original will never execute any callbacks ever again, and in the new one, it only detects quit events and whether you pressed escape (to quit) or not.

Plus why would you need to nil callbacks you never created? just nil the ones you use, load, update draw, if a callback called "love.superMegaLoveCallbackNewWhichWasntInOtherVersions" exist but you dont define it then it will be nil by default, no need to make it nil again...

From what i can tell, germanunkol was worried that other existing callbacks would have been ran per-frame under the error screen, which they wouldn't have. (with the default love.errhand that is)
Since the error usually results in the program exiting, you need not nil anything anyway.

Hey, thanks for all the feedback!

Right, I forgot about the posibility to write my own error handler function. That of course solves the rest of the problems, because it won't accept any more input (I think).

Thanks!
