Detecting proper framebuffers

[Ertain]

Thanks, man, I've been meaning to rewrite that function.

Why not patching the love API with a internal error catching ?
Something like :

Code: Select all

if not love.graphics.newFramebufferOriginal then
  love.graphics.newFramebufferOriginal = love.graphics.newFramebuffer
  love.graphics.newFramebuffer = function(...)
    local ok, ret = pcall(love.graphics.newFramebufferOriginal(...))
    if ok then
      return ret
    end
    return nil
  end
end

Remember! pcall operates like this:

Code: Select all

pcall(func, args, ...)

not

Code: Select all

pcall(func(args, ...))

It could also be more cleanly done like:

Code: Select all

local original = love.graphics.newFramebuffer

function love.graphics.newFramebuffer(...)
  local ok, ret = pcall(original, ...)
  return ok and ret or nil
end

I actually had a library that wrapped functions (and even tables) with a single command.. I think it was on the old wiki though..

Showoff.

But really, how did that work? *is interested*

Probably something like this:

Code: Select all

function pwrap(func)
    return function(...)
        local ret = {pcall(func, ...)}
        local ok = table.remove(ret, 1)
        if not ok then return nil, ret[1] end
        return unpack(ret)
    end
end

-- call it like so:
love.graphics.newFramebuffer = pwrap(love.graphics.newFramebuffer)
