A way to ensure hook is called last

[thegrb93]

I need my hook added with hook.Add to be called after all other hooks. Like a way to make them the lowest priority. Any ideas?

Not with the current [URL="https://github.com/garrynewman/garrysmod/blob/master/garrysmod/lua/includes/modules/hook.lua"]hook[/URL] system, it uses pairs to loop through the stored hooks so the order is undefined. ulx modifies the hook system [url]https://github.com/Nayruden/Ulysses/blob/master/ulib/lua/ulib/shared/hook.lua[/url] to add a priority argument to group hooks, I'm not sure on other admin addons.

This might work:

[lua]local oldhookfunc = GAMEMODE.PlayerDeath -- obviously replace PlayerDeath with the hook you need

function GAMEMODE:PlayerDeath(victim, inflictor, attacker, whatever)
local ret = nil
if oldhookfunc then ret = oldhookfunc(victim, inflictor, attacker, whatever) end

-- Your code here

return ret
end[/lua]

Untested, YMMV.

Hm well I can't modify the hook system myself because then it might conflict with ulx. I don't want to detour gamemode functions if I don't have to since there's no telling what problems that might cause. Lua orders it's keys by their hash value right? What if I can find a string with a high hash value.

I guess this is my solution.
[lua]
--Ensure that SF hooks are called after all other hooks.
local detour = GAMEMODE[ hookname ]
if detour then
GAMEMODE[ hookname ] = function ( self, ... )
local a, b, c, d, e, f = detour( self, ... )
if ( a != nil ) then
return a, b, c, d, e, f
else
return run( lower, customfunc, ... )
end
end
else
GAMEMODE[ hookname ] = function ( self, ... )
return run( lower, customfunc, ... )
end
end

[/lua]
