CallHook

I've found how to use CallHook from any plugins.

Code:

function PLUGIN:checkPlugins(player)
    local arr = util.TableToArray( { player } )
    util.ConvertAndSetOnArray(arr, 0, player, UnityEngine.Object._type)
    local thereturn = plugins.CallHook("canRedeemKit", arr )
    if(thereturn == nil) then
        return true
    end
    return false, tostring(thereturn)
end

basically we could use the old way and do something like: arenaplugin:canRedeemKit(player)
but the advantage of this is that if you want to make another plugin (another arena plugin, or block a player from using stuff, or what ever) you will NOT have to edit the original plugin.
you just have to add inside your new plugin:
function PLUGIN:canRedeemKit(player)
return "You can't redeem the kit
end
to block the kit from being redeemed.
[DOUBLEPOST=1417026836][/DOUBLEPOST]using 2 arguments will not work
local success, err = plugins.CallHook("watchEver", are)
as the CallHook may only send back 1 argument (the first one, so for success only, err will ALWAYS be nil)

 

I really like the idea of letting other plugin cancel actions.

The only problem I see is if 2 plugins "awnser" to the same callhook, only one awnser will be received. I don't think it's a big deal as the action will be cancelled anyway.

 

yes exactly.
if both plugins don't return anything => then it will continue
if both plugins say that it can't continue => it will not continue
if 1 plugin out of the 2 say that it can't continue => it will not continue
so yeah it's exactly the thing that i was looking for
