<function name="Call" parent="hook" type="libraryfunc"> <description> Calls all hooks associated with the given event until one returns something other than `nil`, and then returns that data. In almost all cases, you should use <page>hook.Run</page> instead - it calls hook.Call internally but supplies the gamemode table by itself, making your code neater. </description> <realm>Shared and Menu</realm> <file line="62-L125">lua/includes/modules/hook.lua</file> <file line="74-L137">lua/includes/modules/hook.lua</file> <args> <arg name="eventName" type="string">The event to call hooks for.</arg> <arg name="gamemodeTable" type="table">If the gamemode is specified, the gamemode hook within will be called, otherwise not.</arg> <arg name="args" type="vararg">The arguments to be passed to the hooks.</arg> </args> <rets> <ret name="" type="vararg">Return data from called hooks. Limited to **6** return values.</ret> </rets> </function> <example> <description>Runs function `DoSomething`, which eventually calls the event `DoneDoingSomething`, triggering the hooked function `DoSomethingElse`.</description> <code> local function DoSomething() -- Does something hook.Call( "DoneDoingSomething" ) end local function DoSomethingElse() -- Does something else, once the hook "DoneDoingSomething" is called. print( "Done!" ) end hook.Add( "DoneDoingSomething", "Does something else", DoSomethingElse ) DoSomething() </code> <output> ``` Done! ``` </output> </example> <example> <description>You can also make custom functions controllable via hooks.</description> <code> local function MakeCheese() local shouldMakeCheese = hook.Call( "MakeCheezPleez" ) if shouldMakeCheese then print( "yay" ) else print( "nay" ) end end local function MakeCheeseOrNot() return player.GetCount() >= 1 end hook.Add( "MakeCheezPleez", "Does something else", MakeCheeseOrNot ) MakeCheese() </code> <output>If there is players in the server, we print `yay`. If there isn't, we print `nay`.</output> </example> <example> <description>Calls the event `DoneDoingSomething` with some arguments.</description> <code> hook.Add( "DoneDoingSomething", "Does something else", function( a, b ) print( a ) print( b ) end ) hook.Call( "DoneDoingSomething", nil, "Hello", "Hey" ) </code> <output> ``` Hello Hey ``` </output> </example>
