hi

there are functions in clientside(fr_client.lua) e.g server.setPedAnimation

where is server defined?how does it even work?

[pa3ck]

fr_client.lua @ line 8:

server = createServerCallInterface() 

util.lua @ line 1:

function createServerCallInterface() 
    return setmetatable( 
        {}, 
        { 
            __index = function(t, k) 
                t[k] = function(...) triggerServerEvent('onServerCall', g_Me, k, ...) end 
                return t[k] 
            end 
        } 
    ) 
end 

It`s advanced stuff, not easy to understand if you never used metatable before.
