Sending Data to the Client

Garry's Mod coding

Ok so with help from people on here I made a door script, I then made a little system to get an entity’s MapID (Specifically a door) and I was wondering how to use the gotten MapID (1341) to the client so that the door text below “Door To” changes based on the MapID of the door. Here is the Code I have for my Door:


 surface.CreateFont( "OblivionDoorFont", {
    font = "Kingthings Petrock", -- Use the font-name which is shown to you by your operating system Font Viewer, not the file name
    extended = false,
    size = 30,
    weight = 2000,
    blursize = 0,
    scanlines = 0,
    antialias = true,
    underline = false,
    italic = false,
    strikeout = false,
    symbol = false,
    rotary = false,
    shadow = false,
    additive = false,
    outline = true,
} )


local doors = {
    ["func_door"] = true,
    ["prop_door_rotating"] = true,
    ["func_door_rotating"] = true,
    ["func_movelinear"] = true
}

local doorname1 = "Imperial City"

hook.Add( "HUDPaint", "DoorDisplay", function()
	local ent = LocalPlayer():GetEyeTrace().Entity
        if (not IsValid(ent) or LocalPlayer():GetPos():Distance(ent:GetPos()) > 150) then return; end

	local class = ent:GetClass()
	if (doors[class]) then
            surface.SetFont( "OblivionDoorFont" )
            surface.SetTextColor( 251, 255, 117 )
            surface.SetTextPos( (ScrW() / 1.0) - 100, ScrH() / 1.2 - -26 )
            surface.DrawText("Door to")
            surface.SetTextPos( (ScrW() / 1.1) - 35, ScrH() / 1.1 - 1 )
            surface.DrawText(doorname1)
	end
end)

And here is how I obtained the MapID of the door serverside:


 hook.Add( "PlayerSay", "PlayerSayExample", function( ply, text, team )

    if text == "/getid" then 

    local ent = Entity( 1 ):GetEyeTrace().Entity
    
    if ent:MapCreationID() == 1341 then
        print("IT ACTUALLY WORKED")
    else print("For Fuck Sake")
    end
             

        else print("Wrong Command Idiot, it's /getid you twat")
    end
   
end )

Just have a table clientside that has all the MapIDs you need: they are constant per map.

#3

With net messages :slight_smile:

If u got this ID only on server (as I understood)



if (SERVER) then
	util.AddNetworkString( "my_door_networkstring" );
	--function were do you set/get door id--
	net.Start( "my_door_networkstring" )
	net.WriteWriteEntity( door_ent )
	net.WriteWriteUInt( door_id_value, 16 ) -- I guess 16 bits might be overkill but w/e
	net.Broadcast()

else
	net.Receive( "my_door_networkstring", function(len)
		local my_door = net.ReadEntity() -- Get door entity that we will use to set ID
		local my_doors_id = net.ReadUInt(16) -- Read door's ID
		my_door.door_id = my_doors_id -- Setting that ID to door's entity so we can use it from there.
	end)

end

And then in your code



hook.Add( "HUDPaint", "DoorDisplay", function()
	local ent = LocalPlayer():GetEyeTrace().Entity
        if (not IsValid(ent) or LocalPlayer():GetPos():Distance(ent:GetPos()) > 150) then return; end

	local class = ent:GetClass()
	if (doors[class] and ent.door_id) then -- check if that door have an ID
            surface.SetFont( "OblivionDoorFont" )
            surface.SetTextColor( 251, 255, 117 )
            surface.SetTextPos( (ScrW() / 1.0) - 100, ScrH() / 1.2 - -26 )
            surface.DrawText(ent.door_id) -- Then draw it :)
            surface.SetTextPos( (ScrW() / 1.1) - 35, ScrH() / 1.1 - 1 )
            surface.DrawText(doorname1)
	end
end)

My code might be shit tho. Text me if u tried and had some issues.

But how would the table know that the MapIDs are that of an entity

Thanks I’ll give it a try, I have never touched networking as of yet

[editline]1st August 2017[/editline]

This does not seem to work or I am not knowledgeable to get it to work, here is what I have in my cl_doordisplay:





    net.Receive( "my_door_networkstring", function(len)
        local my_door = net.ReadEntity() -- Get door entity that we will use to set ID
        local my_doors_id = net.ReadUInt(16) -- Read door's ID
        my_door.door_id = my_doors_id -- Setting that ID to door's entity so we can use it from there.
    end)


surface.CreateFont( "OblivionDoorFont", {
    font = "Kingthings Petrock", -- Use the font-name which is shown to you by your operating system Font Viewer, not the file name
    extended = false,
    size = 30,
    weight = 2000,
    blursize = 0,
    scanlines = 0,
    antialias = true,
    underline = false,
    italic = false,
    strikeout = false,
    symbol = false,
    rotary = false,
    shadow = false,
    additive = false,
    outline = true,
} )


local doors = {
    ["func_door"] = true,
    ["prop_door_rotating"] = true,
    ["func_door_rotating"] = true,
    ["func_movelinear"] = true
}

local doorname1 = "Imperial City"

hook.Add( "HUDPaint", "DoorDisplay", function()
    local ent = LocalPlayer():GetEyeTrace().Entity
        if (not IsValid(ent) or LocalPlayer():GetPos():Distance(ent:GetPos()) > 150) then return; end

    local class = ent:GetClass()
    if (doors[class] and ent.door_id) then -- check if that door have an ID
            surface.SetFont( "OblivionDoorFont" )
            surface.SetTextColor( 251, 255, 117 )
            surface.SetTextPos( (ScrW() / 1.0) - 100, ScrH() / 1.2 - -26 ) )
            surface.DrawText(ent.door_id) -- Then draw it :)
            surface.SetTextPos( (ScrW() / 1.1) - 35, ScrH() / 1.1 - 1 ) )
            surface.DrawText(doorname1)
        end
    end
end)

And here is what I have in my sv_doordisplay:




hook.Add( "PlayerSay", "PlayerSayExample", function( ply, text, team )

    if text == "/getid" then 

        local ent = Entity( 1 ):GetEyeTrace().Entity
    
            if ent:MapCreationID() == 1341 then
                print("IT ACTUALLY WORKED")
                    else print("For Fuck Sake")
            end
             

        else print("Wrong Command Idiot, it's /getid you twat")
    end
   
end )

if (SERVER) then
    util.AddNetworkString( "my_door_networkstring" );
    --function were do you set/get door id--
    net.Start( "my_door_networkstring" )
    net.WriteEntity( door_ent )
    net.WriteUInt( 1341, 16 ) -- I guess 16 bits might be overkill but w/e
    net.Broadcast()
end

Pick entity id (they are constant as said previously) of that door, set your MapIDs for that door, do the same on client side - u are gucci.

It will looks something like that I guess.





local doors_ids = {
    [183] = "func_door",
    [195] = "prop_door_rotating",
    [685] = "func_door_rotating",
    [1337] = "func_movelinear"
}

local ent_index = LocalPlayer():GetEyeTrace().Entity:EntIndex() -- get Entity Index of what we are looking on

if (doors_ids[ent_index) then -- Check if that entity exist in our list
    print("cool")
end

this code is usefull (kinda), if u know already which ID of the entity will be (for map entities for example), so u can preset those and that will be much better.

If you still have any quesitons - add me.

#6

I just tried that and now the door text is not displaying…what’s your steam name or ID

#7

check ur PM xd

#8

Why not post in the thread so other people who stumble upon the thread can find the solution?

#9

Solutions is there already, I will try to help him out how to use it, I might misspell something, so I have to be sure he understand me.

All he have to do, use that command for chat to pick up entity Index, fill it in that door_ids table with names and thats done :slight_smile:

#10

I think he meant he wanted all doors to have their MapID on them, which would require networking.

#11

Nah, actually he is fine with just unique entity ID that delive server.
If someone need networking.
At the part of setting this ID, just use the code that was posted before with networkmessages, and add aditional message to players that will connect to the server, with ID’s of the doors. :slight_smile:

#12

Ok so Total Crash’s code worked all along, he helped me understand it in great depth including some extra stuff, thanks again Crash.

Marking as solved.
