Hello

I need an example script or a solution for map buildings works in multiplayer.
I have tried my own script but it does not work.

When the button is pressed by the server:
server:
new object: table: 0C2F57A0
write object: table: 0C2F57A0
write networkGetObjectId: nil

client:
Lua: Error running function: packetReceived
<path>/ExtraFile.lua(98) : attempt to index field 'object' (a nil value)

When the button is pressed by the client:
client:
new object: table: 02BA8080
write object: table: 02BA8080
write networkGetObjectId: nil

server:
Lua: Error running function: packetReceived
<path>/ExtraFile.lua(98) : attempt to index field 'object' (a nil value)

SampleMapBuilding = {};

function onCreate(self, id) --trigger callback: ModfilenameWithoutExtension.onCreate
print("created sample Mapbuilding, id: ", id);
SampleMapBuilding:load(id)
end;

function SampleMapBuilding:load(id)

self.transform = id;
self.showText = "";

self.isActive = true;

end;

function SampleMapBuilding:loadMap(name)
end;

function SampleMapBuilding:deleteMap()
end;

function SampleMapBuilding:mouseEvent(posX, posY, isDown, isUp, button)

g_currentMission:addExtraPrintText("ShowText from Client");

return self;
end;

function NetworkEvent:new(object)
local self = NetworkEvent:emptyNew()
self.object = object;
print("new object: ", tostring(self.object))
return self;
end;

function NetworkEvent:readStream(streamId, connection)
local id = streamReadInt32(streamId)
self.object = networkGetObject(id);
self.object.showText = streamReadString(streamId);

print("read networkGetObjectId:", tostring(id))
print("read object:", tostring(self.object))


if not connection:getIsServer() then
g_server:broadcastEvent(NetworkEvent:new(self.object), nil, connection, self.object);

The problem is that your class is not an "Object" and thus networkGetObjectId is not working

http://www.ls-mode.de has the trigger script online now as well. There you can find some examples how to derive from Object and register new Network Objects with a onCreate function.

I can recommend to study for example TipTrigger:
