The map manager is a resource included in the MTA DM server suite. It offers commands, functions and events for the gamemodes to dynamically manage their maps. For example, when a race server needs to load different tracks for each race, instead of having all of them in the same resource as the main script, they can be stored in separate resources and then loaded simply with the "changeGamemodeMap" function when a new race starts.

Specifically, the map manager lists gamemodes/maps and manages gamemode/map loading. It applies certain map settings affecting the game world and sets ASE game type and map name rule values as well. It includes a web listing which autoupdates and highglights the current mode/map combination.

Las instrucciones simples

En esta sección vamos a seguir gamemode básico que creamos en el Introduction a Scripting. Añadiremos un recurso de mapa simple que sólo contiene los datos spawnpoint para los jugadores, y la carga los datos en su mayoría la escritura cuando el jugador tiene que desovar.

Ante todo, hacemos una carpeta bajo / su MTA Server/mods/deathmatch/resources/, y lo llamamos "mimapa". Entonces bajo el directorio/mimapa/, cree un archivo de texto y llámelo "meta.xml", que requieren para cada recurso.
Entre en los códigos siguientes en el archivo "meta.xml":
   <info type="map" gamemodes="miservidor"/>
   <map src=""/>         

Nota que este recurso es "unido" para el recurso principal con el " gamemodes = "miservidor", " la etiqueta, que contiene el nombre del recurso principal. En la etiqueta "de mapa", esto indica el nombre del archivo .map que contiene los datos de mapa reales.

Ahora vaya a crear otro archivo de texto bajo/mimapa/y llamarlo "", y entrar en los códigos siguientes:

   <spawnpoint id="spawnpoint1" posX="1959.5487060547" posY="-1714.4613037109" posZ="18" rot="63.350006103516" model="0"/>

Nota que "spawnpoint" es el tipo del elemento, usado en getElementsByType la función; de la misma manera, "id" es usado en getElementByID la función.

Para cargar los datos de mapa, la escritura principal necesita el acceso al recurso de mapa sí mismo. Ahora vaya a corregir el archivo script.lua en el recurso "miservidor". Entre en el código siguiente
function loadMap(startedMap)
	mapRoot = getResourceRootElement(startedMap)

addEventHandler("onGamemodeMapStart", getRootElement(), loadMap)

Basically, the "onGamemodeMapStart" event gives us the handle of the map ("startedMap"), which we used to extract the handle of the resource containing the map ("mapRoot").

With the resource handle, we can extract the spawnpoint information from it. Look at the joinHandler() function in script.lua, instead of specifying x, y and z, we can use the map data as the following:

function joinHandler()
	local spawn = getElementsByType("spawnpoint", mapRoot)
	local x,y,z,r
	for key, value in pairs(spawn) do
		x = getElementData(value, "posX")
		y = getElementData(value, "posY")
		z = getElementData(value, "posZ")
		r = getElementData(value, "rot")
	spawnPlayer(source, x, y, z)
	fadeCamera(source, true)

Now you may start the gamemode in the server console with the following command:

gamemode myserver mymap


To use the map manager, your resources must first be marked as either gamemodes or maps.

You have to tag the gamemode resource with the correct type in its info tag:

<info description="A gamemode" type="gamemode" />

Map resources also need the type="map" tag, plus a gamemodes tag listing the gamemode resources they're compatible with in a comma-separated list without spaces.

<info description="A gamemode map" type="map" gamemodes="ctv,koth" />

There can be only one gamemode and one gamemode map loaded at once.

Optional resource attributes

These attributes all go in the corresponding resource's info tag.

name: A friendly name for your gamemode or map, to be displayed in the start messages or map listings instead of the filename.


changemap newmap [newgamemode] (changes the gamemode map to a new one, optionally changing the gamemode as well)

changemode newgamemode [newmap] (changes to a new gamemode, optionally starting a map with it)

gamemode newgamemode [newmap] (same as previous one)

stopmode (stops the current mode and mode map)

stopmap (stops the current mode map)

maps [gamemode] (lists all maps in the server, optionally all maps compatible with a gamemode)

gamemodes (lists all gamemodes)


*mapmanager.color [hex color string] (changes the mapmanager's output messages' color) (default: #E1AA5A)

*mapmanager.messages [boolean] (whether map/gm changes are enabled) (default: true)

*mapmanager.ASE [boolean] (whether the manager will set ASE gametype / mapname) (default: true)

Exported functions

bool changeGamemode ( resource newGamemode, [ resource mapToLoadWith ] )

Changes the gamemode to a new one, optionally specifying an initial map for it (will load without a map by default).

bool changeGamemodeMap ( resource newMap, [ resource gamemodeToChangeTo ] )

Changes the GM map to a new one, optionally specifying a gamemode to change to before loading it (will load with the current gamemode by default).

table getGamemodes ( )

Returns a table of all gamemode resource pointers.

table getGamemodesCompatibleWithMap ( resource theMap )

Returns a table of compatible gamemode resource pointers.

table getMaps ( )

Returns a table of all map resource pointers.

table getMapsCompatibleWithGamemode ( [ resource theGamemode ] )

Returns a table of compatible map resource pointers. If the gamemode is left blank, it returns all maps which aren't compatible with any gamemode.

resource getRunningGamemode ( )

Returns the currently running gamemode's resource pointer.

resource getRunningGamemodeMap ( )

Returns the currently running GM map's resource pointer.

bool isGamemode ( resource theGamemode )

Determines if a resource is a gamemode or not.

bool isGamemodeCompatibleWithMap ( resource theGamemode, resource theMap )

Determines if a gamemode is compatible with a map or not.

bool isMap ( resource theMap )

Determines if a resource is a map or not.

bool isMapCompatibleWithGamemode ( resource theMap, resource theGamemode )

Determines if a map is compatible with a gamemode or not.

bool stopGamemode ( )

Stops the current gamemode and its map.

bool stopGamemodeMap ( )

Stop the current GM map. Determines if a map is compatible with a gamemode or not.

Fired events

(For all these events, "source" is the resource's root element.)

onGamemodeStart ( resource startedGamemode )

Fired before a gamemode starts.

onGamemodeStop ( resource stoppedGamemode )

Fired before a gamemode is stopped.

onGamemodeMapStart ( resource startedMap )

Fired before a GM map starts.

onGamemodeMapStop ( resource stoppedMap )

Fired before a GM map is stopped.

Supported map settings

The following settings from the registry are applied by the map manager when a map is started:
gamespeed [number]: The map's game speed.
gravity [number]: The map's gravity.
time [string of the form hh:mm]: The map's time.
weather [number]: The map's weather ID.
waveheight [number]: The map's wave height.
locked_time [boolean]: Whether the set time will be frozen by the manager or not.
minplayers [number]: The required minimum number of players to start the map.
maxplayers [number]: The allowed maximum number of players to start the map.
