4. Flags & Properties

GWorld allows you to change world settings (flags) programmatically. These settings are stored persistently.

Set flags

You can change flags directly on the IManageableWorld object or set them during creation in the builder.

// Example: Disable PvP and change difficulty
world.setAllowPvP(false);
world.setDifficulty(Difficulty.HARD);

// IMPORTANT: Save so that it is retained after restarting! world.saveProperties();

Available settings

Here is an overview of the most important methods in IManageableWorld interface:

Category	Methods (Getter / Setter)	Description
isAllowPvP, setAllowPvP	Global PvP on/off.
Spawning	isMonsterSpawning, setMonsterSpawning	Spawning monsters.
	isAnimalSpawning, setAnimalSpawning	Spawning animals.
Environment	isWeatherCycle, setWeatherCycle		isTimeCycle, setTimeCycle	Whether the time of day is advancing.
	getTime, setTime	Current time in ticks.
Player	getGameMode, setGameMode	Default game mode of the world.
System	isLoadOnStartup, setLoadOnStartup	Should the world be loaded when the server starts?
	isKeepSpawnInMemory, setKeepSpawnInMemory	Keep spawn chunks in RAM.

Use in the Builder

When creating a world, you can also set flags generically via WorldProperty:

import en.gilljan.gworld.data.properties.WorldProperty;manager.createBuilder(„Lobby“)
    .property(WorldProperty.PVP, false)
    .property(WorldProperty.ANIMALS, false) 
    .build();
