Properties

The properties are a way to customize the behavior of your world when loaded. To use them, you need to create an instance of SlimePropertyMap and add the properties you want to apply to the world.
See the example below:

// create a new and empty property map
SlimePropertyMap properties = new SlimePropertyMap();

properties.setValue(SlimeProperties.DIFFICULTY, "normal");
properties.setValue(SlimeProperties.SPAWN_X, 123);
properties.setValue(SlimeProperties.SPAWN_Y, 112);
properties.setValue(SlimeProperties.SPAWN_Z, 170);
properties.setValue(SlimeProperties.ALLOW_ANIMALS, false);
properties.setValue(SlimeProperties.ALLOW_MONSTERS, false);
properties.setValue(SlimeProperties.DRAGON_BATTLE, false);
properties.setValue(SlimeProperties.PVP, false);
properties.setValue(SlimeProperties.ENVIRONMENT, "normal");
properties.setValue(SlimeProperties.WORLD_TYPE, "DEFAULT");
properties.setValue(SlimeProperties.DEFAULT_BIOME, "minecraft:plains");
// add as many as you would like

After you have created the property map, don't forget to pass it to the readWorld method when loading the world.
See the Loading Worlds page for more information on how to read and load worlds.
