# If enabled, nodes won't be used up when placed.
# Note: This behavior can also be toggled in-game with the /infplace command.
#
# - true: enabled
# - false: disabled
# - auto: only enabled when Creative Mode is enabled (default)

# If enabled, new players receive some initial items when joining for the first time.

# If enabled, the game will use all mapgen aliases for the v6 mapgen.
# If disabled, it will only use a minimal set of mapgen aliases.
# If enabled, there should be biome-specific tree, leaves and ground nodes. If disabled, stuff should use fallback nodes (like stone instead of desert stone).
#
# Many mapgen aliases have fallback values when no value is provided. Having this setting disabled can be useful to test whether those fallback values are functional.
devtest_v6_mapgen_aliases (Use all v6 mapgen aliases) bool false

# If enabled, the game will use dungeon stairs by enabling the corresponding mapgen aliases.
#
# Disabling this setting can be useful to test whether dungeons still work when stairs are not defined.
devtest_dungeon_stairs (Generate dungeon stairs) bool false

# If enabled, the mapgen alias 'mapgen_mossycobble' will be used. This should enable random mossy cobblestone in dungeons.
# If disabled, it won't be used. The engine should fall back to cobble instead.
devtest_dungeon_mossycobble (Generate mossy cobblestone) bool false

# If enabled, some very basic biomes will be registered.
