'''Dimension types''' are technical [[Minecraft:JSON]] files within a [[Minecraft:data pack]], in the folder {{cd|data/<namespace>/dimension_type}}. They define properties of a [[Minecraft:Dimension definition|dimension]] such as world height build limits, the ambient light, and more.<br />
<br />
== JSON format ==<br />
<div class="treeview"><br />
* {{nbt|compound}} The root object.<section begin="definition" /><br />
** {{nbt|double|coordinate_scale}}: The multiplier applied to coordinates when leaving the dimension. Value between 0.00001 and 30000000.0 (both inclusive).<br />
** {{nbt|boolean|has_skylight}}: Whether the dimension has skylight or not. If set to false, weather is additionally disabled.<br />
** {{nbt|boolean|has_ceiling}}: Whether the dimension has a bedrock ceiling. Note that this is only a logical ceiling. It is unrelated with whether the dimension really has a block ceiling. If set to true, there is no weather, the way respawn and mob spawning positions are calculated is changed,{{info needed|how?}} and maps record terrain within a 32 block radius around the player, instead of 64 – however, no data is actually recorded, and instead a pattern will be displayed.<br />
** {{nbt|boolean|has_ender_dragon_fight}}: Whether this dimension can have an [[Minecraft:ender dragon]] fight. {{more info|What exactly is controlled by this}}<br />
** {{nbt|float|ambient_light}}: How much light the dimension has. When set to 0, it completely follows the light level; when set to 1, there is no ambient lighting.{{more info|Precise effects for other values need testing}}<br />
** {{nbt|boolean|has_fixed_time}}: (optional, defaults to <code>false</code>) Whether this dimension has fixed time. {{more info|which behaviours are affected by this?}}<br />
** {{nbt|int|monster_spawn_block_light_limit}}: A single integer from 0 to 15. Block light level must be less than or equal to this value for monsters to spawn.<br />
** {{nbt|int}}{{nbt|compound|monster_spawn_light_level}}: An integer or int provider from 0 to 15. Each time a monster spawn is attempted, a value is calculated using this int provider. The result of the following formula must be less than or equal to this value for monsters to spawn: <code>max( skyLight - 10, blockLight )</code> during thunderstorms, and <code>max( [[Minecraft:Light#Internal_sky_light|internalSkyLight]], blockLight )</code> during other weather.<br />
*** {{nbt inherit/int provider}}<br />
** {{nbt|integer|logical_height}}: The maximum height to which [[Minecraft:chorus fruit]]s and [[Minecraft:Nether portal]]s can bring players within this dimension. This excludes portals that were already built above the limit as they still connect normally. Cannot be greater than {{nbt|integer|height}}.<br />
** {{nbt|integer|min_y}}: The minimum height in which blocks can exist within this dimension. Must be between -2032 and 2031 and be a multiple of 16 (effectively making 2016 the maximum).<br />
** {{nbt|integer|height}}: The total height in which blocks can exist within this dimension. Must be between 16 and 4064 and be a multiple of 16. The maximum building height = min_y + height - 1, which cannot be greater than 2031.<br />
** {{nbt|string|infiniburn}}: A block tag with <code>#</code>. Fires on these blocks burns infinitely.<br />
** {{nbt|string|skybox}}: (optional, defaults to <code>overworld</code>) The skybox to use. Can be {{cd|none|overworld|end}}.<br />
** {{nbt|string|cardinal_light}}: (optional, defaults to <code>default</code>) Direction of cardinal light affecting blocks. Can be {{cd|default|nether}}<br />
** {{nbt|compound|attributes}}: Map of [[Minecraft:environment attribute]]s that apply when in this dimension.<br />
** {{nbt|string|default_clock}}: {{json ref|world clock}} to use as the default for this dimension. This clock will be used as default for the {{cmd|time}} command, and the <code>minecraft:wake_up_from_sleep</code> and <code>minecraft:roll_village_siege</code> [[Minecraft:time marker]]s of this clock will be used. If not specified, the dimension doesn't have a default clock.<br />
** {{nbt|string}}{{nbt|list|timelines}}: {{json ref|timeline|tag=1}} that are active in this dimension.<section end="definition" /><br />

|{{HistoryLine||1.16|dev=Pre-release 1|Added dimension types to [[Minecraft:data pack]]s.}}<br />
|{{HistoryLine||1.16.2|dev=pre1|Dimension types now use the same folder pattern in data packs as other resources: <samp>namespace/<''type''>/resource.json</samp>.}}<br />
|{{HistoryLine|||dev=pre2|Replaced the field {{nbt|bool|shrunk}} with {{nbt|double|coordinate_scale}}.}}<br />
|{{HistoryLine||1.17|dev=20w49a|Added {{nbt|integer|min_y}} and {{nbt|integer|height}}.}}<br />
|{{HistoryLine||1.18.2|dev=22w06a|infiniburn's defined tag must be preceded by a # symbol; this was previously optional.}}<br />
|{{HistoryLine||1.19|dev=22w11a|Dimension types can no longer be inlined in the dimension, they have to be a reference to a separate dimension_type file.}}<br />
|{{HistoryLine|||dev=pre1|Added {{nbt|integer|monster_spawn_block_light_limit}} and {{nbt|int}}{{nbt|compound|monster_spawn_light_level}} to the dimension type.}}<br />

|{{HistoryLine||1.21.11|dev=25w42a|Added new attributes field for dimensions to specify Environment Attributes.<br />
|Many fields have been migrated to [[Minecraft:environment attribute]]s:<br />
* {{nbt|boolean|ultrawarm}} -> {{cd|minecraft:gameplay/water_evaporates}}, {{cd|minecraft:gameplay/fast_lava}}, {{cd|visual/default_dripstone_particle}}<br />

|{{HistoryLine|||dev=25w45a|Added a new optional {{nbt|string}}{{nbt|list|timelines}} field.<br />
|The remaining functionality of {{nbt|boolean|natural}} field has been migrated to the {{cd|minecraft:gameplay/eyeblossom_open}} and {{cd|minecraft:gameplay/creaking_active}} environment attributes.<br />
|The {{nbt|string|effects}} field has been removed and replaced with the following new fields: {{nbt|string|skybox}} and {{nbt|string|cardinal_light}}.<br />
|The {{nbt|int|fixed_time}} field has been replaced by {{nbt|boolean|has_fixed_time}}.}}<br />
|{{HistoryLine||26.1|dev=snap3|Added {{nbt|string|default_clock}} field}}<br />
