Behaviour components the client draws with

A Bedrock entity is defined twice: a behaviour pack entity (minecraft:entity) holds its server-side components, and a resource pack client entity (minecraft:client_entity) holds how it is drawn. Observed · the vanilla packs of bedrock-samples v1.26.60.5 Some components of the behaviour entity change the drawing: its size, its colour and the textures it is drawn with. Components live either in the entity’s components or in component_groups that its events add and remove, so the value an entity has depends on its state (adult or baby, tame or wild). Observed · the 128 vanilla behaviour entity files of bedrock-samples v1.26.60.5

Size: minecraft:scale

minecraft:scale (value) sizes the entity, and the client entity’s own scripts.scale multiplies it. Inferred 47 of the 128 vanilla behaviour entities carry it, in their components or in groups. Observed · the 128 vanilla behaviour entity files of bedrock-samples v1.26.60.5 Examples Observed · the 128 vanilla behaviour entity files of bedrock-samples v1.26.60.5:

Entity	Where	Value
cat	group minecraft:cat_adult	0.8
cat	group minecraft:cat_baby	0.4
chicken	group minecraft:chicken_baby	0.5
fox	group minecraft:fox_baby	0.5
pufferfish	components	1.2
salmon	groups scale_small, scale_normal, scale_large	0.5, 1, 1.5

The cat’s geometry is therefore drawn at 0.8 of its modelled size as an adult and 0.4 as a kitten. Inferred

Colour: minecraft:color

minecraft:color (value, a dye index) is the entity’s colour, and it becomes the change colour (CHANGE_COLOR) that the entity’s colour-mask materials tint by when its render controller gives no color; see entity materials. Inferred Four vanilla behaviour entities carry it Observed · the 128 vanilla behaviour entity files of bedrock-samples v1.26.60.5:

Entity	Where	Value	Confidence
cat	group minecraft:cat_tame only	14 (red)	Observed
wolf	group minecraft:on_tame_collar_color	14 (red)	Observed
sheep	one group per wool colour (minecraft:sheep_white 0, minecraft:sheep_black 15, …)	the wool’s dye	Observed
tropical fish	groups per pattern colour, with minecraft:color2 for the second colour	dye indices	Observed

A wild cat has no minecraft:color, so its change colour is white and its colour-mask material leaves its texture as it is. Inferred

Texture choice: variant, mark_variant and skin_id

minecraft:variant, minecraft:mark_variant and minecraft:skin_id (each a value) are numbers that the client reads as query.variant, query.mark_variant and query.skin_id, and render controllers index their texture arrays by them. Inferred · from the vanilla render controllers indexing arrays by these queries Each is set by a component group, so the number stands for a state the behaviour pack keeps by group name. Observed[the vanilla villager_v2 behaviour file of bedrock-samples v1.26.60.5] The villager’s Observed · the villager_v2 behaviour file of bedrock-samples v1.26.60.5:

Component	Groups and values
minecraft:variant (profession)	unskilled 0, farmer 1, fisherman 2, shepherd 3, fletcher 4, librarian 5, cartographer 6, cleric 7, armorer 8, weaponsmith 9, toolsmith 10, butcher 11, leatherworker 12, mason 13, nitwit 14
minecraft:mark_variant (biome clothes)	desert_villager 1, jungle_villager 2, savanna_villager 3, snow_villager 4, swamp_villager 5, taiga_villager 6; plains has no group and keeps 0
minecraft:skin_id	villager_skin_0 to villager_skin_5, 0 to 5

The render controllers’ arrays list the professions and biomes in the same order, plains first among the biomes. Observed · the villager_v2 render controllers of bedrock-samples v1.26.60.5 A villager spawned, born or spawned with a village gets one of the six skin groups at random, each with weight 1 (minecraft:entity_spawned, minecraft:entity_born, minecraft:spawn_from_village). Observed[the villager_v2 behaviour file of bedrock-samples v1.26.60.5] One cured from a zombie villager keeps that zombie’s skin, tested by is_skin_id, and one converted from the old villager entity draws a new one (minecraft:entity_transformed). Observed[the villager_v2 behaviour file of bedrock-samples v1.26.60.5] The six skins all name the same texture, textures/entity/villager2/villager, so the skin chosen changes nothing in the vanilla pack.
