Minecraft 21w13a
This snapshot adds goats, a darker splash screen, axolotl spawns, and the light block!
These writeups assume you have read the Official Changelog before continuing.
Table of Contents
Goats
Goats have 10 health and take 10 less fall damage than other mobs.
Spawning
Goats spawn with a weight of 10, twice as much as llamas, and in groups of 4-6, the same as llamas.
Spawned goats have a 2% chance to be a screaming goat and swap out their normal sounds for screaming sounds. A screaming goat cannot become a normal goat and vice-versa.
Speed
Goats have a movement speed of 0.2, the same as other passive mobs such as cows. Goats get 25% extra speed when following or tempted and double their speed when panicking (when you hit them).
Jumping
Goats will search for a block to jump to in a 11×11×11 cube centered on the goat. When the jump behavior is triggered, every tick, the goat will pick a random block in that cube. The blocks are weighted by distance squared, so, a goat is four times as likely to pick a 10 block jump rather than a 5 block jump.
When the goat tries a potential jumping location, it checks:
- If it can pathfind there normally by walking 7 blocks
- If it will collide with blocks on the way
- If the jump velocity exceeds 1.5 blocks/tick
If any of these conditions are satisfied, the goat will not use that jump. Goats will try up to 20 times (and spend up to 20 ticks) looking for a jump.
Once a goat finds a jump, it prepares for 40 ticks (2 seconds) before jumping. Then, it sets a 600-1200 tick cooldown (30-60 seconds, uniform random, both ends inclusive) between the next jump. This cooldown is also set when the goat spawns.
If a goat is moved to a different block at any time while searching for or preparing a jump, the jump will be cancelled, and will have to wait half the usual cooldown for another jump.
Goats will not try to jump if they are standing on a honey block.
Underwater Mob Spawns
Glow Squids and Axolotls now count towards the underground_water_creature mob cap instead of the old water creature cap. Both caps hold 5 mobs in singleplayer. They spawn in packs of 4-6 anywhere below sea level (y=63) and below the ocean if in an ocean biome. The bottom of the ocean is determined when the world first generates, placing blocks won’t change the spawning location.
Note: Underwater mob spawns are bugged in 21w13a. This was fixed in 21w16a.
Freeze Damage
Mobs in the freeze_hurts_extra_types entity tag (Striders, Blazes, Magma Cubes) will take 5 times more damage from freezing. The time it takes to get frozen does not change.
