Trivia
- Sieges can occur on mushroom islands, despite zombies not spawning on mushroom islands naturally.

Mechanics
At midnight each night (18000 in Minecraft time), there is a 10% chance that a zombie siege will be attempted that night. If a siege is to occur, attempts will be made each tick Nearly all video games (including Minecraft) are driven by one big program loop. Just as every gear in a clock is synchronized with the pendulum, every task involved in advancing a game simulation is synchronized to start the siege until either a siege is successfully started, or the sun rises. Specifically, the siege attempt is abandoned when the sky light level Light (or lighting) in Minecraft affects visibility, mob spawning, and plant growth.

can allow siege start attempts to continue well past dawn, since it reduces the sky light level.
Siege start checks
Each village has a center (defined as the geometric center of all the village`s doors) and a size (either 32 or the euclidean distance of the farthest door from the center, whichever is greater). For each player The Player Health points 20 () Armor points Varies Attack strength Fist: 1 () Items: Varies Size Height: 1.8 Blocks Width: 0.6 Blocks While sneaking: Height: 1.65 Blocks Width: 0.6 Blocks While gliding: Height: 0.6 
, the village with the center nearest to that player is a candidate for a siege when the player is less than the village`s size + 1 blocks away from the center (by euclidean distance). In other words, the player must essentially be within the village for a siege to be considered.

, or the village has not been "stable" (no doors added or removed) for at least 20 ticks (1 second), the next player`s village is considered.
Ten attempts are made to choose a random siege starting point on a circle with a radius 0.9 times that of the village`s size centered upon a village that is not within the bounds of any other village.

of the chosen point is that of the center of the village. If all ten attempts fail, the entire siege attempt fails, but another siege may be attempted on the next game tick.
If a valid siege starting point is found, a location is chosen (as described below) as if to spawn one zombie. If that succeeds in finding a valid zombie spawning point, the siege is started at the chosen starting point. Else, the next player`s village is considered.
Zombie spawning
During a siege, 20 attempts are made to spawn a zombie over the course of 2 seconds. For each zombie, 10 attempts are made to randomly choose a valid spawning point within a 16ℂₗ16ℂₗ6 box around the chosen point. If a valid spawn point is found, a zombie is spawned.
Zombies spawned within a siege ignore player proximity, light levels, and the presence of other mobs. Only the minimal spawning conditions are checked:
- the spawning block must be transparent When leaves are opaque (in "fast" graphics), they completely block rendering. When leaves are transparent (in "fancy" graphics), the world behind them is also rendered. Opacity (and its inverse, transparency) are properties of blocks with

Note in particular that siege zombies can spawn inside transparent blocks such as slabs that normally prevent mob spawning.

For the most part, the zombies that spawn as part of a siege will behave in the same manner as normally-spawned zombies; they will attack all villagers within sight, and villagers and iron golems Iron Golem Health points 100 ( × 50) Attack strength 7 () to 21 ( × 10.5) To players: Easy: 4 () to 11 () Normal: 7 () to 21 ( × 10.5) Hard: 10 
will react accordingly. The zombies will also despawn as usual if the player is far enough away. If the zombies happen to wander away a certain distance (greater than the size of the village) from the center of the village, they will return towards the village center if they are not actively pursuing a target.
Recovery
If at least two villagers survive the siege and doors are rebuilt as necessary, the villagers can mate and repopulate the village. The village will be safe from future sieges until the population reaches 20. Without player intervention, be that as it may, it is likely that villages will be wiped out by sieges and randomly-spawned zombies.
Even if no villagers survive, a village may be repopulated by curing zombie villagers, or by luring in villagers from another village.
