Monster Spawner Generator (Java Edition 1.19/1.20)

Instructions: Select the options to apply to the monster spawner. The options are as follows:

• Spawn Range - The number of blocks away from the spawner that the mob can spawn.
• Spawn Count - The maximum number of mobs that can spawn each time (the actual number that will spawn will be between 1 and this number and will vary each time a spawn occurs).
• Max Nearby Entities - The maximum number of mobs (with that Entity ID) that can spawn within the Spawn Range.
• Delay - The number of game ticks before the first mob will spawn after the monster spawner has detected a player.
• Min Spawn Delay - After the first spawn, the minimum wait time (in game ticks) until the next spawn occurs.
• Max Spawn Delay - After the first spawn, the maximum wait time (in game ticks) until the next spawn occurs.
• Required Player Range - The number of blocks away from the spawner a player can be before the spawner is activated.

Instructions: Select the positioning type and enter the position where you would like the monster spawner to spawn.
Relative positioning will spawn the monster spawner at a position in relation to where the command is run.
Absolute positioning will spawn the monster spawner at a specific coordinate in the world.

The coordinate system works as follows:

• X - A positive value increases position to the East. A negative value increases position to the West.
• Y - A positive value increases position upward. A negative value increases position downward.
• Z - A positive value increases position to the South. A negative value increases position to the North.

TIP: Use X=0, Y=1, Z=0 with Relative Positioning when you want to spawn the monster spawner above a command block.

Instructions: Select the options to apply to the mob. The options are as follows:

• Age - The age of the Zombie (Adult is the regular size. Baby is younger and smaller)
• Invulnerable - Prevent the Zombie from being killed in Survival mode
• Persistent - Prevent the Zombie from naturally despawning
• Silent - Prevent the Zombie from making any noise
• NoAI - Prevent the Zombie from normal AI movements
• Can pick up loot - Allow the Zombie to pick up loot
• Can break doors - Allow the Zombie to break down wooden doors
• Left Handed - The Zombie is left-handed (rather than right-handed)

Instructions: Select a mob to ride. Commonly, you would choose a mob such as a horse, skeleton horse, chicken, spider or pig. But you can choose any one of the mobs listed in the dropdown. This allows you to stack one mob on top of another.

Instructions: Select a weapon from the dropdown. Then select the chances of the mob dropping the weapon when killed (100% means the weapon will always be dropped and you can add it to your inventory). You can also add a custom name for the weapon and any lore or information about the weapon.

Note: If the mob is not capable of carrying a weapon, you will not be able to select a weapon from the dropdown.

TIP: In the steps that contain Lores, you can get multi-line Lores by separating each line of the Lore with a | character. For example: if you enter The greatest sword|EVER in the Lore field, you will get a two line Lore. The first line will contain The greatest sword and the second line will contain EVER.

Instructions: Select armor from the dropdown. Then select the chances of the mob dropping the armor when killed (100% means the armor will always be dropped and you can add it to your inventory). You also add a custom name for the armor and any lore or information about the armor.

Note: If the mob is not capable of wearing armor, you will not be able to select armor from the dropdowns.

Instructions: Add effects (ie: potion effects) to your mob by clicking the appropriate checkboxes. Once you select an effect, you will be able to set the duration and choose whether particles are shown.

• Duration - The length of time that the status effect will last (in game ticks)
• Show Particles - Whether particles are shown for the status effect

Note: You can add more than one effect to a mob, but you can not add the same effect more than once. For example if you add the effect called Strength, you can not also add Strength II as a second effect. Both are the Strength effect with different amplifier values.
