MmmMmmMmmMmm — a mod to add a training dummy and measure damage in Minecraft

MmmMmmMmmMmm adds one new item to Minecraft — a training dummy. The vanilla game does not provide a convenient way to check how much damage a weapon deals or how enchantments affect it: you have to look for mobs that do not show specific numbers. The dummy from the mod solves exactly this problem — it stands still, absorbs hits, and shows the amount of damage dealt right above itself. 

How to get the dummy

The recipe takes two slots in the Crafting Table: a Hay Bale above an Armor Stand. The dummy is given as an item, which is then placed into the world with a right-click on a block.

Crafting recipe for the training dummy

When placed, the dummy is oriented in 16 directions depending on the player's position — just like an Armor Stand. You can remove it by using Shift + left click with an empty hand. If the block under it is broken, the dummy also breaks and drops as an item. 

Damage numbers and DPS

When hit, a damage number appears above the dummy. Each attack type has its own color: fire — orange, poison — purple. A few seconds after the last hit, a DPS line appears on the status bar — the average damage per second for the last series.

The player strikes the dummy with a sword, and the DPS line on the status bar updates in real time. 

In the client config file, you can switch the numbers to hearts (1 heart = 2 damage), turn off the display entirely, or change the dummy's swaying intensity. There is also a separate mode for showing crits: color only, or color + multiplier. 

Changing mob type

The dummy mimics a mob type depending on what it is wearing. This way you can test enchantments that only work against specific categories of mobs:

• Zombie Head, Skeleton Skull — the dummy is considered undead, and corresponding enchantments work as they do on undead mobs.

• Turtle Shell — the dummy is considered an aquatic mob. 

• Player Head — other mobs start attacking the dummy as a player, if dummy_decoy is enabled in the config. Useful for testing hostile AI or as bait for building mob farms.

Boss mode

If you give the dummy any Banner, it enters boss mode: a boss health bar appears at the top of the screen, and the dummy itself gets 200 HP by default. In the common.json file, you can change the amount of health (1 – 1 000 000) and the color of the bar (PINK, BLUE, RED, GREEN, YELLOW, PURPLE, WHITE).

Pumpkin scarecrow

If you equip the dummy with a Pumpkin or Jack o'Lantern, it starts scaring animals within a 12-block radius (the value is changed in the config). The radius is any number from 0 to 100. There is no obstacle check, the scarecrow works through walls. In the config, there are two lists — mobs_whitelist and mobs_blacklist — where you can add mob IDs that the scarecrow should or should not affect.

Config — main parameters

The files are located in config/.  Below is what is actually needed during the game. The rest of the values from the file are auxiliary (for example, exact hex codes for each type of damage) and are only changed for specific tasks.

Conclusion

MmmMmmMmmMmm provides a testing ground for checking damage, enchantments, and long combo hits without spending resources on real mobs. It is suitable for players balancing modded gear, testing weapon builds before PvP, or setting up redstone contraptions with a damage trigger.
