[MCPE 1.21+] Heart Thief Addon: Lifesteal SMP System (Steal Hearts & Bank)
The "Lifesteal SMP" genre has taken the Minecraft community by storm. The concept is simple but brutal: if you kill a player, you steal their heart and add it to your own health bar. If you die, you lose a heart. Run out of hearts, and you are banned (or eliminated). It creates a high-stakes environment where every PvP encounter matters.
I am excited to release the RR Heart Thief Addon. This is a fully scripted Lifesteal system for Minecraft Bedrock Edition (1.21+). Unlike other mods that require complex texture packs or behavior setups, this addon works out of the box with No Resource Pack Needed. It uses vanilla items like Nether Stars and Gold Ingots to manage the heart economy.
In this post, I will explain the stealing mechanics, the unique "Heart Bank" system, and how to unlock the Pro Mode to revive your fallen teammates.
Core Mechanics: Steal, Lose, Eliminate
This addon modifies the player's attribute files dynamically using the Script API.
1. The Steal System
Combat is high-risk, high-reward. When you deliver the killing blow to another player:
- You Gain: +1 Heart Container (Permanent Health Boost).
- They Lose: -1 Heart Container.
- Limit: By default, you can stack up to 20 Hearts (double health). Pro mode increases this cap to 40 Hearts.
2. Death Consequence
Dying to environmental causes (Lava, Fall Damage, Creepers) is also punished. You will lose a heart upon any death. This forces you to play carefully even when not fighting players.
3. Elimination State
If your heart count drops to zero, you are "Eliminated." You are not banned from the server, but you are rendered useless.
- Effects: Blindness, Slowness V, Mining Fatigue, and Weakness.
- Gameplay: You enter a spectator-like state where you cannot fight or mine. You must wait for a teammate to revive you.
The Heart Economy (Banking)
What makes Heart Thief unique is the ability to trade health using physical items. You can withdraw your own health to store it safely in a chest.
Withdraw Hearts
Hold a Gold Ingot and Crouch (Sneak). The addon will subtract 1 Heart from your body and give you a Nether Star item.
Deposit (Consume) Hearts
Hold a Nether Star and Crouch. You will consume the star and gain +1 Heart permanently.
Interface and Controls
The addon features a comprehensive stats panel to track your PvP performance.
| Action | Input Command |
|---|---|
| Open Stats | Hold Book + Sneak |
| Withdraw Heart | Hold Gold Ingot + Sneak |
| Consume Heart | Hold Nether Star + Sneak |
| Open Admin Menu | Hold Name Tag + Sneak |
