Mantle Gameplay Mechanics

Mantle adds several subtle but impactful mechanics to the game that are often utilized by its dependent mods.

Health Overlay

One of Mantle's most recognizable features is the Colored Heart Overlay. In vanilla Minecraft, gaining extra health (via potions or equipment) results in multiple rows of hearts stacking vertically, which can obscure the screen. Mantle replaces this with a color-coded system where hearts change color to represent additional health layers:

• Red Hearts: Standard 10 hearts (20 HP)
• Orange/Yellow/Green/Blue Hearts: Represent subsequent layers of health. Each color indicates a full extra bar of health has been added

Soulbound Items

Mantle introduces the mantle:soulbound item tag. Any item added to this tag via a data pack will be automatically kept in the player's inventory upon death, rather than dropping on the ground. This logic is natively supported by Tinkers' Construct and can be utilized by other mods using Mantle's event bus.

In-World Fluid Gauges

In version 1.20.1, Mantle adds a dynamic tooltip system for fluids. By adding blocks to specific tags, players can see fluid contents just by looking at them:

• mantle:gauges/attached: Blocks in this tag show a tooltip of the fluid contents in the tank directly behind them
• mantle:gauges/tank: Blocks in this tag show their own internal fluid contents as a tooltip
• mantle:hides_gauge_amount: Blocks with this tag will only show the fluid name, hiding the specific millibucket (mB) amount
