Mebahel’s API — Core Library for Mebahel Mods

Mebahel’s API is a core dependency mod that provides shared systems, utilities, and gameplay frameworks used across the Mebahel mod ecosystem.

It is designed for mod developers who want production-ready building blocks for complex mechanics without rewriting the same infrastructure in every project.

⚠️ This mod is a library. It does not add standalone gameplay content by itself.

Supported Versions

Minecraft 1.20.1 — Fabric
Minecraft 1.21.1 — Fabric

⭐ For Players & Modpack Users

This mod is a technical dependency used by other Mebahel mods.

What it does in a game

You normally won’t interact with this mod directly.
It runs in the background to make other mods work correctly and efficiently.

Depending on the mod that uses it, it may provide:

🌊 Dry Structure Generation

Structures can generate without being flooded, even underwater or inside wet terrain.

📦 Advanced Custom Chests

Some Mebahel mods use special chests powered by this API:

Animated opening and closing
Multiplayer-safe inventories
Optional per-player rewards (each player gets their own loot)
Custom sounds and GUI

⚔️ Improved Mob Behavior

Certain creatures may use advanced movement such as:

Strafing during combat
Tactical retreat when too close
More natural positioning
Reduced “stuck” behavior

Do I need this mod?

✔ Required if another mod lists it as a dependency
✔ Safe for singleplayer and multiplayer
✔ Must be installed on both client and server

❌ Removing it will break mods that depend on it

⭐ For Mod Developers

Mebahel’s API provides reusable systems intended to simplify the development of complex Fabric mods.

Main Systems Provided

🌊 Structure Water Removal System

Prevents structures from spawning flooded in oceans, rivers, or aquifers.

Capabilities

Removes waterlogged states after generation
Clears surrounding water blocks inside structure bounds
Works with template-based structures
Tick-budget safe (no lag spikes)
Fully automated once configured

📦 Advanced Animated Chest Framework

A complete foundation for creating custom containers with multiplayer-safe logic.

Includes

GeckoLib animated open/close/spawn sequences
Built-in sound synchronization
Custom GUI support
Server-authoritative behavior
Multiplayer compatibility

Personal Loot Mode

When using a loot table:

Each player receives individual rewards
Loot is generated once per player
Prevents duplication exploits
Ideal for dungeon or boss chests

Shared Inventory Mode

Without a loot table:

Functions as a normal container
Inventory shared between players

🖥️ Ready-to-Use GUI & Screen Handler

Speeds up development of container blocks:

Preconfigured ScreenHandler
Player inventory integration
Client GUI implementation
Minimal boilerplate required

⚔️ Entity Movement Utilities

Utility methods for advanced combat AI and movement behavior.

Supports:

Strafing around targets
Tactical retreat movement
Target-facing rotation
Jump assistance
Anti-stuck handling

Ideal for bosses, ranged mobs, constructs, or mechanical entities.

🧠 Why Use Mebahel’s API?

✔ Reduces duplicated code across multiple mods
✔ Optimized for server performance
✔ Multiplayer-safe systems
✔ Production-ready implementations
✔ Actively used in real released mods

📦 Used By

All Mebahel ecosystem mods depend on this API as their shared core library.

👨‍💻 Developer Guide — Integration

🌊 Water Removal Processor (Structures)

Automatically removes water and waterlogged states after structure generation.

Use cases

Ocean structures
Underground builds intersecting fluids
Ruins or dungeons that must remain dry

How to enable

Add the processor to your structure configuration:

"processors": "mebahelsapi:water_removal_processor"

The cleanup runs automatically after placement.
Server-side only.

📦 BaseChest Framework — Custom Animated Containers

Provides a ready-to-extend system for animated, synchronized chests.

Creating a Custom Chest

Extend the base chest block
Extend the base chest block entity
Register them normally
Configure title, sounds, and multiplayer behavior

Example — ChestBlockEntity:

public class DwemerChestBlockEntity extends BaseChestBlockEntity {
    public DwemerChestBlockEntity(BlockPos pos, BlockState state) {
        super(ModBlockEntities.DWEMER_CHEST_ENTITY, pos, state, 36);
    }

    @Override
    protected Text getChestTitle() {
        return Text.translatable("block.mebahelcreaturesdwarven.dwemer_chest");
    }

    @Override
    protected String getLogPrefix() {
        return "[DwemerChest]";
    }

    @Override
    @Environment(EnvType.CLIENT)
    public void playOpenSound() {
        playChestSound(ModSounds.DWARVEN_CHEST_OPEN);
    }

    @Override
    @Environment(EnvType.CLIENT)
    public void playCloseSound() {
        playChestSound(ModSounds.DWARVEN_CHEST_CLOSE);
    }

    @Override
    protected boolean isMultiplayerEnabled() {
        return ModMultiplayerChest.turnOnMultiplayerDraugrChest;
    }
}

Example — ChestBlock:

public class DwemerChestBlock extends BaseChestBlock {
    public DwemerChestBlock(AbstractBlock.Settings settings) {
        super(
                settings,
                () -> ModBlockEntities.DWEMER_CHEST_ENTITY,
                DwemerChestBlockEntity::new
        );
    }

    @Override
    protected boolean isMultiplayerEnabled() {
        return ModMultiplayerChest.turnOnMultiplayerDraugrChest;
    }
}

🏹 MovementUtil — Advanced AI Positioning

MovementUtil provides reusable helpers for combat movement, especially for ranged entities.

Typical responsibilities:

Keep the entity facing its target
Prevent pathfinding stalls
Maintain optimal distance
Control strafe and retreat behavior

Recommended usage pattern inside a Goal:

Validate target
Face the target
Run anti-stuck logic
Choose movement based on distance
Handle attack timing separately

Example — Shooting Goal (Draugr Archer):

public class DraugrArcherShootingGoal extends Goal {
    private final DraugrArcherEntity actor;
    private final MovementUtil movementUtil;
    private final double STRAFE_DISTANCE = 8;

    public DraugrArcherShootingGoal(DraugrArcherEntity actor) {
        this.actor = actor;
        this.movementUtil = new MovementUtil(this.actor);
    }

    @Override
    public void tick() {
        if (actor.isUsingPotion() || actor.getHealTicks() > 0) {
            actor.setShooting(false);
            actor.getNavigation().stop();
            return;
        }

        LivingEntity target = this.actor.getTarget();
        if (target == null || !target.isAlive()) {
            this.stop();
            return;
        }

        double distanceToTarget = this.actor.distanceTo(target);

        movementUtil.lookAtTarget(target, actor);
        movementUtil.checkIfStuck(target, actor);

        if (distanceToTarget <= STRAFE_DISTANCE) {
            movementUtil.moveBackward(target, actor);
        } else {
            movementUtil.strafeAroundTarget(target, actor);
        }

        // Shooting logic handled separately
    }
}

This separation keeps movement smooth while allowing precise control over attack timing and animations.
