What is GlymeraTNT?

GlymeraTNT adds a complete explosives system to your Hytale server. Players can craft and place 6 different explosive blocks — 3 standard TNT types that create spherical explosions of increasing size, and 3 Tunnel TNT types that blast directional cylindrical tunnels through terrain. All explosives feature a 4-second countdown with a visual blinking effect and audible beeping before detonation.

TNT can be activated in two ways: right-clicking the block with an empty hand, or by connecting it to Wire from the GlymeraBluestone plugin for automatic remote detonation. Both methods trigger the same countdown sequence. Tunnel TNT destroys all blocks in its path without drops. All explosions deal massive damage to nearby entities (players, NPCs, animals) and cannot destroy Bedrock.

TNT Types

Standard TNT (Spherical Explosion)

Standard TNT creates a sphere-shaped explosion centered on the TNT block.

Small TNT — GlymeraTNT_Small

• Explosion Radius: 10 blocks
• Recipe: 1x Iron Bar + 1x Boom Powder

Medium TNT — GlymeraTNT_Medium

• Explosion Radius: 15 blocks
• Recipe: 1x Iron Bar + 4x Boom Powder

Large TNT — GlymeraTNT_Large

• Explosion Radius: 20 blocks
• Recipe: 1x Iron Bar + 8x Boom Powder

Tunnel TNT (Directional Cylinder Explosion)

Tunnel TNT creates a cylindrical explosion in the direction the block is facing. The tunnel always has a radius of 5 blocks. All blocks in the cylinder are destroyed (no drops). The direction is determined by block rotation (North/South/East/West) or by placement height relative to the player (Up/Down variants).

Short Tunnel — GlymeraTunnel_Short

• Tunnel Length: 20 blocks (Radius: 5 blocks)
• Recipe: 1x Iron Bar + 1x Boom Powder + 1x Crude Arrow

Medium Tunnel — GlymeraTunnel_Medium

• Tunnel Length: 30 blocks (Radius: 5 blocks)
• Recipe: 1x Iron Bar + 4x Boom Powder + 1x Crude Arrow

Long Tunnel — GlymeraTunnel_Long

• Tunnel Length: 40 blocks (Radius: 5 blocks)
• Recipe: 1x Iron Bar + 8x Boom Powder + 1x Crude Arrow

All recipes are crafted at the Alchemist's Workbench. Recipes can be enabled or disabled in the plugin config.

How to Obtain

Each TNT and Tunnel block can be obtained via crafting (see above) or by using the /give command:

• /give GlymeraTNT_Small
• /give GlymeraTNT_Medium
• /give GlymeraTNT_Large
• /give GlymeraTunnel_Short
• /give GlymeraTunnel_Medium
• /give GlymeraTunnel_Long

How It Works

1. The player places any TNT or Tunnel block.
2. The player activates the block by right-clicking it with an empty hand, or by powering it with Bluestone (automatic activation).
3. A 4-second countdown begins. The TNT block blinks with a red/orange overlay (DebugShape) and emits a beeping sound. The blink frequency increases as detonation approaches — slow at first, faster in the final second.
4. After 4 seconds, the explosion triggers:
   • Standard TNT: All blocks within the sphere radius are destroyed. Entities within the blast radius + 5 blocks take massive damage (9999 HP).
   • Tunnel TNT: All blocks within the cylindrical area (5-block radius, configurable length) are destroyed. No block drops. Entities near the tunnel center take massive damage.
5. Explosion particles and sound effects play at the detonation point.
6. The TNT block itself is consumed in the explosion.

Tunnel Direction

Tunnel TNT blasts in the direction the block is facing when placed. Horizontal direction (North/South/East/West) is determined by block rotation. If the player places the block significantly above their head, it switches to the Up variant. If placed significantly below their feet, it switches to the Down variant. This allows for vertical tunnel boring.

Countdown Cancellation

Breaking a TNT block during the countdown cancels the explosion. The block is removed, the countdown stops, and no detonation occurs.

Activation Methods

Manual Activation (Right-Click)

Right-click any placed TNT or Tunnel block with an empty hand to start the countdown. The player receives a chat message: "TNT activated! 4 seconds to detonation!"

Bluestone Wire Activation (Automatic)

TNT blocks can be activated remotely using Wire from the GlymeraBluestone plugin. Connect a Bluestone Wire to the TNT block and send a signal — the countdown starts automatically. This allows TNT to be integrated into full Bluestone circuits for remote detonation, timed sequences, or chain reactions. Any Bluestone component that outputs a signal (Lever, Pressure Plate, Pulse, etc.) can trigger the TNT through Wire.

Features

• 6 explosive types — 3 spherical (Small/Medium/Large) and 3 directional (Short/Medium/Long) for different use cases
• 4-second countdown — Visual blinking overlay and audible beeping give players time to retreat. Blink speed increases as detonation approaches
• 0 % block drop chance — Standard TNT drops a portion of destroyed blocks as items. Tunnel TNT destroys everything cleanly
• GlymeraBluestone Wire compatible — Connect TNT to Wire from the GlymeraBluestone plugin for remote detonation, chain reactions, or automated systems
• Manual activation — Right-click with an empty hand for quick detonation
• Directional tunneling — Tunnel TNT respects block rotation (N/S/E/W) and supports Up/Down variants for vertical boring
• Entity damage — All entities (players, NPCs, animals) within the blast zone take massive damage (9999 HP)
• Bedrock protection — Bedrock blocks are never destroyed by any explosion type
• Countdown cancellation — Break the TNT block during countdown to cancel the explosion
• Craftable at Alchemist's Workbench — All 6 types have recipes using Iron Bars, Boom Powder, and Crude Arrows
• Explosion effects — Particles and sound effects accompany every detonation
• No config file required — All parameters are hardcoded for simplicity. Works out of the box

Explosion Properties Overview

Standard TNT

All standard TNT types create spherical explosions.

• Small TNT — Radius: 10 blocks, Entity Damage Radius: 15 blocks
• Medium TNT — Radius: 15 blocks, Entity Damage Radius: 20 blocks
• Large TNT — Radius: 20 blocks, Entity Damage Radius: 25 blocks

Tunnel TNT

All tunnel TNT types create cylindrical explosions with a fixed 5-block radius. No block drops.

• Short Tunnel — Length: 20 blocks
• Medium Tunnel — Length: 30 blocks
• Long Tunnel — Length: 40 blocks

All explosions deal 9999 HP damage to entities within range.

Installation

1. Stop your Hytale server.
2. Copy GlymeraTNT.jar into your server's mods/ folder.
3. Start your server.

No additional dependencies, asset packs, or configuration files required — everything is included in the single JAR file.

Known Limitations

• No block-breaking particles — Blocks are removed with setBlock("Empty") which does not generate native breaking animations. Explosion particles are spawned separately at random positions within the blast zone.
• Particle budget — A maximum of 200 particles are spawned per 3-second window to prevent client lag during large explosions.
• Pathfinding irrelevant — TNT is a static block with no NPC interaction. Explosions are instant after the countdown.
• No chain reactions — Explosions do not trigger nearby TNT blocks. Each TNT must be activated individually or via Bluestone.
• Tunnel direction accuracy — Horizontal rotation depends on Hytale's chunk rotation index. In rare cases, the rotation may not match the visual orientation perfectly.
