About

AkatZumaTool is a lightweight weapon mod for Minecraft that uses a custom rendering pipeline to deliver flashy visual effects.

All beams, lightning, and explosion particles are rendered in real-time via custom Shaders, supporting up to hundreds of thousands of particles for a greatly enhanced visual experience.

Note: The GPU particle and post-processing systems require OpenGL 4.3 (satisfied by most discrete GPUs).

New Items

Item Description Coin Right-click and hold to charge, release to fire a piercing beam. Consumable item. Max range 50 blocks, damage 20. Colorful Coin Enhanced version of the Coin with 256 durability. Enchantable, max range 60 blocks, damage 40. The beam can also break blocks. Fly Sword Right-click on a block to summon 2 auto-targeting flying swords. Persistent entities that automatically follow and attack monsters, with a trailing visual effect. other Github Wiki

Additional Features

✨ GPU Particle System (Compute Shader)

Engine: OpenGL 4.3 Compute Shader + SSBO
Capacity: Up to 100,000 particles, updated primarily on the GPU
Particle Shapes: Circle, Square, Triangle, Heart, Star
Motion: Ballistic trajectory, gravity control, color gradient
Use Cases:
- Coin full-charge convergence particles
- Magic arrow trails
- Impact explosion bursts
- Meteor strikes
- Ground expanding rings
- Super charge final explosion

🌟 Bloom Post-Processing Pipeline

MRT FBO: Separates the visible color pass from the Bloom glow pass
Gaussian Blur: 3-iteration ping-pong blur
Final Composite: Original scene + mod effects + Bloom glow overlay
Adaptive Resolution: FBOs automatically rebuild on window resize

⚡ Custom Beam & Lightning Rendering

Beams: 3D beams formed by two perpendicular quads, with fbm noise arc disturbance and blue-white / yellow-red color schemes
Lightning: Real-time branching lightning (3–8 branches) generated during charging, with exponential decay kernel + Bloom glow
Sword Trail: 6-frame dynamic ribbon effect based on the Ribbon algorithm

🤝 Mod Integration

Touhou Little Maid: Registers a ranged attack task (Railgun) so maids can automatically equip and throw coins as a ranged weapon — no extra configuration needed.

⚙️ Configurability

Most numerical values can be adjusted via config/Akatzumatool/akatzumatool.toml:

Config Key Description Coin / Colorful Coin Damage, range, full-charge time Fly Sword Search range, attack damage Terrain Destruction Whether beams can break terrain (respects FTB Chunks claims)
