Energy Flashlight Modification

Energy Flashlight - Redstone-Powered Flashlight

This datapack modification adds a modern flashlight to the game that illuminates the entire path of its beam!

🔦 Main Purpose

Dealing with darkness in mines or caves? Now you have a reliable solution - a flashlight that uses redstone as an energy source and creates realistic lighting along the entire beam path.

⚙️ Important Features

Technical requirements: For proper light passage through incomplete blocks (such as slabs) you need to install the library datapack MIDWUT. Currently available in Russian, English, and Old Slavic languages.

Key Characteristics:

• Redstone particles are used as an energy source
• Realistic lighting system using light blocks
• Automatic charge consumption even when flashlight is not in hand
• Illumination range - 20 blocks forward with full beam path coverage

🛠️ Acquisition and Usage

Player can craft the flashlight or get it using command: /function energy_flashlight:give/flashlight

The crafting recipe becomes automatically available upon obtaining redstone lamp or redstone dust.

Charging Process: When flashlight charge reaches zero, charging instructions appear: hold flashlight in main hand, redstone dust in offhand, press Shift and use the flashlight.

Charging parameters:

• Maximum capacity - 10 units of redstone dust
• Each unit provides 6 minutes of real-world operation time
• Total operation time at full charge - 1 hour

💻 Technical Information for Developers

Custom Light Beams

The modification allows creating custom light beams. Note that the datapack tick function runs on a 2-tick schedule for optimization, so I added the function tag #energy_flashlight:tick. You can add your own functions for creating light beams to this tag.

Why this is necessary:

1. Optimize light source processing through unified mechanism
2. Avoid synchronization errors during light block updates and removal

To create a custom light beam, you need to set its length and run the corresponding function. Length is measured in 0.5 block units, for example, beam length of 10 units equals 5 blocks.

# Basic range reaches 40 units
scoreboard players set #raycast main_score 40

Alternative Charging Items

By default, flashlight accepts only vanilla redstone dust. However, if you add the tag energy_flashlight.energy_for_flashlight:true to the minecraft:custom_data component of any item, it can also be used for energy replenishment.

Operation Notes:

• System saves game time in the item and compares it with current time when picked up
• If more than an hour has passed since last use, flashlight automatically turns off
• Battery status updates every time flashlight is picked up
