Energy Flashlight

📖 About

This datapack adds a flashlight that casts light across the entire beam path.

Important information:

Instructions for charging a flashlight will always be in the description of the flashlight at zero energy, but I'll repeat it here: the player must hold the flashlight in the main hand, the redstone dust in the off hand, sneak and use the flashlight.
The maximum possible charge for a flashlight is 10 redstone dusts, each redstone dust adds 6 minutes of real-time operation, as a result, the flashlight can be charged for 1 hour. If the flashlight is on, the energy is used up and the next time you pick it up, the battery status will be updated, if more than an hour has passed, the flashlight will turn off immediately. This is achieved by storing the gametime in an item, and when the player holds a flashlight, the datapack compares the saved time with the current one.

🧩 Add-ons & Technical info

Custom light beams

If you want to add custom light beam, you can do it, but first you need to know: the datapack tick function runs on a 2-tick schedule for optimization, so I added the #energy_flashlight:tick functions tag. You can add your own functions for the spawn light beam to this tag.
Why is this necessary?
1) To optimize the light sources so that their life is handled only in this datapack;
2) To avoid bugs, the life of light sources must be processed after they are spawned and updated.

So, to spawn a light beam, you need to set its length and run the function.
The length is measured in 0.5 blocks, that is, the length of the raycast 10 is equal to (<=)5 blocks.

# The base length is 20 blocks.
scoreboard players set #raycast main_score 40
execute anchored eyes positioned ^ ^ ^ run function energy_flashlight:other/raycast/loop

Custom charging item

The charging flashlight always accepts only vanilla redstone dust without any custom components, but if you add the energy_flashlight.energy_for_flashlight:true nbt tag to the minecraft:custom_data component, then this item can be used as a charger.
