Torched
The Torched mod offers an innovative solution for automating torch placement in Minecraft, providing three unique devices that fundamentally change the approach to lighting dungeons and construction sites.

Torch Gun

This is the most practical tool in the entire arsenal. The torch gun automatically scans your inventory and determines the number of available torches. The weapon's durability displays the remaining uses of flint and steel for igniting torches when fired. Simply right-click to shoot a torch from your inventory. Hitting mobs causes damage, and upon collision with a block, the device attempts to place a torch. If placement is impossible, the torch will drop as a regular item.
Torch Rocket

The perfect tool for mass lighting of large areas. Place the rocket on the ground and add gunpowder or torches by right-clicking (maximum 512 units or 8 stacks). You can load an entire stack at once. The optimal ratio is 3 torches per 1 unit of gunpowder. Launch is performed using flint and steel (slow option) or by igniting/activating with redstone (fast launch). Additional feature: adding gold nuggets (up to 16 pieces) allows varying the flight trajectory.
Launcher and Ammunition

This system requires special ammunition - "rocket-propelled torches". Stock up on sufficient projectiles in your inventory and use the RPT (Rocket-Propelled Torch) launcher to open fire.
