This is a single Minecraft command that adds a fully functional space laser cannon to your Minecraft world! You don't need any mods, just a command block.

Get the command (updated to Minecraft version 26.2):
► ijaminecraft.com/cmd/space_laser_1.12

Supported Minecraft versions:
26.2, 26.1.x, 1.21.11-1.21.9, 1.12

▬▬▬▬▬▬▬▬▬▬▬▬▬

Get a command block, paste the command inside, and activate it. Once it's finished, you can craft a #LaserCannon by throwing a nether star onto a diamond block.

There's a button on the cannon that provides you with targets. Place a target down so the cannon can fire its laser beam at it.

Activate the cannon by placing a redstone block in each of the 4 empty power cells of the cannon. Once activated, the cannon fires a #LaserBeam into space, which will then come down onto the target with fiery destruction!
