Concept:
A block that, when powered, generates a 15-block long line of red barrier blocks. Late game, to be added if redstone analogs are added
Description:
A laser bridge is a hex-block with a laser lens on one face, determined by placement. When a power source is connected, it will generate a line of blocks from the lens. If a solid block is placed on this path, the laser bridge will end there.
Laser emitters are dark metal, with a red lens. The lens can be on any of the 8 sides. Laser emitters generate a 15-hex long (harmless) laser beam when deactivated, replaced with holographic blocks when in use. Laser bridges make an electrical crackle when activated.
Contact with a laser bridge will be treated as a solid block. Blocks can be placed on it while active. Laser bridges can be placed side by side if desired. If the power source or emitter is destroyed, the laser bridge vanishes.
Uses:
Fast and easy drawbridges or doors, able to be toggled with a mere lever. Aesthetics may clash
Puzzles and parkour, with players needing to deactivate emitters, or time their jumps to make use of/avoid them. This would allow for some interesting maps.
These were inspired by portal, but I think they'd work well for both survival and creative Planetsmith players
