A simple (Jumpdrive)[https://en.wikipedia.org/wiki/Jump_drive] for minetest Convert your buildings to working spacecrafts and jump them around the map

• Place a 'jumpdrive:engine' into the center of your creation.
• Insert mese crystals as fuel for the jumps
• Choose your target coordinates (should be air or ignore blocks)
• Select your cube-radius (from 1 to 19 blocks)
• Set Cascade button to "ON" (Workaround for now)
• Click "show" and check the green (source) and red (target) destination markers if everything is in range
• Click "jump"

• Mesecon interaction (execute jump)
• Technic rechargeable (HV)
• Travelnet box (gets rewired after jump)
• Elevator (on_place gets called after jump)

• Place multiple engines in the radius of each other and enable the cascade mode
• Execute jump and it will execute all engines relative to each other to the target
• Write and read coordinates to books

• Fix "Cascade" mode
• Performance (for-iterations)
• Dead objects after jumps
