/p new door , (place a block) , /p , /b new doorknob , /ac set height X (x - number on how height you want your elevator to go) , /ac add height X (x - number on how platform will be height when it will be at the bottom).
Thanks, so but I do not understand anything of what to type and what you need to do write me everything how it works speed was [speed=2.0] terminal command to speed up and down and at height
step 3: make button do elevator
type /ac set height 10 to make platform go to 10
or type /ac set raise 10 to make platform go up 10
or type /ac set elevator 10 0.25 3 to make platform wait 3 seconds before go to 10 and then go back in 0.25 seconds per block (less than a second (very fast))
after type (type = write) dig platform and dig button
Step 4: button to go back (down) (skip this if you use /ac set elevator)
type /ac set height 1
0 is block on water, its bedrock
1 is block above bedrock, I can destroy block
