Help with checking there is a clear view of the sky?

[Akaramine]

I have an object that's used to teleport a player to a saved location (works great!), but I only want it to work if the player has a clear view of the sky.

I tried searching here and couldn't find anything, so I apologize if there is something here already and I missed it.

How do I go about checking if there are any blocks between the player and sky?

Thanks!

on command /useobject: #or on right click with "object"
  set {clearsky.%player%.altitude} to player's y-coordinate
  loop blocks from the block above the player to the block block %integer of 256 minus {clearsky.%player%.altitude}% above the player:
    if the loop-blocks are equal to air:
    #do stuff
    else:
    #do stuff

Not tested.

Thanks! I'll give this a shot as soon as I get a chance

Can't understand this loop: 'loop blocks from the block above the player to the block block %integer of 256 minus {clearsky.%player%.altitude}% above the player' (test.sk, line 3: loop blocks from the block above the player to the block block %integer of 256 minus {clearsky.%player%.altitude}% above the player:')

loop blocks from the block above the player to the block %integer of 256 minus {clearsky.%player%.altitude}% above the player:

same result

Ok I tried it by just using "loops blocks above the player"

it works, but It performs the "else" result for every block that is air. I added a stop for when it isn't air or it peforms that one for every block that isn't air.

Actually i think that will work if i use an if the loop block isn't air, stop. And have it continue only if all blocks are air, otherwise the whole script stops. Not putting it in a "else" statement

I'll paste my example

 

[ShaneBee]

on command /useobject: #or on right click with "object"
 loop blocks above the player: 
    if all the loop-blocks are equal to air:
    #do stuff
    else:
    #do stuff

maybe by adding "if all"?

this does it! Thanks for getting me on the right track

on right click:
    set {clearsky.%player%.altitude} to player's y-coordinate
    loop blocks above the player:
        if the loop-blocks are not equal to air:
            send "BLOCKS"
            stop
    send "ALL CLEAR"

I remembered running into this before with loops when creating a blacklist. Same approach worked here as well

You don't need the "set {clearsky.%player%.altitude} to player's y-coordinate" line.

Remove it.

on right click:
    loop blocks above the player:
        if the loop-blocks are not equal to air:
            send "BLOCKS"
            stop
    send "ALL CLEAR"

Ah, after removed it from the other line i forgot that line was in there when I did the paste. Thanks!
