I'm trying to make an adventure game, and I'm making springs, but I can't seem to get the /testfor command to work. What do I do?

  • What's the whole command you tried? Mar 12 at 8:47
  • /testfor @a[x=(xpos) y=(ypos) z=(zpos) r=1] Mar 23 at 13:46
  • After that I use a fill command. Mar 23 at 13:50

You need to use /execute

/execute @a[x=6,y=3,z=10,dx=1,dy=0,dz=1] ~ ~ ~ effect @s levitation 1 1 true

Within the target selector @a[] you specify the starter coordinates with x=, y=, z=, and then the distance with dx=, dy=, dz=. the dx dy dz is the difference, so if x=10 and dx=5 you test for an area from 10 to 15, and this works the same for the other once as well both for positive numbers and negative.

  • There's a slight problem there. I use Edu edition. And I've tried the dx, dy, and dz. It just says syntax error. Plus, I'm using a fill command with sticky pistons and slime blocks. Not an effect command. Mar 23 at 13:50
  • I'll try it out in the Edu version later. It sould work. Just let me know: Do you intend to fill in the pistons and slimes at the same time or with a delay? Mar 23 at 16:09
  • I intend to fill the block under the sticky piston with a redstone block. Mar 23 at 17:35
  • The command works fine for me, you can also replace the dz, dy ,dz with r=1. And replace effect etc. with fill x y z x2 y2 z2 redstone_block, but if you'r only setting one block you should use setblock x y z redstone_block instead. Mar 23 at 22:33
