in the world I have 2 command blocks. one says /clear @p[x=-140,y=67,z=-22,r=2] 278 (when you are within 2 blocks of coordinate -140,67,-22 you will have a diamond pickaxe taken away from you) and the other says /tp @p[x=-140,y=67,z=-22,r=2] -147 192 -17 (so when you are within 2 blocks of coordinates -140,67,-22 you will be teleported to -147,192,-17). they are both activated at the same time, but you only get teleported to -147,192,-17 and you don't get the diamond pickaxe taken away from you. also it looks like the coordinates are links on this website
