Solved How to check if world exists?

[CassioTDS]

Hello, I tried making a command that uses multi-verse to create worlds (make console execute "mv create world") but when I try making the world join command, I am stuck with: if world arg 2 exists: . It dosen't work... Any help? I am using skript 1.15

if ("world" parsed as world) is set:
    send "this world exists"
else:
    send "this world does not exist"
