Setting an entity to a variable help.

[sharp beacon]

When I try to set a entity (In this case an attacker) to a variable, it gives me the error:
"an entity can't be set to anything"
What should I do?

CODE:

    if attacker is player:
        set attacker to {burnpig::%attacker%}```

You have to set the variable to attacker

What you’re doing right now is the same thing is typing “set creeper to pig”

Or “set player to bee”

It just doesn’t work

But “set {_e} to attacker” will
