Effect.SetOperation

Signature

Effect.SetOperation(Effect e, nil|function op_func) -> void

Description

Sets e's operation callback. Passing nil clears the operation. For activated effects, this callback resolves after the Chain reaches this Link, so it should re-check targets, locations, relation, and other state that may have changed since activation.

How To Use It

The operation callback performs the effect when the Chain resolves.

For targeted cards, retrieve the target and re-check that it is still related to the resolving effect before applying the action:

function s.operation(e,tp,eg,ep,ev,re,r,rp)
    local tc=Duel.GetFirstTarget()
    if tc and tc:IsRelateToEffect(e) then
        Duel.Destroy(tc,REASON_EFFECT)
    end
end

Passing nil to SetOperation clears the operation. That is occasionally useful for effects whose category or target data is enough and no resolution callback is needed.
