Duel.GetOperationInfo

Signature

Duel.GetOperationInfo(int chainc, int category) -> bool,Group|nil,int|nil,int|nil,int|nil

Description

Returns operation information recorded for category on chainc. The first return value is false when that category is not recorded. Otherwise, the remaining values correspond to Duel.SetOperationInfo: targets, count, target_player, and target_param. Use this in response checks that need to inspect what a Chain Link announced, such as whether it is expected to destroy cards, move cards from a location, or change LP.

How To Use It

Use this in response checks or follow-up operations that need to read what a Chain Link announced with Duel.SetOperationInfo.

local ex,g,ct,p,loc=Duel.GetOperationInfo(ev,CATEGORY_TOHAND)
if ex and bit.band(loc or 0,LOCATION_DECK)~=0 then
    -- the Chain Link announced adding from the Deck
end

The first return value is false when that category was not recorded. The remaining values mirror the targets, count, target_player, and target_param arguments.
