Group.IsExists

Signature

Group.IsExists(Group g, function f, int count, [Card|Group|nil ex], ... any) -> bool

Description

Checks whether at least count cards in g satisfy filter f and are not excluded by ex. Extra arguments after ex are passed to f after the card argument.

How To Use It

Use this to check whether a Group contains enough cards with a property.

if g:IsExists(Card.IsRace,1,nil,RACE_DRAGON) then
    -- at least one Dragon is in g
end

The count parameter is useful for requirements such as "2 or more monsters with different names" once the filter captures the condition you need.

Parameters

• g Group
• f function
• count int
• ex Card|Group|nil optional
• ... any

Returns

• bool
