Duel.CheckLPCost

Signature

Duel.CheckLPCost(int player, int cost, [bool must_pay]) -> bool|nil

Description

Checks whether player can pay the specified LP cost without paying it. Use this in a Cost callback's chk==0 branch. The core returns false for nonpositive costs, and the optional must_pay flag is passed to the LP-cost check.

Parameters

• player int - Player checked for payment ability.
• cost int - LP amount to check; values of 0 or less return false.
• must_pay bool optional - Passed through to the core LP-cost check; scripts use true when the player must be able to pay that exact amount.

Returns

• bool|nil - True if the LP cost can be paid; false if it cannot or cost is nonpositive; nil if player is invalid.
