RPG Maker VX Ace中的RGSS-

Question

我一直在爲RPG Maker VX Ace使用一組腳本，紋理和音頻，稱爲Pokémonfor Ace。我一直在成功解決一些錯誤，但是這個我無法修復。 我得到這個錯誤在控制檯：

Item Effects:216:in `block in extra_evs': private method `extra_evs' called for nil:NilClass (NoMethodError) 
    from Item Effects:216:in `each' 
    from Item Effects:216:in `inject' 
    from Item Effects:216:in `extra_evs' 
    from Pokémon Battle System:4403:in `block (3 levels) in process_action_end' 
    from Pokémon Battle System:4392:in `each' 
    from Pokémon Battle System:4392:in `block (2 levels) in process_action_end' 
    from Pokémon Battle System:4379:in `each' 
    from Pokémon Battle System:4379:in `block in process_action_end' 
    from Pokémon Battle System:4373:in `each' 
    from Pokémon Battle System:4373:in `process_action_end' 
    from Mega Evolution:453:in `process_action' 
    from Scene_Battle:48:in `update' 
    from Pokedex:1746:in `update' 
    from Party Dying Battle BGM:130:in `update' 
    from Scene_Base:14:in `main' 
    from MOG_Weather_EX:694:in `main' 
    from Graphical Object Global Reference:201:in `main' 
    from Video Player:153:in `run' 
    from Map Screenshot:971:in `run' 
    from Screenshot taker:215:in `run' 
    from Main:12:in `block in <main>' 

這裏的，讓錯誤的部分代碼：

class Game_Battler < Game_BattlerBase 
    attr_accessor :attacking_item 
    attr_accessor :captured 
    def extra_evs(stat) 
     equips.inject(0) {|r, equip| r += equip.extra_evs(stat)} 
    end 

Answer 1

你equips數組包含一個零值。檢查它被分配的位置。

對於髒修復，請嘗試equips.compact.inject(0) {|r, equip| r += equip.extra_evs(stat)}
