技能只消耗一半CP值，如何实现？

JasperCrazy

使用的是图书馆里这个：https://rpg.blue/thread-237131-1-1.html

想实现 “防御”只消耗一半CP值便可再次行动 这类效果。
顺便问一下能否实现 打退敌人的CP条，延迟其行动 的效果。

脚本如下：[pre lang="ruby" line="1" file="RTAB-CP"]#RTAB战斗系统 For RPG Maker VX Ace 编写者：SLICK

关于如何打退敌人的CP条，作为脚本盲想了个很野的办法：
开关[击退CP]关闭时，关闭脚本自带的造成伤害击退CP效果；
开关[击退CP]开启时，启用效果；
然后特定技能释放前后公共事件开关开关……
感觉局限性很大，希望各位大佬指正。

减少CP时间的话，改两句就行了。
首先是加一个initial_cp变量进去，改动的地方自己找。

7. 
   
8. class Game_Battler < Game_BattlerBase
   
9.   attr_accessor :turn_count
   
10.   attr_accessor :rtab_cp
    
11.   attr_accessor :initial_cp

22.     @cp_quota = 100
    
23.     @in_turn = false
    
24.     neoinitialize
    
25.   end
    
26.   #--------------------------------------------------------------------------

32.     update_state_turns
    
33.     update_buff_turns
    
34.     remove_states_auto(2)
    
35.     # 该角色的回合计数加1并清空CP
    
36.     @turn_count += 1
    
37.     @rtab_cp = @cp_quota * @initial_cp / 100
    
38.     @initial_cp = 0
    
39.   end
    
40. end

复制代码

然后从技能的备注栏读取CP恢复的百分比。

1. class RPG::Skill
   
2.   def skill_cp_supply
   
3.     /<CP_SUPPLY\s*(\d+)>/ =~ note ? $1.to_i : 0
   
4.   end
   
5. end

复制代码

在pay_skill_cost环节更改initila_cp

1. class Game_Actor
   
2.   alias neo_pay_skill_cost pay_skill_cost
   
3.   def pay_skill_cost(skill)
   
4.     neo_pay_skill_cost(skill)
   
5.     @initial_cp += skill.skill_cp_supply
   
6.   end
   
7. end

复制代码

至于打退CP条，不太清楚你想实现的是什么。开关的话，在他的那段代码那儿加个条件判断呗。

改QUOTA也行，视觉效果好些，有种越来越快的感觉。
