$imported["YEA-RandomSkillInvoke"] = true

#==============================================================================
# ▼ Updates
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# 2011.12.17 - Started Script and Finished.
#
#==============================================================================
# ▼ Introduction
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# This script grants the option, that when designated skills with random
# invokes are used, they have the ability to result in other skills (within the
# skill's designated random pool). Only valid skills are capable of being used
# (meaning that they must meet the conditions to be used).
#
#==============================================================================
# ▼ Instructions
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# To install this script, open up your script editor and copy/paste this script
# to an open slot below ▼ Materials/素材 but above ▼ Main. Remember to save.
#
# -----------------------------------------------------------------------------
# Skill Notetags - These notetags go in the skills notebox in the database.
# -----------------------------------------------------------------------------
# <random invoke: x>
# <random invoke: x, x>
# This adds skill x to the random invoke pool (which includes the base skill
# itself, too). When the base skill is used, it will random select from all of
# the skills within the random invoke pool and use one. Only skills that meet
# the requirements of being used can be selected (meaning the battler must have
# sufficient MP costs, TP costs, no states that seal it, etc.). Multiples of
# this tag may be used to add more skills, and multiples of the same skill may
# be added to the random invoke pool.
#
#==============================================================================
# ▼ Compatibility
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# This script is made strictly for RPG Maker VX Ace. It is highly unlikely that
# it will run with RPG Maker VX without adjusting.
#
#==============================================================================
# ▼ Editting anything past this point may potentially result in causing
# computer damage, incontinence, explosion of user's head, coma, death, and/or
# halitosis so edit at your own risk.

76.随即技能系统（来自Yanfly Engine Ace）
使用此脚本可以在角色在战斗中使用过一个技能后继续释放你所设置的随即一个技能。比如，我们设置了一个技能，在此备注中设置了（X，Y为技能编号），那么，使用了这个技能后，系统会自动随机选取x,y其中一个技能来释放。大概就是这个意思了。

是我哪里设置错了吗 用技能的时候不随机出30 31编号技能
