Required Plugins

The following plugins are required in order to use this plugin.

Place the following plugins above this plugin located in the Plugin Manager.

Yanfly Engine Plugins

This plugin is a part of the Yanfly Engine Plugins library.


This plugin requires YEP_BattleEngineCore. Make sure this plugin is located
under YEP_BattleEngineCore in the plugin list.

To use the STB system, go to the Battle Engine Core plugin and change the
'Default System' setting in the parameters to 'stb'.

The Standard Turn Battle system functions off of the Default Turn Battle
system's structure. Action orders are determined by the battlers' AGI values
and they go from highest to lowest. However, actions are not selected at the
start of the turn. Instead, the turn progresses and the actions are picked
as each battler's turn appears, then proceeds to be executed immediately.

Each battler is only allowed one action per battle turn, meaning a single
battler cannot have twice the number of turns as another battler even if the
battler's AGI value is double that of the other. This is to prevent any
balancing issues that come from tick-based battle systems as they tend to be
far more difficult to balance compared to turn-based battle systems.

Because of the nature of the Standard Turn Battle System, an item or skill's
action speed value found in the database will be disabled as it cannot push
forward a battler's in the turn order.

Plugin Commands


Plugin Commands are event commands that are used to call upon functions added by a plugin that aren't inherently a part of RPG Maker MV.

Here is a list of Plugin Command(s) that you may use:

To change your battle system to Standard Turn Battle if it isn't the default
battle system, you can use the following Plugin Command:

Plugin Command:
  setBattleSys STB      Sets battle system to Standard Turn Battle.
  setBattleSys DTB      Sets battle system to Default Turn Battle.

Using the above Plugin Commands, you can toggle between the Default Battle
System and Standard Turn Battle!



RPG Maker MV's editor is unable to allow for custom traits/properties that a game dev may wish to associate with a database object, event, map, etc. Notetags are used to work around such limitations by allowing the game dev to tag certain traits/properties using specific Notetags declared by the related plugin.

Here is a list of Notetag(s) that you may use.


The following are notetags that pertain to and affect the STB system.

Skill and Item Notetags:

  <STB Help>
  </STB Help>
  For those planning on using multiple battle systems, sometimes you may
  have your skills perform differently while using STB. If so, using this
  notetag will allow skills and items to display different help text while
  STB is enabled.
