Battle rules are restrictions that can be placed on a battle. They are negotiated and selected prior to the battle, and remain in place throughout the battle. Both player-vs.-player and player-vs.-NPC Trainer battles can have battle rules configured. Battle rules can also be exported and imported as plain text to save rule configurations for later use.
If battle rules are configured, players will be taken to a "team selection" screen prior to battle, where they can choose which of their party Pokémon will be used during the battle, along with which Pokémon will be sent out first as the battle begins. Pokémon that are not selected for battle will become temporarily unavailable during battle, and will return after the battle is finished.
When challenging a player, one of the options in the challenge screen is the battle rules selection. If either player selects this option, the battle rules screen will open prior to the battle starting.
From the battle rules screen, the first player to select the battle rules option will be able to configure the rules for the battle. After this, the other player will be presented with the selected rules, and can confirm that the selected rules are satisfactory and start the battle.
If the second player is not satisfied with the rules, the rules can be modified by the second player and sent to the first player for confirmation. This process can continue until both players are satisfied with the rules, or until one player declines the battle completely. The Minecraft chat is available while selecting rules, allowing conversations to negotiate the rules.
List of rules
- Level cap: Imposes an upper limit on the level that Pokémon can be. Pokémon with levels higher than this limit have their levels reduced to the limit.
- Raise to cap: Pokémon with levels lower than the level cap have their levels raised to the level cap.
- Full heal: Pokémon will be fully healed, including HP, PP, and status, when the battle begins. After the battle is over, all of these attributes will revert back to what they were before the battle. This setting will also cause held items to be restored after the battle, regardless of the "returnHeldItems" config setting.
- Battle type: Whether the battle is a single battle (1 vs. 1) or a double battle (2 vs. 2). It is currently impossible to initiate multi battles with this setting.
- # Pokémon: The maximum number of Pokémon that can be selected for battle by each player.
- Turn time: The amount of time that players are given to select a move for a turn. If the timer expires, a move is selected randomly for the player.
- Team select time: The amount of time that players are given to select Pokémon before battle. If the timer expires, the currently selected Pokémon will be used for battle. If no Pokémon are selected, or all selected Pokémon cannot be used due to battle clause restrictions, the first eligible Pokémon will be automatically selected for battle.
- Team preview: If enabled, the Pokémon in the opposing team will be displayed during team selection.
