PreventBuild

Adds control to prevent the player from performing certain actions that are set in configs. Configs, in turn, have a very flexible structure that allows you to build complex logical conditions describing what actions the mod should prevent.

Original purpose of creating this mod was enhancing experience of hand-building map-arts without using any printers and easy-place mode. But now it's more than just preventing placing and breaking: you can prevent any right- or left-click actions, just make sure there is a suitable condition.

This mod is just cancelling the player's actions, so it's fully client-side.

How to use the mod

It's almost necessary to visit the Wiki to understand how to write a config, because there is no other way to write it except by hand.

There are a few files in config/preventbuild/:

• conditions/ - contains config .cfg files
• condition_configs.json - defines which configurations are active by its individual name
• ore_dictionaries.json - defines custom ore dictionary lists for using in configs

Once you have created/updated your configs, you should update configs in the game using commands. Also configs are updating automatically when the player joins a world.

(For developers) Also you can find out how to create and register your own conditions that you will be able to use in the same config files.

Commands

• /pb config list - display a list of configs with their status
• /pb config switch - enable/disable config by name
• /pb config update - reload all configs

Server restrictions of the conditions

Since I'm trying to keep gameplay fair and rules-friendly, I decided to give server owners the ability to restrict
some conditions that they can consider as "cheating-like" actions.

For now, there's only a few of such restrictions. To use them, you need to add the following strings to the plugin
message via the "preventbuild:restrictions" channel and send it to players on PlayerRegisterChannelEvent:

NoItemDamage - Disables all the "Item Damage" and "Item Durability" conditions

NoBlockState - Disables the "Block State" condition

NoAgeBlockState - Disables only the use of the "age" state in the "Block State" condition

ResetAll - Resets all restrictions

Example:

@EventHandler
public void onRegisterChannelJoin(PlayerRegisterChannelEvent event) {
    if (event.getChannel().equals("preventbuild:restrictions")) {
        Player player = event.getPlayer();
        ByteArrayDataOutput out = ByteStreams.newDataOutput();
        out.writeUTF("NoItemDamage NoAgeState");
        player.sendPluginMessage(this, event.getChannel(), out.toByteArray());
    }
}

Note

Well, this is my first relatively serious mod and especially the first one for public use. Thanks for visiting :)
