Version 1.4.4-fabric+1.21

Changlog

Function

This module mainly provides commands to implement.

Note: For some commands, if the executor is not a player object, you need to use execute to change the executor.
Considering that it is used by map creators, all commands only require level 2 permissions.

Game Rules

Entity damage interval mobDamageInvulnerable (default true)

If this game rule is changed, entities will no longer have a damage invulnerability interval.

Player damage interval playerDamageInvulnerable (default true)

If this game rule is changed, players will no longer have a damage invincibility interval.

The Pitch value of the display entity class DisplayEntity is no longer restricted by the original version ([-90F,90F]), you can change it at will!

Command /data can merge player data now

Player attribute

Multi-hop capability mapperplugin:player.multi_jump (default 1.0, minimum 1.0, maximum 6.0)

The player's multi-jump ability. If this option is changed, it will only take effect for integer types.

NBT tag

The player's mouse input will be monitored and stored in the own NBT (read-only).

example:

{Options: {attack:0, use:0, space:0, sneak:0}}

Int type represents: 0 key not pressed 1 key pressed 2 key held down 3 key released

#Example Command
execute as @a[nbt={Options:{attack:2,use:3}}] run say Press and hold the attack key and release the use key

For WitherEntity

Addon NBT Compound BossbarVisible ,Used to change whether the Wither entity displays the bossbar (default true)

DataComponent Item component

New Item component mapperplugin:attack_event mapperplugin:use_event

#When attacking entities with handheld objects, function tutorial:attack will be executed
give @s minecraft:diamond[mapperplugin:attack_event:{function:"tutorial:attack"}]

#When the main hand uses an item, function tutorial:use will be executed
give @s minecraft:diamond[mapperplugin:use_event:{function:"tutorial:use"}]
#When the off hand uses an item, function tutorial:use will be executed
give @s minecraft:diamond[mapperplugin:use_event:{function:"tutorial:use", main_hand:false}]

#Send Storage demo:test to named 'storageMethod' method then run
mp:gui send direct storageMethod demo:test
#JS
function storageMethod(nbt) {
    console.log(nbt);
}

For GUI developers

This function is based on the JCEF browser Chrome kernel. If you want to customize the GUI, you need certain basic knowledge of HTML.

JS interface:

// Correct implementation
// Close the GUI
window.cefQuery({
  request: "closeGUI",
  persistent: false,
});

// Call Minecraft command
function queryMinecraftCommand(str) {
  window.cefQuery({
    "request": "command:" + str,
    "persistent": false
  });

//Get a list of online players
    window.cefQuery({
        request: "playerList",
        persistent: false,
        onSuccess: function (response) {
            console.log(response)
        }
    });
}

// Please do not use this operation!
// Incorrect example, it will cause an infinite loop and occupy network communication

const cmd = 'mp:gui send direct queeryMinecraftCommand();';
function queryMinecraftCommand() {
    window.cefQuery({
        "request": "command:" + cmd,
        "persistent": false
    });
}
queryMinecraftCommand();

If the client cannot respond to JS requests when calling the GUI, try entering the /mp: reconfig_cef command to reconfigure.

mp:hud

This command is used to customize the drawing of HUD.

This mod provides the ability to customize the drawing of HUD through JSON files (how to write custom data files will be introduced later). You only need to place the prepared files in the corresponding location and then call them.

HUD data files will be loaded in the data pack data/<namespace>/hud/.

Usage:

mp:hud add <Path>
mp:hud clear [<Path>]
mp:hud send <Path> <Argument>

add <Path: path>: The HUD configuration file to be loaded.

clear [<Path: path>]: The HUD file to be cleared. If not specified, all loaded HUD configuration files will be cleared.

send <Path: path> <Argument: nbt>: The information to be sent to the target HUD (refer to function ... with).

#Example command
#Assuming there is a data pack templete data/namespace/hud/abc.json
mp:hud add namespace:abc

Below is how to customize the HUD file:

// This contains an HUD file, the entire content is LayerDraw
{
  "name": "Example HUD", // File name, required
  "version": "1.2.1",    // File version, required
  "component": [         // Contains one or more rendering layer components, required
    LayerDrawComponent1...,
    LayerDrawComponent2...,
    LayerDrawComponent3...,
    LayerDrawComponent4...,
    ...
  ],
  "resource": [          // Contains one or more texture resources, preset resources will be used during rendering, optional
    TextureResource1...,
    TextureResource2...,
    TextureResource3...,
    TextureResource4...,
    ...
  ],
  "replacement": {       // Default text that can be changed during initialization, such as $(key1) being displayed as value1 after initialization
    "key1": "value1",
    "key2": "value2",
    "key3": "value3",
    "name": "@s"         // If the changeable text is @s, the player's original name is returned
  }
}

// Texture resource data format, the entire content is TextureResource
{

<Sound: path>: Specify the sound event to be played, which is the same as the original version

<SoundCategory: sound_category>: Specify the category to which the playback sound belongs, corresponding to the category set in the "Music and Sound" option of the game, which is the same as the original version

static: Specify to play as static sound, such as background music in games

stereo <Pos: x y z> <UseDistance: boolean>: Specify the playback as stereo sound, such as a note box, which requires filling in coordinates and whether it is affected by distance volume attenuation (note: the audio needs to support stereo sound, otherwise it is no different from static sound)

[<Volume: float>] [<Pitch: float>] [<Repeat: boolean>] [<RepeatDelay: int>]: Volume when playing sound (default 1.0F), pitch size (default 1.0F), whether to play repeatedly (default false), and the interval between repetitions (default 0)

mp:schedule

This directive provides more powerful scheduling capabilities than the vanilla schedule command. It allows attaching command execution sources and uses command blocks for more efficient task execution.

Additionally, it supports persistent data that won't disappear due to game cycle updates.

Usage:

mp:schedule <Name: string> <Time: int> (append | replace | loop) <CommandBlock: command_block>

<Name: string>: The name of the scheduled task. To clear a task, use /schedule clear mapperplugin:<Name>.
<Time: int>: The delay time in ticks.
(append | replace | loop): Specifies how to handle existing schedules:
- append: Add a new schedule.
- replace: Replace existing schedules.
- loop: Repeat the schedule indefinitely.
<CommandBlock: command_block>: A command block parameter.

#Command Block Format

#Commands are combined using `{}` and `;`:
execute as @n[type=minecraft:pig] run mp:schedule demo 10t append { say 1; say 2; }
This will execute 'say 1' and 'say 2' after 10 ticks, with @n[type=minecraft:pig] as the executor.

#你也可以在命令块内嵌套多个命令块，如：
mp:schedule demo 10t append { say 1; say 2; mp:schedule demo1 10t append { say 3; say 4; mp:schedule demo2 10t append { say 5; say 6; }; }; say happy;}
#Execution Order:
#---10t---
say 1
say 2
say happy
#---20t---
say 3
say 4
#---30t---
say 5
say 6

#Line breaks inside command blocks do not require \ (only within command blocks):
demo.mcfunction
tellraw @a ["begin"]
mp:schedule demo 10t append {
    say 1;
    say 2;
    mp:schedule demo1 10t append {
        say 3;
        say 4;
    };
}
tellraw @a ["middle \
"]
tellraw @a ["end"]

#Important Notes:：Avoid using special characters {, }, or ; inside command blocks unless properly enclosed.
#Invalid Example:
mp:schedule error 10t append {
        say >>{ DEMO;
        say this;that;
    };
#Error:
?Unclosed brackets: say >>{ DEMO
?Unkown command: that

Use the vanilla schedule clear command with the mapperplugin:<Name> identifier:

#Assuming you have executed the following command:
mp:schedule demo_loop 10t loop {say 1;}

# To clear a looped schedule:
schedule clear mapperplugin:demo_loop
