# MCPyLib - Python Client Library

Python client library for controlling Minecraft servers remotely.

## Installation

Install MCPyLib using pip:

```bash
pip install mcpylib
```

Or using uv (faster alternative):

```bash
uv pip install mcpylib
```

<details>
<summary><b>Want faster package management? Try uv!</b></summary>

[uv](https://github.com/astral-sh/uv) is a blazing-fast Python package manager (10-100x faster than pip).

### Install uv

```bash
# On macOS/Linux
curl -LsSf https://astral.sh/uv/install.sh | sh

# On macOS with Homebrew
brew install uv

# On Windows
powershell -c "irm https://astral.sh/uv/install.ps1 | iex"
```

### Install MCPyLib with uv

```bash
uv pip install mcpylib
```

### Run scripts with uv

```bash
uv run python your_script.py
```

### Why use uv?

- **Fast**: 10-100x faster than pip
- **Reliable**: Automatic dependency locking
- **Simple**: One command to set up everything
- **Isolated**: Automatic virtual environment management

</details>

## Quick Start

### Create and run your first script

```python
# quickstart.py
from mcpylib import MCPyLib

# Initialize client
mc = MCPyLib(
    ip="127.0.0.1",      # Server IP
    port=65535,          # Server port
    token="your_token"   # Authentication token
)

# Set a diamond block
mc.setblock(100, 64, 200, "minecraft:diamond_block")

# Get block type
block = mc.getblock(100, 64, 200)
print(f"Block: {block}")  # Output: Block: minecraft:diamond_block

# Fill a 10x10x10 region with glass
count = mc.fill(0, 60, 0, 10, 70, 10, "minecraft:glass")
print(f"Filled {count} blocks")

# Get player position
pos = mc.getPos("Steve")
print(f"Player at: {pos}")  # Output: Player at: [100, 64, 200]
```

### Run the script

```bash
# With uv (recommended)
uv run python quickstart.py

# Or with pip
python quickstart.py
```

##### edit()

```python

```

High-performance bulk block editing (like WorldEdit). Place large structures with mixed block types in a single operation.

**Parameters:**

    ```python
    {
        "block": "minecraft:chest",
        "block_state": {"facing": "north"},  # Optional
        "nbt": {"CustomName": '{"text":"Storage"}'}  # Optional
    }
    ```

**Returns:**
- Number of blocks placed

**Raises:**
- `ConnectionError`: Failed to connect to server
- `AuthenticationError`: Invalid token
- `CommandError`: Invalid block data or coordinates

**Example:**
```python
# Simple 2x2x2 cube
blocks = [
    [["stone", "glass"], ["stone", "glass"]],
    [["stone", "glass"], ["stone", "glass"]]
]
mc.edit(100, 64, 200, blocks)

# Mixed mode with complex blocks
blocks = [
    [[None, "stone"], ["glass", None]],
    [[{
        "block": "minecraft:chest",
        "block_state": {"facing": "north"},
        "nbt": {"CustomName": '{"text":"Loot"}'}
    }, "stone"], ["diamond_block", "gold_block"]]
]
mc.edit(100, 64, 200, blocks)

# Build a house
blocks = []
for x in range(10):
    x_layer = []
    for y in range(5):
        y_layer = [None] * 10
        x_layer.append(y_layer)
    blocks.append(x_layer)

# Floor
for x in range(10):
    for z in range(10):
        blocks[x][0][z] = "stone"

# Walls
for y in range(1, 4):
    for x in range(10):
        blocks[x][y][0] = "cobblestone"
        blocks[x][y][9] = "cobblestone"
    for z in range(10):
        blocks[0][y][z] = "cobblestone"
        blocks[9][y][z] = "cobblestone"

# Roof
for x in range(10):
    for z in range(10):
        blocks[x][4][z] = "oak_planks"

count = mc.edit(100, 64, 200, blocks)
print(f"House built: {count} blocks")
```

**Performance Notes:**
- Use `edit()` for structures with multiple different block types
- Use `fill()` for large areas of the same block
- Much faster than calling `setblock()` repeatedly
- Supports thousands of blocks in a single operation

##### clone()

```python
clone(x1: int, y1: int, z1: int, x2: int, y2: int, z2: int, dest_x: int, dest_y: int, dest_z: int) -> int
```

Clone a region of blocks to a new location.

**Parameters:**
- `x1`, `y1`, `z1` (int): Source region start coordinates
- `x2`, `y2`, `z2` (int): Source region end coordinates
- `dest_x`, `dest_y`, `dest_z` (int): Destination coordinates

**Returns:**
- Number of blocks cloned

**Raises:**
- `ConnectionError`: Failed to connect to server
- `AuthenticationError`: Invalid token
- `CommandError`: Region too large (max 32,768 blocks)

**Example:**
```python
# Clone a 10x10x10 region
count = mc.clone(0, 64, 0, 10, 74, 10, 20, 64, 0)
print(f"Cloned {count} blocks")

# Copy a house from one location to another
mc.clone(100, 64, 100, 110, 74, 110, 200, 64, 200)
```

## Exception Handling

MCPyLib defines custom exceptions:

```python
from mcpylib import MCPyLib, MCPyLibError, ConnectionError, AuthenticationError, CommandError

try:
    mc = MCPyLib(token="wrong_token")
    mc.setblock(100, 64, 200, "minecraft:stone")
except AuthenticationError as e:
    print(f"Authentication failed: {e}")
except ConnectionError as e:
    print(f"Connection failed: {e}")
except CommandError as e:
    print(f"Command failed: {e}")
except MCPyLibError as e:
    print(f"General error: {e}")
```

## Block Names

Block names can be specified with or without the "minecraft:" namespace prefix:

```python
# Both are valid
mc.setblock(0, 64, 0, "minecraft:stone")
mc.setblock(0, 64, 0, "stone")

# Common blocks
mc.setblock(0, 64, 0, "grass_block")
mc.setblock(0, 65, 0, "oak_log")
mc.setblock(0, 66, 0, "diamond_block")
mc.setblock(0, 67, 0, "glowstone")
```

See the [Minecraft Wiki](https://minecraft.fandom.com/wiki/Java_Edition_data_values) for a complete list of block IDs.

## Advanced Usage

### Custom Timeout

```python
# Set a longer timeout for slow connections
mc = MCPyLib(
    ip="192.168.1.100",
    port=65535,
    token="your_token",
    timeout=30.0  # 30 seconds
)
```

### Building Structures

```python
def build_cube(mc, x, y, z, size, block):
    """Build a hollow cube"""
    # Bottom and top
    mc.fill(x, y, z, x+size, y, z+size, block)
    mc.fill(x, y+size, z, x+size, y+size, z+size, block)

    # Sides
    mc.fill(x, y, z, x, y+size, z+size, block)
    mc.fill(x+size, y, z, x+size, y+size, z+size, block)
    mc.fill(x, y, z, x+size, y+size, z, block)
    mc.fill(x, y, z+size, x+size, y+size, z+size, block)

# Build a 10x10x10 glass cube
build_cube(mc, 0, 64, 0, 10, "glass")
```

### Following Players

```python
import time

def follow_player(mc, username, interval=1.0):
    """Track player movement"""
    try:
        while True:
            pos = mc.getPos(username)
            print(f"{username} is at {pos}")
            time.sleep(interval)
    except KeyboardInterrupt:
        print("Stopped tracking")
    except CommandError as e:
        print(f"Error: {e}")

follow_player(mc, "Steve")
```
