||||
## Latest Update - Box Physics & Combat System
|
||||
|
||||
### ✨ New Features
|
||||
|
||||
#### 1. **Z-Axis Physics for Boxes**
|
||||
- Boxes now fly in realistic arcs when thrown (just like players)
|
||||
- Added `position_z`, `velocity_z`, `gravity_z` simulation
|
||||
- Visual feedback with sprite offset and scaling based on height
|
||||
- Smooth landing animation with squash-and-stretch effect
|
||||
|
||||
#### 2. **Dynamic Shadow System**
|
||||
- Added shadow sprites to both players and boxes
|
||||
- Shadows scale down and fade as objects get higher
|
||||
- Real-time shadow updates based on Z-position
|
||||
- Helps visualize height in the 2D top-down view
|
||||
|
||||
#### 3. **Box Breaking Mechanic**
|
||||
- Boxes shatter into 4 smaller pieces on impact
|
||||
- Pieces fly outward in random directions
|
||||
- Fade out animation before disappearing
|
||||
- Triggered when hitting players or other boxes mid-air
|
||||
|
||||
#### 4. **Combat System**
|
||||
- Players take 10 damage when hit by thrown boxes
|
||||
- Knockback effect pushes players away from impact
|
||||
- Flash red visual feedback on damage
|
||||
- Health system with respawn at origin on death
|
||||
- Damage synced across network
|
||||
|
||||
#### 5. **Mid-Air Collision Detection**
|
||||
- Boxes detect collisions while airborne
|
||||
- Separate handling for player vs box collisions
|
||||
- Chain reactions: thrown box breaks target box too
|
||||
- Network-synchronized breaking effects
|
||||
|
||||
### 🔧 Technical Improvements
|
||||
|
||||
#### CharacterBody2D Migration
|
||||
- Converted boxes from RigidBody2D to CharacterBody2D
|
||||
- Deterministic physics for better network sync
|
||||
- Direct velocity control instead of forces/impulses
|
||||
- Eliminated non-deterministic physics simulation issues
|
||||
|
||||
#### Helper Functions
|
||||
- Added `_is_box()` and `_is_player()` helper functions
|
||||
- Simplified collision detection logic
|
||||
- Easier to maintain and extend
|
||||
|
||||
#### Network Synchronization
|
||||
- Added `_sync_damage()` RPC for player damage
|
||||
- All breaking effects visible on all clients
|
||||
- Proper authority checks for damage dealing
|
||||
|
||||
### 🎨 Visual Enhancements

||||
### Windows
|
||||
|
||||
**Option 1: Use the Batch Script**
|
||||
```bash
|
||||
# Edit TEST_MULTIPLAYER.bat and set your Godot path
|
||||
# Then just double-click it or run:
|
||||
TEST_MULTIPLAYER.bat
|
||||
```
|
||||
|
||||
**Option 2: Manual Command**
|
||||
```bash
|
||||
# Terminal 1 (Host)
|
||||
"C:\Program Files\Godot\godot.exe" --path "C:\dev\godot\multiplayer-coop" -- --host
|
||||
|
||||
# Terminal 2 (Client 1)
|
||||
"C:\Program Files\Godot\godot.exe" --path "C:\dev\godot\multiplayer-coop" -- --join
|
||||
|
||||
# Terminal 3 (Client 2)
|
||||
"C:\Program Files\Godot\godot.exe" --path "C:\dev\godot\multiplayer-coop" -- --join
|
||||
```
|
||||
|
||||
### Linux/Mac
|
||||
|
||||
**Option 1: Use the Shell Script**
|
||||
```bash
|
||||
# Make it executable (already done)
|
||||
chmod +x TEST_MULTIPLAYER.sh
|
||||
|
||||
# Run it
|
||||
./TEST_MULTIPLAYER.sh
|
||||
```
|
||||
|
||||
**Option 2: Manual Command**
|
||||
```bash
|
||||
# Terminal 1 (Host)
|
||||
godot --path "$(pwd)" -- --host
|
||||
|
||||
# Terminal 2 (Client 1)
|
||||
godot --path "$(pwd)" -- --join
|
||||
|
||||
# Terminal 3 (Client 2)
|
||||
godot --path "$(pwd)" -- --join
|
||||
```
|
||||
|
||||
## Command-Line Arguments
|
||||
|
||||
### Basic Arguments
|
||||
|
||||
- `--host` - Automatically start as host
|
||||
- `--join` - Automatically join game
|
||||
- `--address=IP` - Server address (default: 127.0.0.1)
|
||||
- `--players=N` - Number of local players (default: 1)
|
||||
|
||||
### Examples
|
||||
|
||||
**Host with 2 local players:**
|
||||
```bash
|
||||
godot --path "path/to/project" -- --host --players=2
|
||||
```
|
||||
|
||||
**Join specific server with 1 player:**
|
||||
```bash
|
||||
godot --path "path/to/project" -- --join --address=192.168.1.100
|
||||
```
|
||||
|
||||
**Join with 3 local players:**
|
||||
```bash
|
||||
godot --path "path/to/project" -- --join --players=3
|
||||
```
|
||||
|
||||
## Testing Scenarios
|
||||
|
||||
### Scenario 1: Simple 1v1
|
||||
```bash
|
||||
# Instance 1
|
||||
godot -- --host
|
||||
|
||||
# Instance 2
|
||||
godot -- --join
|
||||
```
|
||||
|
||||
### Scenario 2: 1 Host + 2 Clients
|
||||
```bash
|
||||
# Instance 1
|
||||
godot -- --host
|
||||
|
||||
# Instance 2
|
||||
godot -- --join
|
||||
|
||||
# Instance 3
|
||||
godot -- --join
|
||||
```
|
||||
|
||||
### Scenario 3: Multiple Local Players
|
||||
```bash
|
||||
# Instance 1 (host with 2 local players)
|
||||
godot -- --host --players=2
|
||||
|
||||
# Instance 2 (client with 2 local players)
|
||||
godot -- --join --players=2
|
||||
```
|
||||
|
||||
### Scenario 4: Maximum Chaos
|
||||
```bash
|
||||
# Instance 1 (host with 4 local players)
|
||||
godot -- --host --players=4
|
||||
|
||||
# Instance 2-7 (each with 4 local players)
|
||||
godot -- --join --players=4
|
||||
```
|
||||
Result: 8 machines × 4 local players = 32 total players!
|
||||
|
||||
## From Godot Editor
|
||||
|
||||
You can also test from the editor:
|
||||
|
||||
1. **Run the main instance from editor:**
|
||||
- Just press F5 normally
|
||||
- Host or join manually from the menu
|
||||
|
||||
2. **Run additional instances:**
|
||||
```bash
|
||||
# From terminal, run additional instances
|
||||
godot --path "C:\dev\godot\multiplayer-coop" -- --join
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### "Connection Failed"
|
||||
- Make sure host is running first
|
||||
- Wait 1-2 seconds after starting host
|
||||
- Check firewall settings
|
||||
|
||||
### "Can't find godot.exe"
|
||||
- Edit the .bat or .sh script
|
||||
- Set the correct path to your Godot executable
|
||||
- On Linux/Mac, make sure `godot` is in your PATH
|
||||
|
||||
### "Players not spawning"
|
||||
- Check the console/Output tab for errors
|
||||
- Verify NetworkManager is loaded
|
||||
- Make sure you're using matching project versions
|
||||
|
||||
### "Script won't run"
|
||||
- Windows: Right-click .bat → Run as Administrator
|
||||
- Linux/Mac: Make sure it's executable (`chmod +x TEST_MULTIPLAYER.sh`)
|
||||
|
||||
## What You Should See
|
||||
|
||||
### When Testing Works:
|
||||
1. **Host window** opens, immediately shows game world
|
||||
2. **Client 1** opens, connects, spawns in game world
|
||||
3. **Client 2** opens, connects, spawns in game world
|
||||
4. All players visible to each other
|
||||
5. All players can move and interact
|
||||
|
||||
### Debugging
|
||||
- Press **ESC** in any instance to see debug overlay
|
||||
- Shows network status, peer ID, player counts

||||
2. Move players around
|
||||
3. Grab objects
|
||||
4. Throw objects
|
||||
5. Verify smooth sync (no jittering)
|
||||
|
||||
### Test Stress
|
||||
1. Start multiple instances
|
||||
2. Add many local players
|
||||
3. Spawn many objects
|
||||
4. Test with rapid interactions
|
||||
5. Monitor FPS (press ESC for debug)
|

# Windows: Create restart.bat
|
||||
@echo off
|
||||
taskkill /F /IM godot.exe
|
||||
timeout /t 1 /nobreak
|
||||
call TEST_MULTIPLAYER.bat
|
||||
```
|
||||
|
||||
### Different Configurations
|
||||
```bash
|
||||
# Test different player counts
|
||||
godot -- --host --players=1
|
||||
godot -- --join --players=2
|
||||
godot -- --join --players=3
|
||||
godot -- --join --players=4
|
||||
```
|
||||
|
||||
### Network Testing
|
||||
```bash
|
||||
# Test over network (replace IP with actual host IP)
|
||||
godot -- --host # On machine 1
|
||||
godot -- --join --address=192.168.1.100 # On machine 2
|
||||
```
|
||||
|
||||
## CI/CD Testing
|
||||
|
||||
You can integrate these commands into automated testing:
|
||||
|
||||
```bash
|
||||
# Start host in background
|
||||
godot --path "$PROJECT" -- --host &
|
||||
HOST_PID=$!
|

|
||||
|
||||
## How It Works
|
||||
|
||||
### Multiplayer Architecture
|
||||
|
||||
**Host Flow**:
|
||||
1. Player clicks "Host Game"
|
||||
2. ENet server created on port 7777
|
||||
3. Host registers as first player
|
||||
4. Waits for clients to connect
|
||||
|
||||
**Client Flow**:
|
||||
1. Player enters host IP and clicks "Join"
|
||||
2. ENet client connects to host
|
||||
3. Sends player info to server
|
||||
4. Receives full game state
|
||||
|
||||
**Player Spawning**:
|
||||
1. Each peer reports local player count
|
||||
2. Server spawns all players
|
||||
3. Server syncs spawn to all clients
|
||||
4. Authority assigned to owning peer
|
||||
|
||||
### Local Multiplayer
|
||||
|
||||
**Input Distribution**:
|
||||
- Player 1: Keyboard (WASD + E/Q)
|
||||
- Player 2: Gamepad 0 (Left Stick + A/B)
|
||||
- Player 3: Gamepad 1 (Left Stick + A/B)
|
||||
- Player 4: Gamepad 2 (Left Stick + A/B)
|
||||
|
||||
**Camera Handling**:
|
||||
- Calculates center of all local players
|
||||
- Smoothly follows center point
|
||||
- Adjusts zoom to keep all visible
|
||||
- Independent per machine
|
||||
|
||||
### Interaction Mechanics
|
||||
|
||||
**Grab**:
|
||||
1. Press E (keyboard) or A (gamepad)
|
||||
2. Detect objects within 80 units
|
||||
3. Grab closest object
|
||||
4. Object follows player with offset
|
||||
|
||||
**Throw**:
|
||||
1. Press Q (keyboard) or B (gamepad)
|
||||
2. Calculate direction from movement
|
||||
3. Apply force based on weight
|
||||
4. Release object with velocity
|
||||
|
||||
**Push**:
|
||||
1. Walk into object
|
||||
2. Physics engine handles collision
|
||||
3. Force transfers naturally
|
||||
4. Heavier objects resist more
|
||||
|
||||

### 📋 Manual Testing Required
|
||||
|
||||
Due to the nature of multiplayer games, the following require manual testing:
|
||||
|
||||
1. **Network Latency**: Test over real network (not just localhost)
|
||||
2. **Multiple Clients**: Test with 2+ remote clients
|
||||
3. **Drop-in**: Join game mid-session
|
||||
4. **Disconnect Handling**: Client drops during gameplay
|
||||
5. **Edge Cases**: Rapid actions, boundary testing, etc.
|
||||
|
||||
See `TESTING.md` for comprehensive test checklist.
|
||||
|
||||
## Performance Characteristics
|
||||
|
||||
### Network
|
||||
- **Bandwidth**: ~5-10 KB/s per player (position updates)
|
||||
- **Latency**: < 100ms on LAN, varies on internet
|
||||
- **Tick Rate**: 60 Hz (every physics frame)
|
||||
- **Protocol**: ENet (reliable UDP)
|
||||
|
||||
### Physics

||||
- **Collision Layers**: 3 layers (players, objects, walls)
|
||||
- **Rigid Bodies**: 5 objects + dynamic players
|
||||
- **Physics FPS**: 60 (Godot default)
|
||||
- **Optimization**: Object sleeping when stationary
|
||||
|
||||
### Rendering
|
||||
- **Draw Calls**: Minimal (simple sprites)
|
||||
- **Target FPS**: 60
|
||||
- **Resolution**: Scalable
|
||||
- **Camera**: Single camera per client
|
||||
|
||||
## Scalability
|
||||
|
||||
### Current Limits
|
||||
- **Max Connections**: 8 peers
|
||||
- **Max Local Players**: 4 per machine
|
||||
- **Max Total Players**: 32 (8 peers × 4 local)
|
||||
- **Map Size**: 2000×2000 units
|
||||
- **Objects**: ~50 before performance impact
|
||||
|
||||
### Bottlenecks
|
||||
1. **Network**: Position sync for all players
|
||||
2. **Physics**: Many rigid bodies interacting
|
||||
3. **Input**: Limited gamepad support (4)
|
||||
4. **Camera**: Single view per client
|
||||
|
||||
### Optimization Opportunities
|
||||
- Object pooling for spawned items
|
||||
- Spatial partitioning for large maps
|
||||
- Interest management for distant players
|
||||
- Client-side prediction for smoother movement
|
||||
|
||||

|
||||
|
||||
**New Interactable Objects**:
|
||||
1. Create a scene inheriting from `interactable_object.tscn`
|
||||
2. Adjust the sprite, collision shape, and mass
|
||||
3. Optionally override interaction methods
|
||||
|
||||
**Custom Player Abilities**:
|
||||
1. Add new input actions in Project Settings
|
||||
2. Implement ability logic in `player.gd`
|
||||
3. Add network synchronization if needed
|
||||
|
||||
**New Game Modes**:
|
||||
1. Create a new scene inheriting from `game_world.tscn`
|
||||
2. Add game mode logic in a new script
|
||||
3. Update the main menu to select game modes
|
||||
|
||||
### Testing Multiplayer
|
||||
|
||||
**Local Testing**:
|
||||
1. Run the game from Godot editor
|
||||
2. Click "Host Game"
|
||||
3. Run a second instance from the exported build
|
||||
4. Enter "127.0.0.1" and click "Join Game"
|
||||
|
||||
**Network Testing**:
|
||||
1. Host on one machine
|
||||
2. Find the host's local IP address (ipconfig/ifconfig)
|
||||
3. Join from another machine on the same network
|
||||
4. For internet play, configure port forwarding on port 7777
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
**Connection Failed**:
|
||||
- Verify the IP address is correct
|
||||
- Check firewall settings (allow port 7777)
|
||||
- Ensure both machines are on the same network (for LAN play)
|
||||
|
||||
**Players Not Spawning**:
|
||||
- Check the console for errors
|
||||
- Verify the player scene is assigned in PlayerManager
|
||||
- Ensure NetworkManager is loaded as an autoload
|
||||
|
||||
**Gamepad Not Working**:
|
||||
- Connect gamepad before starting the game
|
||||
- Check gamepad is recognized in Godot's input settings
|
||||
- Verify you have more than 1 local player selected
|
||||
|
||||
**Objects Not Grabbable**:
|
||||
- Ensure object has `can_be_grabbed()` method
|
||||
- Check GrabArea collision layers/masks
|
||||
- Verify object is within grab range (80 units)
|
||||
|
||||
