## 🚨 Critical Rules

**MUST READ BEFORE GENERATING ANY SCRIPT**

### ⚡ 脚本语法关键规则（新增）
**在编写任何脚本前，必须查看：** `references/script_syntax_critical.md`

这个文档包含了实际脚本编写中最容易出错的语法问题：
- ❌ 使用 `cout` 输出 → ✅ 使用 `print()` 函数
- ❌ `on_initialize` 中使用 `script` 包裹 → ✅ 直接写代码
- ❌ 天线方向图直接定义参数 → ✅ 使用 `constant_pattern` 子块
- ❌ 脉冲宽度用 `microsec` → ✅ 使用科学计数法 `1.0e-6 sec`
- ❌ 使用三元运算符、fmod、类型转换 → ✅ 使用 if-else 和时间差比较
- ❌ WSF_AIR_MOVER 使用 climb_rate → ✅ 只使用支持的参数

### Rule 1: File Extension
```
✅ CORRECT: my_script.txt
❌ WRONG:   my_script.wsf
```
**AFSIM scripts MUST use `.txt` extension, NOT `.wsf`**

### Rule 2: Units Required
```
✅ CORRECT: speed 100 m/sec
❌ WRONG:   speed 100

✅ CORRECT: altitude 5000 ft
❌ WRONG:   altitude 5000

✅ CORRECT: update_interval 1.0 sec
❌ WRONG:   update_interval 1.0
```
**ALL numeric parameters MUST include units**

### Rule 3: End Tags Required
```
✅ CORRECT:
mover WSF_AIR_MOVER
   maximum_speed 500 m/sec
end_mover

❌ WRONG:
mover WSF_AIR_MOVER
   maximum_speed 500 m/sec
# Missing end_mover!
```
**Every block MUST have its corresponding `end_*` tag**

### Rule 4: Coordinate Format
```
✅ CORRECT: position 38:44:52.3n 90:21:36.4w
❌ WRONG:   position 38.44.52.3n 90.21.36.4w
```
**Use colon `:` to separate degrees:minutes:seconds**

### Rule 5: Script API Methods
```
✅ CORRECT: PLATFORM.Name()
✅ CORRECT: PLATFORM.Latitude()
✅ CORRECT: PLATFORM.Altitude()

❌ WRONG: Position()      # Does not exist
❌ WRONG: Geodetic()      # Does not exist
❌ WRONG: Time()          # Use TIME_NOW instead
```
**Only use documented API methods from script_api_reference.md**

**For complete error list:** See `references/common_mistakes.md` and `references/script_syntax_critical.md`

## ⚙️ Configuration

### config.txt - AFSIM Installation Directory

**Location:** `config.txt` in skill root directory

The skill uses a configuration file to locate your AFSIM installation. This makes it portable across different computers.

**Configuration File:**
```
# AFSIM Installation Directory
AFSIM_INSTALL_DIR=D:\Program Files\afsim2.9.0
```

**Derived Paths:**
- **mission.exe**: `{AFSIM_INSTALL_DIR}/bin/mission.exe`
- **Documentation**: `{AFSIM_INSTALL_DIR}/documentation/html/docs`

**To use on a different computer:**
1. Open `config.txt`
2. Update `AFSIM_INSTALL_DIR` to your AFSIM installation path
3. Save the file

All paths (mission.exe, documentation) are automatically derived from this setting.

### Documentation Directory - Ultimate Reference

**Location:** `{AFSIM_INSTALL_DIR}/documentation/html/docs`

The AFSIM documentation directory contains **1602 HTML files** with complete, authoritative information about every AFSIM feature.

**When to use:**
- ✅ Need to confirm very specific details
- ✅ Looking for obscure parameters or options
- ✅ Want to see official examples
- ✅ Need to verify edge cases

**When NOT to use:**
- ❌ For common tasks (use skill references instead)
- ❌ For quick lookups (use SKILL.md navigation)
- ❌ For examples (use examples.md)

**Think of it as:** The ultimate fallback reference when skill documentation doesn't cover a specific detail.

## 🚀 Quick Start Guide

### Step 1: Understand Requirements
Ask the user about:
- **Scenario type**: Air-to-air, air-to-ground, ISR, naval, etc.
- **Platforms**: Aircraft, ships, ground vehicles, satellites
- **Sensors**: Radar, ESM, EO/IR, etc.
- **Weapons**: Missiles, bombs, guns
- **Mission timeline**: Duration, key events
- **Output needs**: Event logs, tracks, engagement results

### Step 2: Generate Script
1. **Start with file structure** (see [File Structure Reference](#-file-structure-reference))
2. **Define platform types** with movers (see [Mover Types](#-mover-types-reference))
3. **Add sensors/weapons** (see [Commands Reference](#-commands-reference))
4. **Create platform instances** with routes
5. **Add processors** for behaviors (see [Script API](#-script-api-reference))
6. **Set simulation end time**

### Step 3: Execute Script
```bash
python scripts/run_mission.py <script_file.txt> [options]
```

Options:
- `-es` - Event-stepped (default)
- `-rt` - Real-time frame-stepped
- `-fs` - Non-realtime frame-stepped
- `-fio` - Flush output
- `-sm` - Suppress messages

### Step 4: Validate and Iterate
- Check mission.exe output for errors
- Verify simulation results
- Adjust script and re-run as needed

## ⚙️ Script Execution

### Configuration

The skill reads AFSIM installation directory from `config.txt`:
```
AFSIM_INSTALL_DIR=D:\Program Files\afsim2.9.0
```

All paths are derived from this:
- **mission.exe**: `{AFSIM_INSTALL_DIR}/bin/mission.exe`
- **Documentation**: `{AFSIM_INSTALL_DIR}/documentation/html/docs`

### Using run_mission.py
```bash
# Basic execution
python scripts/run_mission.py my_script.txt

# With options
python scripts/run_mission.py my_script.txt -es -fio

# Real-time mode
python scripts/run_mission.py my_script.txt -rt
```

The script will:
1. Load configuration from `config.txt`
2. Verify mission.exe exists
3. Display configuration paths
4. Execute the script
5. Capture and display output

### Execution Modes
- **Event-stepped (-es)**: Default, fastest execution
- **Real-time (-rt)**: Runs in real-time with frame stepping
- **Frame-stepped (-fs)**: Non-realtime frame stepping

### Output Files
Scripts generate output in the `output/` directory:
- `.evt` - Event log files
- `.rep` - Binary replay files
- Console output from mission.exe

### Troubleshooting Configuration

**Problem:** mission.exe not found
- **Solution:**
  1. Open `config.txt`
  2. Verify `AFSIM_INSTALL_DIR` points to your AFSIM installation
  3. Check that `{AFSIM_INSTALL_DIR}/bin/mission.exe` exists

**Problem:** Different computer, different path
- **Solution:**
  1. Copy the entire skill directory
  2. Update `AFSIM_INSTALL_DIR` in `config.txt`
  3. Everything else works automatically

---

## 🔍 Troubleshooting

### Syntax Errors

**Problem:** "Unexpected token" or "Parse error"
- **Solution:** Check `references/common_mistakes.md` for common syntax errors
- Verify all blocks have `end_*` tags
- Check coordinate format (use `:` not `.`)
- Ensure all numbers have units

**Problem:** "Unknown command"
- **Solution:** Verify command syntax in `references/commands_reference.md`
- Check spelling and capitalization
- Ensure command is in correct context

### Execution Errors

**Problem:** mission.exe not found
- **Solution:** Verify path is `D:\Program Files\afsim2.9.0\bin\mission.exe`
- Check file permissions
- Ensure AFSIM 2.9.0 is installed

**Problem:** Script file not found
- **Solution:** Use `.txt` extension, not `.wsf`
- Check file path is correct
- Ensure file exists in specified location

### Runtime Errors

**Problem:** Platform not moving
- **Solution:** Check mover parameters in `references/mover_reference.md`
- Verify route has valid waypoints
- Ensure speed is specified with units

**Problem:** Sensor not detecting
- **Solution:** Verify sensor is turned on
- Check sensor range and parameters
- Ensure target is within sensor coverage

**Problem:** Script variables not working
- **Solution:** Declare variables in `script_variables` block
- Check variable types match usage
- Verify semicolons after declarations

## 🎯 Best Practices

1. **Always start with file_structure.md** to understand the standard layout
2. **Check common_mistakes.md** before generating any script
3. **Use examples.md** as templates for common scenarios
4. **Verify mover types** in mover_reference.md before defining platforms
5. **Reference script_api_reference.md** when writing processor scripts
6. **Test incrementally** - start simple, add complexity gradually
7. **Use meaningful names** for platforms, sensors, weapons
8. **Add comments** to explain complex logic
9. **Validate coordinates** - use proper lat/lon format
10. **Check units** - every number needs units
