🚨 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)
2. Define platform types with movers (see Mover Types)
3. Add sensors/weapons (see Commands Reference)
4. Create platform instances with routes
5. Add processors for behaviors (see Script API)
6. Set simulation end time

Step 3: Execute Script

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

# 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
