     5→# Anchor Engine Overview
     6→
     7→Anchor is a 2D game engine for solo indie developers. It combines a C core with YueScript (a language that compiles to Lua) for game logic. The engine handles rendering, physics, audio, and input while the framework provides high-level abstractions for building games quickly.
     8→
     9→---
    10→
    11→## Core Philosophy
    12→
    13→**Locality** — Everything about a game object lives in one place. No scattered configuration files, no registering components in separate systems. A class definition contains its properties, behaviors, children, and cleanup logic together.
    14→
    15→**No bureaucracy** — No imports, no dependency injection, no boilerplate. Resources are registered once and accessed globally. Things work without setup.
    16→
    17→**YueScript** — A clean syntax that compiles to Lua. Classes, `@` for self-reference, significant whitespace, operator overloading. Pleasant to read and write.

Based on the search results, I found relevant information about Box2D 3.1 shape enabling/disabling functionality:

The search results include references to the Box2D API header file. In the context of Box2D 3.1, the functions related to enabling/disabling shapes appear to be part of the shape API. There is a function `b2Shape_SetSurfaceMaterial` for setting shape properties, and the documentation indicates various shape manipulation functions are available.

However, the specific functions `b2Shape_SetEnabled` and `b2Shape_Enable` that you mentioned in your query don't appear explicitly in these search results. The search results focus more on general shape properties, contact events, and sensor functionality in Box2D 3.1.

To get more precise documentation on those specific shape enabling/disabling functions, you may want to:

1. Check the official Box2D 3.1 API documentation at box2d.org
2. Review the Box2D header files on the GitHub repository (erincatto/box2d)
3. Look for the complete shape API reference in the Box2D 3.1 release notes

Would you like me to search for more specific information about these functions?

# Shape Management Functions in Box2D 3.1.0

Based on the documentation, here are the key functions for shape lifecycle management:

## Destroying Shapes

**`b2DestroyShape()`** - The primary function for removing shapes:
> "Destroy a shape. You may defer the body mass update which can improve performance if several shapes on a body are destroyed at once."

This function accepts a shape identifier and a boolean flag to control whether the parent body's mass properties update immediately.

## Enabling/Disabling Features

Box2D provides several functions to toggle shape behavior at runtime:

- **`b2Shape_EnableSensorEvents()`** - Activates sensor overlap detection
- **`b2Shape_EnableContactEvents()`** - Turns on collision event notifications (kinematic/dynamic bodies only)
- **`b2Shape_EnablePreSolveEvents()`** - Enables pre-solve callbacks for dynamic bodies
- **`b2Shape_EnableHitEvents()`** - Activates impact event detection

Each corresponding function allows disabling these features by passing `false` as the flag parameter.

## Important Note

The documentation explicitly states regarding sensor status: "It is not possible to change a shape from sensor to solid dynamically because this breaks the contract for sensor events."

# Box2D Shape Functions Analysis

Based on the content provided, here are the relevant findings:

## Shape Destruction
```c
B2_API void b2DestroyShape( b2ShapeId shapeId, bool updateBodyMass );
```

This function destroys a shape with an optional parameter to defer body mass updates.

## Enable/Disable Functions

**There is no `b2Shape_Enable` or `b2Shape_Disable` function** in this header file. 

However, there are related functions for controlling shape behavior:

- **`b2Shape_EnableSensorEvents`** - "Enable sensor events for this shape"
- **`b2Shape_EnableContactEvents`** - "Enable contact events for this shape"
- **`b2Shape_EnablePreSolveEvents`** - "Enable pre-solve contact events for this shape"
- **`b2Shape_EnableHitEvents`** - "Enable contact hit events for this shape"

These control event generation rather than shape simulation itself. To disable a shape from simulation, you would need to destroy it with `b2DestroyShape` or use body-level controls like `b2Body_Disable` or `b2Body_Enable` on the parent body.

Calculate the weapon tip position\n   - Cast a ray in the attack direction\n   - Return `true` if a raycast hits an enemy ball\n\n2. **Ray Lengths**: \n   - Gun: 500 pixels\n   - Sword: 120 pixels (shortest range)\n   - Bow: 500 pixels (same as gun)\n\n3. **Boomerang Difference**: The boomerang weapon doesn't use alignment checking\u2014it auto-attacks whenever ready without caring if the enemy is in line of sight. This makes sense mechanically since the boomerang curves back automatically.\n\n4. **Boomerang Special Effects**:\n   - Destroys weapon shapes to make the ball defenseless during the throw\n   - Randomly decides up/down side for the throw\n   - Uses turn_rate and angle_offset to create the curved return path\n   - Applies a spring pull effect for visual feedback"

User has answered your questions: "Which parry hit effect specifically? I see a few possibilities: (1) weapon-weapon parry at line 763 uses Box2D contact point directly, (2) the boomerang projectile hitting a ball uses midpoint at lines 961-962, or (3) the melee weapon-ball hit effect at lines 1055-1056 is skipped for boomerang.

User has answered your questions: "The Box2D contact point should already be in world space including shape offsets. I notice the boomerang has `weapon_perpendicular_offset = 6` (visual) but `weapon_hitbox_offset_y = 8` (physics hitbox) — these being different could cause visual mismatch. Is the issue that the hit effect appears offset from where the weapons visually collide, or is there something else going on?"="Let's leave it for now." user notes: Let's leave it for now..
