# ODE Physics Engine Integration

## ✅ ODE Integration Complete

Full Open Dynamics Engine (ODE) support has been integrated into suicmez for 3D physics simulation, perfect for voxel games!

## Available ODE Functions

### Initialization and Cleanup
- `ode_init()` - Initialize the ODE library
- `ode_close()` - Clean up ODE resources

### World Management
- `ode_world_create()` - Create a new physics world
- `ode_world_destroy(world)` - Destroy a physics world
- `ode_world_set_gravity(world, x, y, z)` - Set world gravity
- `ode_world_step(world, stepsize)` - Advance physics simulation

### Rigid Bodies
- `ode_body_create(world)` - Create a new rigid body
- `ode_body_destroy(body)` - Destroy a rigid body
- `ode_body_set_position(body, x, y, z)` - Set body position
- `ode_body_set_linear_vel(body, x, y, z)` - Set linear velocity

### Mass and Geometry
- `ode_body_set_box_mass(body, density, lx, ly, lz)` - Set box-shaped mass
- `ode_create_box_geom(space, lx, ly, lz)` - Create box collision geometry
- `ode_geom_set_body(geom, body)` - Attach geometry to body
- `ode_geom_destroy(geom)` - Destroy geometry

### Collision Spaces
- `ode_simple_space_create(parent)` - Create collision space
- `ode_space_destroy(space)` - Destroy collision space

## Example Usage

```sui
# Initialize physics
ode_init()

# Create world with gravity
let world = ode_world_create()
let space = ode_simple_space_create(0 as *())  # null parent
ode_world_set_gravity(world, 0.0, -9.81, 0.0)

# Create a falling voxel/box
let body = ode_body_create(world)
ode_body_set_box_mass(body, 1.0, 1.0, 1.0, 1.0)  # 1x1x1 meter box
ode_body_set_position(body, 0.0, 5.0, 0.0)        # Start 5 units up

let geom = ode_create_box_geom(space, 1.0, 1.0, 1.0)
ode_geom_set_body(geom, body)

# Simulate physics
let mut i = 0
while i < 100 do
    ode_world_step(world, 0.016)  # 60 FPS
    i = i + 1
end

# Cleanup
ode_geom_destroy(geom)
ode_body_destroy(body)
ode_space_destroy(space)
ode_world_destroy(world)
ode_close()
```

## Compilation

Use the updated compile scripts which now include ODE:

```bash
./compile.sh tests/your_ode_program.sui
./compile_and_run.sh tests/your_ode_program.sui
```

## ODE Version

Currently using: **ODE 0.16.6**

- Real-time rigid body dynamics
- Collision detection
- Joint constraints
- Stable simulation for games

All ODE features are now available through suicmez for building physics-based voxel games!</content>
