Physics Engine (ODE) + +ODE (Open Dynamics Engine) provides rigid body dynamics, collision detection, and constraint solving. The key components are: + +- **World**: The container for all physical objects and gravity +- **Bodies**: Dynamic rigid bodies with mass, velocity, and position +- **Geometries**: Collision shapes (boxes, planes, spheres, etc.) +- **Space**: Collision detection space that organizes geometries +- **Contacts**: Joint constraints created when objects collide + +### 2. Graphics Engine (Raylib) + +Raylib provides 2D and 3D graphics, input handling, and audio support. + +### 3. Integration Pattern + +The key to proper physics is the **collision detection loop**: + +```sui +# Initialize +ode_init() +ode_space_collide(world, space, contactgroup) +ode_world_step(world, timestep) +ode_joint_group_empty(contactgroup) +``` + +**Important**: You must call collision detection **before** world step, and clear the contact group **after** the step. + +## Step-by-Step Tutorial + +### Step 1: Initialize the World + +```sui +fn main() -> int do + # Initialize graphics + init_window(800, 600, "My Game") + set_target_fps(60) + + # Initialize physics + ode_init() + let world = ode_world_create() + let space = ode_simple_space_create(0 as *()) + let contactgroup = ode_joint_group_create(0) + + # Set gravity (9.81 m/sĀ² downward) + ode_world_set_gravity(world, 0.0, -9.81, 0.0) + + # ... rest of code +end +``` + +### Step 2: Create Physics Objects + +Each dynamic object needs: +1.
