Built-in Bundle

The arepy.bundle package contains reusable components and systems intended to cover common game patterns.

Available components

The current public bundle exports:

• RigidBody2D
• Sprite
• Transform
• Camera2D
• Camera3D
• Model3D
• Material3D
• Light3D
• Transform3D
• Mesh3D

Frequently used 2D components

Transform

Transform stores:

• position: Vec2
• scale: Vec2
• origin: Vec2
• rotation: float

Default vectors are created per instance, so different entities do not accidentally share mutable defaults.

RigidBody2D

RigidBody2D stores:

• velocity: Vec2
• acceleration
• deceleration
• max_velocity

Sprite

Sprite stores:

• asset_id
• src_rect
• z_index
• flipped

Built-in systems

The current bundle systems package exposes two reusable systems:

• movement_system
• render_system

Both use query-driven iteration over components rather than entity lookups inside the hot loop.
