In this episode, we connect the camera to the character the correct ECS way.

We introduce an Aim component, build a clean camera-to-player data pipeline, and make strafe mode face the camera direction — without tightly coupling systems.

No hacks. No cross-system reach-ins.
Everything flows through components.

You’ll learn:

• How to design an Aim component
• How to create a Camera Basis system
• How to separate movement direction from facing direction
• How to build a proper ECS data pipeline
• How to implement camera-relative movement
• How to support Face-Move and Strafe modes cleanly

This is how real engine architecture works.

By the end of this episode:
✔ Camera writes yaw data
✔ Player reads movement basis
✔ Strafe mode faces camera direction
✔ Face-Move mode faces movement direction
✔ Systems remain fully decoupled

This is scalable ECS architecture — the foundation for aiming systems, lock-on mechanics, and combat later.

We are no longer building a demo.
We’re building a real 3D engine from scratch.
