Catching up?

Dropping in at this lesson? One command reinstalls the library components the build uses so far and writes the scene as it stood at the end of the previous lesson to public/scenes/WingmanFlight2/scene.json:

bjs download scene WingmanFlight2 --all

Copy that scene.json over your src/scenes/wingman.json and you are caught up to the start of this lesson.

Last lesson ended with a working lock but a dead key. You point your nose at a fighter. TargetingSystem fills lockedTargetId, and the crosshair sticks. But tapping Space does nothing. The launcher knows what to shoot. It just has no missile to send and nothing to steer it home. This lesson builds that missile so the lock can finally kill.
