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/SpaceshooterFlight-lesson-10/scene.json:

bjs download scene SpaceshooterFlight-lesson-10 --all

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

Everything behind your rocks is clearColor — one near-black RGBA in the scene header, painted over the whole frame every tick. It has served, because the rocks and the tracers have been carrying the eye. Look up and the illusion ends: nothing above you, nothing below, no direction that looks any different from any other.

Plus the plugin, registered at bootstrap next to last lesson's:

const adapter = new BabylonAdapter();
registerShipDamageFXExtension(adapter);
registerNebulaSkyExtension(adapter);
