No Game Engine Game Dev: Word Sleuth 094: Building a solar system on the Chalkboard

Game Engines are for sissies!

There are two more chalk doodads I want to make before I end this phase of development. Today we got a good start on the penultimate one: space. I started out by drawing a chalk sun and getting that to show up on the screen. Then I drew each of the planets and made those render as well.

Once they showed up I gave them elliptical paths around the sun. This is not accurate orbital mechanics at all, but it's not bad for a chalkboard. Uranus has some rings that were running outside the Chalkboard area so I updated the shader to clip. The planets were all starting on the right end of their orbit, so I added a random phase offset to each one. I added sorting so the planets render in the correct order.

Lastly I added a static star field. It needs more stars and there are some other loose ends to improve, but overall the affect is coming along nicely. We'll finish it up tomorrow.
