In this chapter, we learned the final pieces to build complete apps and games on the web; coupled with what we learned earlier, our journey is nearly complete; this is really just the first step toward bringing reality to the web. The topics we covered included how to move in a VR world, including basic teleport mechanics. We discussed Gaze buttons and using ray casting to implement them. We discussed the important mechanics of props, state, and events. To implement these flows, we went over the important React philosophy of pushing state up and handling events down stream. We also discussed using pseudo random number generators to make sure that our props and state didn't change chaotically. All together, we now know how to create, move around in, and make worlds react to us.

In the next chapter, we'll discuss where to go from here, how to upgrade React VR, and how to publish your virtual worlds on the internet.
