Three.js video tutorial explaining the source code
Youtube: https://youtu.be/JhgBwJn1bQw
In the tutorial, we go through the source code of this game. We cover, how to set up a Three.js scene with box objects, how to add lights, how to set up the camera, how to add animation and event handlers. We also add textures with HTML Canvas and learn how to draw 2D shapes in Three.js then how to turn them into extruded geometries.
Comparing to the tutorial this version has some extra features:
- trucks also pop up on the other track
- the extruded geometry also has a texture
- there are trees around the track
- shadows
- the game reacts to window resizing
Check out my YouTube channel for other game tutorials: https://www.youtube.com/channel/UCxhgW0Q5XLvIoXHAfQXg9oQ
