Welcome to the course where we build a self-driving car simulation in a virtual world. In this video Ill teach you how to build a graph editor from scratch, using basic HTML, CSS and JavaScript. The graph will act as a basis and the world will be generated according to it.
In this digital age, a good user interface should streamline interactions, minimizing the need for excessive clicks and keyboard inputs. Ill teach you how to do this when making a graph editor and how to think like this in general.
Throughout this series, Ill guide you step by step, showcasing how to build a graph editor with a primary focus on mouse interaction. The mouse is a versatile tool, and in this course, we use it to add, drag, remove points effortlessly. 🖱️
Well start from the basics, gradually implementing new features and refining existing ones, all with the aim of achieving a final logic thats not only functional but also intuitive. By the end, youll not only have a graph editor to be proud of but also the skills to customize it to your hearts content.
Have Fun! :-)

Welcome to the course where we build a self-driving car simulation in a virtual world.
In this video, we learn a way to make our items 3D. While you could certainly add some sprites to your existing 2D interface, creating a 3D look is a whole different experience.
Ive previously demonstrated how to use images for adding cars, and even offered tips for recoloring sprites in previous tutorials. But what if youre aiming for a genuine 3D appearance? You could completely refactor your application to utilize a 3D rendering engine. Like:
⭐ Bretto ported the code from Phase 1 to ThreeJS:
https://github.com/Bretto/evolution
⭐ @davidmurphy563 ported the code from Phase 1 to Godot:
https://youtu.be/FJFrSCEWqLU?si=toU4O43h2oaJmKUy
I want to teach you a way to get the 3D look without using a 3D engine because I find this effect visually appealing, and its surprisingly straightforward to implement.
Beyond the visual aspect, you may also find the underlying mathematics intriguing. While 3D renderers primarily employ triangles or voxels, our focus wont involve these elements. Nonetheless, this exploration touches upon fundamental principles of 3D rendering, providing insights into how these complex systems function.
Have Fun! :-)
