Taylor Nodell shares an excellent tutorial on creating an isometric scene in Phaser!
Creating an isometric scene can be complicated, but in this tutorial by Taylor Nodell, you get to learn how you can create a simple isometric scene by using the phaser3-plugin-isometric. In the tutorial, Taylor starts by giving a brief introduction to isometric art, provides some information on the isometric plugin, and then walks you through setting up the Phaser 3 Scene.
From the article: "I’ve been working on a casual flower genetics game, in the Phaser 3 engine. I’d always imagined it having a pseudo 3D effect, and after building it to this point, I wanted to try to finally get the visuals in a workable place.
And with that we’ve got a little isometric scene started. Certainly a couple places to refactor and smooth out, but it’s looking much better that what I had previously."
