HTML5 level select screen featuring swipe control, stars, progress saved on local storage, smooth scrolling, pagination and more. Powered by Phaser 3
Two years ago, I built a HTML5 level select screen controlled by swipe with level selection, stars, progress saved on local storage and some other nice features everybody expects from a modern game.
I ported it to Phaser 3 mainly because I was really needing something like that for a project, so let’s jump straight to the point and see what I did:
Swipe pages or using the buttons on the bottom to jump straight to a page, select levels and play. Play levels, fail them or complete them with 1, 2 or three stars, unlock levels and do everything you would expect from a professional level select screen.
The core of the idea is the background tile sprite the player drags. A series of callbacks and tweens do the rest in this uncommented source code – but you can find the commented Phaser 2 version in the original post.
This is not a beginner script as there are more than 200 lines of code, but a more optimized and commented version will come in a few days. I am using it in my latest game so I am polishing it a bit.
If you have questions, feel free to leave a comment or drop me a mail, the best ideas will be developed in next step, meanwhile download the source code.
