In this episode I write a Tetris game in JavaScript from scratch.If you like this tutorial you will probably also like my Super Mario Bros tutorial: https://. I just wanted to show that to create a game they’re not always needed. There are many topics like advanced geometries, shaders, lights, skeletal animation, etc., that were not covered here. I hope it was a fun way to learn Three.js.

That’s all folks! Our Tetris is fully functional now. () – in (), where we test for the lost game. () – in (), if there is a ground collision. Tetris.addStaticBlock = function(x,y,z) – in (), if there is no ground collision. The moving block (with merged geometry of a few cubes) is transformed into static, separated cubes that don't move anymore. Let's start with a moment when a moving block touches the floor (or another block).

In our game, cubes will be connected when are dynamic and static when they are not. In 3D, however, we need a quick way to show the z-axis and color is perfect for this. In original 2D Tetris, sometimes the color of a square was the indicator of the origin block. Tracing an origin of a box would require constant splitting and merging geometries and trust me, that would be a crazy mess. In fact, it shouldn't matter - some boxes from a block may be removed and others not. On the other hand, when we try to complete a slice (in 2D, a row) and we succeed, the cubes are removed and the block that was their origin doesn't matter at this point.

Cubes that make blocks are clearly connected and it's intuitive that their representation in code should be as well. The game requires players to rotate and move falling Tetris pieces.

Game Development with JavaScript: Creating Tetris What is Tetris Tetris is a classic arcade game created in 1984 by Alexey Pajitnov. When the block is moving, we transform and rotate it freely.
