Rotation
Explore how to implement piece rotation in Tetris using matrix transposition and array reversal in JavaScript. Understand the role of immutability, apply keyboard event handling for rotation controls, and enhance gameplay by making pieces rotate smoothly.
We'll cover the following...
Now we can move around, but to make it more fun, let’s make the piece rotate. This is what the different stages of rotation should look like:
As with most components of this game, there are a few ways we could go about solving this challenge. We could, for example, have all the different variations of matrices defined and loop through them. However, this would require a lot of boilerplate code, so let’s not take that route this time.
Linear algebra
Instead, there is a mathematical formula in the linear algebra branch of mathematics that we can use. The ...
