"This project was born out of a desire to learn Blazor, and to attempt to stick to C# and CSS in the process. It is an experimental clone of Tetris built as a Blazor component. The game uses CSS Grid to position SVG blocks on the play area, so moving a piece is just a matter of changing it's CSS grid position, which is handled in C#. There is a main Game Task that controls the spawning of new pieces, keeping track of scoring and other top level controls, while each Tetromino has its own Task that controls it's movement and rotation. There were very few technical challenges along the way, but one problem faced with running a game in the browser without JS was getting focus for key presses. Simplicity saved the day, by including a Start button in the game area, focus was gained by the user clicking the button. This is an experiment, not a complete project, but I do plan to extend the project as more training for myself. I'm currently working on using Azure functions, CosmoDB and SignalR to implement a high score table, as a way of demonstrating those technologies in Blazor."
