Matrix Class (NxN). Is there any?

AnthropomorphicBeing

I want to represent Tetris pieces with a matrix so I can rotate it easily. I can only find a Matrix3 (3x4) class, and a Matrix32 (3x2) class. Is there a matrix class to use with other dimension?

You don't need a matrix. You can use transforms to rotate objects. Read this page to see more: https://docs.godotengine.org/en/stable/tutorials/3d/using_transforms.html

Thanks, but as I understand it, I do need a matrix to rotate the data representing my pieces. this is an example of a piece:

var L := [[1, 0], [1, 0], [1, 1]]

For tetris, I did this same thing one time. What I did was define all four positions, and switch them. Hard coded.

I see, so you're not using transformation matrices, you basically have a multi-dimension array to store the pieces. That is something entirely different than what I thought.

In that case, just make your own rotate functions. It should be fairly simple, just indexing in a different order. I found this code which looks like it should work, but I didn't test it. In any case, it's just a matter of looping through the array and creating a new array with a different order of elements.
