How to rotate a block in python without getting through in grid and the other blocks in tetris

Question

The block doesn't rotating and also the block keeps on getting through in other blocks

Answer 1

You can implement collision detection algorithms Mentor sir Ausgrindtube already mentioned.

This Algorithm can check for overlaps with existing blocks after each rotation operation. If a collision is detected, prevent the rotation from occurring or adjust the block's position accordingly to avoid trespassing onto other blocks.

Answer 2

You would have to program them to "collide" or know of the space of the other blocks etc.
