Well, actually it cannot work the way that you depict in the scene. Here's why: In chess, en passant ( French: "in passing") describes the capture by a pawn of an enemy pawn on the same rank and an adjacent file that has just made an initial two-square advance. The capturing pawn moves to the square that the enemy pawn passed over, as if the enemy pawn had advanced only one square. At that point the captured pawn is removed from play. That's why it can happen only once, not infinitely as your scene depicts.

Sorry...

Oh, one more thing... The chessboard shown in your scene must be rotated 90 degrees in order to play a correct game of chess. (The lower-right hand square must be white, not the dark color as you have it). That's a common mistake that many inexperienced chess players make, especially here on Algobox).

Sorry again...

This scene has made my day after I lost two tournament chess games by touch-move (and opponent insisting to continue play after threefold repetition and accepted draw )

Xray
ik that its impossible for there to be infinite en passants, i mainly just made this because haha funny pawn edit: also so i didnt just randomly post nothing for a month, but the doge nuggets scene was making that not happen anyways so oh well
also thanks for telling me about the wrong board, it was supposed to make it look like an infinite board but i couldnt really put infinite squares in the scene

a_bored_coder -- Hey no problem. Algodoo is here for fun, and if we can't have fun (while occasionally getting educated) then it's not worth doing. Some of my own scenes are rather silly, and I've posted them just to get some laughs. I love this stuff!

a_bored_coder -- I now see what the problem is.... You used a checkerboard pattern that has 64 by 64 squares. That's a total of 4096 squares!
A chessboard has 8 by 8 squres (a total of 64). If you wanted to be correct, you can mask off the extra squares or simply delete them. Then you will have a proper chess board.

This is just a suggestion. It's totally up to you what you do with your own scenes.

Xray
its actually 512 squares (the dark squares arent actually geometries but holes in the pattern, and its only a 32x32)
i also tried to make it look more like its actually infinite

Oh, Okay. Anyway, it's a cool animation that you did!

Queen be like:
