I failed to get the alignment correct while doing the restrictive movement part, so as of now, just like real chess, you have to manually put the piece somewhere. -Click the piece to pick it up -Hit Space to release
I think I can get the thing with the only-on-the-board movement correctly by the next version. I also realized there's 7 sqaures vertically and 8 squares horizontally, will fix in the next version =================CREDITS================= All done by me, TheMinecrafter555.
