I’ve added dots to show where you can move when you click on a piece. If the position you want to move the piece to the dot is green but if it has an enemy piece the dot is red. Sadly, tkinter (the library I’m using) doesn’t support transparency. Because of this the dot takes up some of piece you want to capture. I can fix this by instead of drawing a circle drawing a translucent image… but tbh i rly cba. I will eventually do it to make it look better and actually add black pieces but i want to focus on getting things to actually work for now. The reason why this took me so long to implement is because as I was making the function to draw the dots I found that it was doing something very similar to my validMove() function but it was MUCH more efficient. In the old function I went through every square on the board and looked if the piece selected could get there. This is very inefficient and would build up quickly when I call the function 1000s of times per second (when I eventually add the bot). In my new function I look at the selected piece and have an array of each of the places it can move relative to its position. I then add the dots to those places if they are able to move there. This ended up with me just completely removing the old function and knowing its a valid move if there is a dot there. Next I am going to add something to see if the king is in check and maybe add some text when it is checkmate.
