I'm making a 2 player maze game in Scratch. Basically, there's a complicated maze and whoever makes it to the end first wins. However, I want to make it so that every time a player were to retrace his/her steps (i.e. revisit the same coordinates he/she has already passed), points would be deducted from that player's score. It's like a penalty for the player going the wrong way or trying every possible path, since that would eventually lead them easily to the finish. What script would I use in order to do this? How do I attempt to go about this? I am using arrow keys, by the way. I appreciate the help! Thank you!

You could use a variable to store which direction they are going and whenever they go in the opposite direction then deduct a point.

e.g.
if key up arrow pressed then
if stored direction = down then
change score by -1
set stored direction to up

Other possibility is to leave little signs (as in the fairy tale, little pieces of bread) so, if you trace back, when touching signs points will be deducted.
Signs can be seen or not, setting ghost effect to 100.

You can use lists to store the x-y values of the path, then have it so that if the sprite is within ~half the sprite's diameter of one of the x-y values stored in the lists, it deducts a point.

So im making a maze game also, for some reason my sprite im using to give the player points doesnt switch costumes when it gets touched, it also adds alot more points then just one.
