        showCheckpointScreen("You reached the final checkpoint!");
        movePlayer("ArrowRight", 0, false);
      } else if (player.position.x >= checkpoint.position.x <= checkpoint.position.x + 40) {

Hello,
Your error lies in the if condition, You need to know that no programming language is capable of evaluating such expression player.position.x >= checkpoint.position.x <= checkpoint.position.x + 40
Let’s say you want to make sure a variable called a is great than or equal than a variable called b & at the same time less than or equal to a variable called c, well in JS, in order to do this, you need to use the and logical operator &&, this operator will evaluate to true if the expressions on the left & on the right are true

if(a >= b && a <=c)

Thanks . The explanation was very helpful. :pray: once again
