AI script works, when we add a blocked function it stops working HELP
Hey, me and my friend are making a 2D platformer. My friend works on the AI and I work on the player mechanics. My friend ran into this problem that we can't solve, we are beginners to unity so our script may be sloppy. Our problem is that we made an AI that shoots the player when detected, this works but he would shoot at the player even when he was behind objects. We tried to solve this by making a raycast that tries to detect if something is in the way of the enemy and the player, However, our function that we added completely breaks the enemy's movement and it doesn't even work. I'll post the full script and then the area that breaks the script. Even when we remove the faulty function, the movement of the enemy is still broken. Please help!

Here is the part that breaks the script:
RaycastHit2D rey = Physics2D.Raycast (transform.position, target.position - transform.position, vision, hl);
if (rey) {
if (rey.collider.gameObject.name == "Ground") {
blocked = true;
} else {
blocked = false;
}
} else {
blocked = false;
}
