Simple path finding with trail behind player

I have always struggled with path finding, so I am trying to do a workaround which on paper seems simple: create breadcrumbs behind the player for the enemy to follow.

I've got the breadcrumbs working, but I'm struggling with rest of the enemy logic. Attaching the MFA if anyone would like to take a look.

i don't understand exactly what you want

Sorry, I'll try to describe it better.

I am trying to have the red figure to path find to the green figure. Proper path finding is difficult to do, so I want to simplify it.

Consider the image below. The green is the player, while the red is the enemy. Imagine the player is detected by the enemy, then the player then moves behind the wall. Now the enemy will try to follow, but it will simply crash into the wall.

To do the simplified path finding, I add "breadcrumbs" behind the player. These are supposed to be invisible detectors. Consider the second image below.
1. The enemy cast a ray towards the player, but it hits an obstacle so it stops moving to the player
2. The enemy then cast a ray towards the breadcrumbs. It needs to find the breadcrumb which is in view and has the highest ID (as this is closest the the player). It then moves to that breadcrumb until a higher ID is in view or...
3. ... the player is in view of the ray caster, the enemy then simply moves to the player

If neither the player or any breadcrumbs are in direct view, the enemy stops following.

Here is a simple working version of follow the player.

I think follow the path would be easy if I could do nested loops within the for each object

Nice, that seems like a really useful extension!

I did make another solution which probably isn't as good, but works fine. Attaching the file in case it's useful for anyone else.

Here the enemy will walk towards the player when detected. When the player is lost, the enemy will go to the last known location.
