Simple C# script to follow breadcrumb trail

Hi all,
I come to this Forum as an artist teaching myself basic coding to create some projects. I decided not to post the script I'm using as it is a digital patchwork mess and would only take up more time pointing out where it was going wrong.
Basically, I have a player character with a script attached which drops basic breadcrumbs (which is the underlying element of the puzzle game) and I need to have the second character follow these breadcrumbs. Nothing else.

I've tried using GetComponent in a movement script attached to the second character to use the player character's breadcrumb script, but I'm just not getting it, and it's been over a week now, and I need help please.

Anything would be worthwhile.
Thank in advance . . .

 

I would have a script on the follower guy that stores an array of the transforms of the breadcrumbs that the first guy has dropped then a navmesh or some script that always seeks the breadcrumb on the top of the arraylist. when they finally get there, use a tigger or maybe a vector3distance test to call a method that says "found it" that removes the top item on the breadcrumblist and reorders the array

 

Thank you for that frankrs. Would the fact that I would be using this breadcrumb data for up to 7 further following characters pose an issue?

 

well, if you want to destroy the breadcrumb when any one gets to it you would need to send the "fount it" call to all seven of them or else you will get a null reference exception when the rest are looking for a missing breadcrumb

 

I see, so there is not a solution for having the breadcrumb trail remaining intact for others to follow? Well, that's plenty to get my teeth into for now, thanks again and have a good weekend.

 

you can surely keep your breadcrumb trail, you dont have to destroy them
