A* pathfinder - next target

Question

I'am using Arons A* pathfinding.

I want a character to move from one point to another. I'am just starting with unity and these are my first scripts.

The script doesn't give any errors, but it doesn't work.

What is wrong?

var target : Transform[]; var timer : float = 0.0; var Rate : float = 1.0; private var currentTarget: int;

function FixedUpdate () { timer += Time.deltaTime; if(timer > Rate){ this.GetComponent("Seeker").StartPath(transform.position,target[currentTarget].position); timer = 0; } if(Vector3.Distance(transform.position,target[currentTarget].position)<=0){ currentTarget++; if(currentTarget>=target.Length){ currentttarget = 0; } } }

currentttarget = 0; <---- You have 3 lower case "T"s here

currentTarget = 0; <--- should look like this

The answer:

Rather than check the remaining distance is <=0, maybe try <=.1 The distance returned is probably not negative, and might never really equal 0, so just check if its close.

Tzan thank you for the comment i didn't see that one.

problem however still remains. The script doesn;t go to the next target(/waypoint) it doesn't update

Does it walk to the first waypoint at index [0] if you position the character away from it?

var Rate should be var rate, lower case "r"

I havent used the pathfinding script so if you are using it wrong I cant help.

Rather than check the remaining distance is <=0, maybe try <=.1 The distance returned is probably not negative, and might never really equal 0, so just check if its close.
