Hello, I was following the Laser Defender guide part 11 (Pathfinding). And encountered an issue with enemy not following the waypoints. I did everything exactly as in video. And My first route was working fine, but when I added new path and attached it to new enemy prefab, the enemy just stay on the first waypoint. When I tried new path on my first enemy, it stopped moving too. It started all over againg rewrote the scripts. And the enemy did not move at all this time. I serialized all i could to check if something was missing. But everyithing was ok.
I noticed that the waypoing index was not increasing in Inspector. When i manually incremented it, the ship started to move to second waypoint. When i dragged the ship right after play button was pressed it moved to the very first waypoint and stopped there.
So i figured out that something didnt let the index to increment. The compiler did not show any error.
I accidently replaced Vector2 with Vector3 in the Pathfinder script in the line:
float delta = waveConfig.GetMoveSpeed() * Time.deltaTime;
transform.position = Vector2.MoveTowards(transform.position, targetPosition, delta);
to:
float delta = waveConfig.GetMoveSpeed() * Time.deltaTime;
transform.position = Vector3.MoveTowards(transform.position, targetPosition, delta);
and then everyting started to work again.
In video it is mentioned that one has to use Vector3 insted of Vector2 in the line
Vector3 targetPosition = waypoints[waypointIndex].position;
to make this condition not give error:
if(transform.position == targetPosition)
{
waypointIndex++;
}
But even if it doesnt show any error, there should be all vector 3’s to make script work
