Rigbody 2D Velocity Mystery
I am fairly new to rigidbody velocity and how to get it to work properly. Currently, with the code below, my player marker will move across the screen towards where I last clicked on the screen. Once it arrives at where I last clicked it will stop. All of this works just as I had hoped. My only issue is that when I click somewhere relatively far (player marker on left side of screen and I click right side of screen) my marker moves at a desirable speed, but if I click relatively close to where my marker currently sits then I notice the velocity seems extremely low. Can anyone help me fix my code to where my marker will always move at a set velocity to its destination, no matter how far or near? Thanks!
public class PlayerMarker : MonoBehaviour
{
Rigidbody2D rig;
public float moveSpeed;
private Vector3 targetDestination;
void Start()
{
rig = GetComponent<Rigidbody2D>();
}
void Update()
{
if(Input.GetKeyDown(KeyCode.Mouse0))
{
targetDestination = Camera.main.ScreenToWorldPoint(Input.mousePosition);
Move(targetDestination);
}
float distanceFromDestination = Vector2.Distance(transform.position, targetDestination);
if(distanceFromDestination <= .01)
{
rig.velocity = Vector2.zero;
}
}
void Move(Vector3 destination)
{
Vector2 dir = (destination - transform.position).normalized;
rig.velocity = dir * moveSpeed;
}
}
I use a similar logic for enemy markers that will chase me and their movement speed across the screen does not change based on distance from their target (my player marker). The only thing these two scrips do not have in common is the use of ScreenToWorldPoint. I'm not sure if my problem lies somewhere in regards to how I use ScreenToWorldPoint to calculate my target destination for my player marker.
I have discovered the issue. At the top of my code I have set targetDestination to be a Vector3 instead of a Vector2. I believe my player marker was also moving along the Z axis, which was affecting the speed based on how close I was to my player marker when I last clicked (set new destination).
