Question by ivanchenko23 · Aug 01, 2018 at 07:09 PM · scripting problemgameobject

bug with Raycast?

I want to let a Raycast between two characters, but it's going in the wrong direction (ray #2) alt text

And DrawLine with the same settings as the Raycast is in the right direction (ray #1)

 //#1
         Debug.DrawLine(this.transform.Find("Target").transform.position, i.transform.Find("Target").transform.position, Color.red);
         //#2
         if (Physics.Raycast(this.transform.Find("Target").transform.position , i.transform.Find("Target").transform.position, out hit , dist))
         {
                 Debug.DrawLine(this.transform.Find("Target").transform.position, hit.point, Color.red);
                 
                 if (hit.transform.tag == tagE)
                 {
                     
                     hit.transform.GetComponent<Helth>().CurrentHP -= 1;
                     
                 }
         }


What's wrong?

For debugging raycast you might also look at the [Debug.DrawRay] : https://docs.unity3d.com/ScriptReference/Debug.DrawRay.html

Raycast and Drawline have two different casting systems: raycast works with a vector for the ray direction (from -> into direction), drawline works with start and end point (from -> to). You will need to calculate the direction vector by position difference (Character2.transform.position - Character1.transform.position).
