How to calculate Debug.DrawRay length to match raycast
Hi everyone, I've come across a bit of a problem. I am trying to work with some rays however when I tried to add a visual element to it I noticed something was wrong. I realize that you assign a length to a raycast from it's origin point but in drawray you have to multiply the direction to get a longer ray. However if you have a number that isn't 1 in your vector3 coordinates it will not calculate correctly. So heres is my code that seems to be pretty close. Notice how the raycast is 2 units long but the DrawRay is getting multiplied by 0.7. What I want to know is how to calculate this number correctly. Surely there's a math solution to this that you guys know.
if(jlpRayDuration >= Time.time)
{
var jlpRay = Physics.Raycast(botAttack.transform.position, transform.TransformDirection(Vector3(1.5, 2, 0)), 2);
Debug.DrawRay(botAttack.transform.position, transform.TransformDirection(Vector3(1.5, 2, 0)) * 0.7, Color.green);
}
P.S. I know the reason it's messing up is because if I had multiplied by 2 in the DrawRay it woulda done Vector3(1.5 2, 2 2, 0 * 2) giving me (3, 4, 0). Pretty sure that's what's messing it up although after typing it here it seems like it should still make sense.
Normalized the direction vector and multiply by the distance you use in the Raycast method.
Vector3 direction = transform.TransformDirection(Vector3(1.5, 2, 0)).normalized;
float distance = 2f;
var jlpRay = Physics.Raycast(botAttack.transform.position,direction, distance);
Debug.DrawRay(botAttack.transform.position, direction * distance, Color.green);
