hello, I am working on re-designing a wall running script. the script is a Frankenstein’s monster of both unity’s Character Controller script, and my own scripting understanding.
my biggest dilemma is that while I have the player running and all that, I don’t know how to separate the vector described below into left and rights. I’m doing this because that way I can use the vector to determine which side the wall is compared to the player.
directions = new Vector3{
Vector3.right,
Vector3.right + Vector3.forward,
Vector3.forward,
Vector3.left + Vector3.forward,
Vector3.left
};
Tl;Dr: I need help determining whether the wall is on the left or right side of the player.
I know how to solve several other issues; however, I just want to get this bigger issue out of the way first.
[180329-wallbuildup.txt*_|180329] the script works alright if you’re looking for a character controller-based movement script for anyone wanting to know. it sticks the player against a wall automatically, letting them slide against it.
public class WallBuildup : MonoBehaviour
{
public float normalizedAngleThreshold = 0.1f;
public CharacterController controller;
//the player character
public Transform Player;
public Transform cameraRot;
//attaching to wall

private Vector3 lastWallNormal;
//wallrun stats
public float wallSpeedMultiplier = 5f;
public bool wallOnLeft;
//camera stuff
public float maxAngleRoll = 20;
[Range(0.0f, 1.0f)]
public float cameraTransitionDuration = 1;
//jump offs

Vector3.left
};
}
//this function determines wether or not a runnable wall is within range.

{
float d = Vector3.Dot(hit.normal, Vector3.up);
if (d >= -normalizedAngleThreshold && d <= normalizedAngleThreshold)
{
