I have a script to draw rays in the shape of a cone and it works fine when the gameobject is facing directly forwards or backwards but as soon as i change the rotation it starts to change shape and flatten into a 2d cone
using System.Collections;
using System.Collections.Generic;
using System.ComponentModel;
using System.Runtime.CompilerServices;
using UnityEngine;
using UnityEngine.InputSystem;
using UnityEngine.UIElements;
using static UnityEditor.PlayerSettings;
public class Raycasting : MonoBehaviour
{
public float MaxDistance = 100f;
public float Radius = 5f;
public int VertexCount = 10;
public LayerMask Buildings;
private void Update()
{
float deltaTheta = (2f * Mathf.PI) / VertexCount;
float theta = 0f;
Vector3 oldPos = Vector3.zero;
for (int i = VertexCount; i >= 0; i--)
{
Vector3 pos = new Vector3(Radius * Mathf.Cos(theta), Radius * Mathf.Sin(theta), 0f);
Vector3 EndPos = (MaxDistance * transform.forward) + (transform.position + pos);
if (Physics.Raycast(transform.position, EndPos - transform.position, MaxDistance, Buildings))
{
DrawRay(oldPos, pos, true);
}
else
{
DrawRay(oldPos, pos, false);
}
oldPos = transform.position + pos;
theta += deltaTheta;
}
}
private void DrawRay(Vector3 OldPos, Vector3 Pos, bool Hit)
{
Vector3 EndPos = (MaxDistance * gameObject.transform.TransformDirection(gameObject.transform.forward)) + (transform.position + Pos);
if (Hit)
{
Debug.DrawLine(transform.position, EndPos, Color.green);
}
else
{
Debug.DrawLine(transform.position, EndPos, Color.red);
}
}
}
