2D Collision Detection
I am trying to implement a method that detects a collision between two objects; a moving cannonball (circle) and a stonehenge (created using line renderer). So far this is my code but the DetectCollision method always returns false and is not detecting collision properly:
public class CollisionDetection : MonoBehaviour { public GameObject cannonBall; public PerlinNoise stoneHenge;
bool istrue;
// Update is called once per frame
void Update()
{
print(DetectCollision(stoneHenge.vp, cannonBall.transform.position));
//stonehenge.vp is an Vector3D[] containing vertices of lines that create the stone henge
}
private bool DetectCollision(Vector3[] target, Vector2 obj)
{
for (int i = 0; i < target.Length; i++)
{
//collision detected when the distance between one of the point of stonehenge and the
cannonball <=0.0f
if (Vector2.Distance(target[i], obj) <= 0.0f)
{
istrue = true;
break;
}
else
{
istrue = false;
break;
}
}
return istrue;
}
}
Your distance check will only return true when the target and the object have the exact same transform position. You likely want something like Physics.OverlapBox() or Physics2D.OverlapBox().
