CollisionChecks

These implementations are based on the examples provided by Jeffery Thompson

This static class provides simple math solutions for determining overlap of specified shapes. These will all return a bool value

• Rectangle
  • Rect2Rect()
• Line
  • Line2Line()
  • Line2Circle()
  • Line2Point()
• Circle
  • Point2Circle()
• Point

PhysicsLauncher

For 3D support, use the PhysicsLauncher3D

This struct is a helper that provides a random velocity based on the parameters set by you. The intention is that this is called elsewhere to get the information

• SpawnLocation: This can be retrieved to use as the spawn location, but is also used to display the gizmos
• spawnAngle: The number of degrees in either direction that the prefab can aim in

  • Quaternion.Euler(0f, 0f, Random.Range(-spawnAngle, spawnAngle)) * spawnDirection.normalized;

Gizmos

There is the option to display the Gizmos for this, however, it must be called outside

private void OnDrawGizmos()
{
    launcher.DrawGizmos();
}

This example will launch a new rigidbody based prefab once every second.

[SerializeField]
private Rigidbody prefab;
[SerializeField] 
private PhysicsLauncher launcher;

private float _time;

private void Update()
{
    if (_time < 1f)
    {
        _time += Time.deltaTime;
        return;
    }
    _time = 0f;
    
    var newInstance = Instantiate(prefab, transform.position, Quaternion.identity);
    newInstance.velocity = launcher.GetLaunchVelocity();
}
