Hi Narkka, the feature you are looking for is called vector-targetting. To implement this on all projectile weapons, you’ll just need to replace the GetSpawnAngle() function shared in Part 15’s ProjectileWeapon.cs script with the following:
// Gets which direction the projectile should face when spawning.
protected virtual float GetSpawnAngle()
{
Vector2 dir = (Vector2)Input.mousePosition - transform.position;
return Mathf.Atan2(movement.lastMovedVector.y, movement.lastMovedVector.x) * Mathf.Rad2Deg;
return Mathf.Atan2(dir.y, dir.x) * Mathf.Rad2Deg;
}
If you want to implement this on only a specific weapon / weapons, you will need to extend ProjectileWeapon and override GetSpawnAngle(). Something like this:
public class VectorProjectileWeapon : ProjectileWeapon
{
protected override float GetSpawnAngle()
{
Vector2 dir = (Vector2)Input.mousePosition - transform.position;
return Mathf.Atan2(dir.y, dir.x) * Mathf.Rad2Deg;
}
}
I hope this makes sense! Basically, we just need to compute a direction vector based on the mouse position of the user. If you want to learn more about the mathematics behind this, you can check out this article: https://blog.terresquall.com/2020/01/vector-math-for-polar-movement-in-2d-games-unity/
