i want each projectile in my game to contain a bool saying if its the player's or not

public interface projectile
{
    public bool isPlayers { get; set; }
}

public class Bullet : MonoBehaviour, projectile
{
    public bool isPlayers { get { return (_isPlayers); } set { _isPlayers = value; } }
    private bool _isPlayers;
}

when any weapon fires i check if it was by the player or not and set it accordingly

public class Cannon : MonoBehaviour, Iaweapon
{ 
    ...
    public void Attack()
    {
        ...
            if(transform.parent.tag == "Player")
            {
                prefab.GetComponent<projectile>().isPlayers = true;
            }
        ...
    }
}

but when debugging the bool is not set to true

CodePudding user response：

Your class does not implement your interface.

In order to do it you will have to add it as you did for Iaweapon interface.

 public class Cannon : MonoBehaviour, Iaweapon,  projectile
{ 
    ...
    public void Attack()
    {

Also in order for you to be able to recognise easier your different types such as interfaces I recommend you putting an "I" before all of you your interface names. It will make your life easier.

Given the varialbe names, I'm going to assume that you're checking a 'prefab' instead of an instantiated object. With that in mind, your code should look something more like this:

public interface IProjectile
{
    bool isPlayers { get; set; }
}


public class Bullet : MonoBehaviour, IProjectile
{
    ...
    public bool isPlayers { get; set; }
}


public class Cannon : MonoBehaviour, IWeapon
{
    [SerializeField] private GameObject prefab;
    ...
    public void Attack()
    {
        ...
        var instance = Instantiate ( prefab );
        var component = instance.GetComponent<IProjectile>( );
        if ( component != null )
            component.isPlayers = transform.parent.CompareTag( "Player" );
        ...
    }
}
