Cannot implicitly convert type 'void' to 'bool'

For some reason when i try to call for a method in my if statement it gives me the error " Cannot implicitly convert type ‘void’ to ‘bool’". How can i fix this??

Here is my code:

public class Player : MonoBehaviour {

	private bool checkpointEnabled = false;
	public static Vector3 checkpoint;
	public static Vector3 respawn;

	void Start () {
		spawn = transform.position;
		checkpoint = gameObject.transform.position;
		respawn = spawn;
	}
	

	void FixedUpdate () {
		
		if (checkpointEnabled)
		{
			respawn = checkpoint;
		}

		if (Die())
		{
			if(checkpointEnabled)
			{
			transform.position = respawn;
			}
		}
	
	}
	
	void Die()
	{
		Instantiate(deathParticles, transform.position,Quaternion.Euler(0,0,0));
		transform.position = spawn;
	}
}

This is the part that is giving me the error.

if (Die())
     {
         if(checkpointEnabled)
         {
         transform.position = respawn;
         }

Your Die function returns void, not bool, so you can’t use it in an if statement.

Your Die function also doesn’t do anything to check if a player should die, it just instantiates particles and sets the position.
