Whenever I run the program I keep on getting the eroor: Level.cs(15,21): error CS0161: `TreehouseDefense.Level.Play()': not all code paths re turn a value
Here is the code the error refers to. Could I get any help? I dont understand my code is exactly as it appears in the video.
public bool Play()
{
//Run until all invaders are dead or an invader reaches the end.
int remainingInvaders = _invaders.Length;
while(remainingInvaders > 0)
{
//Each tower has opportunity to fire on invaders
foreach(Tower tower in Towers)
{
tower.FireOnInvaders(_invaders);
}
//Counr and move iinvaders that are still active.
remainingInvaders = 0;
foreach(Invader invader in _invaders)
{
if(invader.IsActive)
{
invader.Move();
if(invader.HasScored)
{
return false;
}
remainingInvaders++;
}
}
}
}

231,198 PointsYour function is defined to return a bool, which it does when it finds an invader that "HasScored".
But if it does not, it currently doesn't return anything, and that's causing the error.
