For a college project I'm making in monogame, I have a dictionary with references to all the different entities in my game. The hierachy I'm using is: Component <---- Entity <---- Enemy <---- Sawblade. I am defining the references like so:
{
"Sawblade",
new Sawblade(new Dictionary<string, Animation>
{
{"Moving", AllAnimations["SawBladeMoving"] },
}, 100f, -1, 2)
},
In the main gameplay update method I am looping through all the current entities with:
foreach (Component entity in entities[game.currentDungeon.currentFloor])
{
entity.Update(_gametime);
}
So far this has worked very well, it updates the enemies with the update method in the enemy class and updates other entities with their own update class. However I need the sawblade class to run this update method and not the update method in the general enemy class:
public override void Update(GameTime gameTime)
{
if (GameManager.CheckTileCollisions(new Rectangle(Edge.X + (int)Velocity.X, Edge.Y, Edge.Width, Edge.Height))) Velocity = new Vector2(-Velocity.X, Velocity.Y);
if (GameManager.CheckTileCollisions(new Rectangle(Edge.X, Edge.Y + (int)Velocity.Y, Edge.Width, Edge.Height))) Velocity = new Vector2(Velocity.X, -Velocity.Y);
animationManager.LateUpdate(gameTime);
}
The sawblade update method (What should run)^
public override void Update(GameTime gameTime)
{
if(Health <= 0) GameManager.RemoveEntity(this);
if(Target is not null)
{
// TEMP PATHFINDING
if(Target.Position.X == Position.X) Velocity = new Vector2(0, 0);
else if (Target.Position.X > Position.X) Velocity = new Vector2(1, 0);
else Velocity = new Vector2(-1, 0);
if (Target.Position.Y == Position.Y) Velocity = new Vector2(Velocity.X, 0);
else if (Target.Position.Y > Position.Y) Velocity = new Vector2(Velocity.X, 1);
else Velocity = new Vector2(Velocity.X, -1);
}
}
The enemy update method (What is running)^
I don't understand why for every other entity the program runs the highest level override but for this class specifically it acts as if the sawblade override isn't even there. Does anybody have any ideas on what could be causing this?
I have tried:
foreach (Component entity in entities[game.currentDungeon.currentFloor])
{
if (entity is Sawblade) ((Sawblade)entity).Update(_gametime);
else entity.Update(_gametime);
}
to see if the error is that i doesn't understand the entity is of the sawblade type however it still refuses to acknowledge the override.

}
Found the solution, it was due to when adding the entity to the entities list I called the clone() method which wasn't overriden in sawblade, so it was only returning the sawblade as type enemy.
Added the method to the sawblade and it fixed the problem
