Mouse does not work!

1

I’ve been working with Monogame the past three years, and it is great. But I’ve had some difficult with mouse position. It used to work, but if I use classes, it doesn’t work. This is my test project:
Game1 class:

    GraphicsDeviceManager graphics;
    SpriteBatch spriteBatch;

    Playerclass Player;
    public Game1()
    {
        graphics = new GraphicsDeviceManager(this);
        Content.RootDirectory = "Content";
    }
    protected override void Initialize()
    {
        this.IsMouseVisible = true;
        base.Initialize();
    }
    protected override void LoadContent()
    {
        // Create a new SpriteBatch, which can be used to draw textures.
        spriteBatch = new SpriteBatch(GraphicsDevice);
        Player = new Playerclass();
        Player.LoadContent(Content);
    }
    protected override void UnloadContent()
    {
    }
    protected override void Update(GameTime gameTime)
    {
        Player.Update(gameTime);
        base.Update(gameTime);
    }
    protected override void Draw(GameTime gameTime)
    {
        GraphicsDevice.Clear(Color.CornflowerBlue);
        spriteBatch.Begin();
        //spriteBatch.Draw(Guy, Mouse.GetState().Position.ToVector2(), Color.White);
        Player.Draw(spriteBatch);
        spriteBatch.End();
        base.Draw(gameTime);
    }

Player class:

    Texture2D Guy;
    Point Position;
    public void LoadContent(ContentManager Content)
    {
        Guy = Content.Load<Texture2D>("Guy");
    }
    public void Update(GameTime gameTime)
    {
        Position = Mouse.GetState().Position;
    }
    public void Draw(SpriteBatch spriteBatch)
    {
        spriteBatch.Draw(Guy, Position.ToVector2(), Color.White);
    }

It just returns 0,0! What is the problem? Please help!

It might just be me, but that code doesn’t make sense. In your Game class you have

Player.Update(gameTime, Mouse.GetState().Position.ToVector2()); // notice the 2 arguments

but then inside your Player class you have

public void Update(GameTime gameTime) // notice there is only 1 parameter

There is something funky going on here… something you’re not sharing with us.

Whoops! Sorry, wrong source code!

I can’t see any issues with that. Maybe try zipping up the project, and sharing that.

Ok, I can send you my project!

Mouse position just returns 0,0. And leftbutton is always false. I don’t know if it is just with my computer, if so, I don’t know the problem. I have installed monogame over and over again, but It still doesn’t work. It has been happening for one year.

Oh boy. You’re just a silly sausage @anon88365101.

You’re “Playerclass” is inheriting “Game1”.

public class Playerclass : Game1

Because of that, you’d need to “override” your Update method in the “Playerclass” class.

But that’s not the point, you shouldn’t have a player inheriting from Game1. It just doesn’t make sense.

When you inherit think of the words “is a”. So:
Player is a Game1 - no. No it’s not.

Also you should rename your class from “Playerclass” to “Player”.

Just to be clear. You need:

public class Playerclass

Not:

public class Playerclass : Game1

OMG! Thank you so, so much! Thank you! I used to inherit Game1 because of some public variables! Do you know another way to share public variables? Anyway, thank you so, so much! You are a lifesaver!

Try passing Game1 through the constructor.

Playerclass.cs:

private Game1 _game1;
public Player(Game1 game1)
{
  _game1 = game1;
}

Game1.cs:

Player = new Playerclass(this);

You should then be able to use the the _game1 field to access those properties.

Thank you again! You’ve helped me a lot!

Would now be a good time to ask you to become a Patreon? :wink:

Nah, I’m joking. Happy to help! :slight_smile:
