XNA vs MonoGame GameTime?

1

Hi,

I have stumbled upon a problem when i created a dll-library in VS2013 with MonoGame.

The code for the DLL:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml.Serialization;

using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Content;
using Microsoft.Xna.Framework.Graphics;

namespace AtriLib2.ScreenManager
{
    public class GameScreen
    {
        protected ContentManager Content;
        [XmlIgnore]
        public Type Type;

        public string XmlPath;

        public bool HasTitle;
        public string Title;

        public GameScreen()
        {
            Type = this.GetType();
            XmlPath = "";
            Title = "";
            HasTitle = false;
        }

        public virtual void LoadContent()
        {
            Content = new ContentManager(ScreenManager.Instance.Content.ServiceProvider, "Content");
        }

        public virtual void Unload()
        {
            Content.Unload();
        }

        public virtual void Update(GameTime gameTime)
        {

        }

        public virtual void Draw(SpriteBatch spriteBatch)
        {

        }
    }
}

So now i wanted to test if it was backward compatible, i created a project in VS2010

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Input;
using Microsoft.Xna.Framework.Graphics;
using AtriLib2;
using AtriLib2.ScreenManager;
using AtriLib2.TileMap;

namespace TestGame.Screens
{
    public class GameplayScreen : GameScreen
    {
        Map map;

        public GameplayScreen()
        {
            XmlPath = "Load/Screens/Gameplay.xml";
        }

        public override void LoadContent()
        {
            base.LoadContent();
            AXMLSerializer<Map> mapLoader = new AXMLSerializer<Map>();
            map = mapLoader.Load("Load/Map/Map1.xml");
            map.LoadContent(Content, Game1.monitor.ScreenRectangle);
        }

        public override void Unload()
        {
            base.Unload();
            map.Unload();
        }

// This method gets the error
        public override void Update(GameTime gameTime)
        {
            base.Update(gameTime);

            if (AInput.KeyDown(Keys.W))
                map.Camera.Move(Direction.Up);
            else if (AInput.KeyDown(Keys.S))
                map.Camera.Move(Direction.Down);

            if (AInput.KeyDown(Keys.A))
                map.Camera.Move(Direction.Left);
            else if (AInput.KeyDown(Keys.D))
                map.Camera.Move(Direction.Right);

            if (AInput.KeyPressed(Keys.Z))
                map.Camera.ZoomOut();
            else if (AInput.KeyPressed(Keys.X))
                map.Camera.ZoomIn();
            else if (AInput.KeyPressed(Keys.C))
                map.Camera.Zoom = A2DCamera.DEFAULT_ZOOM;

            map.Update(gameTime);
        }
// This method also gets the error
        public override void Draw(SpriteBatch spriteBatch)
        {
            spriteBatch.Begin(SpriteSortMode.Deferred, BlendState.AlphaBlend, SamplerState.PointClamp, null, null, null, map.Camera.Transformation);
            base.Draw(spriteBatch);
            map.Draw(spriteBatch);
            spriteBatch.End();
        }
    }
}

But in the 2010 project, im getting a ‘No suitable method found to override’
So my question is, is the GameTime object different in XNA 4.0 compared to MonoGames version?

What method was it?

As far as we know GameTime is 100% accurate to XNA4.

It’s the Update() method where i am getting the error, it really confuses me.
Can it be that i compiled the DLL in VS2013 and using it in VS2010?

But if what you say, XNA4 GameTime is the same in MonoGame i don’t see a problem :confused:

EDIT:
The project works fine VS2013, all code etc and i use the same code in the VS2010 project, gonna try mess around abit more with it see if i can solve it. :slight_smile:

I also update the entire CS file from the VS2010 project

I Solved the problem, you can delete this post if you like.
What i had done was install VS2010 after MonoGame was installed, thus, i never had the MonoGame templates, so i just created a XNA Framework project, not a MonoGame project. After i reinstalled MonoGame, i got the prjoject to run just fine :slight_smile: Thanks for the reply though!
