I'm trying to edit the properties tab of my MonoGame but when I try to it comes up with
Value cannot be null. Parameter name: val
I'm pretty new to this and I'm not sure what is causing this? Everything works as intended and I'm not getting any runtime errors.
Here is my code:
This is Game1.cs
using System;
using System.Collections.Generic;
using System.Linq;
using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Audio;
using Microsoft.Xna.Framework.Content;
using Microsoft.Xna.Framework.Graphics;

spriteBatch.Draw(PlayerRightWalk, new Rectangle(100, 100, 128, 32), Color.White);
spriteBatch.End();
base.Draw(gameTime);
}
}
}
And this is Program.cs
using System;
namespace HorrorgameMono
{
#if WINDOWS || LINUX

public static class Program

[STAThread]
static void Main()
{
using (var game = new Game1())
game.Run();
}
}
#endif
}
The project runs fine on its own, it just doesn't let me edit the properties.
I wasn't sure what was wrong, so i re-installed visual studio and now the properties show up!

I am having trouble getting XNA sound effect to load. I have tried selecting the file through cwd as well as a full static directory, but when I try to build, the sound effect still reads as null. I have triple checked that the file is in the correct place, as well as that it is included in the project, but it still goes unrecognized.

I am currently getting back in to MonoGame but for some reason I am having an issue drawing a simple sprite to the screen.
I am using VS2015 community, created a new multiplatform MonoGame project, and then right-clicked on the Content folder and added existing item to load my 'player.png' image in to the project.
I then wrote the following code to load the image and draw to the screen:
using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Graphics;
using Microsoft.Xna.Framework.Input;
namespace BulletHell
{
/// <summary>
/// This is the main type for your game.

{
GraphicsDeviceManager graphics;
SpriteBatch spriteBatch;
Texture2D playerImage;
Player player;
public Game1()
{
graphics = new GraphicsDeviceManager(this);
Content.RootDirectory = "Content";
}
/// <summary>

{
player = new Player(100, 100, playerImage);
base.Initialize();
}

playerImage = Content.Load<Texture2D>("player");
player.Image = playerImage;
}

base.Update(gameTime);
}
/// <summary>

protected override void Draw(GameTime gameTime)
{
GraphicsDevice.Clear(Color.Black);
// TODO: Add your drawing code here
spriteBatch.Begin();
spriteBatch.Draw(playerImage, new Vector2(0, 0), Color.White);
spriteBatch.End();
base.Draw(gameTime);
}
}
}
Any idea why the sprite is not being displayed?
Thanks
Upon looking at your code again I noticed that base.LoadContent(); is missing in your LoadContent method. If you re-add this it should draw it
I'm programming a Tower Defense game in XNA/Monogame and was doing just fine until i ran into this exception "FileNotFoundException" (I have it set to break when i get one of these and when I continue it won't work). It says it can't find the new images ive added. i put them in the content folder and the rootdirectory is set to Content. The old images work but the new ones won't.

Mark the new images added to the project as Build Action Content in the properties menu of the images, which is usually on the right side.
I'm currently using this code that someone recommended to combine Awesomium and XNA, however I'm having an issue... Whenever I try to draw the resulting Texture2d the component gives me, I get:
You may not call SetData on a resource while it is actively set on the GraphicsDevice. Unset it from the device before calling SetData.

What exactly am I doing wrong?
Your SpriteBatch is setting the web texture into the graphics device's first texture stage and never unsetting it. This is causing Awesomium's Draw() method to fail, because it's trying to call SetData() on a texture that's still in use.
After spriteBatch.End(), unset the texture stage:
GraphicsDevice.Textures[0] = null;

what is the error in this? this will return the Error loading "character.png". File not found.
I have created character.png and added it to my project but it too doesn't work
i use visual studio 2010 c# with
xna 4.0
Try this:
myTexture = Content.Load<Texture2D>("character");
edit: If it still doesn't work, make sure the file is set to use the correct content importer as described here: http://msdn.microsoft.com/en-us/library/bb313966.aspx.
Do this:
Texture myTexture = Content.Load<Texture2D>("character");
Why Does It Work?
The ContentManager.Load<> method accepts an asset name, not a file path. You need to click on the asset in the Solution Explorer, then find the asset name. This is the parameter for the Load<> method.
Hope this helps and good luck in the future!
