Setting/Organizing Game Objects/Assets

Hello everyone, i am trying to make a game similar to Battle tank.
The Tanks and objects will move inside the black texture.

  • First, I want to set all objects/assets inside the game environment to become responsive(like if user changes the game window size manually, then all it contains should resize according to it). I added some lines for it, but not working for game objects(ex : tank).

  • Secondly, I want to make all object’s measurement’s perfect, so while using them together will not create any issue. Example the tank is perfectly moving between the wall and boundary(in below image)

Here is my Game1.cs upto now :
using System;
using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Graphics;
using Microsoft.Xna.Framework.Input;

namespace Tanks //Test5
public class Game1 : Game
GraphicsDeviceManager graphics;
SpriteBatch spriteBatch;
Color backgroundColor = Color.DarkGray;

    Texture2D gameSpace;

    // this is probably not required i do something similar its fine i guess.
    GameContent gameContent; // Creating game content object

    private Tank tank;
    private Bricks bricks;
    private Eagle eagle;
    private int screenWidth = 1280;
    private int screenHeight = 720;

    // Controls
    private MouseState oldMouseState;
    private KeyboardState oldKeyboardState;

    public Game1()
        graphics = new GraphicsDeviceManager(this);
        Content.RootDirectory = "Content";

        graphics.PreferredBackBufferWidth = screenWidth;
        graphics.PreferredBackBufferHeight = screenHeight;

        this.IsMouseVisible = true;
        Window.AllowUserResizing = true;
    protected override void Initialize()

    protected override void LoadContent()
        // Create a new SpriteBatch, which can be used to draw textures.
        spriteBatch = new SpriteBatch(GraphicsDevice);

        // one time creation this should also be disposed in unload now.
        gameSpace = GetSetDataCreatedTexture(graphics, (screenWidth - 280), (screenHeight - 70)); // 1000, 650

        // TODO: use this.Content to load your game content here
        gameContent = new GameContent(Content);

        // update screen width and height when you resize the window this goes with AllowUserResizing.
        Window.ClientSizeChanged += CallMeWhenTheUserResizesTheWindowHimself;

        // Getting Screen Width and Height from GraphicsAdapter.DefaultAdapter.CurrentDisplayMode
        screenWidth = GraphicsAdapter.DefaultAdapter.CurrentDisplayMode.Width;
        screenHeight = GraphicsAdapter.DefaultAdapter.CurrentDisplayMode.Height;

        //create game objects

        // Tank
        int tankX = (screenWidth) / 2; //we'll center the tank on the screen to start
        int tankY = screenHeight / 2;  //tank will be 100 pixels from the bottom of the screen
        tank = new Tank(tankX, tankY, screenWidth, screenHeight, spriteBatch, gameContent);  // Create Tank

        // Bricks
        int bricksX = (screenWidth) / 2;
        int bricksy = (screenHeight) / 2;
        bricks = new Bricks(bricksX, bricksy, Color.White, spriteBatch, gameContent);

        // Eagle
        eagle = new Eagle(bricksX, bricksy, Color.White, spriteBatch, gameContent);

    // this is chained to the callback Window.ClientSizeChanged
    public void CallMeWhenTheUserResizesTheWindowHimself(object sender, EventArgs e)
        screenWidth = GraphicsDevice.Viewport.Width;
        screenHeight = GraphicsDevice.Viewport.Height;
        gameSpace = GetSetDataCreatedTexture(graphics, (screenWidth - 280), (screenHeight - 70)); // 1000, 650
        Console.WriteLine("---- Height : " + screenHeight);
        Console.WriteLine("---- Width : " + screenWidth);

    // if you must set this from a specific need once conditionally from update.
    // calling this everyframe will also lock or crash your app.
    public void ManuallyChangeTheBackBuffer(int width, int height)
        graphics.PreferredBackBufferWidth = width;
        graphics.PreferredBackBufferHeight = height;
        screenWidth = GraphicsDevice.Viewport.Width;

        Console.WriteLine("---- CurrentDisplayMode Height : " + GraphicsDevice.Adapter.CurrentDisplayMode.Width);
        Console.WriteLine("---- CurrentDisplayMode  Width : " + GraphicsDevice.Adapter.CurrentDisplayMode.Height);

    protected override void UnloadContent()
        // TODO: Unload any non ContentManager content here
        if (gameSpace != null)
            if (gameSpace.IsDisposed != true)

Hi @ank_rawat and welcome to the forums,

Take a look here:

Happy Coding!

Hi, thanks for the reply.
Is there any simple implementation for a beginner? Sorry, but i am not able to understand the approach clearly.

Try this then:

Honesty, I recommend getting some XNA books if I were you.

Few years ago when I decided to start learn how to make a simple game.
I had the game in my mind what I want to do. Started googling… found monogame, googling more studying basic things c#, followed few tutorials…

…It took about a year of reading/learning until I started to do that game what was plan at the begining.

My advice to you is start from the tutorials. It is much easier to start that own project with some basic knowledge of how things work.


Sure @tunkio.
Can you suggest me some good tutorial’s and opensource code’s to play with?

google: monogame tutorial, monogame beginner… gives plenty of result.
There is lot of similar questions/links/topics… most of XNA tutorials should work fine.

try for start… Learning how to use MonoGame
