How to add a animation to a Player?

问题:

I'm currently making a shoot em up in monogame.

I've managed to make a constantly looping animation with my sprite but the problem is that I now don't know how to insert my animated sprite to myPlayer.

I don't want any commands only a constantly looped animation attached to myPlayer. I'm a beginner to programming so help is much appreciated.

This project is due soon so would love some help.

Game1:
        Texture2D myPlayerAnim;
        Rectangle myDestRect;
        Rectangle mySourceRect;
        Texture2D myEnemyAnim;
        Rectangle myEnemyDestRect;
        Rectangle myEnemySourceRect;
        float myElapsed;
        float myDelay = 100f;
        int myFrames = 0;

Initialize:
            myDestRect = new Rectangle(0, 0, 512, 512);
            myEnemyDestRect = new Rectangle(0, 0, 808, 608);

LoadContent: 

            myPlayerAnim = Content.Load<Texture2D>("SpriteSheetPlayerAnim");
            myEnemyAnim = Content.Load<Texture2D>("SpriteSheetEnemyAnim");

Update:    
            myElapsed += (float)aGameTime.ElapsedGameTime.TotalMilliseconds;

            if (myElapsed >= myDelay)
            {
                if (myFrames >= 3)
                {
                    myFrames = 0;
                }
                else
                {
                    myFrames++;
                }
                myElapsed = 0;
            }

            mySourceRect = new Rectangle(512 * myFrames, 0, 512, 512);
            myEnemySourceRect = new Rectangle(808 * myFrames, 0, 808, 608);

Draw: 

            mySpriteBatch.Draw(myPlayerAnim, myDestRect , mySourceRect, 
            Color.White);
            mySpriteBatch.Draw(myEnemyAnim, myEnemyDestRect, myEnemySourceRect, 
            Color.White);

Draw currently only draws out the animation because it's not attached to anything.

currently myPlayer only has a single png attached and not my animation.

Draw: 
myPlayer = new Player(TextureLibrary.GetTexture("player"), myPlayerPos, 200, new Vector2(.3f, .3f), 0, Color.White, 1000, 1);

回答1:

Based on your code you have given. I think you just need to change some things.

First, use the SpriteSheetPlayerAnim as the texture of your player directly instead of using player texture.

Then move the code of Update and Draw of player's animation to Update and Draw of Player class.

They will be like this:

public class Player
{
    //Default constructor
    public Player()
    {
        //default values for your player//for example only
        //this.hp = 100;
        //this.mp = 20;
    }

    //Constructor
    public Player(GameTime myelapsedGameTime, Texture2D texPlayer, Vector2 playerPosition, int something, Vector2 vector2ForSomething, int intFST, Color playerColor, ...)
    {
        //initialise player's attributes

    }

    public override Update(GameTime gameTime)
    {
        if (myElapsed >= myDelay)
        {
            if (myFrames >= 3)
            {
                myFrames = 0;
            }
            else
            {
                myFrames++;
            }
            myElapsed = 0;
        }
    }

    public override Draw(SpriteBatch spriteBatch)
    {
        spriteBatch.Draw(myPlayerAnim, myDestRect , mySourceRect, 
            Color.White);//for example
    }
}

Then in your Game1 class:

public class Game1 : Game
{
    Player player;
    GameTime myElapsed;

    public Game1()
    {
        //
    }

    protected override void LoadContent()
    {
        //Load your animated sprite here
        myPlayerAnim = Content.Load<Texture2D>("SpriteSheetPlayerAnim");

        player = new Player(myElapsed, myPlayerAnim, ...);//constructor with attributes here or whatever you want
    }

    protected override void Update(GameTime gameTime)
    {
        myElapsed += (float)aGameTime.ElapsedGameTime.TotalMilliseconds;
        player.Update(gameTime);
    }

    protected override void Draw(SpriteBatch spriteBatch)
    {
        player.Draw(spriteBatch);
    }
}

Hope this helps!
