I'm doing a simple Tower Defense game on XNA and I'm having some trouble. I have an enemy sprite that should be green, the image is correct, but when I insert it on the program it appears all black, but in the right shape. Here's my code (sorry that it's a mess):
namespace MicroDefense
{
public class Game1 : Microsoft.Xna.Framework.Game
{
GraphicsDeviceManager graphics;
SpriteBatch spriteBatch;
enum GameState
{
MainMenu,
Options,
Playing,
}
GameState CurrentGameState = GameState.MainMenu;
// Screen Adjustments
int screenWidth = 800, screenHeight = 600;
cButton btnPlay;
Level level = new Level();
WaveManager waveManager;
Player player;
GUI.Button arrowButton;
GUI.Button spikeButton;
GUI.Button slowButton;
GUI.Toolbar toolBar;
public Game1()
{
graphics = new GraphicsDeviceManager(this);
Content.RootDirectory = "Content";
// The width of the level in pixels
graphics.PreferredBackBufferWidth = level.Width * 32;
// The height of the toolbar + the height of the level in pixels
graphics.PreferredBackBufferHeight = 32 + level.Height * 32;
graphics.ApplyChanges();
IsMouseVisible = true;
}
protected override void Initialize()
{
base.Initialize();
}
protected override void LoadContent()
{
spriteBatch = new SpriteBatch(GraphicsDevice);
// Screen stuff
graphics.PreferredBackBufferWidth = screenWidth;
graphics.PreferredBackBufferHeight = screenHeight;
graphics.ApplyChanges();
IsMouseVisible = true;
btnPlay = new cButton(Content.Load<Texture2D>("Button"), graphics.GraphicsDevice);
btnPlay.setPosition(new Vector2(350, 300));
Texture2D topBar = Content.Load<Texture2D>("tool bar");

level.AddTexture(grass);
level.AddTexture(path);

healthTexture);
// The "Normal" texture for the arrow button.

Texture2D slowHover = Content.Load<Texture2D>("GUI\\Slow Tower\\slow hover");
// The "Pressed" texture for the slow button.
Texture2D slowPressed = Content.Load<Texture2D>("GUI\\Slow Tower\\slow pressed");
// Initialize the arrow button.
arrowButton = new GUI.Button(arrowNormal, arrowHover,
arrowPressed, new Vector2(0, level.Height * 32));
// Initialize the spike button.
spikeButton = new GUI.Button(spikeNormal, spikeHover,
spikePressed, new Vector2(32, level.Height * 32));
// Initialize the slow button.
slowButton = new GUI.Button(slowNormal, slowHover,
slowPressed, new Vector2(32 * 2, level.Height * 32));
//arrowButton.Clicked += new EventHandler(arrowButton_Clicked);

Edit1:The sprite has the right shape but the color is black.
Edit2: Here's the wave manager:
public class WaveManager
{
private int numberOfWaves; // How many waves the game will have
private float timeSinceLastWave; // How long since the last wave ended
private Queue<Wave> waves = new Queue<Wave>(); // A queue of all our waves
private Texture2D enemyTexture; // The texture used to draw the enemies
private bool waveFinished = false; // Is the current wave over?
private Level level; // A reference to our level class.
public Wave CurrentWave // Get the wave at the front of the queue
{
get { return waves.Peek(); }
}
public List<Enemy> Enemies // Get a list of the current enemeies
{
get { return CurrentWave.Enemies; }
}
public int Round // Returns the wave number
{
get { return CurrentWave.RoundNumber + 1; }
}
public WaveManager(Player player, Level level, int numberOfWaves,
Texture2D enemyTexture, Texture2D healthTexture)
{
this.numberOfWaves = numberOfWaves;
this.enemyTexture = enemyTexture;
this.level = level;
for (int i = 0; i < numberOfWaves; i++)
{
int initialNumerOfEnemies = 6;//Número de inimigos por wave <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
int numberModifier = (i / 6) + 1;
// Pass the reference to the player, to the wave class.
Wave wave = new Wave(i, initialNumerOfEnemies * numberModifier,
player, level, enemyTexture, healthTexture);
waves.Enqueue(wave);
}
StartNextWave();
}
private void StartNextWave()
{
if (waves.Count > 0) // If there are still waves left
{
waves.Peek().Start(); // Start the next one
timeSinceLastWave = 0; // Reset timer
waveFinished = false;
}
}
public void Update(GameTime gameTime)
{
CurrentWave.Update(gameTime); // Update the wave
if (CurrentWave.RoundOver) // Check if it has finished
{
waveFinished = true;
}
if (waveFinished) // If it has finished
{
timeSinceLastWave += (float)gameTime.ElapsedGameTime.TotalSeconds; // Start the timer
}
if (timeSinceLastWave > 10.0f) // If 10 seconds has passed Tempo entre waves <<<<<<<<<<<<<
{
waves.Dequeue(); // Remove the finished wave
StartNextWave(); // Start the next wave
}
}
public void Draw(SpriteBatch spriteBatch)
{
CurrentWave.Draw(spriteBatch);
}
}
WaveManagersource code? Looks like this class handles enemy drawing and root of the problem might be there. But still, try to avoid posting useless info. – CodingFeles
