我有我一直在制作的 XNA 2D 游戏,但我遇到了问题。
我的精灵正在跳过屏幕上滚动的框。精灵被 2D 摄像头跟踪,我担心摄像头会引起问题,因为它会导致滚动框在屏幕中途停止而不是继续,而且生命的数量正在迅速减少而不是一个生命当发生一次碰撞时。
这是我的精灵与移动框碰撞的代码
Rectangle fairyRectangle = new Rectangle((int)position.X, (int)position.Y, texture.Width, texture.Height);
hit = false;
for (int i = 0; i < GameConstants.TotalBoxes; i++)
{
if (scrollingBlocks.boxArray[i].alive)
{
Rectangle blockRectangle = new Rectangle((int)scrollingBlocks.boxArray[i].position.X, (int)scrollingBlocks.boxArray[i].position.Y, scrollingBlocks.boxArray[i].texture.Width, scrollingBlocks.boxArray[i].texture.Height);
if (IntersectPixels(fairyRectangle, fairyTextureData, blockRectangle, blockTextureData))
{
scrollingBlocks.boxArray[i].alive = false;
hit = true;
lives--;
scrollingBlocks.boxArray[i].alive = true;
scrollingBlocks.boxArray[i].position.X = random.Next(GameConstants.ScreenWidth);
scrollingBlocks.boxArray[i].position.Y = 570;
}
}
}
这是滚动框中的更新函数 public void Update(GameTime gameTime) {
for (int i = 0; i < GameConstants.TotalBoxes; i++)
{
boxArray[i].position.X = boxArray[i].position.X - 5;
boxArray[i].position.Y = boxArray[i].position.Y;
if (boxArray[i].position.X < 0)
{
boxArray[i].position.X = randomno.Next(GameConstants.ScreenWidth) + 700;
boxArray[i].position.Y = 570;
}
Helper.WrapScreenPosition(ref boxArray[i].position);
}
}
我希望它们从右侧屏幕开始并一直移动到 x = 0,但它们目前在 x = 400 处停止。
最后,这是我用精灵和方块绘制的地方
if (gameState == GameState.PLAYINGLEVEL3)
{
graphics.GraphicsDevice.Clear(Color.Aquamarine);
spriteBatch.Begin(SpriteBlendMode.AlphaBlend);
backgroundManager.Draw(spriteBatch);
//scrollingBlocks.Draw(spriteBatch);
spriteBatch.DrawString(lucidaConsole, "Score: " + score + " Level: " + level + " Time Remaining: " + ((int)timer / 1000).ToString() + " Lives Remaining: " + lives, scorePosition, Color.DarkOrchid);
spriteBatch.End();
spriteBatch.Begin(SpriteBlendMode.AlphaBlend, SpriteSortMode.Deferred, SaveStateMode.None, camera.transform);
scrollingBlocks.Draw(spriteBatch);
fairyL3.Draw(spriteBatch);
spriteBatch.End();
}
谢谢你的帮助!
