I have a simple question, I am trying to make a huge game for Windows Phone, but I still have an important bottleneck / problem / poor performance.
I used a mango profiler, but I did not see any problems, imposed it using only 10% of the processor on my phone.
Let me show you this problem.
This is my update.
protected override void Update(GameTime gameTime) { if (TouchPanel.IsGestureAvailable) { var gs = TouchPanel.ReadGesture(); switch (gs.GestureType) { case GestureType.FreeDrag: Position += gs.Delta; break; } } base.Update(gameTime); }
This is my drawing, where the map is 20x15 Texture2D
protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.CornflowerBlue); spriteBatch.Begin(); spriteBatch.Draw(map, Position, null, Color.Red, 0f, Vector2.Zero, 1f, SpriteEffects.None, 1f); spriteBatch.End(); base.Draw(gameTime); }
The problem is that DRAW seems to be too slow for UPDATE or some sort of.
Example:
1) I drag the screen to the right, very slowly → the texture of the map moves correctly to the right
2) I drag the screen to the right and then to the left, pretty quickly → the texture of the map moves correctly to the right, but has a slight lag when moving to the left, as if it is still moving to the right ..
3) I drag the screen in a circular circle in 1 second → well, the map needs 3 seconds to make the movement circular.
What am I doing wrong?
Should I show you a YouTube video?
Thank you very much! Luke
