Sprite Issues!!! Helpa Me Please

[Berty]

ok, well, what is going on here is im porting my zGuitarTuner to zhd. My Problem is, that the sprite is not drawing properly.

In my original version (for zsd that work fine) i have one long sprite of many chord charts, that i scroll through by adding to the x value of the new vector

in my zhd version i have the exact same setup (scrolling method a lil different cause it is easier to code) but my sprite seems to just smear off into the distance?

This video pretty much sums it up!

YouTube- ahhh.wmv

Would you mind posting the drawing code?

[Red Sky]

have you done a GraphicsDevice.Clear(Color.Black) before drawing your sprite?

[Berty]

@ Red Sky, yes, yes i have

um its a long Draw so... ill post what is needed

protectedoverridevoid Draw(GameTime gameTime)
{
GraphicsDevice.Clear(Color.Black);

spriteBatch.Begin(SpriteBlendMode.AlphaBlend);

if (screen == 20)
{
if (turndevice == true)
{
spriteBatch.Draw(turndevicescreen, viewportRect, Color.White);
}
if (turndevice == false)
{
spriteBatch.Draw(A1, newVector2(100, 60 + noteposition), Color.White);

spriteBatch.DrawString(font, "A", newVector2(200, 63),Color.White,
(float)Math.PI / 2, newVector2(0, 0), 1.0f, SpriteEffects.None, 0.0f);

spriteBatch.Draw(leftarrow, leftarrowRect, Color.White);

spriteBatch.Draw(rightarrow, rightarrowRect, Color.White);

}
}
spriteBatch.End();
base.Draw(gameTime);
}

how do you update note position after the end of the list has been reached? You might simply be drawing the same note over and over again, but the position changes slightly so it looks like it 'blurs' when it's really just a ton of the same image drawn again.

Edit:

upon watching the video a second time, this doesn't appear to be what happens.

[Berty]

um, well its just the same, it just keeps moving the sprite to the left or right even outside of the viewportrect

[Tiptup300]

viewportRect's width must be bigger then the textures.... I guess the HD handles that differently.

[Berty]

I don't think so, cause I can still scroll through most of the sprite that is outside of the viewportrect!

[dnchattan]

Is it possible that the sprite went over the texture size limit for the ZuneHD? Try checking the width/height attributes of the actual texture in the debugger and see if they are correct.

[Berty]

Yeah, that's what I was wondering, because I'm using the exact same size as the ones I used that worked in my last version ( on standered Zunes )

[Tiptup300]

wait is the texture drawing part the

"spriteBatch.Draw(A1, newVector2(100, 60 + noteposition), Color.White);" bit?

Because that doesn't make sense... it wouldn't be moving at all.

[Berty]

Yeah........ That's the bit!

[Tiptup300]

Do you rotate the screen at all?

[Berty]

um.... what? I do have the Zune tilted, but not the sprite

[Tiptup300]

How does the sprite move, is that code the exact code you use or was it just like paraphrased? Because that code wouldn't work at all there.

[Berty]

Uh.... thats the DRAW code........ the update Gametime code is simply if i press in those arrows, noteposition += 4; or noteposition -= 4;

[Tiptup300]

I gather that, but

spriteBatch.Draw(A1, newVector2(100, 60 + noteposition), Color.White);

That wouldn't even compile first off (newVector2), and it would move it vertically not horizontally...

[DiNoGames]

It actually moves vertically... he just turned the Zune Device so that it looks horizontally again...

I asked him if he rotated the screen....

[DiNoGames]

You can see it in the video.
Maybe he thought you mean turning the screen by code using a rendertarget or something (landscape mode).
