Drawing sprites with sprite.draw2D in vb.net

[shamuse]

Hey,

 

So I've recently begun working with directx in vb.net but Ive run in to a small problem. I can only render sprites that have power of 2 dimensions. I am aware that the texture of the sprite has to be based off an image with power of 2 dimensions, but Im fairly sure that there must be a way to render the spirte itself in something other than power of 2 dimensions using sprite.draw2d.

 

It would be great if any of you could help me.

 

Thanks!:)

I have never tried, I didn't even know that you couldn't.

 

I'm curious why you need to though? Whats the reason for it?

[shamuse]

well, maybe I'm missing something, but if I can only render sprites with power of 2 dimensions there's only a certain amount of sprite sizes I can pick from. So I cant get exact sprite sizes.

[Nate Bross]

You should be able to Scale the sprites using floating point values to get them exactly the size you want.

I'm still a little confused. As far as I can tell the only parameters you can plug in to either textureloader.fromfile or sprite.draw2D are integers.

 

Also, I should have mentioned this earlier, but if I try to scale it by plugginig in numbers that are not powers of 2 in the parameters for length and width in the textureloader.fromfile function it automatically rounds up to the length/width to the next power of two.

The sprite.Draw2D method has overloads that allow you to specify the size it will be rendered - you do not need to scale the texture yourself.

[Nate Bross]

Yes, PD is correct: something roughly like this should work for you.

sprite.Begin(SpriteFlags.None);

sprite.Draw2D(texture, Rectangle.Empty, Rectangle.Empty,
             new Point(5.0f, 5.0f), Color.White);
sprite.End();

Thanks! It works now:)
