问题
Is it possible to tile an image in XNA so that it fills the entirety of a rectangle? I've tried Googling the subject, but I can't find anything that seems to work (I'm probably missing something obvious though). I found this MSDN page, but I can't seem to get it to work. Here's my code:
spriteBatch.Begin(SpriteSortMode.Deferred, null, SamplerState.LinearWrap, null, null);
But this just stretched the texture to fill the rectangle, not tile it. Any help is appreciated. Thanks in advance.
回答1:
The wrap sampler states indicate that texture coordinates that fall outside of the normal 0-1 range will be wrapped. If you're calling Draw() with a null source rectangle, then your texture coordinates are always going to be from exactly 0 to exactly 1.
Try calling Draw() with a source rectangle that's bigger than the texture. Twice as big should tile it twice, four times as big should tile it four times, etc.
