Title: VertexArray, setTextureRect and setRepeated
Post by: madcat on September 11, 2014, 09:10:11 am

Hi,

I was wondering if there's a way to associate a repeated texture taken from a tilemap to a VertexArray.
I'm designing asteroids as non convex triangle based objects and I have a sort of texmap with different repeatable rock textures + some sticker-style graphics to overlay on my polygonal asteroids (extra craters, space base, smashed alien...)


I don't seem to find a straightforward way to do it....
is there a way to fix a textureRectangle when assigning the texture at the state level?

state.texture = ??

thx

Your question seems to be: "can you repeat texture rects instead of only being able to repeat the entire texture" and, after a quick scan of the docs, it doesn't look like that is possible.

Btw. that's how OpenGL works. You can ignore, clamp or repeat texture coordinates if they are lower than 0.0 or higher than 1.0 (normalized). You might want to tailor yourself a little shader to repeat sub textures.
