Subject: try to convert CCtexture2d to Attachment

Nate wrote

Your CCTextureAtlas problem was because you weren't retaining the instance, so it gets disposed by the pool.

Your next problem was that you UVs were 0,0,0,0. You were using:

    float u = region-&gt;x / size.width;
    float u2 = (region-&gt;x + region-&gt;width) / size.width;
    float v = region-&gt;y / size.height;
    float v2 = (region-&gt;y + region-&gt;height) / size.height;

But you haven't set region x/y/width/height yet, so you get zeros and nothing displays.

Here is the fixed method:

-(RegionAttachment*) regionWithTexture2d:(CCTexture2D*)tex2d name:(NSString*)_name{
    CCTextureAtlas *tex = &#91;&#91;CCTextureAtlas alloc&#93; initWithTexture:tex2d capacity:128&#93;;
    AtlasPage *page = AtlasPage_create(&#91;_name UTF8String&#93;);
    page-&gt;rendererObject = tex;
    

page-&gt;width = tex2d.contentSizeInPixels.width;
page-&gt;height = tex2d.contentSizeInPixels.height;

AtlasRegion *reg = AtlasRegion_create();
reg-&gt;page = page;

RegionAttachment *region = RegionAttachment_create(&#91;_name UTF8String&#93;);
region-&gt;rendererObject = reg;

CGSize size = tex2d.contentSizeInPixels;
float u = 0;
float u2 = 1;
float v = 0;
float v2 = 1;
RegionAttachment_setUVs(region,u,v,u2,v2,0);

region-&gt;regionOffsetX = 0; // zero if not doing whitespace stripping
region-&gt;regionOffsetY = 0;
region-&gt;regionWidth = size.width;
region-&gt;regionHeight = size.height;
region-&gt;regionOriginalWidth = region-&gt;regionWidth; // same if not doing whitespace stripping
region-&gt;regionOriginalHeight = region-&gt;regionHeight;

region-&gt;x = 0;
region-&gt;y = 0;
region-&gt;scaleX = 1;
region-&gt;scaleY = 1;
region-&gt;rotation = 0;
region-&gt;width = size.width;
region-&gt;height = size.height;
spRegionAttachment_updateOffset(region);

return region;
}

Result is an icon instead of a head:

Hi Nate.
I have a similar problem as the one described by the OP, however; I want to convert a Texture2D to an RegionAttachment in C# - XNA. I am unfortunately not very good at Objective C and I am therefore not able to translate the code :S Can you possibly help me?
