Normally we either create a sprite from a sprite frame, a file, or a texture by doing something like:
Sprite* foo = Sprite::create(filename);
How can one create a white square of specified dimensions without using DrawNode or passing a file to a sprite ?
I know this is possible, because I stumbled upon another post which described how to do it, but neglected to book mark it, and the post doesn't show up in search results..
Something like this:
auto dataLen = width * height * bitsPerPixel * sizeof(unsigned char);
auto data = static_cast<unsigned char*>(malloc(dataLen));
memset(data, 255, dataLen);
auto texture = new Texture2D();
texture->initWithData(data, dataLen, Texture2D::PixelFormat::RGBA8888, width, height, Size(width, height));
auto sprite = Sprite::createWithTexture(texture);
