Typo in Index buffer Section

[zixin96]

Hello, I've found some inconsistencies between the text and the source code in the index buffer section.

1. Using an index buffer for drawing involves two changes to createCommandBuffers. 

   In the source code, we made changes to recordCommandBuffer instead of createCommandBuffers.

2. The text shows

   vkCmdBindVertexBuffers(commandBuffers[i], 0, 1, vertexBuffers, offsets);
   vkCmdBindIndexBuffer(commandBuffers[i], indexBuffer, 0, VK_INDEX_TYPE_UINT16);
   vkCmdDrawIndexed(commandBuffers[i], static_cast<uint32_t>(indices.size()), 1, 0, 0, 0);

   , but the source code shows:

   vkCmdBindVertexBuffers(commandBuffer, 0, 1, vertexBuffers, offsets);
   vkCmdBindIndexBuffer(commandBuffer, indexBuffer, 0, VK_INDEX_TYPE_UINT16);
   vkCmdDrawIndexed(commandBuffer, static_cast<uint32_t>(indices.size()), 1, 0, 0, 0);

Thanks, Zixin

Thanks for reporting. I've fixed this and a bunch of other inconsistencies.
