Changes to the VulkanContext class

To get access to SwapChain, RenderPass, and the current command buffer, we will add the following functions to the VulkanContext.h file under the VulkanContext class in the public section:

   void drawBegin(); 
   void drawEnd(); 
   void cleanup(); 
 
   SwapChain* getSwapChain(); 
   Renderpass* getRenderpass(); 
   VkCommandBuffer getCurrentCommandBuffer();  

Then, in the VulkanContext.cpp file, add the implementation for accessing the values:

SwapChain * VulkanContext::getSwapChain() { 
 
   return swapChain; 
} 
 
Renderpass * VulkanContext::getRenderpass() { 
 
   return renderPass; 
} 
 
VkCommandBuffer VulkanContext::getCurrentCommandBuffer() { 
 
   return curentCommandBuffer; 
}
