Multiple errors that keep appearing while running my code.

Recommended Posts

I have attached my project in a .zip file if you wish to run it for yourself.

I am making a simple 2d top-down game and I am trying to run my code to see if my window creation is working and to see if my timer is also working with it. Every time I run it though I get errors. And when I fix those errors, more come, then the same errors keep appearing. I end up just going round in circles.  Is there anyone who could help with this? 

 

Errors when I build my code:

You are using `std::string` in Renderer.h but don't include `Common.h` (or "cstring")

Just add the missing #include.

Thank you. 

I now have one error left to deal with.. Would this error be because I have no main() function?

Yes, you need either `main()` (if this is a console application) or `WinMain` (if this a windows application)

I am using GLFW and GLEW frameworks.

I have implemented the WinMain function as this is a windows application in Renderer.cpp: 

#include <GL/glew.h>
#include <GLFW/glfw3.h>
#include "Renderer.h"
#include "Timer.h"
#include "Windows.h"


#include <iostream>
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPWSTR lpCmdLine, int nShowCmd)
{
	namespace Game
	{
		GLFWwindow* window;

		/* Initialize the library */


		Rendering::Rendering()
		{



			mClock = new Clock;
		}

		Rendering::~Rendering()
		{
			shutdown();
		}
		bool Rendering::initialize(uint width, uint height, bool fullscreen, std::string window_title)
		{
			if (!glfwInit()) {
				return -1;
			}


			/* Create a windowed mode window and its OpenGL context */
			window = glfwCreateWindow(640, 480, "Hello World", NULL, NULL);
			if (!window)
			{
				glfwTerminate();
				return -1;
			}

			/* Make the window's context current */
			glfwMakeContextCurrent(window);

			glViewport(0, 0, (GLsizei)width, (GLsizei)height);
			glOrtho(0, (GLsizei)width, (GLsizei)height, 0, 1, -1);

			glMatrixMode(GL_PROJECTION);
			glLoadIdentity();

			glfwSwapInterval(1);
			glEnable(GL_SMOOTH);
			glEnable(GL_DEPTH_TEST);
			glEnable(GL_BLEND);
			glDepthFunc(GL_LEQUAL);
			glHint(GL_PERSPECTIVE_CORRECTION_HINT, GL_NICEST);
			glEnable(GL_TEXTURE_2D);
			glLoadIdentity();

			return true;
		}


		bool Rendering::render()
		{
			/* Loop until the user closes the window */
			if (!glfwWindowShouldClose(window))
				return false;
			/* Render here */
			mClock->reset();

			glfwPollEvents();

			if (mClock->step())
			{
				glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

				glfwSwapBuffers(window);

				mClock->update();
			}

			return true;
		}

		void Rendering::shutdown()
		{

			glfwDestroyWindow(window);
			glfwTerminate();
		}

		GLFWwindow* Rendering::getCurrentWindow()
		{
			return window;
		}

	}
}

 

I however have multiple errors again as a result:

What happened to your other thread I was helping you on? https://www.gamedev.net/forums/topic/696518-game-loop-and-game-physics  Your thread seems to have been removed or hidden?

When you're getting these warnings and errors you need to work from the top down. I wont go over the warnings, but your first error is telling you that: error C2731: 'WinMain': function cannot be overloaded

You problem looks like you're using WinMain and trying to have LPWSTR which means 'long pointer to wide string'. If you look up WinMain it doesn't accept this type. WinMain takes a char* for lpCmdLine, you'll need to use wWinMain which takes wchar_t* as LPWSTR (typedef wchar_t* LPWSTR, *PWSTR;)

Based on what I've seen in your other thread and this one, I would strongly suggest picking up a good C++ book before moving forward in Game Programming. You're going to be running into problem after problem if you don't have a solid foundation.

C++ Primer

Accelerated C++

Programming: Principles and Practice Using C++

I wish you the best in your learning.

I removed namespace after adding the new wWinMain() and those errors went away. However, I now have some more error.

I understand that the top error is due to the fact mClock is undeclared and that the error has come about as a result of me removing namespace from all my .cpp and .h 's.  

How would I go about fixing this? Would I use an example given in the link below?

Your first error: error C2065: 'mClock': undeclared identifier is because you have: mClock = new Clock; This is not how you declare a new class object because mClock has nothing associated with it. Before using any pointers you should have an understanding about new and delete, as well as dynamic memory allocation. You can also look into shared_ptr.

The rest of your errors are self explanatory from the description provided in your compiler log.
