SDL Load image using multiple classes and files - c++

Question

I've been using SDL for a little awhile and following Lazy Foo's tutorials. I have no problem loading images, animating sprites etc... but when I attempt to separate functions into different header files I'm unable to load an image.
I've looked about for on the internet for a few days now but haven't found an answer.
Sprite.cpp
#include "Sprite.h"
#include "Globals.h"
using namespace Globals;
Graphics sprite;
Sprite::Sprite(){}
bool Sprite::load()
{
bool success = true;
if(!sprite.loadImage("C:/SDL_Project/bin/Debug/PNG_transparency_demonstration_1.png"))
{
printf("Failed to load image!\n");
success = false;
}
return success;
}
void Sprite::renderSprite()
{
SDL_Rect* curSprite = &spriteClips[frames];
sprite.renderImage((SCREEN_WIDTH - curSprite->w) / 2, (SCREEN_HEIGHT - curSprite->h) / 2, curSprite);
}
Graphics.cpp
#include "Graphics.h"
#include "Globals.h"
using namespace Globals;
Graphics::Graphics()
{
hei = 0;
wid = 0;
texture = NULL;
win = SDL_CreateWindow("Foo", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED,
SCREEN_WIDTH, SCREEN_HEIGHT, SDL_WINDOW_SHOWN);
ren = SDL_CreateRenderer(win, -1, SDL_RENDERER_ACCELERATED | SDL_RENDERER_PRESENTVSYNC);
if(win && ren == NULL)
{
printf("Failed to create Window & Renderer!\n");
}
else
{
int imgFlags = IMG_INIT_PNG;
if( !(IMG_Init(imgFlags) &imgFlags))
{
printf("Image flags not initiated!\n");
}
}
}
Graphics::~Graphics(){}
SDL_Texture* Graphics::loadImage(std::string file)
{
SDL_Texture* newTxtr = NULL;
image = IMG_Load(file.c_str());
if(image == NULL)
{
printf("Unable to load image\n");
}
else
{
newTxtr = SDL_CreateTextureFromSurface(ren, image);
if(newTxtr == NULL)
{
printf("Unable to create texture!\n");
}
else
{
wid = image->w;
hei = image->h;
}
SDL_FreeSurface(image);
}
texture = newTxtr;
return texture;
}
void Graphics::free()
{
if(texture != NULL)
{
texture = NULL;
wid = 0;
hei = 0;
}
}
void Graphics::renderImage(int x, int y, SDL_Rect* clip)
{
SDL_Rect dstClip = {x, y, wid, hei};
if(clip != NULL)
{
dstClip.w = clip->w;
dstClip.h = clip->h;
}
SDL_RenderCopy(ren, texture, clip, &dstClip);
}
void Graphics::render()
{
SDL_RenderPresent(ren);
SDL_UpdateWindowSurface(win);
}
void Graphics::clearScreen()
{
SDL_RenderClear(ren);
}
SDL_Renderer* Graphics::getRenderer()
{
return ren;
}
void Graphics::closeGraphics()
{
IMG_Quit();
SDL_DestroyRenderer(ren);
SDL_DestroyWindow(win);
}
GameLoop.cpp
#include "GameLoop.h"
#include "Graphics.h"
#include "Sprite.h"
GameLoop::GameLoop()
{
if(SDL_Init(SDL_INIT_EVERYTHING)< 0)
{
printf("Failed to init\n");
}
else
{
this->loop();
}
}
GameLoop::~GameLoop(){}
void GameLoop::loop()
{
Graphics graphics;
SDL_Event e;
bool quit = false;
while(!quit)
{
while(SDL_PollEvent(&e)!= 0)
{
if(e.type == SDL_QUIT)
{
quit = true;
}
}
this->renderGraphics(graphics);
}
this->close(graphics);
}
void GameLoop::loadSprite()
{
Sprite sp;
sp.renderSprite();
}
void GameLoop::renderGraphics(Graphics& graphics)
{
SDL_SetRenderDrawColor(graphics.ren, 0x00, 0x00, 0x00, 0x00);
graphics.clearScreen();
graphics.render();
}
void GameLoop::close(Graphics& graphics)
{
SDL_Quit();
graphics.closeGraphics();
}
I've included all but one of the .cpp files.
Thanks.
