I was watching this series = https://www.youtube.com/watch?v=2NVgHrOFneg and for some reason for the guy in the video the code works but for me it compiles fine but doesn't load an image. I really don't know what to do
#include "SDL.h"
#include <iostream>
#include "SDL_image.h"
SDL_Texture *LoadTexture(std::string filePath, SDL_Renderer *renderTarget)
{
SDL_Texture *texture = nullptr;
SDL_Surface *surface = IMG_Load(filePath.c_str());
if (surface == NULL)
std::cout << "Error 1" << std::endl;
else
{
texture = SDL_CreateTextureFromSurface(renderTarget, surface);
if (texture == NULL)
std::cout << "Error 2" << std::endl;
}
SDL_FreeSurface(surface);
return texture;
}
int main(int, char *argv[])
{
const int FPS = 144;
int frameTime = 0;
SDL_Window *window = nullptr;
SDL_Texture *currentImage= nullptr;
SDL_Renderer *renderTarget = nullptr;
SDL_Rect playerRect;
int frameWidth, frameHeight;
int textureWidth, textureHeight;
SDL_Init(SDL_INIT_VIDEO );
int imgFlags = IMG_INIT_PNG | IMG_INIT_JPG;
if (!(IMG_Init(imgFlags) != imgFlags))
{
printf("IMG_Init: Failed to init required jpg and png support!\n");
printf("IMG_Init: %s\n", IMG_GetError());
}
window = SDL_CreateWindow("SDL Pong", SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED, 1024, 720, SDL_WINDOW_SHOWN);
renderTarget = SDL_CreateRenderer(window, -1, SDL_RENDERER_ACCELERATED | SDL_RENDERER_PRESENTVSYNC);
currentImage = LoadTexture("image.png", renderTarget);
//
//currentImage = SDL_LoadBMP("")
SDL_QueryTexture(currentImage, NULL, NULL, &textureWidth, &textureHeight);
//currentImage = IMG_LoadTexture(nullptr,"image.png" );
SDL_SetRenderDrawColor(renderTarget, 0xFF, 0, 0, 0xFF);
frameWidth = textureWidth / 3;
frameHeight = textureHeight / 4;
playerRect.x = playerRect.y = 0;
playerRect.y = frameWidth;
playerRect.h = frameHeight;
//SDL_SetRenderDrawColor(renderTarget, 0xFF, 0, 0, 0xFF);
bool isRunning = true;
SDL_Event ev;
while (isRunning)
{
while (SDL_PollEvent(&ev) != 0)
{
if (ev.type == SDL_QUIT)

}

if (FPS / frameTime == 4)
{

if (playerRect.x >= textureWidth)
playerRect.x =0;
}
SDL_RenderClear(renderTarget);

}
SDL_DestroyWindow(window);

SDL_DestroyRenderer(renderTarget);
window = nullptr;
renderTarget = nullptr;
currentImage = nullptr;
SDL_Quit();
return 0;
}
