Have you added the SDL.lib and SDLmain.lib to linked libraries? Do you have the SDL.dll in the same folder as the executable?

[sandmaster]

Yea, got all of them lionked, and the files in the folder where i run the program.

It worked before in the last tutorials to run, i really hate when it happens for no specific reason

Could you post your sprite class?

Where is your load function in the cpp file?

[sandmaster]

Thats the problem, it isnt there :S

[stayscrisp]

DoNotWant is right, you've missed a function out. it's declared but never defined.

[sandmaster]

BUT i do call load from gamestate... Ah! there we go, thanks, I checked it up and i use it in gamestate, but i got my own method to load images, and when i replaced load with that method, it worked thats what i get when i follow tutorials and use diffent names

Thanks!

[DoNotWant]

I do those kind of renaming mistakes all the time too. Probably should start following tutorials verbatim.

[dannydoomno1]

heya i got a small error that i probably have created myself because im an idiot but im getting this error when i run my code

C:\game\MenuState.cpp|13|undefined reference to `Sprite::Load(char*)'|

in this file

menustate.cpp

#include <stdio.h>

#include "SDL\SDL.h"
#include "Game.h"
#include "MenuState.h"
#include "sprite.h"

MenuState MenuState::m_MenuState;

void MenuState::Init()
{
	menuSprite = NULL; // set pointer to NULL;
	menuSprite = Sprite::Load("menustate.bmp"); // load menu state bitmap
	printf("MenuState Init Successful\n");

void MenuState::Clean()
{
	printf("MenuState Clean Successful\n");

}

void MenuState::Resume()
{
	printf("MenuState Resumed\n");
}

#include "PlayState.h"  // include PlayState.h

// now we will go into the MenuState::HandleEvents(Game* game)

void MenuState::Update(Game* game)

void MenuState::Draw(Game* game)
{
   Sprite::Draw(game->GetScreen(), menuSprite, 0, 0); // we will write
													  // GetScreen() in a second
   SDL_Flip(game->GetScreen());
}

iv been through all of your tutorial many times and tried to fix it a hundred times but im new to C / C++ iv only been using it just over a week so sorry if im being a noob

[stayscrisp]

Can you post more of your project please, looks like you have not defined your sprite load function.

[gamer27lv]

Hi I am using CodeBlocks to follow these tutorials. not really having any problems with the code but I would like to be able to see the printf text.. where does it output to? It doesn't show up in the build log... and when I put the build target as Release instead of Debug, a black consol type window shows up but nothing outputs there either.

Would appreciate if someone can point out where to see it! thank you

[stayscrisp]

Code blocks prints to the files stdout.txt/stderr.txt but you can redirect them using these lines:

freopen("CON", "w", stdout); // redirects stdout
freopen("CON", "w", stderr); // redirects stderr
