Another c++ error

Tyler · 2011-10-21T00:47:47

Im sorry to post about another error, I am new to c++. My errors this time are Error 1 error C2143: syntax error : missing ';' before '*' Error 2 error C4430: missing type specifier - int assumed. Error 3 error C2065: 'TOTAL_TILES' : undeclared identifier Error 4 error C4430: missing type specifier - int assumed. Note: C++ does not support default-int I do have literally 294 errors but I figure its only about 20-30 errors causing all of the other errors. anyway here is the code. note that I moved extern Tile *tiles[TOTAL_TILES]; because it seemed more suited there. main.cpp #include "SDL.h" #include "basic_functions.h" #include "graphic_functions.h" #include "tile_load.h" #include "graphics.h" #include "class_player.h" #include "class_tile.h" #include "collision.h" // main surfaces // the screen surface SDL_Surface* surface_screen; // the surface for the player ///////////////varibles/////////////////////// // // if this is off then the game quits // bool running = true; // // // the width and height of the level // // will need to be changed so that // // the world is one continuios map // const int level_width = 1000; // const int level_height = 1000; // // // the screens dimensions // const int screen_width = 960; // const int screen_height = 960; // const int screen_bbp = 32; // // // the frames per second regulator // const int frames_per_Second = 20; // //////////////varibles end//////////////////// // the camera SDL_Rect camera = {0, 0, screen_width, screen_height}; // the tile varible Tile *tiles[TOTAL_TILES]; // events SDL_Event event; int main(int argc, char* argv[]) { SDL_Init(SDL_INIT_EVERYTHING); surface_screen = SDL_SetVideoMode(screen_width, screen_height, 32, SDL_SWSURFACE); load_tile_var(); //laods the dotclass player mainplayer; // load maps and map things clip_tiles(); while(running == true) { // main loop //if sdl finds an event if(SDL_PollEvent(&event)) { x_quit(); // checks if player has moved // if player has moved then it moves the sprite // at the draw sprite function mainplayer.handle_input(); } //loads the graphics load_graphics(); // draws the background so that the sprites can erase properly spr_background(); //loads the test map // place holder [load_map("maps\\map.map");] mainplayer.move(tiles); //show tiles for(int t = 0; t < TOTAL_TILES; t++){ tiles[t]->show(); } // game start // draws the players surface mainplayer.show(); // flips the screen and draws all new graphics SDL_Flip(surface_screen); } SDL_Quit(); return 0; } and main.h #pragma once #include "SDL.h" #include "tile_load.h" //varibles extern bool running; extern const int level_width; extern const int level_height; extern const int screen_width; extern const int screen_height; extern const int screen_bbp; extern Tile *tiles[TOTAL_TILES]; // camera extern SDL_Rect camera; //events extern SDL_Event event; // surfaces extern SDL_Surface* surface_screen; And you may think that I haven't even looked up my errors, but i spent 2 hours last night googling my errors. if anymore information or files is required please ask. thanks for your time.

Well, one problem is with your class_player.h file

#ifndef CLASS_PLAYER_H

#define CLAS_PLAYER_H

You need to run it in the debugger to see where this happens and go from there.

The compiler keeps bringing up crtexe.c it's not even part of my project.

Ive looked around and i think it may be a null pointer but Im not sure what that is.

It is a null pointer. The null pointer is typically 0x00000000, small offsets from this are not uncommon when accessing a member of a structure.

The location of the crash can (and often will) be removed from the place that is causing the crash to occur - the place that takes a null pointer an d passes it to some function.

Have you investigated the call stack in the debugger? You should be able to use this to trace back to one of your functions that is calling into the C runtime (explicitly, or implicitly through SDL or the C++ runtime, for example). You can then inspect the variables in the debugger, looking for ones that are null or close to null.

Ok well i found the memory window and found the address and all that came up where a bunch of question marks. Does this mean anything.

You need to be compiling in debug mode to use the debugger.
