I am using Codeblocks 10.05 and i have recently been making a pong clone game using sdl, this is my first major project in C++ and using SDL. I have finished my writing code and have successfully compiled it with no errors, while writing my code i ran the compile and ran the program at different stages with no problems but now that i have finished coding i can compile the code but when it runs there is no output on the screen.
the code below is my main.cpp file.
#include <SDL/SDL.h>
002 #include <SDL/SDL_ttf.h>
003 #include <iostream>
004 #include "ball.h"
005 #include "Paddle.h"
006 //#include "110ct.h"
007
008 SDL_Surface* load_image(const char* c, Uint32 colorkey=0)
009 {
010 SDL_Surface* tmp=SDL_LoadBMP(c);
011 if(colorkey!=0)
012 {
013 SDL_SetColorKey(tmp, SDL_SRCCOLORKEY, colorkey);
014 }
015 return tmp;
016 }
017
018 int main()
019 {
020 SDL_Surface*screen;
021 SDL_WM_SetCaption("110CT PONG", NULL);
022 TTF_Font* font;
023 TTF_Init();
024 font=TTF_OpenFont("handsean.ttf",20);
025 SDL_Color color = {0,0,0};
026 const int FPS = 30 ;

036 ball ball1(load_image("ball.bmp", SDL_MapRGB(screen->format, 0x44,0xf1,0x40)),320,240,20,20,3,3);

120 ball1.display();
121
122 char c[5];
123 SDL_Rect tmp = {10,0};
124 sprintf(c,"%d",player1.getScore());
125 SDL_Surface* text=TTF_RenderText_Solid(font,c,color);
126 SDL_BlitSurface(text,NULL,screen,&tmp);
127
128
129 tmp.x=width-40;
130 sprintf(c,"%d",player2.getScore());
131 text=TTF_RenderText_Solid(font,c,color);
132 SDL_BlitSurface(text,NULL,screen,&tmp);
133 SDL_FreeSurface(text);
134
135 SDL_Flip(screen);
136
137 //regulate FPS
138 if (1000/FPS>(SDL_GetTicks()-start))
139 SDL_Delay(1000/FPS-(SDL_GetTicks()-start));
140
141 }
142
143 TTF_CloseFont(font);
144 TTF_Quit();
145 SDL_Quit();
146
147 }
after compiling the command line reads :
Checking for existence: C:\Users\Sylvester\Desktop\110CT PROJECT (PONG)\PONG.exe
Executing: "C:\Users\Sylvester\Desktop\110CT PROJECT (PONG)\PONG.exe" (in C:\Users\Sylvester\Desktop\110CT PROJECT (PONG)\.)
Process terminated with status 0 (0 minutes, 0 seconds)
has anyone got experience with this problem and can possibly help me
thanks.
