The GameDev.net FreeBook is relevant to game designers, developers, and those interested in learning more about the challenges in game development. We know game development can be a tough discipline and business, so we picked several chapters from CRC Press titles that we thought would be of interest to you, the GameDev.net audience, in your journey to design, develop, and market your next game. The free ebook is available through CRC Press by clicking here. The Curated Books The Art of Game Design: A Book of Lenses, Second Edition, by Jesse Schell Presents 100+ sets of questions, or different lenses, for viewing a game’s design, encompassing diverse fields such as psychology, architecture, music, film, software engineering, theme park design, mathematics, anthropology, and more. Written by one of the world's top game designers, this book describes the deepest and most fundamental principles of game design, demonstrating how tactics used in board, card, and athletic games also work in video games. It provides practical instruction on creating world-class games that will be played again and again. View it here. A Practical Guide to Indie Game Marketing, by Joel Dreskin Marketing is an essential but too frequently overlooked or minimized component of the release plan for indie games. A Practical Guide to Indie Game Marketing provides you with the tools needed to build visibility and sell your indie games.

Beginning to code in C++, some rookie questions.

4 posts in this topic

Good evening, I am designing an RPG and attempting to teach myself all the relevant skills involved in producing the game. 

 

Before you all laugh, I am not attempting to complete the game as a one man army, I just want to learn a decent amount of art and design so that when I hire an artist, I can more accurately describe what I want in some of their own language. 

 

And so that when I hire a programmer, I can more accurately describe what I want in some of their own language. Besides, the more I learn, the more it all affects my concept (as in, what is realistic, what is workable, what is standard, and so on). Basically I want to be the best team leader I can by having at least some knowledge of all the relevant areas.

 

Also I just love learning stuff. 

 

 

Anyway, this is the code I have so far, using Visual C++ 2010 with SDL.

 

#pragma comment(lib, "SDL.lib")
#pragma comment(lib, "SDLmain.lib")
#pragma comment(lib, "SDL_TTF.lib")

#include "SDL.h"
#include "SDL_image.h"
#include <iostream>
#include <stack>
#include <string>
#include "SDL_TTF.h"
#include "Defines.h"

using namespace std;

int main(int argc, char *argv[])


{
const int SCREEN_WIDTH = 644;
const int SCREEN_HEIGHT = 400;
const int SCREEN_BPP = 32;

SDL_Surface *logo = NULL;
SDL_Surface *border = NULL;
SDL_Surface *screen = NULL;

SDL_Init(SDL_INIT_EVERYTHING);

SDL_WM_SetCaption("Necromancer", NULL);


screen = SDL_SetVideoMode( SCREEN_WIDTH, SCREEN_HEIGHT, SCREEN_BPP, SDL_SWSURFACE);
border = IMG_Load("Graphics/Title/Border.png");
logo = IMG_Load("Graphics/Title/Logo.png");


SDL_BlitSurface(logo,NULL,screen,NULL);
SDL_BlitSurface(border,NULL,screen,NULL);

SDL_Flip(screen);
SDL_Delay( 5000 );
SDL_FreeSurface(logo);
SDL_FreeSurface(border);

SDL_Quit();
return 0;
}

 

 

I have copied most of this stuff from websites, so most of it I genuinely have no idea what it does. But after hours of furious tweaking, it creates a screen in the size I want and displays two images I want for 5 seconds. A pretty big win for someone fumbling along. 

 

My question is, where do I insert code to tell the program to 'fade in' the logo, then fade it out again (over a total period of 3 seconds), and what what would that code look like?

 

Then I would like it to fade in and fade in a second image over 5 seconds, what would that code look like?

 

Thank you for your time and putting up with my awkward starting point. 

 

 

Kind regards,

 

Dan

Thank you for your response. 

 

I should explain, when I said "Before you all laugh" I am sorry if it came across as insecure or aggressive, I was trying to be playful but I sometimes forget that tone is always lost on the internet. 

 

I am about to sleep now but will try this code out tomorrow evening. Thank you again!

I would personally recommend against using code that you find on the web if you have no idea what it does. When something goes wrong (and it often does in programming) you'll have no idea what might be the problem, where is it, or how to fix it. Work through tutorials, books and references, and find it what each lines means. At the very least, get a general idea.

 

I also second the suggestion to start with python.
