General / Question related to game in "SFML game development" book

« on: April 27, 2015, 07:16:35 pm »

I had some troubles in my game-architecture. The question was - how to make Enemy objects, Bullet objects and Player object interact one with another without implementing tons of singletones?
I decided to look up for decision of this problem in SFML development book. I read 7 chapters of this book, paid attention to every line of it, but i still can't find solution: how to make enemies objects know where player is located to move forward to it? Cuz i was a bit disappointed, when i realized that flights in that example game were moving just by patterns and made an illusion of AI.
Should i make methods like

void Enemy::move(Player& player, float dt);

? I mean, using references to other classes. Doesn't it ruin OO-style?
Or should I just use those singletones?
Sorry for such questions, but game-architecture brings lots of troubles for people without experience in it

General / [SOLVED]How to hold the game map in tile-based 2d game?

« on: November 15, 2014, 02:02:19 pm »

For example, i have 180x40 map, each tile is 32x32 pixels.
Is it efficiently to hold em in the two-dimensional matrix? Is this bad way? I am new to gamedev, so i have some troubles with this question.
Another idea is to hold game objects in vector of pointers, is this better one?
Thanks for answers.

General / The program exiting with code -1073741515

« on: September 30, 2014, 06:42:06 pm »

I have the trouble. My OS is windows7 x64, trying to get my SFML WD (for gcc 4.7.0) working
But it doesn't. Simple code

#include <iostream>
#include <conio.h>
#include <SFML/Graphics.hpp>
using namespace std;

int main()
{

 sf::RenderWindow App(sf::VideoMode(800, 600, 32), "Hello World - SFML");
    return 0;
}
 

And

Project1\build-untitled-Desktop_Qt_5_3_MinGW_32bit-Debug\debug\untitled.exe exited with code -1073741515

What's wrong? Can show my .pro file too.

TEMPLATE = app
CONFIG -= app_bundle
CONFIG -= qt

SOURCES += main.cpp

include(deployment.pri)
qtcAddDeployment()

#SFML library
LIBS += -LD:\QTcreator\Tools\SFML-2.1\lib
 
CONFIG(release, debug|release): LIBS += -lsfml-audio -lsfml-graphics -lsfml-main -lsfml-network -lsfml-window -lsfml-system -DSFML_STATIC
CONFIG(debug, debug|release): LIBS += -lsfml-audio-d -lsfml-graphics-d -lsfml-main-d -lsfml-network-d -lsfml-window-d -lsfml-system-d -DSFML_STATIC
 
INCLUDEPATH += D:\QTcreator\Tools\SFML-2.1\include
DEPENDPATH += D:\QTcreator\Tools\SFML-2.1\include

Can anyone help me?
