      Download the Game Design and Indie Game Marketing Freebook   07/19/17

      GameDev.net and CRC Press have teamed up to bring a free ebook of content curated from top titles published by CRC Press. The freebook, Practices of Game Design & Indie Game Marketing, includes chapters from The Art of Game Design: A Book of Lenses, A Practical Guide to Indie Game Marketing, and An Architectural Approach to Level Design. 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. With special focus on those developers with small budgets and limited staff and resources, this book is packed with tangible recommendations and techniques that you can put to use immediately. As a seasoned professional of the indie game arena, author Joel Dreskin gives you insight into practical, real-world experiences of marketing numerous successful games and also provides stories of the failures. View it here. An Architectural Approach to Level Design This is one of the first books to integrate architectural and spatial design theory with the field of level design. The book presents architectural techniques and theories for level designers to use in their own work. It connects architecture and level design in different ways that address the practical elements of how designers construct space and the experiential elements of how and why humans interact with this space. Throughout the text, readers learn skills for spatial layout, evoking emotion through gamespaces, and creating better levels through architectural theory. View it here.

error Run-Time Check Failure #0

Hello guys, i have problem with my code


tankGame.h

[CODE]
class myTank;
class TankSteering;
//enum KEYS{ W, S, A, D,J,K};
class TankGame{
public:
TankGame(ALLEGRO_DISPLAY* display);
~TankGame();
myTank* m_player;
TankSteering* m_TankSteering;
void Update();
void Render();
};
[/CODE]


myTank.h

[code]
class TankGame;
class TankSteering;

class myTank : public MovingEntity {
public:
myTank(TankGame* tank_game, Vector2D pos, ALLEGRO_DISPLAY* display);
~myTank();
void Update();
void Render();
....blah....
private:
....blah....
TankSteering* m_pSteering;
TankGame* m_tankGame;

};

[/code]

tankSteering.h
[code]
class myTank;
class TankGame;
class TankSteering
{
public:
TankSteering(myTank* player, TankGame* tankGame);
//TankSteering();
~TankSteering();
Vector2D Calculate();
Vector2D Player_Steering();
private:
TankGame* m_pTankGame;
float m_fMaxForce;
myTank* m_tplayer;
float m_fDesRateForce;
};
[/code]

TankGame.cpp
[code]

TankGame::TankGame(ALLEGRO_DISPLAY* display)
{
m_player = new myTank(this, Vector2D(200.0f, 200.0f), display);
//m_TankSteering = new TankSteering(this);
for(int i = 0; i < 6; i++)
{
keys[i] = false;
}
}
blah blah
[/code]

the thing is, when i remove the line "m_player = new myTank(this, Vector2D(200.0f, 200.0f), display);" in my tankGame, it work. But when i add this line in TankGame constructor, error "error Run-Time Check Failure #0" happened. when i create an object of myTank in mainfunction, it worked. Someone can help me [img]http://public.gamedev.net//public/style_emoticons/default/smile.png[/img]. Thank in advance Edited by linhmai27

I don't know allergro, but what about the 'script' var in the constructor of myTank ? It seems to be a global var, is it already initialized when accessing it in the constructor ? Edited by Ashaman73

thank for reading my topic. When i create object of myTank in main function, and render it. All things work.

but when i create object of TankGame in main function( it include instance of mytTank, it call constructor of m_player, and in debug mode, it goes to the end of TankGame constructor ( in this case, it created myTank object ),it raise "error Run-Time Check Failure #0" here

script is an singleton class, and i tested it, it worked. [img]http://public.gamedev.net//public/style_emoticons/default/smile.png[/img]

[CODE]
#ifndef TANK_SCRIPTOR
#define TANK_SCRIPTOR
#pragma warning (disable:4786)
//-----------------------------------------------------------------------------
//
// Name: Raven_Scriptor
//
// Author: Mat Buckland (www.ai-junkie.com)
//
// Desc: A Singleton Scriptor class for use with the Raven project
//-----------------------------------------------------------------------------
#include <script\Scriptor.h>
#define script Tank_Scriptor::Instance()
class Tank_Scriptor : public Scriptor
{
private:

Tank_Scriptor();
//copy ctor and assignment should be private
Tank_Scriptor(const Tank_Scriptor&);
Tank_Scriptor& operator=(const Tank_Scriptor&);
public:
static Tank_Scriptor* Instance();
};

#endif
