Graphics / Re: Some textures become white square when I'm in release mode.

« on: March 02, 2018, 09:17:40 am »

So what to do? I don't want to use third-party libraries. I have to make it static because I have to reach the texture like this: TextureManager::GetTexture(TEXTURENAMES_FONT);

And it only occurs when I'm in release mode. If it didn't occur on debug mode, doesn't it mean that it works well? I don't get it.

Edit:
When I try to use the texture somewhere else, it did show. :O It only shows as white square in this code:

#include "InteriorPlan.hpp"
#include "../../AssetManagers/TextureManager/TextureManager.hpp"

const int backPlan[MapPlan::LENGTH] = {
        0, 0, 0, ...(I cropped out these data for simplicity) 0, 0, 0
};

const int midPlan[MapPlan::LENGTH] = {
        0, 0, 0, ...(I cropped out these data for simplicity) 0, 0, 0
};

const int frontPlan[MapPlan::LENGTH] = {
        0, 0, 0, ...(I cropped out these data for simplicity) 0, 0, 0
};

InteriorPlan::InteriorPlan() {

}

void InteriorPlan::Initialize() {
        int i = 0;
        for (i = 0; i < LENGTH; i++) {
                backTiles[i].SetPosition(sf::Vector2<float>((Tile::GetWidth()*(i % LENGTH)), (Tile::GetHeight()*(i / LENGTH))));
                backTiles[i].SetTexture(*TextureManager::GetTexture(TextureManager::TEXTURENAMES_TILES_INTERIOR));
                backTiles[i].SetTextureStartPosition(sf::Vector2f(
                        Tile::GetWidth() * (backPlan[i] % TextureManager::GetTexture(TextureManager::TEXTURENAMES_TILES_INTERIOR)->getSize().x),
                        Tile::GetHeight() * ((backPlan[i] / TextureManager::GetTexture(TextureManager::TEXTURENAMES_TILES_INTERIOR)->getSize().y))));
        }

        for (i = 0; i < LENGTH; i++) {
                midTiles[i].SetPosition(sf::Vector2<float>((Tile::GetWidth()*(i % LENGTH)), (Tile::GetHeight()*(i / LENGTH))));
                midTiles[i].SetTexture(*TextureManager::GetTexture(TextureManager::TEXTURENAMES_TILES_INTERIOR));
                midTiles[i].SetTextureStartPosition(sf::Vector2f(
                        Tile::GetWidth() * (midPlan[i] % TextureManager::GetTexture(TextureManager::TEXTURENAMES_TILES_INTERIOR)->getSize().x),
                        Tile::GetHeight() * ((midPlan[i] / TextureManager::GetTexture(TextureManager::TEXTURENAMES_TILES_INTERIOR)->getSize().y))));
        }

        for (i = 0; i < LENGTH; i++) {
                frontTiles[i].SetPosition(sf::Vector2<float>((Tile::GetWidth()*(i % LENGTH)), (Tile::GetHeight()*(i / LENGTH))));
                frontTiles[i].SetTexture(*TextureManager::GetTexture(TextureManager::TEXTURENAMES_TILES_INTERIOR));
                frontTiles[i].SetTextureStartPosition(sf::Vector2f(
                        Tile::GetWidth() * (frontPlan[i] % TextureManager::GetTexture(TextureManager::TEXTURENAMES_TILES_INTERIOR)->getSize().x),
                        Tile::GetHeight() * ((frontPlan[i] / TextureManager::GetTexture(TextureManager::TEXTURENAMES_TILES_INTERIOR)->getSize().y))));
        }
}

        MapPlan::Draw();

Graphics / Some textures become white square when I'm in release mode.

« on: March 01, 2018, 11:37:14 pm »

Hi. I have a question again.  Recently, I tried to show tiles on the screen, and there were 2500x3 sprites on the screen. I tried to render them all and it got slow. I tried to render a portion of them according to their position but it didn't work either. It got slow again. I'm always re instantiating the Sprite in a function in draw calls, maybe because of it, but what to do? When I declare the sf::Sprite in class declaration, it gives error when I try to call Window->Draw(sf::Sprite); It's weird.

Whatever, my here is my question: It basically doesn't draw some of my texture on the screen, actually just one texture. You can see texture_interior.png on the code:

#include "TextureManager.hpp"
#include <iostream>

sf::Texture TextureManager::textures[TEXTURENAMES_TEXTURECOUNT];
std::string TextureManager::texturePaths[TEXTURENAMES_TEXTURECOUNT];

TextureManager::TextureManager() {
        texturePaths[TEXTURENAMES_ARROWS] = "Bitmaps/System/arrows.png";
        texturePaths[TEXTURENAMES_BUTTONS] = "Bitmaps/System/buttons.png";
        texturePaths[TEXTURENAMES_FADE] = "Bitmaps/System/fade.png";
        texturePaths[TEXTURENAMES_FONT] = "Bitmaps/System/game_font.png";
        texturePaths[TEXTURENAMES_ICON] = "Bitmaps/System/icon.png";
        texturePaths[TEXTURENAMES_LANGUAGES] = "Bitmaps/System/languages.png";
        texturePaths[TEXTURENAMES_SHINE] = "Bitmaps/System/shine.png";
        texturePaths[TEXTURENAMES_LOGO] = "Bitmaps/System/system_logo.png";
        texturePaths[TEXTURENAMES_WHITEBRUSH] = "Bitmaps/System/white_brush.png";
        texturePaths[TEXTURENAMES_CHARBODY] = "Bitmaps/Character/Base/tileset_character_body.png";
        texturePaths[TEXTURENAMES_CHARDRESS] = "Bitmaps/Character/Armor/tileset_character_dress.png";
        texturePaths[TEXTURENAMES_CHARTOKA] = "Bitmaps/Character/Accessory/tileset_character_toka.png";
        texturePaths[TEXTURENAMES_CHARHAIR] = "Bitmaps/Character/Helmet/tileset_character_hair.png";
        texturePaths[TEXTURENAMES_WEAPONKIZILCIKSOPASI] = "Bitmaps/Character/Weapon/weapon_kizilcik_sopasi.png";
        texturePaths[TEXTURENAMES_TILES_INTERIOR] = "Bitmaps/Environment/tiles_interior.png";
        texturePaths[TEXTURENAMES_TILES_FOREST] = "Bitmaps/Environment/tiles_forest.png";
        texturePaths[TEXTURENAMES_EMPTY] = "Bitmaps/System/empty.png";
}

bool TextureManager::Initialize() {
        if (!SetTextures()) {
                return false;
        } else {
                return true;
        }
}

bool TextureManager::SetTextures() {
        bool textureLoadedCorrectly = true;
        for (int i = 0; i < TEXTURENAMES_TEXTURECOUNT; i++) {
                if (!textures[i].loadFromFile(texturePaths[i])) {
                        textureLoadedCorrectly = false;
                        break;
                }
        }

        return textureLoadedCorrectly;
}

sf::Texture* TextureManager::GetTexture(const int textureName) {
        return &textures[textureName];
}
 

Thank you so much. I don't know what to present more, so please ask more if you didn't understand a thing. (I didn't understand too actually )

Audio / Access violation when trying to play music in the wrapper class.

« on: February 18, 2018, 01:24:45 pm »

Hello all. I'm wrapping sf::SoundBuffer and sf::Sound classes in a class named SoundObject. It is followed like this:

SoundObject.h

#ifndef SOUNDOBJECT_H
#define SOUNDOBJECT_H

#include <string>
#include <SFML/Audio.hpp>

class SoundObject {
public:
        SoundObject();
        bool Create(std::string filename);
        void Play();
private:
        sf::Sound soundInstance;
        sf::SoundBuffer soundBuffer;
};

#endif

 

SoundObject.cpp

#include "SoundObject.h"
#include <string>
#include "../GameProperties/GameProperties.h"

SoundObject::SoundObject() {

}

bool SoundObject::Create(std::string filename) {
        if (!soundBuffer.loadFromFile(filename)) {
                return false;
        }

        soundInstance.setBuffer(soundBuffer);

        return true;
}

void SoundObject::Play() {
        soundInstance.setVolume(GameProperties::GetSFXVolume());
        soundInstance.play();
}
 

And I'm calling these functions in a class like this:

if (!changeSound.Create("Sounds/System/sound_change.ogg")) {
                return false;
        }

        if (!selectSound.Create("Sounds/System/sound_select.ogg")) {
                return false;
        }
 

changeSound and selectSound is member of a class.

But it gives access violation error. When I try to play the sounds in the main function, it doesn't give error. I don't get it. Can you help me?

Thanks.

Yes I am lack of experience about C++. Thanks, I'll try. ^^

Yes but you said that I didn't create the sprite. If it has a default constructor, why the program didn't create it? I fixed the problem with this approach, but I don't know if this is an expensive thing to process for RAM.

void GUIElement::Draw(sf::RenderWindow& window) {
        sf::Sprite sprite;
        sprite.setTexture(texture);
        sprite.setColor(sf::Color(255, 255, 255));
        window.draw(sprite);
}

How to create the sprite? I deleted pointers and now they are pure types.

Hi, I recently faced an access violation error. I was wrapping the sf::Texture and sf::Sprite classes into a GameObject class. Here is the data structure:

This line:

Thank you so much. What should I do? I don't want to use new keyword because of memory leakage. Using of new keyword is mandatory?

Hi all. I'm new to the SFML and the forum and I had some issues today. First of all, I want to use classes with SFML and I made a framework for this. File Structure is like this:

>main.cpp
>Framework>Window>Window.h and Window.cpp

Framework and main.cpp are at the same level. Window class lies beneath the framework folder.

main.cpp:

#include "Framework\Window\Window.h"
#include <iostream>
#include <SFML/Graphics.hpp>

int main()
{
        Window window(640, 360, "Title", false);

        while (window.IsOpen()) {
                window.Clear();
                window.Draw();
        }

    return 0;
}

 

Window.h

#ifndef WINDOW_H
#define WINDOW_H

#include <string>
#include <SFML/Graphics.hpp>

class Window {
public:
        Window(int width, int height, std::string title, bool fullscreen);
        bool IsOpen();
        void Clear();
        void Draw();
private:
        sf::RenderWindow* window;
        int windowWidth;
        int windowHeight;
        std::string windowTitle;
        bool windowFullscreen;
};

#endif
 

Window.cpp

#include "Window.h"

Window::Window(int width, int height, std::string title, bool fullscreen) {
        windowWidth = width;
        windowHeight = height;
        windowTitle = title;
        windowFullscreen = fullscreen;

        window = &sf::RenderWindow(sf::VideoMode(windowWidth, windowHeight), windowTitle, sf::Style::Close | sf::Style::Titlebar);

        window->setFramerateLimit(60);
}

bool Window::IsOpen() {
        return window->isOpen();
}

void Window::Clear() {
        window->clear();
}

void Window::Draw() {
        window->display();
}
 

What is the problem. Does SFML supports object oriented programming? By the way, clear function gives access violation error in the code.

Thanks.
