General / Is there any way to use shaders on opengl es 1.4?

« on: October 15, 2017, 12:06:13 am »

I don't want to remake my game in directx, so, i want to know if there's any hope to get shaders working on the opengl es version i currently have.

I found what's happening!

Code: [Select]

int8_t i;

for (const auto& x : objects)
{
objects[i].update();
objects[i].draw(m_window);
i++;
}

i = 0;

I declared a signed int8_t variable, which explains why the object limit was being 127!!!
So, i changed it to a unsigned short, and now i can have 65535 objects in screen.

Thanks for the help guys!

I ran the debugger, and after the crash, this appear in the debugger

Code: [Select]

Program received signal SIGSEGV, Segmentation fault.
At Core.cpp:73

Core.cpp:73 is the  objects.update();

Do you mean that's happening stack overflow?
Then, how i can fix it? Because the game crashes after the first object when i do this:

Code: [Select]

std::vector<GameObject*> objects;

if (sf::Keyboard::isKeyPressed(sf::Keyboard::B))
{
    GameObject* obj = new GameObject(sortOfATex);
    objects.push_back(obj);
    delete obj;
}

int8_t i;

for (const auto& x : objects)
{
objects[i]->update();
objects[i]->draw(m_window);
i++;
}

i = 0;

My game crashes after my objects vector's size gets higher than 127.

This is my code

--- Main loop function

Code: [Select]

// Set the FPS limit of the window
m_window.setFramerateLimit(60);

// Activate the window
m_window.setActive(true);

// Disable lighting
glDisable(GL_LIGHTING);

// Configure the viewport (the same size as the window)
glViewport(0, 0, m_window.getSize().x, m_window.getSize().y);

// Enable OpenGL
glEnable(GL_TEXTURE_2D);

// Load all scenes
SceneTest sc_0;
scenes.push_back(&sc_0);

sf::Texture sortOfATex;
sortOfATex.loadFromFile("data/uglie.gif");

// Main game loop
while (m_window.isOpen())
{
// Event
sf::Event event;

while (m_window.pollEvent(event))
{
// Close the game when the [X] button is clicked
if (event.type == sf::Event::Closed)
m_window.close();
}

// Clear the buffers
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

// Run the scene
scenes[currentScene]->run(m_window);

if (sf::Keyboard::isKeyPressed(sf::Keyboard::B))
{
GameObject obj(sortOfATex);
objects.push_back(obj);
}

int8_t i;

for (const auto& x : objects)
{
objects[i].update();
objects[i].draw(m_window);
i++;
}

i = 0;

// Display the things on the window
m_window.display();

}
--- GameObject
Source file

Code: [Select]

#include "GameObject.hpp"

GameObject::GameObject(sf::Texture& text)
    : spr(text)
{}

GameObject::~GameObject() {}

void GameObject::update()
{
    spr.move(1, 0);
}

void GameObject::draw(sf::RenderWindow& w)
{
    w.draw(this->spr);
}
