Window / Recommended way to change mouse cursor

« on: March 31, 2020, 04:18:00 pm »

Hello,

This is just a quick question about changing the mouse cursor image for different events, "Move, Click, etc".
What is the recommended way to do this ?
1) Create new sf::Cursors for each event ?
2) Use a sprite ?
3) Is there a way I am missing ?

Regards.

General / CPU usage 100% help

« on: June 03, 2017, 05:24:02 pm »

Quick question
Why is my cpu usage at 100% when I enable vsync ?
If I used window.setFramerateLimit(60) this is not the case and the cpu usage is relatively low

My graphics card is a nvidia gtx970.
Thanks

Code: [Select]

int main()
{
sf::RenderWindow window(sf::VideoMode(200, 200), "SFML works!");
window.setVerticalSyncEnabled(true);

while (window.isOpen())
{
sf::Event event;
while (window.pollEvent(event)){
if (event.type == sf::Event::Closed)
window.close();
}
window.clear();
window.display();
}
return 0;
}

Just wondering what is the correct way to handle input across many classes. Example title scene, game scene.

Thanks

General / Setting up shader problems

« on: October 29, 2016, 11:45:20 pm »

Just looking over the asset SFML manager on Git and wondering the following.

// Loads Shader into a map
m_shaders.load(Shaders::Shockwave, "../resources/shader/shockwave.vert", "../resources/shader/shockwave.frag");

// x = shader in the map
sf::Shader &x = m_shaders.get(Shaders::Shockwave);

If I had a shader created in my .h file how do I go about adding the shader stored in my map to the shader I created ?

Or is it better to ignore an assest manager for shaders and just loadFromFile ?

General / Screen wrap with views

« on: October 29, 2016, 12:42:13 pm »

I am looking for advice to approach this problem.

The game will be 4 screens across.
The view will be 1 screen in size.
My player will always be in the centre of the screen.
When the player centre x point > 4th screen centre you should see the 1st screen again.

Thanks in advance

General / Quick Question about objects and tiles

« on: October 04, 2016, 08:26:52 pm »

Is it better to have a tile ref/point to an object or use and ID and loop through the vector of objects and decide which object were talking about ?

Also what if we have multiple objects on the same tile ?

General / Just a quick query is all.

« on: September 24, 2016, 01:28:25 pm »

I was just wondering about general things from the code below is anyone can help.

#1 Does calling process"Polling Events" matter that its only updated 60 times a second ?
#2 Is it a waste to render as fast as possible ?

Thanks

// This code is from https://github.com/SFML/SFML-Game-Development-Book

void Game::run()
{
        sf::Clock clock;
        sf::Time timeSinceLastUpdate = sf::Time::Zero;
        while (mWindow.isOpen())
        {
                sf::Time elapsedTime = clock.restart();
                timeSinceLastUpdate += elapsedTime;
                while (timeSinceLastUpdate > TimePerFrame)
                {
                        timeSinceLastUpdate -= TimePerFrame;

                        processEvents();
                        update(TimePerFrame);
                }

                updateStatistics(elapsedTime);
                render();
        }
}

Graphics / Loking for a better solution for swapping pixel colors

« on: April 10, 2016, 10:51:37 pm »

Basically what I am at, is trying to change certain colors of a sprite to other colors. "Palette Swap kind of"

I can do it by changing the images pixels and tex.update(image), sprite.setTex(tex)
Is there an easier option to do this ?

Would using opengl help and can I still use sprite instead of a quad ?

Thanks in advance.
