General / [SOLVED] sf::Event help

« on: January 10, 2018, 02:48:23 am »

I'm following the SFML Game Develoment by Example and I'm having a problem with the EventManager class. I know that the sf::Event have changed in the past versions of SFML. Can anyone help me out with this crazy error?

*Note I'm using SFML 2.4.2*

General / Help with Game Loop

« on: October 06, 2016, 05:27:02 pm »

So I was working on game states a few weeks ago and I couldn't get the game states to transition. after look at the code and walking threw it, I never render I'm stuck within my loop and I don't remember what I changed.

Can anyone see what is wrong with this game loop? I'm stuck in the nested while loop.

        sf::Clock clock;
        _deltaTime = clock.getElapsedTime();
        while (_window->isOpen())
        {
                _deltaTime += clock.restart();
                while (_deltaTime.asSeconds() >= _frameTime)
                {
                        if (currentState() == nullptr) continue;
                        currentState()->handleInput();
                        currentState()->update(_deltaTime);
                        _deltaTime += clock.restart();

Graphics / [SOLVED]Can't load PNG Textures?

« on: August 13, 2016, 07:34:49 am »

trying to load a somewhat big texture file:
http://opengameart.org/content/isometric-hero-and-heroine

I'm getting an error that says this:

PNG not supported: 1/2/4/8-bit only

Never had this error before maybe someone can fill me in on what is going on.

FIX:
*Apparently I just had to compress the textures.*

General / SetImage() no longer work?

« on: August 02, 2016, 06:16:42 pm »

I was following this tutorial: https://github.com/SFML/SFML/wiki/Tutorial:-Image-Manager
 
and when I got to this point:

test_sprite[i].SetImage( img_mgr.get_image( "test.png" ) );

Can you no longer use SetImage()? I'm using SFML 2.3.2
Can anyone Help? and would you suggest turning this ImageManager into a TextureManager?

I'm getting back into C++ before I forget it all.. I'm vary rusty. I'm following all the SFML books and tutorials.

The question I have is Why is my _Player movement is radical?
Is this because of the _Window.setFramerateLimit(FPS) ?

General / Tutorial switch help?[SOLVED]

« on: August 10, 2015, 02:01:15 pm »

I'm sure this is a no brainer for some..

I'm getting a syntax error with: case sf::Event::KeyPressed: 'A';
Error says: case label value has already appeared in the switch

Is there a way to change the switch around to have multiple cases?
Thanks in advance!

CODE:

(click to show/hide)

while (window.pollEvent(event))
                {
                        //Event List
                        switch (event.type)
                        {
                                // window closed
                        case sf::Event::Closed:
                                window.close();
                                break;

                                // key pressed
                        case sf::Event::KeyPressed: 'W';

General / window.clear()?[SOLVED]

« on: August 06, 2015, 03:59:48 pm »

What I'm using: VS2013, SFML2.3

I'm learning the basics off of the website. and for some reason window.clear() method does not exists?
Is this because the tutorial is out of date?

CODE:

(click to show/hide)

Code: [Select]

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

int main()
{
sf::Window window(sf::VideoMode(800, 600), "Your my Daddy!");
std::cout << "Window Created" << std::endl;
// run the program as long as the window is open
std::cout << "Waiting for events..." << std::endl;
while (window.isOpen())
{
// check all the window's events that were triggered since the last iteration of the loop
sf::Event event;

while (window.pollEvent(event))
{
//Event List
switch (event.type)
{
// window closed
case sf::Event::Closed:
window.close();
break;

// key pressed
case sf::Event::KeyPressed: 'W';
std::cout << "Key: W Pressed." << std::endl;
break;

// we don't process other types of events
default:
break;
}
}


// draw everything here...
// window.draw(...);
window.clear();
sf::RectangleShape rectangle(sf::Vector2f(50, 50));
// end the current frame
window.display();

I'm trying to move mPlayer to Mouse Position when Clicked witch I have done..
but Now I'm trying to make the mPlayer move at a set speed over time.

How would do this with time? I can find my distance (MouseX - PlayerX) (MouseY - PlayerY) and set speed?
