Graphics / SFML Button

« on: November 13, 2013, 07:54:40 am »

Hi, I made a small Button set since SFML doesnt have a button class directly inputted into it, so I tried to make my own, and I got this, you can add/change/modify it to your liking

//Get the position of the Mouse
int MouseX = sf::Mouse::getPosition().x;
int MouseY = sf::Mouse::getPosition().y;

//Create a Shape for the button
sf::RectangleShape button; //Doesnt have to be a rectangle

//Give the Button a color
button.setFillColor(sf::Color::Blue);

//Set size of the button
button.setSize(sf::Vector2f(100,48)); //Make it what ever you like

//Set the position of the button
button.setPosition(200,200);//or where ever you like

//The Fun Stuff!!
if(button.getGlobalBounds().width <=> MouseX
&& button.getGlobalBounds().height <=> MouseY){
//Do What you want to do with the button
button.setFillColor(sf::Color::Green);
}

 

Now this may not be the most efficient way to do this, but it worked for me when I tried it.

Graphics / Re: Handleing First Chance Error when loading images

I know how to use them a bit. But I have put it there because I get the following error once I debug without the pointer.

d:\game\lengine.cpp(55): error C2664: 'sf::Shape::setTexture' : cannot convert parameter 1 from 'sf::Texture' to 'const sf::Texture *'
          No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called

Graphics / Handleing First Chance Error when loading images

« on: November 02, 2013, 08:11:42 am »

Hi, whenever I run my application, and I want to set rect image to the grass. It keeps on giving me a first chance exception. Here is the 2 stacktraces

First-chance exception at 0x1004ab8d in Game.exe: 0xC0000005: Access violation writing location 0x00000000.
Unhandled exception at 0x1004ab8d in Game.exe: 0xC0000005: Access violation writing location 0x00000000.

I'm a little confused, could anybody tell me what is going on? I have added the code that is drawing and setting the rect on the screen below.

sf::RectangleShape rect;

sf::Texture* grass;
grass->loadFromFile("grass.png");

rect.setSize(sf::Vector2f(16,16));
rect.setTexture(grass);
rect.setPosition(x * 16, y * 16);
window.draw(rect);

window.setView(map_view);
window.display();

I have sf::RenderWindow* window; in the header file.

That's what I mean: Just use

sf::RenderWindow window;

Or do you want to reduce compile-time dependencies (Pimpl idiom)?

What do you mean by "reduce compile-time dependencies"?

I have sf::RenderWindow* window; in the header file.

It also stops the startup at : 'Game.exe': Loaded 'C:\WINDOWS\system32\imagehlp.dll', Cannot find or open the PDB file

Also what does

Unhandled exception at 0x103159da (msvcr100d.dll) in Game.exe: 0xC0000005: Access violation reading location 0xccccccc0.

General / Converting a sf::Image to a sf::Texture

« on: October 01, 2013, 12:36:53 pm »

Hi, I need to convert a image to a texture for my application, but I cannot find anywhere that tells you how to do so.

Could anybody link me to a post or a post some code or a way they would do it ?

Cheers TheDianamu

Graphics / setImage not a member of sf::Sprite

« on: September 29, 2013, 04:10:54 am »

I'm having troubles with my tile class for my engine. I'm using the SFML 2.1 and coding visual c++ 2010

I get the following on compile:

'setImage' : is not a member of 'sf::Sprite'

Tile.cpp:

#include "Tile.h"
#include <SFML\Graphics.hpp>

Tile::Tile(sf::Image& image)
{
        baseSprite.setImage(image, true);
}

Tile::~Tile()
{

}

void Tile::Draw(int x, int y, sf::RenderWindow* rw)
{
        baseSprite.setPosition(x, y);
        rw->draw(baseSprite);
}

Tile.h:

#ifndef _TILE_H
#define _TILE_H

#include <SFML\Graphics.hpp>

class Tile
{
private:
        sf::Sprite baseSprite;

public:
        Tile(sf::Image& image);
        ~Tile();

        void Draw(int x, int y, sf::RenderWindow* rw);
};

Graphics / How to fill the window with a texture/sprite

« on: September 20, 2013, 03:42:42 pm »

I'm trying to figure out a quick and simple way of filling the entire window or to a size say like

width of 200 sprites
height of 200 sprites

How would I go about setting the texture/sprite to fill that size? I have tried to use setRepeated, but that wasn't working.

Thanks in Advance
