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 / 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();

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);
};

#endif

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

General / How to draw randomly for a game

« on: September 17, 2013, 10:15:46 am »

Hi, as you have read by a lot of people. I'm working on a game. I'm just thinking how to pre-load a map for my game, so that I have say 600x600 pixels, the map is drawn with a texture 600x600 pixels with a texture of 16, I know how to get the texture made, just don't know how to draw more textures onto the screen.

I was thinking of maybe if SFML has the ability do window.draw(sprite,x,y); where x and y are the positions of the texture/tile. But that would take too long, so I was wondering if there is a easy way to do it.

Regards TheDianamu

Thanks in advance

Graphics / sf::Keyboard Only move the Sprite in the direction once

« on: September 15, 2013, 08:09:49 am »

Hi, I'm working on a game and I'm stuck on Movement

I have the following code in my main.cpp

                if(sf::Keyboard::isKeyPressed(sf::Keyboard::Left)) sprite.move(-20,0);
                if(sf::Keyboard::isKeyPressed(sf::Keyboard::Right)) sprite.move(20,0);
                if(sf::Keyboard::isKeyPressed(sf::Keyboard::Up)) sprite.move(0,-20);
                if(sf::Keyboard::isKeyPressed(sf::Keyboard::Down)) sprite.move(0,20);
 

Im just trying to figure out, why it isn't allowing me to move the sprite continually. Would I need to do something like

float speed = 5.f;

?

Thanks in advance.
