Graphics / Re: Tilebased map

« on: October 14, 2013, 10:13:01 pm »

I saw a tutorial of enums but I don't understand this:

        enum Terrain
        {
             water,
             lava,
             grass,
        };

I did this but now I don't understand how to assign i.e a water texture to Terrain::water.
I couldnt find a good tutorial on enums and I really don't know what to do
Can someone explain me enums and then I'll try to make tiles.If I fail I'll ask someone for help.

I'll try to find that tutorial with vertex array.
I'll see what a rendertexture is.
I assigned water the same way I did with grass and lava.
I'll see what an enum is.
I made a rectangle,movement and added collision like this:

rect.move(xVelocity, 0);

for(int i=0; i < 56;i++)
{
       if(rect.getGlobalBounds().intersects(waterCollision[i].getGlobalBounds())) rect.move(-xVelocity, 0);
}

rect.move(0, yVelocity);

for(int i=0; i < 56;i++)
{
       if(rect.getGlobalBounds().intersects(waterCollision[i].getGlobalBounds())) rect.move(0, -yVelocity);
}

Graphics / Tilebased map

« on: October 13, 2013, 01:43:18 pm »

I'm trying to make a tilebased map.
I made a texture for water,grass,lava.
Then I made a rectagle shapes:

        sf::RectangleShape grass;
        grass.setTexture(&grassTexture);
        grass.setSize(sf::Vector2f(50, 50));
       
        sf::RectangleShape water;
        water.setTexture(&waterTexture);
        water.setSize(sf::Vector2f(50, 50));

        sf::RectangleShape lava;
        lava.setTexture(&lavaTexture);
        lava.setSize(sf::Vector2f(50, 50));

Then and array for tiles:

sf::RectangleShape map[16][12];

And I put like this:

map[0][0] = grass;
map[0][1] = grass;
.....
map[15][11] = lava;

It takes a lot of space for all this.

Next I made and array for water collision and put in it all water tiles:

sf::RectangleShape waterCollision[56] = {map[1][1] , map[1][2] ,map[1][4]...};

And the at the end I draw them:

                for(int d=0; d < 16; d++)
                        {
                                for(int f=0; f < 12; f++)
                                {
                                        window.draw(map[d][f]);
                                }
                        }

All this works but is there any easier way to assign water,lava,grass to tiles?
And is there any easier way to do water collision?

Sorry for my english.

Graphics / Tiled map with vectors

« on: September 03, 2013, 04:30:09 pm »

I made this tiled map with vectors.
First I made vectors for 4x4 map:

        std::vector< std::vector<int> > map(4, std::vector<int>(4));
    // Define the map
    map[0][0] = 0;
    map[0][1] = 1;
    map[0][2] = 0;
    map[0][3] = 0;
    map[1][0] = 0;
    map[1][1] = 0;
    map[1][2] = 0;
    map[1][3] = 0;
    map[2][0] = 0;
    map[2][1] = 0;
    map[2][2] = 0;
    map[2][3] = 0;
    map[3][0] = 0;
    map[3][1] = 0;
    map[3][2] = 0;
    map[3][3] = 1;
 

Then I made sprites for grass and water:

        std::vector<sf::Sprite> tiles(2);
        tiles[0] = sf::Sprite(grass);
        tiles[1] = sf::Sprite(water);

And then draw it:

                        for (int x = 0; x < map.size(); x++)
                        {
            for (int y = 0; y < map[x].size(); y++)
                        {
                int tileId = map[x][y];

                                tiles[tileId].setPosition(x * 100, y * 100);
                                window.draw(tiles[tileId]);
            }
        }

I also added a rectangle and movement.
Now I don't know how to acces water tiles and add collision to them.
Sorry for my english.

Graphics / Ball speed

« on: August 22, 2013, 04:36:44 pm »

Here is my code:

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

int main()
{
        //Creation
        sf::RenderWindow window(sf::VideoMode(800, 600), "SFML Game");
        //60 FPS
        window.setFramerateLimit(60);

        window.setKeyRepeatEnabled(false);
        //States for buttons and events
        sf::Event event;
        bool play= true;
       
       
        //Vars
        int ballXVelocity = 6;
        int ballYVelocity = 6;

        //Render shapes
        sf::CircleShape ball;
        ball.setRadius(25);
        ball.setPosition(375,275);
        ball.setFillColor(sf::Color::Blue);

        //Game loop
        while(play == true)
        {
                //EVENTS
                while (window.pollEvent(event))
                {

                        if(event.type == sf::Event::Closed)
                        {
                                play = false;
                        }
                        if(event.type == sf::Event::KeyPressed && event.key.code == sf::Keyboard::Escape)
                        {
                                play = false;
                        }

               
                }


                //LOGIC
               
                ball.move(ballXVelocity, ballYVelocity);

                if(ball.getPosition().x < 0 || ball.getPosition().x > 750) ballXVelocity = -ballXVelocity;
                if(ball.getPosition().y < 0 || ball.getPosition().y > 550) ballYVelocity = -ballYVelocity;



                //RENDERING

                        window.clear();

                        window.draw(ball);

                        window.display();

        }

        //Clean up
        window.close();

    return 0;
}

I made a ball with x velocity = -6 and y velocity = -6
I want now to increase x and y velocity by 1 every 5 second.
How can I do that?
I hope it's not a dumb question and you understand me.

Yes, it's the breakout game.

How do you mean store them in a container?

I'm trying to make a game but I have problem with graphics.
I don't know the name of the game but it's the one with paddle and ball where you need to destroy the bricks.
I made the paddle and ball moving and now I don't know how to make the bricks.
If you need pictures or code comment please.

if(t0.getGlobalBounds().intersects(otherShape.getGlobalBounds())) {
// do something since targetShape has collided with t0 shape.
}

I already did that and it's not working.
My shape can't move.
Btw its position is 0,0 as t1(grass) position, it doesn't draw on t0(water) at the start.

Graphics / Array and tiles

« on: July 25, 2013, 12:29:37 pm »

I made 2 pictures and loaded them:

        sf::Texture grass;
        if(!grass.loadFromFile("Data/grass.png"))
        {
                return EXIT_FAILURE;
        }

        sf::Texture water;
        if(!water.loadFromFile("Data/water.png"))
        {
                return EXIT_FAILURE;
        }

Rendered:

        sf::RectangleShape t1;
        t1.setSize(sf::Vector2f(50, 50));
        t1.setTexture(&grass);
       
        sf::RectangleShape t0;
        t0.setSize(sf::Vector2f(50, 50));
        t0.setTexture(&water);

Then I made this multidimensional array called tile:

sf::RectangleShape tile[4][4] = {
                {t1,t1,t1,t1},
                {t1,t0,t0,t0},
                {t1,t1,t1,t1},
                {t0,t0,t0,t0}
        };

and added those 2 pictures into it.
Now when I draw this:

                        window.clear();

windw.draw(tile[0][0]);
                       
                        window.display();

Program draws the t1 rectangle shape.

So, my question is how I can draw all those 16 items in array so they are placed like in array.
I tried to make a for loop like this:

for(int x=0;x<4;x++)
{
      for(int y=0;y<4;y++)
      {
            window.draw(tile[x][y]);
      }
}
 

Program just draws the tile[3][3] which is t0;

I hope you understand my english and sorry if this is a stupid question.

I have a good understanding of c++.
Just I have always been using class in main.cpp not in separated file.And my question is how to draw everything in there.

I want to put all my drawings in separated file.
Can I do that?
How to do that?
I want all my logic and events in main.cpp.
But drawing in one class named eg Drawing, but I want that class to be in separated file.

I used tiled http://www.mapeditor.org/ for making a tiled map and saved it as xml.
So now how I can use this xml to draw it in the game?
I can make it csv too.
