This in another problem that I just encountered, variable changing value in event space key pressed wont execute and I dont know why.

//VARIABLES
bool ship1Position;
bool ship2Position;
bool dragShip1 = false;
bool dragShip2 = false;
 

                case sf::Event::KeyPressed:
                {
                    switch(event.key.code)
                    {
                        case sf::Keyboard::Space:
                            if(dragShip1)
                                ship2Position = true;
                                dragShip1 = false;
                            break;
                    }
                    break;
                }

                case sf::Event::KeyReleased:
                {
                    switch(event.key.code)
                    {
                        case sf::Keyboard::Space:
                            break;
                    }
                }
            }
       }  

        window.clear();
        ship1Position = true;

        while(ship1Position)
        {
            window.draw(ship1);
            dragShip1 = true;
            ship1Position = false;

        }

        while(ship2Position)
        {
            window.draw(ship2);
            dragShip2 = true;
            ship2Position = false;
        }

Thanks, so back to my current problem again.

How to make the ships to associate with the grids? Please give some examples if possible.

Since you know the position of the ship you could take an array or better a vector and calculate the correct indices based on the position.
With these indices you can set the bool variable on the vector to true or maybe use an integer (or char) to indicate states such as (ship, hit, water, etc).

Thank you for the idea. Now I see where I'm heading to.

In a meanwhile, I try to change the orientation of the ship from horizontal to vertical using RMB while LMB is pressed. It went good, but I've encountered some problems:
1. When changing the orientation from horizontal to vertical, the ship went far off the mouse pointer (Attached pic #1)
2. When I try to drag the ship after changing the ship's orientation, the ship went a slight off the mouse pointer, but still dragable (Attached pic #2)

these are what I've wrote

if (event.type == sf::Event::MouseButtonPressed && event.mouseButton.button == sf::Mouse::Right)
            {
                mouseClickedRight = true;
                if (draggingShip1 == true) //when LMB is pressed at the same time
                    ship1.setRotation(90);
                    ship1.setPosition(sf::Vector2f(mouseX,mouseY));

            }
 

How do I get the ship exactly under the mouse pointer even after I've changed its orientation?

First of all, I'd suggest you trying to make this game in OOP(object oriented programming), then the code will be a whole lot easier to modify, arrange and understand to other people. Also, then you could make classes, such as ship, or tiles of your map. With this logic it will be easier to make this game.

Actually, I'm taking the OOP subject next semester. But I'll take a look on it. Thank you

Hi, I just started using SFML a week ago and there is this assignment I need to complete which involve writing a Battleship game using SFML library. So far, I was able to complete the graphics and just done dealing with drag and drop all the ships. These are what I've wrote since 3 days ago:

http://codepad.org/W7cG5vsx

^Posted the code there cause it's more than 300 lines

These are what I've achieved (still to far away from completing the assignment  ) :
-Draw grids and ships
-Figured how to drag and drop the ships

This is the current problem which I focus on and don't know how to solve:
-Drop the ships onto the grids and assign their properties to the grids (This is for attacking and getting attacked)

If you don't get the idea, I'm bad in explaining things 
If you do get the idea, please help me out if you have any solutions or ideas 

Attached file is the screenshot of the program (I've moved the ships onto the grids)

Thank you
