Graphics / Disable click through overlapping shapes?

« on: April 20, 2019, 05:42:31 pm »

I am really close to building my project but I am encountering one simple problem. I have a rectangle on which I have use the GetGlobalBounds to check if mouse clicks on it. Now I am drawing over another Rectangle over that rectangle and using GetGlobalBounds on the overlapping Rectangle. Now when i click on the overlapping one, the command for the original Rectangle is executed instead of the one that is overlapping. How can I prevent this?

Graphics / Drawing inside the Game loop / RectangleShape?

« on: April 17, 2019, 10:49:16 am »

I am using a switch to check the position of the mouse click and then display the sprite at the clicked location.
I am using this. But  the sprite comes for one frame and then goes away. also i have placed the switch inside the main game loop. So is there a way I can fix the Sprite once it is spawned so that it doesnt despawn. Or is there a way so that i can place my sprite automatically Inside the rectangle and also check if cell_1 == cell_2 == cell_3 so the player wins

case Event::MouseButtonPressed:

                                if (event.mouseButton.button == Mouse::Left) {

                                        if (Cell_1.getGlobalBounds().contains(window.mapPixelToCoords(sf::Mouse::getPosition(window)))) {
                                       
                                                cout << "Cell 1" << endl;
                                                window.draw(sprite);
                                                sprite.setPosition(Vector2f(125.f, cell_height));
                                                window.display();
                                               

                                               
                                        }

System / Detecting a mouse click inside a "Not Defined" Rectangle.

« on: April 16, 2019, 07:08:15 pm »

It sounds weird but i have created a big box with three rectangles. The three rectangles are shown in picture.
their starting points are :
1.Halfway of the box vertically.                                        Size :  750,200  (Purple colored)
2.Halfway of the box horizontally                                     Size :  200,600  (Red colored)
3.In the middle where the 2 rectangles collide                  Size :  250,200  (Orange colored)

now i have made a grid for TIC TAC TOE  without defining all the 9 cells one by one. Now I have detect when the user clicks on cell 1 (look at the picture) and so on. How can I detect that?

System / How to detect if mouse clicked inside a certain box or rectangle

« on: April 16, 2019, 01:05:33 pm »

By box or rectangle I do not refer to the rect drawn by me. I want to know if a user clicked in a place. I am making a tic tac toe program and I want to register the click. i have been using this

                Vector2i winpos = Mouse::getPosition(window);
                int loc_x = winpos.x;
                int loc_y = winpos.y;

                INPUT:
                if (Mouse::isButtonPressed(Mouse::Left)) {
                       

                        if (72 < loc_x < 250 && 600 < loc_y < 500) {

                                cout << "works" << endl;
                               
                        }

                }
               
 

also i have placed this code inside the while loop
it should cout "works" in the cmd when i click in the first block but gives me "works" everytime i click inside
the window. it should not do that. it should only gimme works if mouse clicks in 1st cell/block.
look picture for clarification.

Graphics / Failed to load image.

« on: April 15, 2019, 01:28:23 pm »

so i am very new to SFML (less then 24 hrs) and i have encountered with a weird problem. I am trying to load a texture and when i run my code, the cmd shows "failed to load ... " in the very beginning and then prints all sort of weird random gibberish stuff. I am using visual studio 2017 and SFML 2.5 . Also i found my working dir by using system(dir) and placed my png there but still doesnt work. also if i remove the "if condition" everything is fine. Here is my code :

#include <SFML/Graphics.hpp>
#include "iostream";
 using namespace std;
 using namespace sf;
 int main()
 {
    RenderWindow window(VideoMode(1000, 1000), "Chiggy's Tic Tac Toe!");
    CircleShape shape(100.f);
    shape.setFillColor(Color::Blue);
    Texture texture;
    if (!texture.loadFromFile("D:\Developement\VisualStudio\sfml\try\Project0\Project0\mad.png")) {  
         
           cout<<"Mario failed to load horribly"<<endl; system("pause"); //return EXIT_FAILURE; }

     while (window.isOpen()) {

           Event event;
           
            while (window.pollEvent(event)) {
                 if (event.type == Event::Closed)
                 window.close();
}

 window.clear(Color::Black);
 window.draw(shape);
 window.display();
}
return 0; }
