Graphics / How can i slow down the rate my projectiles fire.

« on: April 23, 2017, 11:20:52 pm »

I have a function that draws and moves a projectile automatically based on if a certian monsters are in range or not. The problem I am having is that when the monsters in range it draws it so many times its almost like a line. I have been at this for so many hours im about to throw in the towel. I have tried using the clock but its just not working out.

This function checks if the monster is in range and pushes back a vector of bullets.

 for (int i = 0; i < mymonsters.size(); i++)
        {
                for (int k = 0; k < myicetower.size(); k++)
                {
                        if (mymonsters[i].checkCollision(myicetower[k].getRadius(), myicetower[k].getPositionX(), myicetower[k].getPositionY()))
                        {

                                //      BulletClass bulletshot;
                                bulletshot.setPosition(myicetower[k].getPositionX(), myicetower[k].getPositionY());
                                bullet.push_back(bulletshot);
                        }
                }
        }

 

This function draws it to the window. But it draw it so many times its ridiculous

sf::Vector2f fire(1.f, 1.f);
        for (int i = 0; i < bullet.size(); i++)
        {
                //if(function.checkCollision(myicetower, mymonsters))
                {
                        bullet[i].fire(fire);
                        bullet[i].draw(window);
                }
        }
       
        window.display();
}

Any help would be great.

Can i create two shapes with sfml and draw them together all in the same class?


void TowerA::draw(sf::RenderWindow & window)
{
   window.draw(sprite)
   window.draw(circle)
   window.draw(circle2)
}

Graphics / Trying to create a tilemap in a class.

« on: April 16, 2017, 08:11:38 pm »

In my constructor I have my TileMap object definition. But other functions of the class cant use the map. I tried defining map in the header but it really dosent work like that. I have a render function that does all my rendering like window.clear and window.draw(map). I also have a processEvents that processes all the events. I cant pass it to the function as a parameter either.

        window.create(sf::VideoMode(528, 256), "Tilemap");
                // define the level with an array of tile indices
        const int level[] =
        {
                        4, 4, 4,  4,  4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4,
                        4, 4, 4,  4,  4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4,
                        4, 4, 4,  4,  4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4,
                        12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12,
                        4, 4, 4,  4,  4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4,
                        4, 4, 4,  4,  4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4,
                        4, 4, 4,  4,  4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4,
                        4, 4, 4,  4,  4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4,
                };

                //create the tilemap from the level definition
        TileMap map;
        if (!map.load("tileset.png", sf::Vector2u(33, 33), level, 16, 8))
                        std::cout << "Cant upload map" << std::endl;
}

Window / resizing a window by dragging it and using sf::view

« on: April 16, 2017, 01:46:17 am »

I am trying to have my map stretch when i either full screen it using the box or slowly drag the borders using sf view. I have tried various methods doing that however they all failed. The window resizes but the map stays the same size.  Here we have

 

case sf::Event::Resized:
        if (event.type == sf::Event::Resized)
        {
                sf::FloatRect visibleArea(0, 0, event.size.width, event.size.height);
                window.setView(sf::View(visibleArea));
                window.draw(map);
                /*sf::View view(sf::FloatRect(0, 0, 1000, 600));                               
                window.create(sf::VideoMode(event.size.width, event.size.height, 32),"Tilemap");
                view.setSize(event.size.width, event.size.height);
                window.setView(view);
                window.draw(map);*/
                std::cout << "Resized" << std::endl;
        }
        break;

General / Fallens tmxlite question.

« on: April 06, 2017, 03:14:09 am »

I am trying to use tmxlite to parse a tmx file from tiled. Has anyone used his parser before. He has a visual studio project included in his github but compiling to test it i get the error /user/....../x64/bin/ReleaseStatic/libtmxlite-slib. Cannot find path. I didn't see such a lib included in his zip file. Do i need to make this myself....
