General / intersection between sprites from different classes

« on: April 19, 2018, 02:41:33 pm »

Hello guys I am struggling while trying to make this intersection between my tree and rock sprite but they are in different classes and I don't know how to make the command in this situation since I just started using classes with sprites.

this is the tree class:

class Tree
{
public:
        Tree(string treerectory)
        {
                t.loadFromFile(treerectory);
        }
       
        void treeTexture()
        {
                for (size_t i = 0; i < 1000; i++)
                {
                        tree[i].setTexture(t);
                        tree[i].setScale(1, 2);
                }
        }

        void treePosition()
        {
                for (size_t i = 0; i < 1000; i++)
                {
                        tree[i].setPosition(rand() % 10560 + 0.f, rand() % 10560 + 0.f);
                }
        }

        void treeDraw(RenderWindow &app)
        {
                for (size_t i = 0; i < 1000; i++)
                {
                        app.draw(tree[i]);
                }
        }

        void treeSelfCollision()
        {
                srand(time(0));

                for (size_t i = 0; i < 1000; i++)
                {
                        if (tree[i].getGlobalBounds().intersects(tree[1000].getGlobalBounds()))
                        {
                                tree[i].move(rand() % 15 - 15, rand() % 15 - 15);
                        }
                }
        }

private:
        Texture t;
        Sprite tree[1000];
};
 

and this is the rock class:

class Rock
{
public:
        Rock(string rockrectory)
        {
                r.loadFromFile(rockrectory);
        }

        void rockTexture()
        {
                for (size_t i = 0; i < 1000; i++)
                {
                        rock[i].setTexture(r);
                }
        }

        void rockPosition()
        {
                for (size_t i = 0; i < 1000; i++)
                {
                        rock[i].setPosition(rand() % 10560 + 0, rand() % 10560 + 0);
                }
        }

        void rockDraw(RenderWindow &app)
        {
                for (size_t i = 0; i < 1000; i++)
                {
                        app.draw(rock[i]);
                }
        }

        void rockSelfCollision()
        {
                for (size_t i = 0; i < 1000; i++)
                {
                        if (rock[i].getGlobalBounds().intersects(rock[1000].getGlobalBounds()))
                        {
                                rock[i].move(rand() % 15 - 15, rand() % 15 - 15);
                        }
                }
        }

private:
        Texture r;
        Sprite rock[1000];
};
 

I want to make a function to check if the tree and the rock are intersected, how do I do?

General / tree sprite doesn't draw

« on: April 18, 2018, 10:31:12 pm »

hello, I have a problem, my trees don't spawn in the map, this is the tree class:

class Tree
{
public:
   Tree(string directory)
   {
      t.loadFromFile(directory);
   }
   
   void treeTexture()
   {
      for (size_t i = 0; i < 1000; i++)
      {
         tree.setTexture(t);
         tree.setScale(1, 2);
      }
   }

   void treePosition()
   {
      for (size_t i = 0; i < 1000; i++)
      {
         tree.setPosition(rand() % 10560 + 0, rand() % 10560 + 0);
      }
   }

   void treeDraw(RenderWindow &app)
   {
      for (size_t i = 0; i < 1000; i++)
      {
         app.draw(tree);
      }
   }

private:
   Texture t;
   Sprite tree[1000];
};

and this is the main function:

Tree tree("shapes/world/tree.png");

tree.treeDraw(app);

can you tell me why I can't see them?

General / put the player at the center of the view from another class

« on: April 18, 2018, 08:43:55 pm »

hello guys I am struggling with this error:

no instance of overloaded function "sf::View::setCenter" matches the argument list

that comes when I do this:


   void playerposition()
   {
      player.getPosition();
   }

from my player class and then in the main function I write this:

Player p1;

p1.playerposition();

anyone can explain why the error?

Graphics / unhandled exception stack overflow in sprite

« on: April 07, 2018, 02:03:50 pm »

yesterday I wrote this code to make trees spawn randomly anywere in the map:

for (int i = 0; i < 1000; i++)
        {
                tree[i].setTexture(tr);
                tree[i].setPosition(rand() % 10560 + 0, rand() % 10560 + 0);
                tree[i].setScale(1, 2);
        }

and then

for (int i = 0; i < 1000; i++)
                {
                        app.draw(tree[i]);
                }

-------------------------------------

But today i wrote that again for yellow flowers:

        for (int i = 0; i < 1000; i++)
        {
                yellow_flower[i].setTexture(y_f);
                yellow_flower[i].setPosition(rand() % 10560 + 0, rand() % 10560 + 0);
        }

and then

                for (int i = 0; i < 1000; i++)
                {
                        app.draw(yellow_flower[i]);
                }

but when I added these new loops, this error occurs to me:

Unhandled exception at 0x01017D59 in MyGame.exe: 0xC00000FD: Stack overflow (parameters: 0x00000000, 0x00402000).

Hi, I have an image that is a tree and I want to make it so that it spawns 500 trees all around the map, but I don't know how to draw multiple times the same image, I know that you need vectors and for loops, but I didn't understand much about how that works, can someone explain how to do that? thanks in advance

General / sprite rect for animations makes the character change position

« on: February 02, 2018, 01:04:37 pm »

help guys I am trying to get an animated sprite for the character of my game that gets a rect of the sprite which changes if he goes right,left,up or down.
here is the code:

            if (e.key.code == sf::Keyboard::W) {
               character.setTextureRect(IntRect(-30,97,60,30));
               character.move(0, -5);

            }

the problem here is that when I press "w" the character changes position a bit to the right and doesn`t stay in the position where the previous frame of the animation was, the movement works correctly after it goes right. hulp plz.

General / Delay between commands

« on: January 29, 2018, 01:18:39 am »

Hello, I need to do an animation of a sprite that goes darker and darker until black so I set the color darker and darker with a sleep command every darker color, like this:

If (keyboard::iskeypressed(keyboard::return)) {
Sprite.setcolor(color(200,200,200));
Sleep(seconds(1));
Sprite.setcolor(color(100,100,100));
Sleep(seconds(1));
Sprite.setcolor(color(0,0,0));
}

This doesn't work, when I click return there is 1 delay that is the sum of all the delays I put and then only the last color is applied. Please help
