Graphics / Re: How do you return a vector2f from a function.

« on: April 24, 2017, 02:51:48 am »

My function that returns a sf::vector2f is from the functions class. I simple have created a object called function to use it.

In my game class im tryiing to use this function to return a vector2f so i know where my bullet needs to go. However i get the error term does not evaluate to a function taking two arguments.

Graphics / How do you return a vector2f from a function.

« on: April 24, 2017, 12:42:11 am »

So im trying to return a vector2f from a function. So i can use it in a function in another class that takes a vector2f.


if i have the function

template <typename t, typename u>
        sf::Vector2f checkDirection(std::vector<t>  &vtower, std::vector<u>  &vmonster)
        {
                for (int i = 0; i < vmonster.size(); i++)
                {
                        for (int k = 0; k < vtower.size(); k++)
                        {
                                if (vmonster[i].getPositionX() + vmonster[i].getRadius() + vtower[k].getRadius() > vtower[k].getTowerRangePositionX()
                                        && vmonster[i].getPositionX() < vtower[k].getTowerRangePositionX() + vmonster[i].getRadius() + vtower[k].getRadius()
                                        && vmonster[i].getPositionY() + vmonster[i].getRadius() + vtower[k].getRadius() > vtower[k].getTowerRangePositionY()
                                        && vmonster[i].getPositionY() < vtower[k].getTowerRangePositionY() + vmonster[i].getRadius() + vtower[k].getRadius())
                                {
                                        return direction(vmonster[i].getPositionX(), vmonster[i].getPositionY());
                                       
                                       
                                }

                        }
                }
        }

Im trying to return a vector2f so i can use it in this function here

for (int i = 0; i < bullet.size(); i++)
                {
                       
                        bullet[i].fire(function.checkDirection(myicetower, mymonsters)); //fire takes a vector2f
                }

Graphics / Re: Can you have two different global textures in different classes.

I just wanna see my textures while i'm making my game instead of white boxes. Then when the game is finished ill make a resource management class

Oh man you are a genius that's exactly what was going on!!!! Thank you so much. You saved me hours more of a heacache!!!

« on: April 22, 2017, 06:16:43 am »

I have a 2 classes. I have a tower class and I have a monster class. The default constructor automatically sets a position for the tower. I store the classes in a vector and run a function that returns the value of the towers x position. I can clearly see on my screen that the tower is not in the 0,0 coordinate, but it says it is anyway.

void checkcolission(TowerA tower)
{
    if (tower.getLeft() > monsterSprite.getPosition().x) /*&& tower.getTop() < monsterSprite.getPosition().y && tower.getBottom() > monsterSprite.getPosition().y*/
    {
        //std::cout << "#($)(#%*#%U#*(%*#%*#%" << std::endl;
    }
    std::cout << tower.getPositionX() << std::endl;

}

public://in my tower class
TowerA()
{
    spritetower1.setPosition(100, 50);
    towerRange.setPosition(getPositionX(), getPositionY());
}



//This is in my game class with push_backed vectors of the class
for (int i = 0; i < mymonsters.size(); i++)
{
    for (int k = 0; k < myicetower.size(); k++)
    {
        mymonsters[i].checkcolission(myicetower[k]);

    }
}

I know the best thing to do is create a resource manager, and when i get there i get there. But my question is if i have a sf::Texture X declared globally in one cpp and assigned to a sprite in that cpp.  Can i have sf::Texture Y declared globally in another cpp and assigned to a sprite in that cpp. It keeps telling me that texture is already defined.

Window / window.draw(spritename) drawing sprites over and over in a loop. Bad??

« on: April 20, 2017, 12:29:53 am »

I havent loaded textures in until i get my resource management class going. Drawing the sprites over and over in a loop dosent seem to stress the computer that much. But if there is no need to draw why draw. For example I have a render function that draws all my monsters and sprites through arrays while the window is open.

for (int i = 0; i < myfirearray.size(); i++)
        {
                window.draw(myfirearray[i]);
        }

Now this will tick through the game loop and keep drawing and drawing and drawing these sprites over and over. How bad is this. Should i not draw these in a loop? I currently don't have textures yet, because I know there not lightweight and i want to make a management class. Im not looking to create the most amazing best game in the world something simple and educational. But i dont wanna run into a problem later.

Uggh i realize now that textures dont survive ......... I wonder if im going to run into an raii problem later on when i try to handle this.

I have a draw class that creates and returns a sprite. However when i use the assignment operator all i get is a white square for the newly created sprite. Simply creating a sprite without using the function works so i know the code in my function is good.

sf::Sprite & Draw::drawTowerSprite()
{
        std::cout << "cake" << std::endl;
        sf::Texture towertexture;
        if (!towertexture.loadFromFile("tower.png", sf::IntRect(0, 0, 32, 32)))
        {
                std::cout << "Couldnt load Monster" << std::endl;
        }
        sf::Sprite spritetower1;
        spritetower1.setTexture(towertexture);
        spritetower1.setPosition(50, 50);
        return spritetower1;
}

// then in another function

Draw objects;
   newsprite = objects.drawTowerSprite(); // this will create the sprite but a white square. Does it have no texture?
