Window / Re: Drawing sprite while passing ByRef RenderWindow

« on: June 13, 2014, 02:23:32 pm »

The Bullet contructor is :

Bullet::Bullet(){
        this->MoveVelocity = 5;
        this->posX = 0;
        this->posY = 0;
        this->dead = true;

        if (this->bulletTexture.loadFromFile("img\\bullet\\bullet.png"))
        {
                this->bulletTexture.setSmooth(true);
                this->bulletTexture.setRepeated(true);

                this->bulletSprite.setTexture(this->bulletTexture);
                //this->bulletSprite.setScale(0.7F, 0.7F);
        }
}            


Bullet::Bullet(int x, int y){
        this->MoveVelocity = 5;
        this->posX = x;
        this->posY = y;
        this->dead = false;
        if (this->bulletTexture.loadFromFile("img\\bullet\\bullet.png"))
        {

                this->bulletTexture.setSmooth(true);
                this->bulletTexture.setRepeated(true);

                this->bulletSprite.setTexture(this->bulletTexture);
                this->bulletSprite.setColor(sf::Color::Red);
                //this->bulletSprite.setScale(0.7F, 0.7F);
        }
};

 
//BULLET piece of HEADER:

#ifndef Bullet_H
#define Bullet_H

class Bullet{
public:
        Bullet();
        Bullet(int x, int y);
        sf::Sprite retBullet();
        void Explode();
        void SetPos(int x, int y);
        bool isDead();
protected:
private:
        sf::Texture bulletTexture;
        sf::Sprite bulletSprite;

        int posX;
        int posY;

        int MoveVelocity;

        bool dead;
};
#endif

 

it is initialized and stored well, on debug i don't receive error  on texture or on sprite it seems that the procedure draws it correctly but i don't see it

Window / Drawing sprite while passing ByRef RenderWindow

« on: June 12, 2014, 10:00:47 am »

The problem is that if I pass the RenderWindow ByRef to function I don't see the bullet but if I create the bullet in main.cpp I see the bullet, on debug i see that the programs enter in BULLET DRAWING and generates NO error, here is the piece of code:
in Main I have

while (window.isOpen())
        {
                ControlKeyPress(&window, &event);  

                window.clear();
                window.draw(game.getBACKSprite());
                window.draw(me.retPlane());

                me.DrawBullets(&window);
 
                window.display();
        }
 

The draw function is :

void MyPlayer::DrawBullets(sf::RenderWindow *window){
        int usB = 0;
        for (int i = 0; i < 6; i++){
                if (!this->bullet[i].isDead()){
                        window->draw(this->bullet[i].retBullet());  // BULLET DRAWING
                        usB++;
                }
        }
        this->usingBullet = usB;
};

 
sf::Sprite Bullet::retBullet(){
        if (!this->dead){
                if (this->posX <= 800 - this->MoveVelocity)
                        this->posX += MoveVelocity;
                else
                        this->dead = true;

                this->bulletSprite.setPosition((float)this->posX, (float)this->posY);
        }
        return this->bulletSprite;
};

Window / Re: Detect multiple keypress

Use a couple of bool variables to hold state information about keys.
So, when you get the event that down is pressed, set "down_pressed = true;" and when it is released set it to false.
Do the same for the other keys. Then to check if you are going down and right, check "if (down_pressed && right_pressed) { down_right_do_stuff(); }" etc.

I can't do that because in if block (event.type == sf::Event::KeyPressed) it never catch the right key press, it only catch the down key press when i hold both right and down keys, so a bool is useless here.
I hope I understand what you've suggested to me.
P.S. Sorry for my poor english

Window / Detect multiple keypress

« on: June 09, 2014, 02:03:32 pm »

Hi,
I want to detect multiple keypress like downArrow and RightArrow I have the code:

 if (event.type == sf::Event::KeyPressed)
                        {
                                if (event.key.code == sf::Keyboard::Key::Escape)
                                        window.close();

                                if (event.key.code == sf::Keyboard::Key::Right)
                                        me.MoveXAxis(1);
                                else if (event.key.code == sf::Keyboard::Key::Left)
                                        me.MoveXAxis(-1);

                                if (event.key.code == sf::Keyboard::Key::Up)
                                        me.MoveYAxis(-1);
                                else if (event.key.code == sf::Keyboard::Key::Down)
                                        me.MoveYAxis(1);
                        }
 

As you can see up-down and left-right are in different IF blocks but if I press Down-Right it only goes on DOWN how can I intercept the right key press ? so the plane can move on diagonal...
Thanks.
