General / Problem spawning multiple enemies

« on: February 22, 2022, 10:08:55 pm »

Hello!

I have a problem whit a game that I am developing, i want to spawn random enemies across time, but only one of them appears in screen. Someone can help me?

I made this classes, entidad(entity), entidadmanager(entitymanager) and partida.

entidad::entidad() {
       
        static Texture *tex = 0;
        if(tex == 0){
                tex = new Texture();
                tex->loadFromFile("meteorito.png");
        }
        Sprite ast;
        ast.setTexture(*tex);
        m_sprite = ast;
        m_sprite.setScale(0.03f,0.03f);
        m_pos.x = rand () % 800 + 30;;
        m_pos.y = -10;
        m_sprite.setPosition(m_pos.x,m_pos.y);
}
void entidad::actualizar(){
        m_sprite.move(0,0.3);
}
void entidad::dibujar(RenderWindow &w){
        w.draw(m_sprite);
}

Vector2f entidad::verposi(){
        Vector2f charpos = m_sprite.getPosition();
        return charpos;
}

entidadmanager::entidadmanager() {
        vector<entidad> v;
        m_v = v;
        Clock reloj;
        m_reloj = reloj;
}
void entidadmanager::actualizar(){
       
        if(m_reloj.getElapsedTime().asMilliseconds() >= 1000){
                entidad aux;
                m_v.push_back(aux);
        }
        for(size_t i=0;i<m_v.size();i++) {
                m_v[i].actualizar();
                Vector2f charaux;
                charaux = m_v[i].verposi();
                if(charaux.y > 900){
                        auto it = next(m_v.begin(),i);
                        m_v.erase(it);
                }
        }
        m_reloj.restart();
}
void entidadmanager::dibujar(RenderWindow &w){
        for(size_t i=0;i<m_v.size();i++) {
                entidad aux;
                aux = m_v[i];
                aux.dibujar(w);
        }

Partida::Partida() {
        nave n1;
        entidadmanager met;
       
}
bool fuera(disparo &d){
        Vector2f p = d.verPosicion();
        if(p.x<0 or p.x>1600) return true;
        if(p.y<0 or p.y>900) return true;
        return false;

}
void Partida::actualizar(juego &j) {
        n1.actualizar();
        met.actualizar();
        if(n1.dispara()) vd.push_back(n1.dispGen());
        for(disparo &d : vd) d.actualizar();
        auto it2 = remove_if(vd.begin(),vd.end(),fuera);
        vd.erase(it2,vd.end());
}
void Partida::dibujar(RenderWindow &w, Sprite fondo) {
        w.clear(Color(220,220,180,255));
        w.draw(fondo);
        n1.dibujar(w);
        met.dibujar(w);
        for(disparo &d : vd) d.dibujar(w);
}

I guess that the problem is in entidadmanager::actualizar, but I can`t find it.

General / Spawning random enemies

Hello, im new using SFML. I'm doing a proyect for my carreer, the proyect consist in a 2D game, where the user plays as a spaceship, and you have to destroy or avoid asteroids.

The program compiles and execute normally, but it has a problem, and is that the asteroids does not draw in the screen, and I don`t now how to fix it.

For the asteroids I use 2 classes, Entidades(entity) and entidadManager(EntityManager).

///ENTIDAD

Sorry if  the post it`s a bit long (a bit too long haha) but it`s my first one.

Any help is appreciated
