General / Vector of shapes

« on: February 25, 2018, 03:04:52 pm »

I had been doing this in arrays and was working completely fine but when I tried to do the same thing with vector I am getting errors.

error: 'class std::vector<sf::CircleShape>' has no member named 'setRadius' and 'setFillColor'

In food.h :

class Food{
private:
     std::vector<sf::CircleShape> food[81];
public:
    Food(int rad);
};
 

In food.cpp:

#include "food.h"

Food::Food(int rad){
    for(int i=0;i<81;i++){
        food[i].setRadius(rad);
        food[i].setFillColor(sf::Color(10,200,10));
        }
}

Graphics / Invisible sprite when "move keys" continuously pressed

« on: February 23, 2018, 02:24:59 pm »

Hey Guys .. don't know what exactly happens but sprite(head) becomes invisible when I move it left and right by continuously pressing the left right keys but  it is visible while moving up and down.
 
code ::

if( sf::Keyboard::isKeyPressed(sf::Keyboard::Left)){
        if(head.getPosition().x > head.getSize().x/2){
            position.x -= speed * deltaTime;
            head.setRotation(0.f);
        }
    }

    else if(sf::Keyboard::isKeyPressed(sf::Keyboard::Right)){
        if(head.getPosition().x < window.getSize().x-head.getSize().x/2){
            position.x += speed *deltaTime;
            head.setRotation(0.f);
        }
    }

    else if(sf::Keyboard::isKeyPressed(sf::Keyboard::Down)){
        if(head.getPosition().y < window.getSize().y-head.getSize().y/2){
            position.y += speed *deltaTime;
            head.setRotation(90.f);
            if(!faceRight)
                head.setRotation(270.f);
        }
    }
    else if(sf::Keyboard::isKeyPressed(sf::Keyboard::Up)){
        if( head.getPosition().y > head.getSize().y/2){
            position.y -= speed *deltaTime;
            head.setRotation(270.f);
            if(!faceRight)
                head.setRotation(90.f);
        }
    }
