So guys I'm making a shooting game in SFML where the player sprite shoots at 5 enemies who are randomly generated on the screen once destroyed. I was just testing out my code and I noticed that my bullet class isn't working. Everytime I press spacebar the sprite slows down but no bullets shoot. I am fairly new to SFML (started last week) so I guess I made a very stupid mistake (and also I might be following an old tutorial. I couldn't find a viable tutorial to rely on so I chose an old but good one). Here's the code :-
(dunno how to do the code thing)
Bullet.h :-
#pragma once
#include <SFML/Graphics.hpp>
#include "Player.h"
class Bullet {
public:
Bullet(sf::Vector2f size, sf::Color color) {
bullet.setSize(size);
bullet.setFillColor(color);
}
void setPosition(sf::Vector2f position) {
bullet.setPosition(position);
}
void playerShoot(Player& player, float velocity){
rotation = player.getRotation();
fire.x = sin(rotation * (3.14 / 180)) * velocity;
fire.y = -cos(rotation * (3.14 / 180)) * velocity;
bullet.move(fire);
}
void enemyShoot() {
}
void draw(sf::RenderWindow& window) {
window.draw(bullet);
}
int getTop() {
return bullet.getPosition().x;
}
int getRight() {
return bullet.getPosition().x + bullet.getSize().x;
}
int getBottom() {
return bullet.getPosition().y + bullet.getSize().y;
}
int getLeft() {
return bullet.getPosition().x;
}
private:
sf::RectangleShape bullet;
sf::Vector2f fire;
double rotation;
};
Player.h :-
pragma once
#include<SFML/Graphics.hpp>
class Player {
public:
Player(sf::Vector2f size) {
player.setSize(size);
player.setRotation(0);
}
sf::Vector2f getSize() {
return player.getSize();
}
void setPosition(sf::Vector2f position) {
player.setPosition(position);
}
sf::Vector2f getPosition() {
return player.getPosition();
}
void setOrigin(sf::Vector2f origin) {
player.setOrigin(origin);
}
sf::Vector2f getOrigin() {
return player.getOrigin();
}
void setRotation(double rotation) {
player.setRotation(rotation);
}
double getRotation() {
return player.getRotation();
}
void setTexture(sf::Texture &texture) {
player.setTexture(&texture);
}
void setTexture(sf::IntRect texture) {
player.setTextureRect(texture);
}
void move(double angle, float velocity) {
rotation = angle;
vec.x = sin(rotation * (3.14 / 180)) * velocity;
vec.y = -cos(rotation * (3.14 / 180)) * velocity;
player.move(vec);
}
void draw(sf::RenderWindow& window) {
window.draw(player);
}
private:
sf::RectangleShape player;
sf::Vector2f vec;
double rotation;
};
