我最近开始学习SFML,我想作一个傍克隆,因为它应该是容易的,但我得到了这个问题,而编码:SFML屏幕移动速度很慢
蝙蝠运动是非常laggy,当我请按A或D它移动一下然后停止然后再次移动并继续。
#include <SFML/Graphics.hpp>
#include "bat.h"
int main()
{
int windowWidth=1024;
int windowHeight=728;
sf::RenderWindow window(sf::VideoMode(windowWidth, windowHeight), "SFML window");
bat Bat(windowWidth/2,windowHeight-20);
while (window.isOpen())
{
sf::Event event;
while (window.pollEvent(event))
{
if(sf::Keyboard::isKeyPressed(sf::Keyboard::A))
Bat.batMoveLeft();
else if(sf::Keyboard::isKeyPressed(sf::Keyboard::D))
Bat.batMoveRight();
else if (event.type == sf::Event::Closed)
window.close();
}
window.clear();
Bat.batUpdate();
window.draw(Bat.getShape());
window.display();
}
return 0;
}
bat.h
#ifndef BAT_H
#define BAT_H
#include <SFML/Graphics.hpp>
class bat
{
private:
sf::Vector2f position;
float batSpeed = .3f;
sf::RectangleShape batShape;
public:
bat(float startX, float startY);
sf::FloatRect getPosition();
sf::RectangleShape getShape();
void batMoveLeft();
void batMoveRight();
void batUpdate();
};
#endif // BAT_H
bat.cpp
#include "bat.h"
using namespace sf;
bat::bat(float startX,float startY)
{
position.x=startX;
position.y=startY;
batShape.setSize(sf::Vector2f(50,5));
batShape.setPosition(position);
}
FloatRect bat::getPosition()
{
return batShape.getGlobalBounds();
}
RectangleShape bat::getShape()
{
return batShape;
}
void bat::batMoveLeft()
{
position.x -= batSpeed;
}
void bat::batMoveRight()
{
position.x += batSpeed;
}
void bat::batUpdate()
{
batShape.setPosition(position);
}
感谢的人我它! –
