Зацикливается анимация

Зацикливается анимация после отжимания клавиш. Помогите пожалуйста.

C++

#include <SFML/Graphics.hpp> using namespace sf; class Player { public: float x, y, w, h, dx, dy, speed, CurrentFrame; String File; Image image; Texture texture; Sprite sprite; enum { left, right, up, down, downdright, downdleft, updright, updleft, stay } state; Player(String F, int X, int Y, float W, float H) { state = stay; CurrentFrame = 0; dx = 0; dy = 0; y = 0; x = 0; w = W; h = H; x = X; y = Y; File = F; speed = 0; image.loadFromFile("Images/" + File); texture.loadFromImage(image); sprite.setTexture(texture); sprite.setTextureRect(IntRect(0, 0, w, h)); } void control() { if (Keyboard::isKeyPressed(Keyboard::Left)) { state = left; speed = 0.1; } if (Keyboard::isKeyPressed(Keyboard::Right)) { state = right; speed = 0.1; } if (Keyboard::isKeyPressed(Keyboard::Up)) { state = up; speed = 0.1; } if (Keyboard::isKeyPressed(Keyboard::Down)) { state = down; speed = 0.1; } if ((Keyboard::isKeyPressed(Keyboard::Right)) && (Keyboard::isKeyPressed(Keyboard::Down))) { state = downdright; speed = 0.1; } if ((Keyboard::isKeyPressed(Keyboard::Left)) && (Keyboard::isKeyPressed(Keyboard::Down))) { state = downdleft; speed = 0.1; } if ((Keyboard::isKeyPressed(Keyboard::Right)) && (Keyboard::isKeyPressed(Keyboard::Up))) { state = updright; speed = 0.1; } if ((Keyboard::isKeyPressed(Keyboard::Left)) && (Keyboard::isKeyPressed(Keyboard::Up))) { state = updleft; speed = 0.1; } } void animation(float time) { if (state == right) { CurrentFrame += 0.005*time; if (CurrentFrame > 5) CurrentFrame -= 5; sprite.setTextureRect(IntRect(18 * int(CurrentFrame), 84, 18, 28)); } if (state == left) { CurrentFrame += 0.005*time; if (CurrentFrame > 5) CurrentFrame -= 5; sprite.setTextureRect(IntRect(18 * int(CurrentFrame), 56, 18, 28)); } if (state == up) { CurrentFrame += 0.005*time; if (CurrentFrame > 5) CurrentFrame -= 5; sprite.setTextureRect(IntRect(20 * int(CurrentFrame), 28, 20, 28)); } if (state == down) { CurrentFrame += 0.005*time; if (CurrentFrame > 5) CurrentFrame -= 5; sprite.setTextureRect(IntRect(20 * int(CurrentFrame), 0, 20, 28)); } } void update(float time) { animation(time); control(); switch (state) { case right: dx = speed; dy = 0; break; case left: dx = -speed; dy = 0; break; case down: dx = 0; dy = speed; break; case up: dx = 0; dy = -speed; break; case downdright: dx = speed; dy = speed; break; case downdleft: dx = -speed; dy = speed; break; case updright: dx = speed; dy = -speed; break; case updleft: dx = -speed; dy = -speed; break; } x += dx*time; y += dy*time; speed = 0; sprite.setPosition(x, y); } };

попробуй вывести state значение переменной , может оно резко меняется в каком то случае

Нужно добавить что-то вроде

C++

if(Keyboard::isKeyReleased) state = null;

1	if(Keyboard::isKeyReleased) state = null;

В данном случае придётся заменить enum {} state на переменные типа bool
т.к. enum может содержать в себе всего одно состояние, а bool можно включать или выключать по надобности.
