Pacman在C++和SFML中的碰撞代碼幫助

Question

因此，最近我開始在C++和SFML中製作Pacman克隆。一切都很順利開發遊戲，直到我需要創建牆壁碰撞。碰撞時我不太好，所以我期待着有問題。

我想要做的是檢查牆壁是否高於你，除了你或其他什麼，然後停止玩家，如果你碰撞牆。

問題是，當你撞上一堵牆時，你就會停下來提前。有時候你會陷入其中。這不會與代碼相混淆，因爲Pacman無法在牆壁超過你或某物時轉身，但當跑到牆壁停下來的時候。

這裏是我剛纔提到的關於轉碰撞的代碼（它也適用，因此無需用於固定）：

// All of the movement functions. 
if (Keyboard::isKeyPressed(Keyboard::Up) && mapData[xtile + (ytile - 1) * 25] != 1 && mapData[xtile + (ytile - 1) * 25] != 2){ 
    direction = Directions{ Up }; 
    setVelocity(0.0, -2.5); 
    source.x = 73; 
} 
if (Keyboard::isKeyPressed(Keyboard::Down) && mapData[xtile + (ytile + 1) * 25] != 1 && mapData[xtile + (ytile + 1) * 25] != 2){ 
    direction = Directions{ Down }; 
    setVelocity(0.0, 2.5); 
    source.x = 110; 
} 
if (Keyboard::isKeyPressed(Keyboard::Left) && mapData[(xtile + 1) + ytile * 25] != 1 && mapData[(xtile - 1) + ytile * 25] != 2){ 
    direction = Directions{ Left }; 
    setVelocity(-2.5, 0.0); 
    source.x = 0; 
} 
if (Keyboard::isKeyPressed(Keyboard::Right) && mapData[(xtile - 1) + ytile * 25] != 1 && mapData[(xtile + 1) + ytile * 25] != 2){ 
    direction = Directions{ Right }; 
    setVelocity(2.5, 0.0); 
    source.x = 38; 
} 

的source.x啄是動畫，讓無關面臨着問題。 setVelocity設置玩家的速度，方向就是玩家的方向。方向由enumuration設定。

這裏是我的代碼，如果你想看到所有其他的文件和類（儘管它們可能與問題無關）或其他信息，只要問我代碼或解釋，我會發布它！

但是enough呀，我們走吧！

你去那裏。如果您對如何解決或解決此問題有任何建議，請隨時將其發佈給我。請記住，如果您需要更多信息，請問我。提前致謝！

如何移動這兩條線：

pacman.update(mapData, maze.map); 
pacman.sprite.move(pacman.xvel, pacman.yvel); // Move Pacman 

在這之後的檢查：

if (pacman.direction == Right ... 

看來你更新1日再檢查。
