單擊時讓玩家移動到我的鼠標？

Question

如何讓我的玩家在被點擊時移動到鼠標上（如在魔獸中）？

到目前爲止，我曾嘗試：

if (Mouse.isButtonDown(0)) { 

    if (X < Mouse.getX()) { 
     X += Speed; 
    } 
    if (X > Mouse.getX()) { 
     X -= Speed; 
    } 
    if (Y < Mouse.getY()) { 
     Y += Speed; 
    } 
    if (Y > Mouse.getY()) { 
     Y -= Speed; 
    } 
} 

但這只不過是我想要做什麼，如果我按住鼠標。

只需存儲最後一次點擊的位置並讓玩家在該方向上移動即可。

添加這些字段，以您的播放器類：

int targetX; 
int targetY; 

在您的更新方法存儲新的目標和適用的運動：

// A new target is selected 
if (Mouse.isButtonDown(0)) { 

    targetX = Mouse.getX(); 
    targetY = Mouse.getY(); 
} 

// Player is not standing on the target 
if (targetX != X || targetY != Y) { 

    // Get the vector between the player and the target 
    int pathX = targetX - X; 
    int pathY = targetY - Y; 

    // Calculate the unit vector of the path 
    double distance = Math.sqrt(pathX * pathX + pathY * pathY); 
    double directionX = pathX/distance; 
    double directionY = pathY/distance; 

    // Calculate the actual walk amount 
    double movementX = directionX * speed; 
    double movementY = directionY * speed; 

    // Move the player 
    X = (int)movementX; 
    Y = (int)movementY; 
}
