您好我正在制作类似于塞尔达传说的角色扮演游戏。我的游戏中有一个功能,当玩家用剑攻击敌人时,敌人会被击退n个单位。我有一个碰撞检测,有时按预期工作,有时敌人穿过墙壁并卡在另一边,然后敌人可以简单地穿过墙壁。如果可能的话,让敌人在与墙碰撞时向玩家移动将是我相信这个问题的一种可能的解决方案,但我不知道如何实现这一点。这是我目前的碰撞代码:
// Enemy Collides with Wall
counter1 = 0;
for (iter4 = enemyArray.begin(); iter4 != enemyArray.end(); iter4++)
{
counter2 = 0;
for (iter15 = wallArray.begin(); iter15 != wallArray.end(); iter15++)
{
if (enemyArray[counter1].rect.getGlobalBounds().intersects(wallArray[counter2].rect.getGlobalBounds()))
{
enemyArray[counter1].isCollided = true;
//Hit Wall
if ((enemyArray[counter1].direction == 1 || enemyArray[counter1].rect.getPosition().y >= wallArray[counter2].rect.getPosition().y)) //up
{
enemyArray[counter1].canMoveUp = false;
enemyArray[counter1].canMoveLeft = false;
enemyArray[counter1].canMoveRight = false;
enemyArray[counter1].rect.move(0, 7);
}
else if ((enemyArray[counter1].direction == 2 || enemyArray[counter1].rect.getPosition().y <= wallArray[counter2].rect.getPosition().y)) //Down
{
enemyArray[counter1].canMoveDown = false;
enemyArray[counter1].canMoveRight = false;
enemyArray[counter1].canMoveLeft = false;
enemyArray[counter1].rect.move(0, -7);
}
else if ((enemyArray[counter1].direction == 3 || enemyArray[counter1].rect.getPosition().x >= wallArray[counter2].rect.getPosition().x)) //Left
{
enemyArray[counter1].canMoveLeft = false;
enemyArray[counter1].canMoveUp = false;
enemyArray[counter1].canMoveDown = false;
enemyArray[counter1].rect.move(7, 0);
}
else if ((enemyArray[counter1].direction == 4 || enemyArray[counter1].rect.getPosition().x <= wallArray[counter2].rect.getPosition().x)) //Right
{
enemyArray[counter1].canMoveRight = false;
enemyArray[counter1].canMoveUp = false;
enemyArray[counter1].canMoveDown = false;
enemyArray[counter1].rect.move(-7, 0);
}
}
counter2++;
}
counter1++;
}
//Knock Back enemy away from sword && sword2
counterKnockBack++;
counter2 = 0;
for (iter4 = enemyArray.begin(); iter4 != enemyArray.end(); iter4++)
{
if (enemyArray[counter2].knockback == true)
{
if (enemyArray[counter2].isCollided == false)
{
if ((Player1.rect.getPosition().y > enemyArray[counter2].rect.getPosition().y))
{
enemyArray[counter2].rect.move(0, -3); //up
}
else if ((Player1.rect.getPosition().y < enemyArray[counter2].rect.getPosition().y))
{
enemyArray[counter2].rect.move(0, 3); //down
}
if ((Player1.rect.getPosition().x > enemyArray[counter2].rect.getPosition().x))
{
enemyArray[counter2].rect.move(-3, 0); //left
}
else if ((Player1.rect.getPosition().x < enemyArray[counter2].rect.getPosition().x))
{
enemyArray[counter2].rect.move(3, 0); //right
}
if (counterKnockBack >= 20)
{
enemyArray[counter2].knockback = false;
}
}
}
counter2++;
}
//turn off collided counter
counterCollided++;
counter2 = 0;
for (iter4 = enemyArray.begin(); iter4 != enemyArray.end(); iter4++)
{
if (enemyArray[counter2].isCollided == true)
{
if (counterCollided >= 30)
enemyArray[counter2].isCollided = false;
}
counter2++;
}
我不知道为什么敌人有时可以简单地穿过墙壁而不被撞倒。那我怎么能解决这个问题呢?
