我用LigGdx制作了一个游戏,它看起来像一个RPG游戏。当敌人处于警戒状态时,它必须跟随玩家,但它只能向前、向后、向左、向右移动,当敌人相撞时也必须转移目标,寻找到达玩家的最佳途径,我是游戏开发的新手,我的算法可能完全错误,所以,我真的需要帮助……
private void enemyInAlert(Enemy enemy, float delta) {
detectDirection(enemy);
enemyWalking(enemy, delta);
if (Math.round(getDistanceXofLastPosition(enemy)) == 0 && Math.round(getDistanceYofLastPosition(enemy)) == 0) {
enemy.setState(States.IDLE);
lastPosition = null;
}
}
private void detectDirection(Enemy enemy) {
float diff = getDistanceXofLastPosition(enemy) - getDistanceYofLastPosition(enemy);
if (diff < 0) {
getDirectionX(enemy);
} else if (diff > 0) {
getDirectionY(enemy);
}
}
private void getDirectionY(Enemy enemy) {
int enemyY = Math.round(enemy.getY());
int lastPositionY = Math.round(lastPosition.getY());
if (enemyY < lastPositionY && enemy.isDirectionBlocked(Direction.FORWARD) == false) { //Enemy needs to go forward
enemy.setDirection(Direction.FORWARD);
enemy.blockDirection(Direction.BACKWARD);
} else if (enemyY > lastPositionY && enemy.isDirectionBlocked(Direction.FORWARD) == false) { //Enemy needs to go backward
enemy.setDirection(Direction.BACKWARD);
enemy.blockDirection(Direction.FORWARD);
} else { //Enemy needs to change direction
if (enemy.isDirectionBlocked(Direction.LEFT) == false || enemy.isDirectionBlocked(Direction.LEFT) == false) {
enemy.blockDirection(Direction.BACKWARD);
enemy.blockDirection(Direction.FORWARD);
getDirectionX(enemy);
} else {
sortRandomDirection(enemy);
}
}
}
private void getDirectionX(Enemy enemy) {
int enemyX = Math.round(enemy.getX());
int lastPositionX = Math.round(lastPosition.getX());
if (enemyX < lastPositionX && enemy.isDirectionBlocked(Direction.RIGHT) == false) { //Enemy needs to go right
enemy.setDirection(Direction.RIGHT);
enemy.blockDirection(Direction.LEFT);
} else if (enemyX > lastPositionX && enemy.isDirectionBlocked(Direction.LEFT) == false) {
enemy.setDirection(Direction.LEFT);
enemy.blockDirection(Direction.RIGHT);
} else { //Enemy needs to change direction
if (enemy.isDirectionBlocked(Direction.FORWARD) == false && enemy.isDirectionBlocked(Direction.BACKWARD) == false) {
enemy.blockDirection(Direction.LEFT);
enemy.blockDirection(Direction.RIGHT);
getDirectionY(enemy);
} else {
sortRandomDirection(enemy);
}
}
}我接受建议,我可以改变所有的代码,没有怜悯.对不起,英语不好。
谢谢!!
编辑:现在,我正在尝试使用A*,或者类似的东西。D.我的代码:
private void calculateRoute(Enemy enemy) {
int lowerPath = getDistanceXofLastPosition(enemy.getBounds()) + getDistanceYofLastPosition(enemy.getBounds());
path = new ArrayList<Rectangle>();
Rectangle finalRect = new Rectangle(enemy.getBounds());
List<Rectangle> openList = new ArrayList<Rectangle>();
while (getDistanceXofLastPosition(finalRect) > 0 || getDistanceYofLastPosition(finalRect) > 0) {
for (int i = -1; i < 2; i+= 1) {
outerloop:
for (int j = -1; j < 2; j+= 1) {
Rectangle temp = new Rectangle(finalRect);
temp.offSet(i, j);
if (openList.contains(temp)) {
continue;
}
if ((i == -1 && j == -1) || (i == 1 && j == -1) || (i == 0 && j == 0) || (i == 1 && j == -1) || (i == 1 && j == 1)) {
continue;
}
for (Collider collider : colliders) {
if (collider.isSolid() && Utils.detectCollision(temp, collider.getBounds())) {
continue outerloop;
}
}
openList.add(temp);
}
}
int lowerDistance = Integer.MAX_VALUE;
for (Rectangle rect : openList) {
int distance = getDistanceXofLastPosition(rect) + getDistanceYofLastPosition(rect);
distance = distance + lowerPath;
if (distance < lowerDistance) {
lowerDistance = distance;
finalRect = rect;
}
}
path.add(new Rectangle(finalRect));
}
}但是是不是很慢,我能做些什么来提高业绩呢?

您可能需要查看*。
您可以很容易地将您的地图转换成一个图,使用每个瓷砖作为顶点,并将顶点与与其接近的所有其他顶点连接起来。与边缘相关的成本可能是可变的,例如,在河流上移动I瓦可能比在平面上移动一个瓷砖花费更多。
然后可以使用路径搜索算法从一个点到另一个点找到最佳路径。使用此算法将有两个缺点:
如果计算和存储成本确实存在问题,您可以求助于A*的表亲之一,例如
