在随机路径上将对象移动到另一个对象 [英] Moving an object to another on a random path

问题描述

我有一个程序，它在开始时创建多个随机放置的对象(球)，现在我试图将玩家球自动移向最近的对象，直到它们的中心相同.我已经确定了存储在一个名为 distance 且索引为closest"的数组中的最近对象的距离，并将速度设置为在其他地方初始化的变量 delta，我如何获得正确的方向?马上它只是对角移动，但不向最近的球移动

I have a program which creates multiple randomly placed objects(balls) at the beginning, now im trying to move the player ball towards the closest object automatically until their centres are the same. I have determined the distance of the closest object stored in an array called distance with index of 'closest', and set the speed as variable delta initialised somewhere else, how do i get the direction right? Right now It moves just diagonally but not towards the closest ball

coordinatex[closest] 和coordinatey[closest] 是最近对象的 x 和 y 坐标.

coordinatex[closest] and coordinatey[closest] are the x and y coordinates of the closest object.

playerObject.getX 和 playerObjectgetY 给我玩家注射的坐标

playerObject.getX and playerObjectgetY gives me the coordinates of the player onject

public void move(int delta) {
     for(int i=0; i<distance[closest]; i++) {
        if (x<coordinatex[closest] && y<coordinatey[closest]) {     
            playerObject.setX(playerObject.getX() + 0.1*delta);     
            playerObject.setY(playerObject.getY() + 0.1*delta);    
        } else if(x>coordinatex[closest] && y>coordinatey[closest]) {     
            playerObject.setX(playerObject.getX() - 0.1*delta);     
            playerObject.setY(playerObject.getY() - 0.1*delta);    
        } else if(x>coordinatex[closest] && y<coordinatey[closest]) {     
            playerObject.setX(playerObject.getX() - 0.1*delta);     
            playerObject.setY(playerObject.getY() + 0.1*delta);    
        } else if (x<coordinatex[closest] && y>coordinatey[closest]) {     
            playerObject.setX(playerObject.getX() + 0.1*delta);     
            playerObject.setY(playerObject.getY() - 0.1*delta);         
        } 
    }
}

推荐答案

我看到了你的四个半基本(对角线)方向的处理程序，但没有四个基本方向.例如，在这个游戏中，敌人使用move(int row, int col) 方法，显示 这里，从八个方向中的任何一个.

I see your handlers for the four semi-cardinal (diagonal) directions, but not the four cardinal directions. In this game, for example, enemies approach the player in a step-wise manner using the move(int row, int col) method, shown here, from any of eight directions.
