java - 将位置移向目标位置

Question

我有两个位置（纬度、经度），一个是当前位置，另一个是目标。我想做的是有一个循环，将当前位置分阶段移动到目标位置。我不完全确定将当前位置转移到目标位置的数学方法。

Answer 1

这是在两点之间分阶段实现所有点的粗略演示代码。希望对您有所帮助：

import java.awt.Point;
public class  Path
{
    public static void main(String[] args) 
    {
        Point start         = new Point(0,0);
        Point destination   = new Point(100,150);
        int   iStages = 9;//Suppose I want to reach to destination in 9 jumps
        int   jumpX = (destination.x - start.x) / iStages;
        int   jumpY = (destination.y - start.y) / iStages;
        Point currPos = start;
        for (int i = 0; i < iStages ; i++)
        {
            System.out.println(currPos);
            currPos = new Point(currPos.x + jumpX , currPos.y + jumpY );
        }
        currPos = new Point(destination.x , destination.y);
        System.out.println(currPos);
    }
}
