Question

'我正在制作一个简单的游戏，对于其中的一部分，我希望那里有敌人的攻击你。首先，我需要让它们移动在这段代码中，“敌人”只是一个球。我正在使用一个名为“mob1”的对象作为球的位置，以便稍后我可以有多个。

（顺便说一下，我正在使用Slick-只是改变任何东西）

我的游戏状态 -

我的暴徒课 -

 package Main;

import org.newdawn.slick.Graphics;

public class SimpleMob {

    //This class shall be used as an object creator. This will randomly move a graphic around, near to a player
    private float MobX;
    private float MobY;
    private int AmountMoved = 0;
    private boolean MoveRight = true;
    private boolean MoveLeft;
    private boolean PlayerNear = false;
    public boolean PlayerDetected = false;

    //Used to find the mobs X
    public float getX(){
        return MobX;
    }

    //Used to find the mobs Y
    public float getY(){
        return MobY;
    }

    //Used to set the mobs X
    public void setX(float X){
        MobX = X;
    }   

    //Used to set the mobs Y
    public void setY(float Y){
        MobY = Y;
    }

    //Used to simply move the mob on its X co-ords
    public void moveX(int delta){
        MobX += delta*0.1f;
    }

    //Used to simply move the mob on its Y co-ords
    public void moveY(int delta){
        MobY += delta*0.1f;
    }

    public void autoEveryThing(int delta, float playerX, float playerY) {

        System.out.println(AmountMoved);
        // If the player has not been spotted the NPC/Mob will move left and
        // right by 100 Pixels.
        if (MoveRight == true) {
            AmountMoved++;
            MobX += delta * 0.1f;
            if (AmountMoved == 100) {
                MoveRight = false;
                MoveLeft = true;
                AmountMoved = 0;
            }
        }
        if (MoveLeft == true) {
            MobX -= delta * 0.1f;
            AmountMoved++;
            if (AmountMoved == 100) {
                MoveRight = true;
                MoveLeft = false;
                AmountMoved = 0;
            }
        }
    }

}

任何有关这方面的帮助都会很好，（或者如果有更正确/更容易的方式来制造小怪）

Answer 1

问题可能是System.out.println(...)中的autoEveryThing(...)来电。这是每秒做很多次，输出到控制台是人们可以做的最密集的事情之一。

出于某种原因，移动球是非常摇摇欲坠的？
