随时间随机移动角色 [英] Move a character randomly with time

问题描述

我正在尝试使用libgdx做游戏，例如缓存游戏"

I'm trying to do a game with libgdx like "Cache-cache game"

我希望我的角色首先停留 2 秒，并每 2 秒给一个新的随机位置，即数组 carte 的一个新元素.

I want for my character to stay 2 seconds in the first place and to give each 2 seconds a new Random place, i.e a new element of the array carte.

首先，我生成了我的随机索引，并且角色停留在首位.

First, I have generate my random index and the character stay in the first place.

我的问题是:如何使每个键盘输入都使我的角色在数组中的随机位置移动?

My problem is : How should I make that each keyboard input makes my character move in a random place in the array?

这是我的代码:

大家好，我正在尝试使用libgdx做游戏，例如缓存游戏"我想让我的角色在第一时间停留2秒，并为每2秒分配一个新的array("carte")随机位置*首先我已经生成了我的随机索引，并且角色停留在首位.但我的问题是::与每个键盘输入相比，我应该如何使字符在数组中的随机位置移动

hi everybody i'm trying to do a game with libgdx like "Cache-cache game" i want for my character staying 2 second in the first place and to give each 2seconde a new Random place of the array("carte") *first i have generate my random index and the character stay in the first place . but my problem is :: how i should making for than each keybord input my character moving in a random place in the array

任何想法！！！这是我的代码:::

any idea!!! this is my code:::

推荐答案

所以，您想保留位置随时间变化的随机变化，还希望通过键盘输入添加变化，对吧?！

so, you want to keep the the random changes of the position by time and also add a change by keyboard inpput , right?!

尝试:

counterTime += Gdx.graphics.getDeltaTime();
time += delta;
if(counterTime > 2f ) {// each second ==> one call to position random

    position = new Vector2(this.mari.x, this.mari.y);
    counterTime =0f;


}else { // between 2 seconds
    if(Gdx.input.isKeyPressed(Keys.B)) { // if "B" of Keyboard is pressed
        counterTime =3f; // go directly to the next random position

    }
}
