从库存拖到2dtexture到游戏 [英] Drag 2dtexture from inventory to game

问题描述

还好吧，所以我想提出一个移动2D建设游戏。 。在那里你可以在游戏中你的库存拖动矩形或圆形

Allright, so I am making a mobile 2d building game. where you can drag a rectangle or circle from your inventory in the game.

我怎么想它被设置：
顶部或右侧与对象/纹理库存，当我拖动一个项目从我的库存进入游戏。它然后删除清单中的项目。这些物品清点后都将移动1插槽了。从而使第一插槽占用百达

how I would like it to be set up: on the top or right side is an inventory with objects/textures, when I drag one of the items from my inventory into the game. it then removes the item from the inventory. after that the items inventory will all move 1 slot up. so that the first slot is allways occupied.

我将如何使这项工作？有人可以请帮我想想还是给我一些例子吗？

How would I make this work? can someone please help me think or give me some examples?

在此先感谢！

推荐答案

首先，你需要画一个图像清单中的项目。
我已经与连接到它的图像的图形用户界面按钮这样做过。
这是在C＃中的例子：

First you need to draw an image for the item in the inventory. I have done this before with an GUI Button with an image attached to it. Here is an example in C#:

void OnGUI(){
    if (GUI.Button(new Rect(0, 0 , 10, 10), itemTexture,))
    {
    //The if here is to get when the image get pushed.
    //Push the item to the world
    }
}

当玩家点击该项目必须将它推向世界。
你可以做到这一点与这个代码：

When the player clicks on the item you must push it to the world. You can do that with this code:

private Vector3 mousePositionInWorld = Camera.main.ScreenToWorldPoint(Input.mousePosition);
private Object block = Instantiate(objectYouClicked, new Vector3(mousePositionInWorld.x, mousePositionInWorld.y, 0), Quaternion.identity);

的对象必须被绑定到播放机鼠标/触摸位置。
你可以绑定到该代码玩家的对象：

The object must be bound to the player mouse/touch position. You can make the object bound to the player with this code:

private Vector3 screenPoint;
void OnMouseDown()
{
    screenPoint = Camera.main.WorldToScreenPoint(gameObject.transform.position);
}

void OnMouseDrag()
{
      Vector3 currentScreenPoint = new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPoint.z);
      Vector3 currentPos = Camera.main.ScreenToWorldPoint(currentScreenPoint);
      rigidbody.MovePosition(currentPos);
}

因此，例如你有一个清单对象。像这样的：

So for example you have an inventory object. Like this:

void OnGUI(){
    if (GUI.Button(new Rect(0, 0 , 10, 10), itemTexture,))
    {
        private Vector3 mousePositionInWorld = Camera.main.ScreenToWorldPoint(Input.mousePosition);
        private Object block = Instantiate(objectYouClicked, new Vector3(mousePositionInWorld.x, mousePositionInWorld.y, 0), Quaternion.identity);
    }
}

然后你有一个脚本的预制/对象连接包含此代码：

Then you have an prefab/object with an script attached that contains this code:

private Vector3 screenPoint;
void OnMouseDown()
{
    screenPoint = Camera.main.WorldToScreenPoint(gameObject.transform.position);
}

void OnMouseDrag()
{
      Vector3 currentScreenPoint = new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPoint.z);
      Vector3 currentPos = Camera.main.ScreenToWorldPoint(currentScreenPoint);
      rigidbody.MovePosition(currentPos);
}

当玩家点击并保持该物体的位置在mousebutton这样改变到mouseposition

This way when the player clicks and holds the mousebutton on the object the position is changed to the mouseposition.
