Unity 3D – Use scripts with Unity editor .

You need to have Unity versions 2018.2b or 2017.4: You need to create a default project and add a new C# script. The script I used is named EditorWindowTest. This is the source code of this script:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
// you need to add the UnityEditor
using UnityEditor;

public class EditorWindowTest : EditorWindow {
    // massage to show 
    private const string help_nameobj = "Enter the name of object to observe!";
    // zero point for vector position 
    private Vector3 location = Vector3.zero;
    // var name for my object 
    private string observedName = "";
    // add menu Tool - Test_Editor
    [MenuItem("Tools/Test_Editor")]
    // Use this for initialization
    public static void CreateMyEditorCode()
    {
    // create editor window
        EditorWindow.GetWindow<EditorWindowTest>();
}

    public void OnGUI()
    {
   // this part will use a 
        observedName = EditorGUILayout.TextField("Name", observedName);
        // find object 
        GameObject foundObject = GameObject.Find(observedName);
        // if foundObject get location 
        if (foundObject)
        {
            foundObject.transform.position = EditorGUILayout.Vector3Field("Location", foundObject.transform.position);
        } else {
            // show a message 
            EditorGUILayout.HelpBox(help_nameobj, MessageType.Info);
        }
        // use location into window editor
        location = EditorGUILayout.Vector3Field("Location", location);
        // test the button 
        if (GUILayout.Button("Show debug log text"))
        {
            // show into debug the text: Worked 
            Debug.Log("Worked!");
        }
    }
}

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

// you need to add the UnityEditor

using UnityEditor;

public class EditorWindowTest : EditorWindow {

// massage to show

private const string help_nameobj = "Enter the name of object to observe!";

// zero point for vector position

private Vector3 location = Vector3.zero;

// var name for my object

private string observedName = "";

// add menu Tool - Test_Editor

[MenuItem("Tools/Test_Editor")]

// Use this for initialization

public static void CreateMyEditorCode()

{

// create editor window

EditorWindow.GetWindow<EditorWindowTest>();

}

public void OnGUI()

{

// this part will use a

observedName = EditorGUILayout.TextField("Name", observedName);

// find object

GameObject foundObject = GameObject.Find(observedName);

// if foundObject get location

if (foundObject)

{

foundObject.transform.position = EditorGUILayout.Vector3Field("Location", foundObject.transform.position);

} else {

// show a message

EditorGUILayout.HelpBox(help_nameobj, MessageType.Info);

}

// use location into window editor

location = EditorGUILayout.Vector3Field("Location", location);

// test the button

if (GUILayout.Button("Show debug log text"))

{

// show into debug the text: Worked

Debug.Log("Worked!");

}

Unity 3D – using the gyroscope.

If your tablet, phone or laptop has a gyroscope device then you can used with Unity 3D game engine. Create your project and use this C# script to test and show info about your gyroscope device.

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class GyroDevice : MonoBehaviour {
    private bool gyroEnable;
    private Gyroscope gyro;

	// Use this for initialization
	void Start () {
        // enable the gyroscope
        gyroEnable = EnableGyro();
		
	}

    private bool EnableGyro()
    {
        // test the gyroscope
        if (SystemInfo.supportsGyroscope)
        {
            gyro = Input.gyro;
            gyro.enabled = true;

            return true;
        }
        return false;
    }

    // Update is called once per frame
    void Update () {
        if (gyroEnable)
        {
            // show info from gyroscope 
            Debug.Log("attitude "+gyro.attitude);
            Debug.Log("gravity " + gyro.gravity);
            Debug.Log("userAcceleration " + gyro.userAcceleration);
        }
	}
}

using System;

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

public class GyroDevice : MonoBehaviour {

private bool gyroEnable;

private Gyroscope gyro;

// Use this for initialization

void Start () {

// enable the gyroscope

}

private bool EnableGyro()

{

{

gyro = Input.gyro;

gyro.enabled = true;

return true;

}

return false;

}

// Update is called once per frame

void Update () {

if (gyroEnable)

{

// show info from gyroscope

Debug.Log("attitude "+gyro.attitude);

Debug.Log("gravity " + gyro.gravity);

Debug.Log("userAcceleration " + gyro.userAcceleration);
