Я реализовал аналогичную функцию NGUI, вы можете внести некоторые изменения, если используете UGUI.Идея заключается в установке nextInput вручную с помощью общедоступной переменной
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class UIInputTab : MonoBehaviour {
UIInput thisInput;
public GameObject nextInput;
void Start () {
thisInput = transform.GetComponent<UIInput>();
}
void Update () {
if (thisInput.isSelected)
{
if (nextInput != null && Input.GetKeyDown(KeyCode.Tab))
{
UICamera.selectedObject = nextInput;
}
}
}
}
Update
: динамически генерировать случайное число InputField и назначать следующий InputField.
InputfieldTest.cs
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.EventSystems;
public class InputfieldTest : MonoBehaviour {
public GameObject inputFieldPrefab;
public GameObject panel;
private GameObject lastInput;
EventSystem m_EventSystem;
void Start () {
m_EventSystem = EventSystem.current;
for(int i = 0; i < Random.Range(5,10);i++){
GameObject column = new GameObject();
column.transform.parent = panel.transform;
column.name = "Column" + i;
for (int j = 0; j < Random.Range(2, 8);j++){
GameObject input = Instantiate(inputFieldPrefab);
input.transform.parent = column.transform;
input.GetComponent<RectTransform>().position = new Vector3(300+ 200 * j, 300+ 200 * i, 0);
input.name = "InputField" + i + "-" + j;
// set nextInput
if(lastInput != null) {
lastInput.GetComponent<InputTabControl>().nextInput = input;
}
lastInput = input;
}
}
}
void Update () {
GameObject currentSelect = m_EventSystem.currentSelectedGameObject;
if (currentSelect != null)
{
print(currentSelect.name);
GameObject nextInput = currentSelect.GetComponent<InputTabControl>().nextInput;
if (nextInput != null && Input.GetKeyDown(KeyCode.Tab))
{
InputField inputfield = nextInput.GetComponent<InputField>();
if (inputfield != null)
{
inputfield.OnPointerClick(new PointerEventData(m_EventSystem));
m_EventSystem.SetSelectedGameObject(nextInput.gameObject, new BaseEventData(m_EventSystem));
}
}
}
}
}
InputTabControl.cs
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class InputTabControl : MonoBehaviour {
public GameObject nextInput;
}
