Unity3d 通过代码手动创建button（不用GUI自带的button以及其他插件）
using Liulala.Utils;
using UnityEngine;
public class Button : MonoBehaviour
{
protected virtual void OnMoveOver()
{
}
protected virtual void OnMoveOut()
{
}
protected virtual void OnPressDown()
{
}
protected virtual void OnPressUp()
{
}
protected bool IsButtonPressed { get { return _isButtonPressed; } }
protected bool IsButtonHovered { get { return _isButtonHovered; } }
protected virtual void Awake()
{
if (_buttonCollider == null)
{
_buttonCollider = GetComponent<Collider>();
if (_buttonCollider == null)
{
_buttonCollider = GetComponentInChildren<Collider>();
if (_buttonCollider)
{
Debug.LogError("Couldn't find a collider for button");
}
}
}
}
protected virtual void Update()
{
if (HitButtonArea())
{
_isButtonHovered = true;
if (!PlatformUtil.IsTouchDevice)
{
OnMoveOver();
}
if (GameControl.Input.IsClickDown)
{
_isButtonPressed = true;
OnPressDown();
}
else if (GameControl.Input.IsClickUp && _isButtonPressed)
{
_isButtonPressed = false;
OnPressUp();
}
}
else if (_isButtonHovered)
{
_isButtonHovered = false;
OnMoveOut();
}
}
private bool HitButtonArea()
{
if (GameControl.Input.HasTouch)
{
Ray ray = Camera.main.ScreenPointToRay(GameControl.Input.MousePosition);
RaycastHit hit;
if (Physics.Raycast(ray, out hit, float.PositiveInfinity, ~LayerMask.NameToLayer("UI")))
{
return hit.collider == _buttonCollider;
}
}
return false;
}
[SerializeField]
private Collider _buttonCollider;
private bool _isButtonHovered;
private bool _isButtonPressed;
}
其他脚本继承于button脚本。
using UnityEngine;
using System.Collections;
public class StartButton : Button
{
protected override void Awake()
{
base.Awake();
_quadMesh = GetComponent<QuadMesh>();
}
protected override void OnMoveOut()
{
_quadMesh.Texture = _normalTexture;
}
protected override void OnPressDown()
{
_quadMesh.Texture = _activeTexture;
}
protected override void OnPressUp()
{
_quadMesh.Texture = _normalTexture;
Application.LoadLevel("Main");
}
[SerializeField]
private Texture2D _normalTexture;
[SerializeField]
private Texture2D _activeTexture;
private QuadMesh _quadMesh;
}
补充：综合编程 , 其他综合 ,
