Question by unity_BFzrl_qdvjgzCw · Nov 28, 2018 at 06:14 PM · colliderscript.ontriggerenterfadein

Make an object fade in/fade out

Is it possible to make this script work the other way around? Basically I need to make an object appear as I enter the collider and disappear as i leave it. cant figure it out. thank you

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

public class RoofHouse : MonoBehaviour {

 public GameObject Roof = null;


 void OnTriggerEnter(Collider collider)

 {

     if(IsCharacter(collider))

     {

         SetMaterialTransparent();

         iTween.FadeTo(Roof, 0, 1);

     }

 }


 private bool IsCharacter(Collider collider)

 {

   // Implement you logic here if it is your player that is the collider

   return true;

 }


 private void SetMaterialTransparent()

 {

     foreach (Material m in Roof.GetComponent<Renderer>().materials)

     {

         m.SetFloat("_Mode", 2);

         m.SetInt("_SrcBlend", (int)UnityEngine.Rendering.BlendMode.SrcAlpha);

         m.SetInt("_DstBlend", (int)UnityEngine.Rendering.BlendMode.OneMinusSrcAlpha);

         m.SetInt("_ZWrite", 0);

         m.DisableKeyword("_ALPHATEST_ON");

         m.EnableKeyword("_ALPHABLEND_ON");

         m.DisableKeyword("_ALPHAPREMULTIPLY_ON");

         m.renderQueue = 3000;

     }

 }


 private void SetMaterialOpaque()

 {

     foreach (Material m in Roof.GetComponent<Renderer>().materials)

     {

         m.SetInt("_SrcBlend", (int)UnityEngine.Rendering.BlendMode.One);

         m.SetInt("_DstBlend", (int)UnityEngine.Rendering.BlendMode.Zero);

         m.SetInt("_ZWrite", 1);

         m.DisableKeyword("_ALPHATEST_ON");

         m.DisableKeyword("_ALPHABLEND_ON");

         m.DisableKeyword("_ALPHAPREMULTIPLY_ON");

         m.renderQueue = -1;

     }

 }


 void OnTriggerExit(Collider collider)

 {

     if (IsCharacter(collider))

     {

         // Set material to opaque

         iTween.FadeTo(Roof, 1, 1);


         Invoke("SetMaterialOpaque", 1.0f);

     }

 }

}
