I am working on a unity project , where I apply a texture on a sphere game object . I get a the texture from a .jpg file. It is specified that the .jpg file isn't placed in Resources or Assets folder , but on a folder inside the project , where the .exe of the project would be also , after building it . So the path for the .jpg is /project-name/Build/texture.jpg . In order to access the .jpg , I use the UnityWebRequestTexture class , which is modified for accessing files on the disk , using also a relative path , as you can see on my code .
// For accessing the .jpg and using it as file we use the UnityWebRequestTexture.GetTexture (see uinty docs)
// The path is a URL , but we modify it to work for local computer with relative path
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Networking;
public class LoadTexture : MonoBehaviour
{
Texture2D texture;
Texture2D texture2;
public GameObject sph;
bool on = false;
public Renderer sphRenderer;
void Start()
{
sphRenderer = sph.GetComponent<Renderer>();
StartCoroutine(GetText());
IEnumerator GetText()
{
using (UnityWebRequest uwr = UnityWebRequestTexture.GetTexture("file://" + "/../Build/texture-sphere.jpg")) // Relative path
{
yield return uwr.SendWebRequest();
if (uwr.isNetworkError || uwr.isHttpError)
{
// Display error
Debug.Log(uwr.error);
}
else
{
// Get downloaded asset bundle
texture = DownloadHandlerTexture.GetContent(uwr);
}
}
}
}
void Update()
{
// Implemenation of toggle by pressing T key
// Press T
if (Input.GetKeyDown(KeyCode.T))
on = !on;
if (on)
{
// Change to white color first
sphRenderer.material.color = Color.white;
//Resources.Load("texture", typeof(Texture2D));
// Set the Texture to the SPH Renderer
sphRenderer.material.mainTexture = texture as Texture2D;
}
else if (!on)
{
//set texture to null
sphRenderer.material.mainTexture = null;
// change color to red
sphRenderer.material.color = Color.red;
}
}
}
Essentially what I'm doing is toggling shpere's appearance between red color and the texture applied on it , by pressing the T key . I came upon a very weird bug :
If I Build and Run my project , the texture is applied as desired when toggling , but If I click on .exe file (from the same build) and run it again , it doesn't , just stays white (cause , as you can see on my code , I first make the sphere white and then apply the texture) . I've also tried all the possible build and run , and build combinations by changing locations etc and the problem persists . Also when I hit play , in the Game window of unity editor it runs as expected . Only when clicking on the .exe is the problem .
I guess , with Build and Run , unity still uses editor's Assets ? Maybe the devil lies in the dll's or the Resources folder ?
I'm posting also images , of the states I said above .
Build & Run :
when I click on .exe :
By the way , color apperas different , cause a Random.Range code run .
