Unity Engine

Can some one help me figure out why this code doesn’t work

I need to Change the smoothness and other properties of the shader on alot of objects after there created

loadedObj.GetComponentInChildren<Renderer>().material.shader = Shader.Find("Standard");
        loadedObj.GetComponentInChildren<Renderer>().material.SetFloat("_Glossiness", 0);

Hm… I’m thinking… thinking… thinking. I GOT IT!!! I think it doesn’t work because there’s an error.

Here is how to deal with crazy hairy nasty dirty lines of code like the above:

One thing per line, check each thing along the way, find out which part is NOT what you expect it to be.

Generally, since only a few people here are mind-readers, here is how to report your problem productively in the Unity3D forums:

somebody should really pin this stuff, and highlight it… twice.

SetFloat("_Glossiness", 0) likely should be SetFloat("_Glossiness", 0.0f).

Changing 0 to 0.0f instead won’t make a difference. The compiler will convert the integer to a float automatically as that is what the method wants.

I ended up getting this to work Thanks guys

    IEnumerator Run() {

        //file path
        //string filePath = @"F:\VATICMOD\Data\azeroth_37_31.obj";
        //string filePath = @"D:\Models\world\maps\silvermooncity\silvermooncity_44_12.obj";
         string filePath = "Assets/Resources/world/maps/silvermooncity/be_signpost_eversong.obj";
        if (!File.Exists(filePath))
        {
            Debug.LogError("Please set FilePath in ObjFromFile.cs to a valid path.");
           
        }
        //create stream and load
        GameObject loadedObj = new OBJLoader().Load(filePath);
        Debug.Log(loadedObj.name);

        foreach (Transform g in loadedObj.transform)
        {
            GameObject f = g.gameObject;
            f.GetComponent<Renderer>().material.shader = Shader.Find("Standard");
            f.GetComponent<Renderer>().material.SetFloat("_Glossiness", 0);
            Debug.Log(g.name);
        }
       // string newPath = "F:/VATICMOD/Assets/Resources/world/maps/silvermooncity/silvermooncity_44_12.fbx";

        //FBXExporter.ExportGameObjToFBX(loadedObj, newPath, true, true);

       // ObjExporter objExporter = new ObjExporter();
        //ObjExporter.MeshToFile(loadedObj.GetComponent<MeshFilter>(),"test.obj");

        yield return new WaitForSeconds(0);

    }
