Challenge 1: Shader property

Complete a shader skeleton with a Properties block.

Challenge 1: Shader Properties

In ShaderLab, the Properties block exposes parameters to the Inspector. Colors, numbers, range sliders, and textures are declared here.

Properties {
    _Color ("Main Color", Color) = (1,1,1,1)
    _Glossiness ("Smoothness", Range(0,1)) = 0.5
    _MainTex ("Albedo", 2D) = "white" {}
}

These exposed attributes are directly accessible from C# scripts via material.SetColor and material.SetTexture.

Exercise Shader property name test

Define a Start method. Inside, declare string propertyName = "_MainColor"; and print "Shader ozelligi: " + propertyName to the console.

Show example solution

using UnityEngine;

public class ShaderPropertyTester : MonoBehaviour
{
    void Start()
    {
        string propertyName = "_MainColor";
        Debug.Log("Shader ozelligi: " + propertyName);
    }
}

Exercise Shader glossiness value test

Define a Start method. Inside, declare float parlaklik = 0.8f; and print "Parlaklik degeri: " + parlaklik to the console.

Show example solution

using UnityEngine;

public class ShaderGlossTester : MonoBehaviour
{
    void Start()
    {
        float parlaklik = 0.8f;
        Debug.Log("Parlaklik degeri: " + parlaklik);
    }
}

Test yourself

When '_MainTex ("Texture", 2D) = "white" {}' is declared in ShaderLab Properties, which method is called from C# to assign this texture?
- material.SetPhysics
- material.SetAnimation
- material.SetTexture
- material.SetAudio
Show answer

material.SetTexture — To update 2D texture shader parameters via code, the material.SetTexture function is invoked.

Declare range slider property

Properties { _Glossiness ("Smoothness", ____(0, 1)) = 0.5 }

Show answer

Properties { _Glossiness ("Smoothness", Range(0, 1)) = 0.5 }
