Hello, welcome to this lesson in Unity. In these lessons, you will learn new features in Unity, including Scriptable Objects. Community Hub, create a new project. It's like 3D URP. We'll name this project Extras. We'll set the layout to default. We'll create a new scene, choose Basic, URP. Save the scene as Scriptable Objects. We'll quickly create a simple NPC patrolling, several waypoints, then create Scriptable Objects that can be used to adjust data for each NPC. If you don't have the nav mesh system installed, get it from the package manager. Create a plane, reset it, scale it to 3 in X and Z, add a component, search nav, add a nav mesh surface, bake the surface, next add a cylinder, name it Waypoint, reset it, set the Y position to 1, move it to a corner of the plane, duplicate 3 times, and move to each corner. Select all the cylinders, set them to static, select a plane, do another bake. Next, create a capsule, name it NPC, reset it, set Y to 1, and position. Right-click on NPC, add a cube, click enter, scale the cube down, move it forward in the Z direction, along the blue arrow, indicate which way he's facing, select NPC again, add component, nav mesh agent, and collapse these panels. Open the Scripts folder, or create a Scripts folder, create a new C-sharp script, name it NPC, select NPC, add the script to the inspector, open the Script and Visual Studio, add a library, we'll add some variables, initialize the agent, this is done in the start method, after update, make some room, and we'll create our Patrol function, the update, we'll call it to Patrol, save the code, return to Unity Editor, confirm the NPC has the script attached, and we see the speed is a public, for the Wavepoint, open that up, we can do it, we can drag each Wavepoint in, this will automatically create a slot, save the scene, press play, NPC should do a basic random Patrol, add a steady speed, now let's say we want to change the speed to the NPC, any inspector while still in play, change the speed to 10, let's say that the speed we would like, and if we duplicate the NPC, we want to set a different speed, stop play, and the inspector, the speed reverted back to the default 3.5, thanks for watching!

Course Description

In these lessons, you will learn about scriptable objects, visual scripting, and the shader graph. We will explore these advanced features of Unity and incorporate them into a simple patrol routine. By the end of these lessons, you will be able to create a scriptable object, code with visual scripting, and create a custom shader.

We’ll go over what a scriptable object is and how to create a simple NPC patrol scene where we can change the variables using a scriptable object. You will also learn how to create a custom menu in the Unity Editor to generate scriptable object assets. Visual scripting is now built into the Unity Editor, and we will explore the visual scripting graph interface to create code using a node-based system to connect trigger nodes and variable nodes to adjust parameters in real time. You will create a simple script, analyze the components of the script, and re-create it entirely using visual scripting. Finally, we will explore how to create your own custom Unity shaders using the new shader graph system, which is another node-based way to visually build complex effects, such as an animated fire shader.

What You'll Learn

Create scriptable objects and build a custom Unity Editor menu to generate scriptable object assets
Build a simple NPC patrol scene whose variables can be changed using a scriptable object
Code with Unity's built-in visual scripting machine using a node-based system of trigger and variable nodes
Re-create a script entirely with visual scripting after analyzing its components
Create custom Unity shaders with the node-based shader graph system, including an animated fire shader

Key Takeaways

The course covers three advanced Unity features: scriptable objects, visual scripting, and the shader graph.
Scriptable objects let you adjust variables in a simple NPC patrol scene, and a custom Editor menu can generate scriptable object assets.
Visual scripting is built into the Unity Editor and uses a node-based graph that connects trigger nodes and variable nodes to adjust parameters in real time.
The shader graph is a node-based way to visually build complex effects, demonstrated by creating an animated fire shader.

Frequently Asked Questions

It covers scriptable objects, visual scripting, and the shader graph, incorporated into a simple patrol routine.

Will I learn visual scripting in this course?

Yes. You will explore Unity's built-in visual scripting graph interface, create a simple script, analyze its components, and re-create it entirely using the node-based visual scripting system.

What will I be able to do by the end of the lessons?

You will be able to create a scriptable object, code with visual scripting, and create a custom shader.

What is a practical example used to teach the shader graph?

The course shows how to use the node-based shader graph system to visually build complex effects, such as an animated fire shader.

What skills does this course focus on?

Custom Scripting, OpenGL Shading Language, and Script Component.
