General
Visual Scripting
Introduction
1st let me come right out and say that I am not a fan of visual scripting for general programming or really any use case.
I understand that some people are intimidated by the prospect of learning general scripting and programming.
I understand that some people think it will take to long to learn scripting and that somehow visual scripting will make it faster.
My goal with this document is to help people see that learning to write the types of scripts you would need in Unity is easier and far far faster than learning to use Bolt, GameMaker or other visual scripting tools.
My main arguments are this:
Scripting is simply typing words. You probably already know how to type so you already know more about scripting than you likely do about a particular node graph editor (what those visual scripting tools really are).
Second, the "hard part" of creating a script isn't the typing of words, its the understanding of systems, data structures, how to manipulate all that to get the desired results ... the "Programming" of it.
Visual scripting doesn't change the programming aspect, in many cases it makes it harder since visual scripting tools are always far more limited than text based scripting.
How can I say they are always more limited?
Visual scripting tools write script for you, they are thus always behind the current state of text based scripting or at best almost (but not quite) as complete.
Learning Resources
Node graph editors (the visual scripting tools) are all proprietary. That is they are made by and maintained by someone specific. As a result there are fewer resources and less general support for them when compared to standard tools and concepts.
In contrast C# the primary scripting language used in Unity is a standard and open language with a truly massive amount of resources. Perhaps its the overwhelmingly large number of resources that have put you off learning, so to help you narrow that down to just 1.
Junior Programmer - Unity Learn
Unity Learn
The only resource you will likely need
This course is free, doesn't take long at all and will take you from "installing Unity" to creating some of the most common scripts you will need in Unity.
This course goes on into more advanced subjects if you would like to carry your knowledge forward.
How long will it take
I can say if you start now with the program I linked you will have your first scripts written and working possibly in minutes maybe as long as a couple hours.
Exactly how long depends on the person but I can say logically it would take less time to learn to do a thing in script than it would to learn to do the same thing in visual scripting.
Why?
- 1.The "hard part" to learn is what can be done and how to do it i.e. the "programming" part. You still have to learn that with visual scripting ... all visual scripting does is remove the need to type words it does not remove or even change the process of learning system design, understand data structures, etc.
- 2.You already know more than you think you know when it comes to scripting. When it comes to learning a new node graph editor you know nothing, so you already have a head start on learning scripting.
- 3.There are far more resources, larger communities and far more mature and developed tools, courses, etc. for text based scripting/coding than there is for any flavor of visual scripting tool.
- 4.I can tell you from experience that many things are far more complicated in visual scripting nodes than they are in text based script. In some cases its simply not possible to do in visual scripting or cant be done in a way that is functionally performant. This is actually more common than you would think.
I just want it to work now!
I just want know how to make it work!
If you take the time to understand the basics everything else will come faster and easier. The fastest way to reach your goal is to do it the right way first.
Just a little quote form James that I find I use a lot.
So start scripting now. The time you spent reading this far in this document you could have gotten through your first script in the Junior Programmer course I linked above ... assuming you skipped the how to install Unity ... I assume you already know how to install Unity.
The thing to understand is that the "hard" part of learning to script is the programming part, that is learning how to design and implement systems that yield the desired results with minimal resource (CPU, RAM , etc) used.
Visual scripting does not make "programming" "easier" you still have to learn how to create those systems, why they work, when to use them, etc.. All visual scripting does for you is makes it so you can drag and drop nodes as opposed to type words.
I still insist that you already know how to type words faster than you likely know how to drag and connect nodes.
You also already have prebuilt knowledge of written communication that means you know more about how a script file would be constructed than a node graph.
For general scripting I really struggle to see any use case where working in a node graph would be faster or easier or yield better results than to spend a small amount of time to learn the basics of scripting.
