Do You Need To Learn Programming To Learn Blender

Don't larn Blender Scripting.

Acquire how to program instead.

I demand to come make clean about that title: this is not and anti-Blender rant, y'all definitely should acquire the Blender API if you lot are and so inclined, or need it for skill edifice or work.

And so why did I start with that championship, and then? Well, considering I need your attention, peculiarly the attention of the programming newbies.

Now, I gotta make one affair clear: this mail is long and is aimed at those who want to take upward coding for serious production. If you don't like to read long posts, or are not thinking nearly hacking Blender for production environments, and then yous can browse away now.

"This post is for warriors. You lot're not a warrior, bye!"

A scrap of back story.

My name is Jonathan Acosta, I'thousand a self-taught Web developer. I've been the developer backside Alloy Swap for the last v years.

I started out as a total newb to the craft of coding for the Web. I've gained a lot of feel past sheer trial and error. Just with every mess up and headache has come up great learning and refinement of my hacking skills.

I wrote my first "Hello world!" program in Javascript, back in 2006, while following a simple W3C tutorial on bones website programming. Back then I had to forcefulness myself to learn how to read code documentation and API references, it was a constant struggle and I really didn't take a big goal in mind, other than learning how to programme. the adjacent twelvemonth I tried some Processing, and even wrote some tools for it, which unfortunately are now extinct because of my lack of time for maintenance.

My time with Processing lead me to programming other things later on in life, and eventually led me to having my ain personal business as a freelance Spider web developer. It is a task that I enjoy a lot and I hope to continue doing for many years to come. The Web is always changing and putting new challenges in your way, and takes the boredom out of the equation. Plus telling computer what to practise feels great. ;)

Now, I gotta exist articulate: I'm Not an expert in everything in that location is to know about writing code, just I do have some insights about software development and I'd like to contribute some words of advice for the newcomers.

So, yous wanna script the crap out of Blender?

Many of the states will reach the betoken when Blender won't be able to do exactly what we want it to do. Many take already gone through that, and now those moments are landmarks for the nascency of new, incredible Blender addons, like the epic Retopo Menstruation and Muscle Tools. These plugins stand out from the rest considering they implement functionality that Blender lacks completely, and likewise because of the very professional user experience you lot go when using them.

These tools didn't only arise from the developers waking up i Saturday morning time and simply maxim "I'm going to script this awesome new feature for Blender, even though I don't know anything almost coding."

No. The creators of these and other slap-up tools take honed their skills to the bespeak they are able to get almost anything done with the Blender API. These skills are congenital on top of one another, in increasing level of complexity and power, from the very basics of what programming is, to very avant-garde topics like writing your own clever algorithms, classes and libraries.

They needed good working knowledge of the basics of programming principles, the linguistic communication they're working on, and the API their software is based upon, in this example Blender'south API.

If you wanna play in the aforementioned field, you'll have to build those same skills, because otherwise you won't exist able to program amazing things, or maintain and fix your code, much less change or customize somebody else's.

So here are some recommendations for the newbies well-nigh how to write groovy code, from your first "Hello world!" program, to your amazing brand new addon.

one — Forget about Blender (for now), learn how to program starting time.

Practise you know what a control construction is? A form? An instance? An object? An array? No?, then you should NOT be learning how to script for Blender right at present. Instead you should exist learning the very nuts about programming, what it is and what you can accomplish with information technology.

Programming is both very easy and very hard, at the same time.

The basics of programming are simple plenty that you lot'll have a skilful understanding of them in a calendar month or and so. But implementing your desired functionality is sometimes hard, very difficult; and fifty-fifty more than and then if yous don't know the basics about writing your ain types, functions and classes; instantiating those classes into objects, and using them to accomplish your goals through logic operations, iteration, error handling and debugging.

Did that terminal paragraph sound like an obscure witchcraft incantation to yous? And so you should exist learning how to plan right at present. Believe me, I didn't say anything obscure upwards at that place.

Why am I advising yous to larn programming start?

Well, just as a rhetorical exaggeration, I've lost the count of how many times I've seen users request this on the Alloy Swap Questions section:

" How do I larn scripting in Blender ?"

I've too received PMs about the same topic.

My answer to those questions nearly how to script for Blender has always been the aforementioned:

Learn programming first. Then learn the Blender API.

Why? Because you won't exist able to adapt your lawmaking to changing atmospheric condition if y'all don't know how to use logical operations with if-else statements; you won't be able to batch process a bunch of mesh objects if you lot don't know how to utilise a for or while loop; your scripts may become huge, unmanageable, spaghetti-like jumbles of code if you don't know anything about encapsulation, modularity and unmarried-responsibleness code.

What happens when the code you re-create-pasted from an old scripting tutorial doesn't work anymore? Can you effectively read the Blender API documentation in order to fix it on your own? Can you enhance, fix and extend somebody else'south code? Tin you add new features to it?

If you lot learn the nuts of programming you will be set for anything that may come in the hereafter, yous'll be able to modify, optimize and even completely re-write entire scripts with better implementation and clever algorithms that otherwise yous volition never know how to write.

This is a adequately common noesis hole in the Blender customs, but very specially for BGE-based game developers, they desire to make the next gaming big hit, simply they mostly accept no basic knowledge of programming to achieve that goal, and if at that place'south one field in 3D that requires you to know programming, that is game evolution.

Of class at that place are no culprits to this hole in our noesis as a customs; no 1 is to arraign. Most people have never had the need to know how to code considering a corking deal of tasks tin can completed in Blender with mouse deportment and keystrokes. Others, I'm sure, are intimidated by but the thought of having to learn how to program.

Also, and as far as I know — and compared to all other Blender pedagogy topics out at that place — , Blender API educational courses and tuts are very scarce; there's shut to zip quality content about programming for Blender[*], while the rest of the program has been extensively covered by awesome education sites like Blender Guru and CG Cookie.

I aspect this to the fact that 3D artists are precisely that, artists. Programming hasn't been truly needed to produce art until recent years, but nowadays 3D industries like VFX, gaming and data visualization are growing exponentially and they all demand a good grasp of programming from those interested. Beyond this, there is a very articulate tendency for the hereafter likewise: programming volition be an integral slice of every function of life, learning how to code volition not simply help you attain your current goals, but it will as well open better opportunities for y'all in the time to come.

2 — You should learn a programming language well.

So now yous wanna larn programming. Awesome!

Don't exist intimidated by the task at hand. Every bit I said before it's easier than yous think. But exist warned, I likewise said it is harder than y'all think, at times, really freaking hard, and one of the contributing factors to having a hard time learning how to programme is the language you choose to larn.

A few years back I started learning C++. It was nearly impossible for me, because while it is tremendously powerful, it is also circuitous, full of weird syntax and counter intuitive features. I certainly do NOT recommend you trying to learn C++ as your first language; although, if you really learn information technology, any other language will be way easier to write compared to it.

We are very lucky about the Blender developers' option for the scripting language it supports: Python 3. It is powerful and piece of cake to learn, it comes wrapped up in every Blender installation and you accept admission to it correct there in Blender's console and text editor.

The logical decision is that, if y'all're going to script for Blender, but you don't know how to program, and so you should be learning Python.

At present, getting started with Python can be a scrap weird if you lot oasis't written a single line of code yet. Then I'll link yous to this awesome online, in-browser Python form on Codecademy. You don't have to install annihilation to your computer to follow along, only open the page, signup and complete the course; information technology will get you lot started with the basics of programming with Python, it will teach you the very basics: from the archaic data types and control structures; to lists and more than complicated types; to loops, functions, classes and methods.

This advice also applies if you're beginning with Web development and y'all want to develop your site in, say, CakePHP or Laravel, you should know how to program and also some PHP before you dive into the frameworks, aforementioned for Browsers, Node.js and Javascript; Unity and C#, Django and Python, Rails and Ruby.

3 — Any course you start, brand certain y'all finish it.

This is an important function of learning how to program. Some topics will be difficult to dissimilar people depending on the experience they get out of a grade. Eventually you volition come up to understand those hard parts, only it is of import to have them, at to the lowest degree, mentioned to you in courses and tutorials. Put some other way: if you find a topic peculiarly difficult while learning how to programme, don't skip it, read it anyway, you'll likely see that topic again in the future; equally you lot're repeatedly exposed to the concept you go more likely to finally understand what it does and how to utilize information technology.

For me, the part I had to become over and once more was Object Oriented Programming (OOP), writing classes was very difficult for me at the offset because I didn't sympathise how the classes related to my code, and how I was supposed to use them; to me it was just a complex and mysterious thing I might never understand. Luckily I kept myself from ignoring it, I felt kept telling myself, perhaps if I read information technology enough times somehow I'll eventually understand information technology.

In the end this approach worked, I just needed to be exposed to the concept until the "ah-ha!" moment came to me. I'm nonetheless no absolute good nearly OOP, simply I have a good understanding of how to write and utilize a well structured form to make my code modular, easy to read and maintainable.

Finishing a course will also give you a corking sense of accomplishment: y'all but went through something that was difficult but you pushed your limits, and yous came out victorious, you may still have some weak points to work on further, simply now you're non a total newb anymore. And that is something nobody else can do for you. Completing a course is particularly rewarding if the class offers a document, fifty-fifty if it's a symbolic one.

4 — Finally, yous should learn the API you need to learn.

For our purposes you wanna larn the Blender API, of course.

Once you're comfy writing code in Python it is time to apply your new knowledge to Blender, and to acquire it'south extensive API (Application Programming Interface). APIs as the name suggests, are custom office and class interfaces with the environment you're dealing with (in this case, Blender). An API contains custom classes, functions, objects and data that you tin admission to instruct the environment to exercise things for you. Web browsers have APIs too, so when you write Javascript for browsers y'all're instructing the Browser to practise things for y'all and your website user's.

The Blender API facilitates access to the internal objects and data that make Blender tick; by having access to those objects and data you will be able to tell Blender what and how to do things for yous, from very simple tasks to completely new features, tools and workflow enhancements.

So learn the Blender API, learn it well, just only after y'all know how to program. This will reduce your suffering, and your having to post to forums and get no answers because no one else knows how to programme. Get familiar with reading documentation, you'll keep doing it equally long equally y'all have to lay down some code.

Now, at that place's another thing I have to make articulate here: I've spent nearly no time programming for/in Blender, I've seen many code examples and I've been able to fifty-fifty raise other people's code[**].

Of course, that's not a big accomplishment with Blender scripting past whatsoever means, but then again, that was something I was able to reach because I have good working noesis of how to program and how to read code and documentation; in my opinion, that's more than valuable in programming than annihilation else.

That's it! This can (and should) lead to more than discussions coding and advice for newcomers; by all means, leave some comments with recommendations and critiques.

Was I besides harsh communicating my thoughts? Good.

Do you regard me as a hypocrite for not really knowing the Blender API? That's probably right, but I don't intendance: the main goal of this slice is getting all programming newbies to up their level, so they suffer less when confronted with incomplete documentation, broken code, missing features, deprecated APIs, third party code that needs fixing, debugging nightmares and and so on.

Thanks for reading, see you on Python heaven.
