Blender Python Tutorial : An Introduction to Scripting [how to learn python for beginners]

[@KenanProffitt]

Really cool man. Nice work! The community could use more of these types of videos.

[@DarkfallBlender]

Thanks Kenan!.. It's nice of you to say so!. I think there are some really good tutorials out there but many of them expect you to have some level of scripting experience. I wanted to be able to show people (like me) who think they could never write an Add-on, that it's actually possible. I never would have thought that my Add-on would be used by so many or even be of any use..

@@DarkfallBlender something more of automation using python so you know i don't have to copy paste sh*t again and again, and be able to shade multiple objects and tinker them fast, so mostly automation because that's kind of a big power of scripting, also if we can make our own plugins like the gis and stuff, i know that stuff is advanced but wanna do it one day... also, using scripting a lot of people have created art, so it would be fun to have a walkthrough of that too, so we understand automation better I really love your videos btw, scripting in blender doesn't have many tutorials on utube

[@cultofape]

This was the first blender python tutorial I´ve watched that didn´t either dumb too much down, or rush things through without explaining what each step does in a good way. Good job!

[@DarkfallBlender]

Hey brilliantApe, I am really glad you found it helpful! I am still learning so I may "gloss over" some things every now and again though if I do, feel free to ask me and I will try my best to help.. Or at least point to relevant information 😁.. I have a little collection of scripting videos that are growing, so if you have any ideas or suggestion on what you want to see, I can try to cover it in future videos.. Anyway, thanks again for the comment!, it's great to see these videos are being useful!..

[@cultofape]

@@DarkfallBlender Some people might think writing tutorials when you´re still learning is a bad thing, but I disagree. When you´re fresh learning you still value every step of the process and and don´t gloss over things that become second nature to you as you get more advanced. It´s also a great way to repeat what you´ve recently learnt in a structured way. Even the mistake you made with the icon caused you to bring up the icon viewer addon, which I did not now about :).

[@DarkfallBlender]

Lol yeah I see what you mean.. I just hope I don't mess things up too bad 😅

[@mrhertz9940]

I build add-ons and utilities like this in Adobe products for fun, and to make my job less onerous. I actually hadn't even considered creating one for Blender - but as a hobby 3d guy, I think I could do something that would help people. Down the rabbit hole I go, again. So thanks for this. : D

Was just curious how blender scripting worked. This was an amazing tutorial with the right pace for newbies. Unsure if ill dive deeper, but really informative.

[@DarkfallBlender]

I was the same when I started (which wasn't all that long ago). I wanted to see if I could automate some things so I didn't have to repeat the same steps when using blender and it turned out to be easier than I thought. After a little while I started to develop the VFX Nodes Add-on.. I think everyone can benefit and utilize python in one way or another depending on what they need. I am glad you have found this video helpful and I appreciate the comment! 👍

[@fyisic]

@@DarkfallBlender Why i am interested in scripting in blender is that i it should be great tool using math to make cool looking structures. If you are interested in what i am making you can check out "Shpongle - Behind Closed Eyelids" on my channel and go to 3:40 .. I used vertex points from mesh to make the shapes. I am making same thing for another project but this using thousands of vertex points. Maybe just maybe ill take a dive into it. But have plenty to do as is :P

@@DarkfallBlender I used to develop closed loop gif math-art animations with Java/Processing but switched to python/Blender about 3 years ago. Every time I looked for learning material it seemed there was nothing really out there so I just cobbled together a very basic working understanding from examples on the web. I've watched your tutorial 1 & 2 so far. It's very addon related but that's okay because perhaps I will wnat to do something like that in future. Embedded within it is also a primer to getting going with 2.8, which has change substantially - so much so my 2.7 based code kept blowing up in it. Anyway, I'm going to try learn about properly now. Your material is my starting point. Thanks! What I need to find next is some good theory on manipulating meshes, edges, using creases, mechanics of materials / colouring and driving the tool to generate a scene renders. I especially need to start manipulating existing objects - what I did with the older version was build up all objects from scratch and then tear them down for each still image. :)

[@DarkfallBlender]

You can use Python to control or run functions in any context. So not just modelling!.

[@ChippWalters]

It's great you create these as someone new to scripting because you don't take things for granted. Case in point: your explanation about how to add icons was super-- and even included reference to the icon add-on. Perhaps you should consider creating a paid for course that can be continually updated in small increments as you learn new things. This would give you incentive to continue with the course, plus be a good (if not the ONLY) Blender 2.8 scripting course. Great job!

[@DarkfallBlender]

Thanks for saying so Chipp!.. I was always hesitant myself to learn Python. I kinda thought it was something beyond me, but after attempting my first add-on it was actually quite fun.. I then wanted to show others that it's actually possible to create your own add-ons and if a beginner like me can do it, then anyone can.. As for creating a paid course, I doubt I am qualified enough for that. I will happily continue this series as long as everyone finds them useful. Again thanks for the Comment Chipp! 👍

Sure thing. To "finish" the add-on, you of course would like to be able to install it and then never worry about it again..

I am new to blender python script . Is this course in python 3 or 2 ? Does this course need any prerequisite ? For me this seems pretty complex but I am interested . I have understanding of C#,c and little knowledge of python 3.

[@DarkfallBlender]

I think it's Py3.. You won't need any previous experience but it will help if you do..

[@brockbrown1629]

I notice you didn't do the init function, and you didn't declare the attributes with self.[attribute] = [thing]. Is this a new idiom for Python 3 or something? I always thought the whole traditional init thing with self.variable for every initialization was kinda chunky.

[@DarkfallBlender]

init is certainly still used and I think is the more acceptable way of coding, though Blender does not specifically need an Innit function which is stated in the API i believe.. As for the att I think declaring them in a property group and then using a pointer is tidier but again you certainly can declare them as you said..

[@zion6680]

Mate can you make a video on how to possibly make a simple script that'll tie the coordinate stuff in the Bisect tool to a plane that can be re-used to replace/resuse the cutting object/plane as an offset.

Hy there, interesting video and I am actually just starting to learn python and in a sense of blender related stuff....so here s a question.....bl_label, bl_idname and all that stuff...did you just follow templates to get to understand it or what? In one of templates I ve seen same line of order of things, so I m just curious like....did you just write it because its there or....? Trying to get a grip of why those labels need to exist and how did they end up being named the way they are? Its probably all from info line but....damn there s a lot of stuff to rewrite then for each thing we try to make?

[@DarkfallBlender]

Hey Pavao, So the Blender python API is a great place to start : docs.blender.org/api/current/index.html Specifically the section : docs.blender.org/api/current/info_quickstart.html You can search for pretty much anything there. So yes a little of copying the templates at first but also reading the API helped a lot.

[@mack7963]

hi, firstly you make it so easy to understand how to script, so you said to suggest ideas, so here goes, i call this Snap to Black, basically its an add on that snaps the cursor to the colour value 0,0,0, the add on would have a load blueprint button that would allow the user to select 3 images, once selected it would load those images onto three separate planes, i believe load image as plane would probably be the best option, the planes would be positioned as you would if you were to do this by hand, once this part has been done the user could then start drawing curves, the options that would be available would be to place a start and end point and have the computer follow the blueprint between the first and last point, a point count would be available or the user could simply follow the blueprint lines manually, a mirror option would also be available, once the desired curves had been drawn a button would allow the curves to be joined creating a mesh, a curve network feature would also be available so that 4 curves could be drawn and the computer would then create a mesh from those 4 curves. i don't know how possible this is or how much work it would take, but i do know that programs like rhino, Modo, 3DS max, Maya or Cinema 4D have a feature like this and it would make using blueprints easier than before......a lot easier. so there you go that's my suggestion for an add on that i think needs to be made.

[@DarkfallBlender]

I would say it's likely that this is possible though my knowledge is rather limited so I am not sure of the process..

[@MegaCyberpirate]

yes. You can definitely.. First you have to select your object To select an object you have to use the following commands :- obj = bpy.context.window.scene.objects["Cube"] #selection by name or you can simply select the active object by following cmd :- obj = bpy.context.active_object # selection by active object in 3 d view after getting the obj instance you simply call the location method by the following syntax :- obj.location # this will returns a vector of location or obj.location.x #returns x co-ordinates Now you just simply have to store these co ords... Hope this helps..

My script is the same as yours but the tab won't appear?

Hey BHF, if the tab is not being displayed, most likely it is because of a minor error. Either a typo in the Operator/Panel or in the Registration Section. When you run the script does it kick up an Error message?. If it does not, you can Check the System Console. (To do that : At the top go to Window > Toggle System Console) If you hit run it should point you to where the problem is.. or If you want you can post your script here: pastebin.com/ Send me the link and I will take a look.

[@DarkfallBlender]

Hey Edwin, yeah some things generally change but it's not always obvious. For example, in older versions you may find icon names have now changed. Nodes have been changed and so on. You can check the System Console to see if there are any errors (generally it does a good job in telling you what you need to fix). I have done a video on reading error messages and how to fix them if you have not seen it already you should check it out: kzbin.info/www/bejne/gZjUnqhng8yXrLs If you are still having trouble you can post your script to pastebin.com/ and I wil take look when I get chance.

@@DarkfallBlender I found your script on your blog page and copied and pasted it and that ran so I compared the two and I couldn't see where I had gone wrong in following your excellent tutorial. No matter, I can now proceed to develop my addon. Great tutorial style - thank you. Also, unbelievably rapid response time.

[@DarkfallBlender]

No problem, let's call it a phantom bug lol.. Good luck with your project 👍

[@ScminizationMusic]

5:47 Wait, is there a difference between using " " and ' ' ?

[@DarkfallBlender]

Good Question.. Sometimes it means nothing and other times it can mean the world!.. Cryptic? 🤔... sure is 😂.. What I mean by that is, In some instances you can use either one and it will be fine. But then in other situations you will need to use one or the other. For example, when defining an Icon in a panel we must use ' '

I wrote a script to animate the solar system , do you think I can turn it into addons

[@DarkfallBlender]

If you have wrote a script then you are halfway to creating an add-on.. we simply just need to package it up!.. In the video that follows this one I show how we can turn our script into an add-on ready to be used in Blender you can check it out here: kzbin.info/www/bejne/nneQlKx-bb9qjbM

[@butayama7829]

Searching a solution for a problem I watched your tutorial and enjoyed it. Could you give a hint where I can find an explanation how I can display the content of a Rotation attribute of an object as a Text within a Scene which could be rendered?

[@DarkfallBlender]

Interesting, So you want to say have an object (lets say a cube), that has been rotated, you want to display the rotation value as a text object for the 3d View? That about right?.. Off the top of my head, It seems like it's possible and we have already looked at adding custom text in the Text Tool Video here: kzbin.info/www/bejne/anzagZuHjZtmibM Though it's not exactly the same, I think it would be very similar...

[@butayama7829]

Following your linked tutorial above, which I like very much, the value of the object attribute is now displayed as text object. I used in the class definition. The next step I want to take is automatically update the text object with the actual value if the attribute object ("Cube") is rotated. I've found a question at blender.stackexchange.com/questions/31814/how-to-drive-text-based-off-of-a-value where a solution from M.O.Z.G using the Add-on "Animation Nodes" is presented. I didn't get the setup running. I haven't found out how to use the attribute object as driver and generate frames with the updated text object for each rotation step. A simple use case would be the display of the value of the angle of two objects in a render sequence. The angle measure tool does something alike (if adjusted after each rotation step by hand), but it does not seem to get rendered.

[@DarkfallBlender]

Seems more complicated than I originally thought.. The Stack Exchange is great.. you Should post your problem and I am sure someone will know a way to get what you want.. If you don't find the answer you are looking for you should try Stack Overflow..

[@KeyboardThumper]

Nice vid, BUT...the tab 'NewTab' doesn't show up in Blender 3.1.2. Any ideas please?

It's probably when we use = when defining a property.. In newer versions of blender you need to use : not =

question how would you write out for tab not to be included in another script. Like i have the Tabs interface and i want to keep the object adder and shader library off to the side but it keeps getting included in the tab panel.

[@DarkfallBlender]

Uhm, What? lol.. So the Object Adder and Shader Library are currently in the Tools Panel on the Right (accessed by pressing N), I am not sure what you mean by tabs interface?...

Hey Yogita, It could be a spelling mistake or typo, you should check your code and make sure it's the same.. Also you can find the problems with help from the System console.. When you run the script what error message do you get?

It's probably about how the file loaded into the KZbin app but the video is all black. Moving slider makes preview box show video. Funny mountain range graph image shows along slider bar when it is moved. Reopened. All is fine

Thank very good !! It 's possible to do a input scale for a cube for example ? (sorry for my english )

[@DarkfallBlender]

Hey Jim, thanks for the comment!.. I am glad you like it.. As for your question, do you mean scale before adding the Cube or having a properties option in the panel?.. I assume you mean, you want to enter a value of scale, then press the add object button with that specified scale?..

[@jimbotht1091]

@@DarkfallBlender "you want to enter a value of scale, then press the add object button with that specified scale", > Yes exactly :)

[@DarkfallBlender]

I'm pretty sure it could be done. I know we can add properties to the panel to change the scale after the object has been added, so there should be a way to preset the scale as a prop. I have some Ideas but not an actual solution as of yet.. I can look into it and if I find something helpful I will include it in a video!.. Thanks for the suggestion

Hi thanks for the slow and good tutorial :) I was wondering, I encountered an issue where I cant add a third button to the UI. I dont get any compile errors or the like. Whats up with that?

[@DarkfallBlender]

You should be able to add as many buttons as you want so I gotta assume its a minor mistake.. If you get no Error on Run, still Toggle the System Console and see what it says.. If you want you can post your script here: pastebin.com/ and send me the link I can take a quick look..
