Blender 2.90 Tutorial, learn python scripting (for beginners)
Content
0.32 -> Hey everybody and welcome back to another python scripting tutorial
3.74 -> though this time, It's the first in blender 2.9
6.56 -> So as I mentioned in the last video, I want to take a look at an error message and how we can fix it
10.96 -> So let's go ahead and jump right in
12.64 -> i'm going to change this to the scripting workspace
16.32 -> Then let's make a little bit of room over here
18.94 -> now, let's get rid of the python console
20.498 -> don't need it
23.359 -> So i've already installed the add-on if I press n
26.24 -> Go down to the shader library
27.76 -> So for those of you who don't know the shader library is just a simple add-on that will add a shader
33.44 -> So if you want to download this it is a free blender add-on
35.76 -> There will be a link in the description to our blog go ahead and check that out
38.879 -> So this all worked fine in previous versions of blender?
41.84 -> But in version 2.9
43.44 -> We can see the stylized section no longer works and if we go down here to the info window if we just scroll the mouse
49.12 -> We can see this error code pops up.
51.12 -> So let's make a bit of space.
52.78 -> Let's read this error message. It's quite a big one
56.239 -> And then if we scroll through all of this don't worry about all of this text right now i'll explain what this means
61.039 -> It's not important
63.68 -> So, let's just scroll all the way up to the top here
66.32 -> So this is what your error message looks like
68.159 -> And by the way, it now has a red x which is a nice little addition to blender 2.9
72.799 -> So we can see right here. It says line 167
75.84 -> So if we had the script open, we'll be able to see where it is. So let's go ahead and do that
80 -> So you could just go to open and find the script
83.04 -> But what i'm going to do instead is go to one of these options here
86.88 -> I'm going to open up the search operator for me. It's spacebar, but for you, it could be f3
92.32 -> Then i'm just going to type edit source
95.2 -> And then click this and it'll open up the script for me
102.4 -> So now with this script open, I want to go to line 167
106.72 -> just scroll down
110.48 -> It actually displays the line of text here so we know it's a problem with something in this line of text
115.92 -> Then if we go down it says type error
118.64 -> Error with keyword argument icon so we know it's a problem with somewhere within this icon
123.92 -> So if we keep reading it says force underscore smoke flow not found in any of this list
130.399 -> And this is just a list of all the possible icons that you can use, so don't worry about all these
135.36 -> It's just saying that the force underscore smoke flow is no longer in this list. So that's all it is
140.239 -> It's just changed an icon so we can see over here force underscore smoke flow is no longer being used
147.04 -> so if we change this to say question
151.76 -> Since we know it's here
153.84 -> now if we run script
155.68 -> We can see these options are now being displayed. The only problem was the icon
159.84 -> So yeah, maybe icons have changed you need to go through your options and just make sure there is no errors there
164.879 -> It's definitely worthwhile checking your error code see what the problem is and see where you can fix it
169.2 -> We can see it's just a simple fix by changing the icon name in the future
172.72 -> It might be a little bit more complex
174.08 -> But by reading the error messages we can get a clear understanding of what the problem is
177.92 -> So I hope you found this quick video helpful. If you did hit the like button as always
