@BapeHiks

im runing iPadOS 13.4 and i also cannot set the widget from settings. but i have no problem setting the widget using appex.set_widget_view().

i hope this helps you out until the bug is corrected!

Here is a little game to help new develpoers to game design get started. there is a tutorial in exmples but its very minimal and doesnt give examples of diferent styles of writing. this currently is not a tutorial. and it is not flooded with comments so that its easier to follow the code. any questions are more than welcomeand i will add annotations as needed.

the game itssrlf is not perfect and does have bugs that pop up here and there. this is mainly due to using multiple styles at once creating small conflicts but the game does play and should be easy to expand nd add aditional components. i tried to leave it in a way that made it to whoever was using it could add functionality to help learn and understand game development. all images are builtin and script should run without any dependancies as long as its ran within Pythonista.

Enjoy
Stephen, Frey

Script

@Karina @Drizzel here is a demo for action timing. i intended to have much more informative and visually attractive version and ill improve it in time but for noe you can see a visual difference between each interpolation.

note: this is formated for ipad only. future versions will have formatting for other devices. i appoligise.

heres is example of using brush like objects with scrolling nd random (not too random) spacing. if you have ny questions please ask!

@elkrause helo. you can try this

Extended Example Script for Pythonista Keyboard

Everything is still the Same Concept. additions and changes are as follows...

• Multi-tier menu for Unicode Grouping.
• Resizing buttons to make best use of screen width while still providing
  enoigh area for Text.
• For Performance different catagories of Unicode are placed in separate
  .txt files.
• Larger selection of Characters and Symbols.
• ⏎ button to send user back to menu without having to reload Script.
• Easily add more Files and Unicode without having to touch the code itself.

Adding To Collection

Scripts ↴

• To add more Script type retrieve the chart from source
• open Scripts.txt. on the first available empty line and paste unicode.
• Keeping each script within a single line separating name from code with :
script name:ABCDEFG...
• once file saved new script will be ready to use.

Emoji and Symbold ↴

• inside respective file 💪 ⟾ Emoji.txt and ♳✯✟ ⟾ Misc.txt place each
  grouping together in one line.
• And thats all! the first item in the line will be the display button Image.

Premade Smilies ↴

• Inside Faces.txt place each face on a single line.
• Once file saves Custom Faces will be Available!

For seamless Use, change Script file name to Special Characters.py and
place inside Examples/Keyboard/ replacing original script. This way will use
new Version instead without the need to Setup inside Pythonista settings.

Adding .txt files

• place new file inside Locak Directory and add to new line the file name inside Options.txt
• new file will be available in home menu on next launch.

—STEPHEN FREY

Included are two files for offline Resource for Unicode. Files are to large to open inside Pythonists and Editorial.

Attribution goes to OMZ, devloper of Pythonista
for providing IDE as well as the tools and original script for this Module!

Layout

pythonista Docs

def layout(self):
        # This will be called when a view is resized. You should typically set the
        # frames of the view's subviews here, if your layout requirements cannot
        # be fulfilled with the standard auto-resizing (flex) attribute.
        pass

often used to signal when screen orientation has changed.

also in scene Module

def did_change_size(self):
	pass

After many hours of thought and going over my cose a few times i fiund that since
I already released the Game Example Space Escape, its nearly pointless to do
a tutorial series on the same project.. That said i will be closing this one here
and i will create a new one.

PYTHON RPG

Python RPG will cover at more aspects of game development.

• Sprite Animations
• Inventory System
• NPC Economics
• Combat System

and much more..

This new series will be done in sections due to the amount of code and testing we will
need. i will provide sprite sheets to help follow along, though i do encourage using your
own assets to help motivate yourself to push on. game development can get pretty stressfull
and even make you feel like its too hard. but keep pushing along and ALWAYS ask a question
if you have one!

Keep note that i will be writing this on my own and do have a life outside Python, at least i
like to think i do... so there might be gaps in time between sections and chapters. 🤓

Lets get started!

@jackattack said:

Also the only bit I didn’t really understand was when you set up the button class you used init, but then you did spritenode.init what is this for?

when you subclass an object that has __init__ paramiters you must either call the Parent class __init__ as i did here or you can use super(). if you do not call the parent's __init__ then the new object will not inherit the dirived.

@jackattack said:

I’ve learnt so much reading your code, love the way you’ve done so many things, spent ages going through it all. Could you give me any insight into the order you went about writing it?

I usually start with utility classes. in my Example game this would be stuff like Screen() and EventManager(), then visual testing. at this point i woud start my ButtonNode() and Animations().. now i create my Player(), GUI() and o on. the order on the script itself doesnt matter with Object Orientated Programing (OOP) just remember the Interpreter exec the scripts top down. so in order to Dirive from from Class A it must exist before Class B.

@jackattack said:

Wow this works perfectly thank you so much, I’m going to take some time to study it and try to learn how to recreate it with some other effects. Thanks for taking the time out 😌

Not a problem at all! 🥂💯 i enjoy helping others if you have any equestions please dont hesitate!;

@etalamo

You can use editor module to get selected text range and then split the lines into a list. last you should be able to iterate the list and use exec to run each line. Alterativly you could create a temp script at run time then write the selected code to that script then run the scriot. just make ure to save the stream and close it.

if you need an example i can write one up for you but this should get you in the right direction.

@Bumbo-Cactoni

I am too!! Lol

@jackattack

here is my script example. sorry it took a while lol. its not very clean but i think it should be easy to follow. let me know if you have any questions. you should benable to use thenSprite class to create other objects and as you will see this approach doesnt use the update method at all or depend on position.

If your running an example script chances are it is executing and doing some function but has no visual presentation and exec in less then a second. if you use scene, ui, while or for loop you can maintain the program and using scene and/or ui modules to present visual presence.

post your code and that will help us help you. use MarkDown to format the code. before and after place ```

Sure can do, what format can I post it on here?

You will have to upload somewhere then hyperlink it. I personally use Imgur

@jackattack said:

I basically just cropped one from online to make it easier to work with

no problem its just to help replicate the same execution you have 😎

@jackattack
Any chance we can get the sprite sheet your using?

@jackattack

Also can you post the code you are using just in case it's just a small mishap? Make sure to put the code inside two ``` so that it is formatted properly

Checkout the *** COMPOSE *** on top right when your writing a post 😀

Hey buddy! I have a "full" example game for new developers to take a look at here on the forums. He game doesn't use sprite sheets but it should give you a good understanding of the animation system 😀

While you look this over I will prepare an example for your specific use and give some comment explanation of what's going on! I got 4 kiddos so just bare with me lol I'm not as fast as I used to be buddy!

Here Is the post for the example Game 😉
