Editing text in games

rownn

Hi everybody,

I’m not sure if the title of the topic is clear. I’d like to make it possible to write and edit a text while a game is running. So I tried to use an UI text field and I saw that it is very close to what I’m looking for, but the behavior differs to usual text editing in other applications. The text field seems to be just one line without line breaks, I cannot see the curser position and selecting parts of input is possible but not visible. So is there a way to get an text editor field into games? I don’t want it to be somehow fancy. I want it just as usual.

Hope someone of you can give me a hint, happy eastern to those who are going to celebrate it and greetings to the other

:) rownn

You might want to check the TextView. There is also a post about “search and selecting“ in this forum (i saw it a while ago).

select

@rownn hello can ou give an example of ht your looking or exctly? from what you have provided you are correct in the TextField not being wht you need. TextView sounds more like ht your looking for.

You sy its a game so i assume your using scene module. its more work but using EffectNode , SpriteNode and LabelNode together ndyou cn creat whtever outcome ou are looking for

@rownn heres a quick Example for TextView ↴


from scene import *

class GameLoop (Scene):
	def setup(self):
		self.background_color='#ceb763'

	def did_change_size(self):
		pass
	
	def update(self):
		pass
	
	def touch_began(self, touch):
		pass
	
	def touch_moved(self, touch):
		pass
	
	def touch_ended(self, touch):
		pass

class GUI(ui.View):
	def __init__(self, *args, **kwargs):
		self.frame=(0, 0, w, h)
		self.game_loop=SceneView(
			scene=GameLoop(), frame=(10, h/2, w-20, h/100*50-10))
		self.add_subview(self.game_loop)
		self.tv=ui.TextView(frame=(10, 10, w-20, h/100*50-20))
		self.tv.delegate=self
		self.add_subview(self.tv)
		
	def textview_should_begin_editing(self, textview):
        return True
        
    def textview_did_begin_editing(self, textview):
        pass
        
    def textview_did_end_editing(self, textview):
        pass
        
    def textview_should_change(self, textview, range, replacement):
        return True
        
    def textview_did_change(self, textview):
        pass
        
    def textview_did_change_selection(self, textview):
        pass
if __name__ == '__main__':
	GUI().present('fullscreen')

Example split screen SceneView on botom nd TextView on top. They can overlap but they will not share touch event. For example If SceneView is deper than TextView and you touch an area they share (overlapping) only TextView recieves Touch Event.

@rownn, years and years ago I wrote this thing called MarkdownView which lets you have nice-looking text views that are in-place editable in markdown. It is probably in need of a Python 3 overhaul.

Another relatively simple option is to have a WebView that has a single editable div in it – but you need some menus or text replacement in place to start lists etc. I have a working Evernote client based on this approach, but it does need quite a bit of Javascript.

Hey guys,

I’m somehow overwhelmed. Thanks for all your replies and hints. I have to go through your tips first and I will be back soon.

Thanks again

Hey,
textView seems to be exectly what I looked for, amazing, thank you guys. @stephen thx for sharing the snippet. Took a look in the textView before, but I guess I will need a lot more snippets to feel a bit familiar with pythonista.

@mikael y tried your MarkdownView a while back and i couldn't get it o work . i wa les experienced with python and ui at the time so im not sure if it was user eror or if it needed update

Hi guys,

I feel a bit ashamed about my topic, because everything I needed to know is well descripted in the documentation. :/ But as I said I‘m not that familiar with pythonista yet, but I have learned alot in the last few days. Thanks again!

AND: pythonista rocks!

@rownn the docs were hard for myself to follow at first to even with C# experience. not a problem 🤓😎
