You were on the right way. But you mangled some of your vars.

Try:

Use pygame.time.Clock to control the frames per second and thus the game speed.

The method tick() of a pygame.time.Clock object, delays the game in that way, that every iteration of the loop consumes the same period of time. See pygame.time.Clock.tick():

This method should be called once per frame.

That means that the loop:

Unity font management operates on textures to render characters, and needs to be informed what characters to load in order to add them to a font texture, before you can use them while rendering text. Unless you request loading characters outside your example, having characters that exist in a font but don't have info available are due to not having them loaded into a font texture when you query font for their info.

Font.HasCharacter checks if a font you use has character defined - if it returns false, that character doesn't exist in a font and can't be loaded to be used. Example would be checking a non-latin symbol in font that covers only latin characters. Font.HasCharacter returning true means you can load that character to a font texture.

Font.GetCharacterInfo get information about a symbol from currently loaded font texture - so there is a possibility that loaded font may have a character available, but not loaded; this will cause Font.GetCharacterInfo to return false and make character not render if your render text manually. To work around that, you need to request Unity to load characters you will need by using RequestCharactersInTexture - documentation also contains an example on how to handle manual text rendering including font texture updates. Until you have a character loaded, you won't be able to get its font info, since it doesn't exist in currently used Font texture. When calling RequestCharactersInTexture, pass all characters that occur in your text regardless if they're loaded or not - that way you make sure Font won't unload a character that was previously loaded when loading new ones.

When working on a solution to determine where to put line breaks, you may need to take kerning into account - depending on surrounding characters, font may want to use different distance between characters or sometimes even use different glyphs. If you render text manually, make sure to have consistent handling of kerning between calculating linebreaks - no kerning is a good strategy, as long as font you're using doesn't depend heavily on kerning. If you want to support kerning, you should work on substrings instead of single characters and try to find best points of introducing line break for a whole line - width of a line may be different from sum of all character widths that occur in said line.

The issue is that in the Matcher, by default each dictionary in the pattern corresponds to exactly one token. So your regex doesn't match any number of characters, it matches any one token, which isn't what you want.

To get what you want, you can use the OP value to specify that you want to match any number of tokens. See the operators or quantifiers section in the docs.

However, given your problem, you probably want to actually use the Dependency Matcher instead, so I rewrote your code to use that as well. Try this:

One of the best things you could do is a function:

You can use preg_match_all for this. So if your input string is $str, the $result can be achieved as follows:
