            setTimeout inside setTimeout inside a setInterval
            Asked 2021-Jun-15 at 01:25

            I'm trying to make a string that will write itself letter by letter until completing the sentence, and the speed of appearing each letter is based on an input that varies from 1 to 10. At the end of the string, it will blink for 5 seconds until that an alien will appear. My idea was to create a setInterval to add the letters and when the counter added the array size it would return the final animation of the loop with the new setInterval call, and before it was called again it had already been cleared, and called again in a recursion by setTimout callback to maintain the infinite loop. But it's not reaching setTimout, why?

            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.

            You are creating a shooting game!

            The game has two types of enemies, aliens and monsters. You shoot the aliens using your laser, and monsters using your gun. Each hit decreases the lives of the enemies by 1. The given code declares a generic Enemy class, as well as the Alien and Monster classes, with their corresponding lives count. It also defines the hit() method for the Enemy class.

            You need to do the following to complete the program:

            1. Inherit the Alien and Monster classes from the Enemy class.

            2. Complete the while loop that continuously takes the weapon of choice from user input and call the corresponding object's hit() method.

            Unity How to get get a characters width properly

            I am attempting to create a script that when a line of text would be approaching the width of the line it would attempt to wrap the text properly (ie. if the character is not '-' or ' ' then add a hyphen between letters of a word (like how word editing software does it) but when I attempt to run it a bunch of my characters disappear.

            This is the text that I am testing with, "An Aberration has a bizarre anatomy, strange abilities, an alien mindset, or any combination of the three."

            but these are the results of my test script

            "Found with info (' ','e','r','a','t','i','o','h','s','l','d')" "Found without info ('A','n','b','z','m','y',',','g','c','f','.')" "Didnt Find ()"

            and the output from compiling the text using only the characters that have available info is " erratio has a iarre aato strae ailities a alie idset or a oiatio o the three"

            Getting character info

            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.

            Determining line breaks

            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:
