QUESTION
I want Python to kind of ignore a statement that is unlikely to be called in a function that is often called.
I do not have a formal education in programming, so please excuse my lackluster ability to desribe things. I will try to explain the concept by example.
Say I am writing a video game, first-person shooter, drawing 60 frames per second.
In the settings menu, the user can select whether or not to display the name of other players above their head. If they disable this, I store this value as showplayernames = False.
Then in my drawing function that outputs the graphics I have:
...ANSWER
Answered 2022-Apr-07 at 15:38not an game designer, but here is my voice. You could store settings inside json file next to you python, but then you need to cover reading, getting right values etc.
You could use Environment variables to store value but that would end up using still "if" in the code.
Game designers use triggers and events to get things done, and on the lowest level I would assume those things also use if's.
system-wide-settings will in the end be used with if's
You could use overwrites based on event/trigger and use "same" draw function in both times but that only complicates code, and we all know to "keep it simple".
Sorry if this is not the answer you were looking for.
QUESTION
I was trying to find a way to error/style correct a non-standard custom menu file from a decade old video game that I was working on in Notepad++ and this was the best I could come up with.
The below returns any curly brackets that aren't followed by an EOL character or are preceded by anything other than line start and 1-4 tabs, it works fine but seems like it could be a lot more elegant. Any returned brackets are incorrect unless they're the first or last in the file. More tabs are technically okay highly unlikely.
...ANSWER
Answered 2022-Mar-18 at 16:55I want to start by saying that regex is 100% the wrong tool for this, you want a custom parser to handle both validating your file and parsing it into a model you can then use.
However, with the limitations imposed by your question, the following should do it:
QUESTION
so I'm trying to create an online game using Babylon.js but have run into a problem thats got me a little stumped so hoping someone here would be willing to help me out. Please bear with me on this one, i'm a complete newbie with babylon as i've only every worked with THREE.js. Right now my game consists of a scene compromising of multiple meshes with multiple users represented as avatars (created from basic circle geometry for the moment) loaded into an environment. What I want to do is highlight the outline of these avatars ONLY when they are occluded by any other object, meaning that when they are not occluded they look normal with no highlight but when behind an object their highlighted silhouette can be seen by others (including yourself as you can see your own avatar). This is very akin to effects used in many other video games (see example below).
Thus far, based on some googling and forum browsing (Babylonjs outline through walls & https://forum.babylonjs.com/t/highlight-through-objects/8002/4) I've figured out how to highlight the outline of objects using Babylon.HighlighLayer and I know that i can render objects above others via RenderingGroups but I can't seem to figure out how to use them in conjunction to create the effect I want. The best i've managed to do is get the highlighted avatar render above everything but I need just the silhouette not the entire mesh. I'm also constrained by the fact that my scene has many meshes in it that are loaded dynamically and i'm also trying to keep things as optimal as possible. Can't afford to use very computationally expensive procedures.
Anybody know of the best way to approach this? Would greatly appreciate any advice or assistance you can provide.Thanks!
...ANSWER
Answered 2022-Feb-22 at 09:36So I asked the same question on the babylon forums which helped me to find a solution. All credit goes to the guy's that helped me out over there but just in case someone else comes across this question seeking an answer, here is a link to that forum question https://forum.babylonjs.com/t/showing-highlighted-silhouette-of-mesh-only-when-it-is-occluded/27783/7
Edit: Ok thought i'd include the two possible solutions here properly as well as their babylon playgrounds. All credit goes to roland & evgeni_popov who came up with these solutions on the forum linked above.
The first solution is easier to implement but slightly less performant than the second solution.

QUESTION
I want to extract story plots from the English Wikipedia. I'm only looking for a few (~100) and the source of the plots doesn't matter, e.g. novels, video games, etc.
I briefly tried a few things that didn't work, and need some clarification on what I'm missing and where to direct my efforts. It would be nice if I could avoid manual parsing and could get just issue a single query.
Things I tried 1. markriedl/WikiPlotsThis repo downloads the pages-articles dump, expands it using wikiextractor, then scans each article and saves the contents of each section whose title contains "plot". This is a heavy-handed method of achieving what I want, but I gave it a try and failed. I had to run wikiextractor inside Docker because there are known issues with Windows, and then wikiextractor failed because there is a problem with the --html flag.
I could probably get this working but it would take a lot of effort and there seemed like better ways.
2. WikidataI used the Wikidata SPARQL service and was able to get some queries working, but it seems like Wikidata only deals with metadata and relationships. Specifically, I was able to get novel titles but unable to get novel summaries.
3. DBpediaIn theory, DBpedia should be exactly what I want because it's "Wikipedia but structured", but they don't have nice tutorials and examples like Wikidata so I couldn't figure out how to use their SPARQL endpoint. Google wasn't much help either and seemed to imply that it's common to setup your own graph DB to query, which is beyond my scope.
4. QuarryThis is a new query service that lets you query several Wikimedia databases. Sounds promising but I was again unable to grab content.
5. PetScan & title downloadThis SO answer says I can query PetScan to get Wikipedia titles, download HTML from Wikipedia.org, then parse that HTML. This sounds like it would work, but PetScan looks intimidating and this involves HTML parsing that I want to avoid if possible.
...ANSWER
Answered 2022-Feb-18 at 21:32There's no straightforward way to do this as Wikipedia content isn't structured as you would like it to be. I'd use petscan to get a list of articles based on the category, feed them in to e.g. https://en.wikipedia.org/w/api.php?action=parse&page=The%20Hobbit&format=json&prop=sections iterate through the sections and if the 'line' attribute == 'Plot' then call e.g. https://en.wikipedia.org/w/api.php?action=parse&page=The%20Hobbit&format=json&prop=text§ion=2 where 'section' = 'number' of the section titled plot. That gives you html and I can't figure out how to just get the plain text, but you might be able to make sense of https://www.mediawiki.org/w/api.php?action=help&modules=parse

QUESTION
In a section of my code I made a row-grid for a part that displays images but when I went to insert and look at the website its not displaying in a row format but in a column and im not sure why. I thought the problem came from it being col-sm-6 but i changed it to col-sm-12 and its still not displaying it. Any reasons why?
...ANSWER
Answered 2022-Feb-04 at 08:32Changing the class row-grid to row makes it work. I don't think Bootstrap has a class called row-grid.
If you are trying to fit all the div elements into one row, just replace the col-lg-4 col-md-6 col-sm-6 and the col-lg-4 col-md-6 col-sm-12 with col

I've been having trouble with collisions in pygame. Specifically, I have a player and a list of walls, and if they collide, I'm supposed to prevent any more movement in that direction.
I've tried many guides but I can't seem to get this to work myself.
...ANSWER
Answered 2022-Jan-09 at 19:46Create the objects once before the application loop. You don't need the variables playerX and playerY at all. Use player.rect.x and player.rect.y instead.
Store the position of the player before moving it. If a collision is detected, restore player position:

In case of duplicate - i already readed other posts from stackoverflow. Most of them are asociated with Unity3D, and a lot of them are using keywords like theta/omega .. ect. I can't understand any of that stuff. Also, i have 0 knowledge of those formula symbols so i understand 0% of what i readed.
I experiment making a bot for a video game, the only thing im stuck with is how to get the needed rotation degree till i face the given cordinate. Here i made quick example of my question in programming.
