            Now Here is my solution to print similar values in console. I assume that in Sheet2, all names are in this format:
            last_name, first_name

            How to set the saturation level of an entire color channel in Unity
            Asked 2021-Dec-09 at 19:49

            I would like to set the saturation of an entire color channel in my main camera. The closest option that I've found was the Hue vs. Sat(uration) Grading Curve. In the background of the scene is a palm tree that is colored teal. I want the green level of the tree to still show. Same with the top of the grass in the foreground, It's closer to yellow than green, but I'd still want to see the little bit of green value that it has.

            I have been searching the Unity documentation and the asset store for a possible 3rd party shader for weeks, but have come up empty handed. My current result is the best I could come up with, any help would be greatly appreciated. Thank you

            SOLVED -by check-marked answer. Just wanted to share what the results look like for anyone in the future who stumbles across this issue. Compare the above screenshot, where the palm tree in the background and the grass tops in the foreground are just black and white, to the after screenshot below. Full control in the scene of RGB saturation!

            My best guess would be to use a custom shader or camera FX that would gives you control over each channel.

            Hope that helped ;)

            Conditional backfill of Pandas columns, another variation
            Asked 2021-Dec-04 at 16:30

            I have the following Dataframe:

            Track FGrating HorseId Last FGrating at Happy Valley Grass Happy Valley grass 97 22609 Happy Valley grass 106 22609 97 Happy Valley grass 104 22609 106 Happy Valley grass 102 22609 104 Happy Valley grass 95 22609 102 Sha Tin grass 108 22609 Sha Tin grass 104 22609 Happy Valley grass 107 22609 95 Sha Tin grass 102 22609 Happy Valley grass 108 22609 107

            I need to fill the empty cells of the rightmost column according to these two rules:

            1. If the horse didn't race on the particular track yet (Happy Valley grass, in this example), then the value to be filled is 0;
            2. Between two races at the particular track (Happy Valley grass, in this example), the value to be filled is the last FGrating on the track in question (the two consecutive rows with Sha Tin grass will get the value 95 and the third one will get 107).

            The end result will be like this:

            Track FGrating HorseId Last FGrating at Happy Valley Grass Happy Valley grass 97 22609 0 (rule 1) Happy Valley grass 106 22609 97 Happy Valley grass 104 22609 106 Happy Valley grass 102 22609 104 Happy Valley grass 95 22609 102 Sha Tin grass 108 22609 95 (rule 2) Sha Tin grass 104 22609 95 (rule 2) Happy Valley grass 107 22609 95 Sha Tin grass 102 22609 107 (rule 2) Happy Valley grass 108 22609 107

            I need this for every HorseId on the Dataframe

            How to use noise to generate 2d tile based terrain?
            Asked 2021-Nov-01 at 06:51

            I'm trying to make a 2d tile based game in pygame. I've implemented an algorithm that converts the characters in a 2d array into the tiles, with the posiiton derived from the row and column of the character in the array. Eg-

            The Array- (manually typed "terrain")

            The game- (The g's and s' in the array correspond to grass and stone respectively. )

            Here

            Now, i want to generate the "G"'s in the list with some kind of noise, so I can further implement it to generate infinitely. The few documentations I've seen on this were really hard to understand :(. So how do I use noise to autogenerate the "G"'s in the terrain? Thanks!

            I would suggest to generate your world column by column. As I presume this is some kind of platform left to right game, this would make more sense.

            Below is a small snippet to show you a possible simple logic to do so. There is a fixed number of S, G can vary +1/0/-1 at each new step. Finally the last line is to convert to your line format to display:

            React - filtering items from an array in any order
            Asked 2021-Oct-03 at 08:12

            I'm sorry that this question has been asked in a similar fashion. I've read through a lot of similar threads but just don't know enough to apply it to my little project. I'm very new to React so I would appreciate any help!

            Getting to it, I'm making a pokemon game where someone can hit click buttons to filter down a JSON list of pokemon. They can go by type,weaknessess,etc.

            But I'm a little confused in keeping a 'global array' if that's the right word. It may be something I don't understand with React's useState.

            Problem

            You are facing this problem because you try to set the state of the list in an "imperative" manner, but React is meant to be used more "declarative". That means, what you try here is like:

            • "if I click the button, change the list to contain the items that contain 'Grass'",

            but how you should use React is:

            • "if I click the button, then the state of my component should be that the list only contains items with 'grass'"

            That might sound like the same, but there is a subtle difference. React is good in changing a state dependent on some other state. You might say "but that's what I'm trying to do, changing the state of the list", but then you have tell the full story

            • "if I click the button, and the list is not filtered already, and maybe contains the items X, then change the list to contain the items that contain 'Grass', unless ..."

            This becomes quite complicated, especially comparing contents of lists and components.

            Solution

            There are different solutions to your problem, but what you should do is basically something like:

            • set the component state to describe what you want
            • have other parts of your program (and React) take care to give you a the list dependent on this description

            Parse geojson files with C
            Asked 2021-Sep-08 at 11:28

            I can't find any simple C source file or library to parse geojson files (implementing rfc7946 standard).

            Maybe such parsers exist in projects like GRASS or GDAL? But I still have a little trouble navigating the world of C libraries.

            Some tracks ?

            ANSWER

            Answered 2021-Aug-31 at 23:47

            GeoJSON is in JSON format, so you can use JSON parsers. There are several out there:

            https://github.com/search?l=C&q=json+parser&type=Repositories

            You should add checks and other stuff yourself.

            If you need a certain representation of data, you can write it yourself. Mapbox wrote a C++ version of GeoJSON parser for converting GeoJSON into geometry.hpp representation based on RapidJSON in less than 1k lines of code.

            A standard-compliant (RFC 7946) implementation of GeoJSON in C can be found inside SpatiaLite, but may be it's easier for you to use typical JSON parsers instead. You can take a look in virtualgeojson.c if you want to use this library.
