I rewrote your code with some better ways to create table. My idea was to pick out the buttons that fell onto a range of type and then loop through those buttons and change its color to those type.

It is being called, as you've realized. When you define the dict, the call is evaluated and its result is inserted into the dict under 'custom', so in that example, 'custom': 1.0. To avoid the call, make it a function instead.

Now that raises the question of how to have mixed types in a dict (floats and functions) and special-casing the functions. One way to get around that is to have two separate dicts: one with floats and a fallback one with functions. For example:

As per pandas documentation, pd.read_csv, you can provide sep as only string and string like r"" is usually used for Raw string.

What I would recommend is first loop through file and replace all delimiter to a common delimiter and then feed file to pandas read_csv.

Apparently, Above answer is not true. jjramsey from comment below has mentioned it perfectly how it's wrong.

In the Pandas documentation for read_csv(), it says, "separators longer than 1 character and different from \s+ will be interpreted as regular expressions." So, no separators are not always fixed strings. Also, r is a perfectly good prefix for strings used for regular expressions, since it avoids having to escape backslashes.

So, since you've already figured it out yourself, here is the detailed explanation.

find is a function ( or what fancy developers like to say a higher order function ) available for javascript arrays that accepts a function which must return a boolean value i.e., either true or false.

---Quick detour---

A function which must return a boolean value is called a predicate, and this is exactly what's available in the IDE hints if you hover over find

---Detour end---

It accepts multiple parameters, with only the predicate being mandatory, and the rest are optional, i'm skipping all the optional ones, so that's your homework, read the docs or the articles at the end of this answer.

As you can read in the hint itself, it will call the predicate, once for each element in the array, until it can find one which will return true & return the value of the element, undefined otherwise.

Which means : that the first parameter in the predicate is going to be your object and the same predicate will be executed on it for all the elements.

Now observe your solution carefully:

find( savedChar => savedChar.id === character.id )

savedChar is one of the objects in the array, and it needs to be compared with the character object, and id which is the short form of identity will always find it accurately.

Finally, quick answers to your problems.

1. Use find to see if the character is already available, if yes, simply don't add it in your collection.

2. This will require you to change your render logic, find if the object is in the favorites and render it differently.

3. just like find, there is a method called reduce, why don't you give it a shot? but that might be a little difficult, so you can use a simple for loop instead.

4. find(savedChar => savedChar["good-or-bad"]) <- what would this result? figure it out.

For the first error You are using an outdated version of Java, you have to upgrade your Java version from 1.8 to 1.16.

Then, for the second error java.nio.file.FileSystemException :

Stop all running gradle daemons thanks to gradlew --stop command.

A method need to return something every time (return null will work too), so when the return is in if statement, it may not enter that if statement on all of the loop's iterations therefore not return anything, so you need to have another return either in else statement, or outside of the if statement.

The uniform particle is of type vec2[30]. An uniform array can needs to be set with SetShaderValueV instead of SetShaderValue:

SetShaderValue(shader, particleLoc, particles, SHADER_UNIFORM_VEC2);
