c – How should I store loaded world pieces in RAM (my game is similar to minecraft)?

I'm trying to replicate a C-block loading system for my own minecraft type game, although I do not know how. Once pieces are loaded, are they placed in a table or are there multiple variables for each loaded song? In my game, once I load songs with the help of fread, what should I use to store them. My problem for a two-dimensional array for storing pieces is that the loaded pieces can be separated and not start from scratch. Are there any suggestions for storing loaded songs?

I have a code snippet, only so you do not scream at me not to include the code:

                char ChunkFilePath[strlen(CurrentWorld)+32];
sprintf (ChunkFilePath, "% s / ChunkData /% ld% ld", CurrentWorld, X, Z);
FILE * ChunkFile;
if ((ChunkFile = fopen (ChunkFilePath, "r")))) {
// the song file exists, read the song file at ???
}
if ((ChunkFile = fopen (ChunkFilePath, "w")) == NULL) {
fputs ("Error loading block (file not found)", stderr);
return;
}
/ * The song does not exist, but all other errors would have been intercepted.
at this point, in order to generate chunk, write the results generated to ??? * /

Note: The game I am trying to create is for personal, noncommercial purposes only.

hash algorithm for very similar images

I am looking for an image hashing algorithm (for the moment, I am thinking of a perceptual hashing) which is able to preserve the details a little more than the usual hash algorithms. The images that I must distinguish are quite similar at first and the details have to be taken into account. I do not really want to reduce them. I need to know if a given image matches an image already in a database, but I want it to at least resist trimming and rotation (cropped / rotated images should give the same or near result An extra bonus would be if it's also resistant to changing a few pixels (with a threshold, of course.). My fear with the usual perception hashes is that they reduce the image so much, and the images I have all seems too similar. Thank you!

launchd – How to display the status of the service (for example, if it is running) in a format similar to `systemctl` in Linux with macOS` launchctl`?

You can do this by running the command:

launch list

In the first column of the output, you will find the PID. If there is a number, the service is running – if it is listed as "-", it is not in progress. # 39; execution.

Likewise, you can check a single daemon like this:

launch list 

this will give an output with various information – one of the lines looking like this:

"PID" = 310;

it means that the program is running and that the process ID is 310. If there is no "PID" line, the daemon is not not running.

8 – Is there a variable printer similar to dd () that can be used in a pretreatment?

Often, when I run a hook_preprocess_hook, I start by printing the $ vars object. I can do it with dpm (), ing, dsm (), kint (), and so on. The problem is that all these functions print $ vars more extensively and put my computer on my knees. dd () works incredibly well in pretty much everything I do in drupal, but for some reason, dd () is content with WSOD in a pretreatment.

Is there anything like dd () (that is, that prints tables / objects in a small way) that can be used in a preprocessing?

I know XDebug, but I wonder if there is something as simple as installing the module -> using a function like devel / dd () works in other Drupal applications.

dnd 5e – Can we use wonderful pigments to enlarge the surface of a portable hole or a similar extradimensional space?

The description of the magical article on the wonderful pigments of Nolzur reads as follows:

When you finish the painting, the object or the relief represented becomes a real object and not a magic one. Thus, painting a door on a wall creates a door that can be opened to anything beyond. Painting a pit on a floor creates a real pit whose depth is relative to the total area of ​​the objects you create.

The description of the Magic Hole Portable article states:

the portable hole creates an extradimensional hole 10 feet deep. The cylindrical space in the hole exists on another plane

Can we use wonderful pigments to expand the surface of a portable hole (or a similar extradimensional space, such as the area of ​​a Demiplane spell, a holding bag, a Haversack practice of Heward, etc.)?
