This is a simple snakes implementation using python outlined in [1] with help from [2]. The example file implements the example outlined in [2]. Python library dependencies are numpy, scipy, and matplotlib. After cloning the repository, you should just be able to run. to see the example problem. After that, run. to see a slightly more complicated shape. [1]: Snakes: Active contour models. M Kass, A Witkin, D Terzopoulos - International journal of computer vision, 1988.

QUESTION
Task: You are given the noises made by different animals that you can hear in the dark, evaluate each noise to determine which animal it belongs to. Lions say 'Grr', Tigers say 'Rawr', Snakes say 'Ssss', and Birds say 'Chirp'.
Input Format: A string that represent the noises that you hear with a space between them.
Output Format: A string that includes each animal that you hear with a space after each one. (animals can repeat)
Sample Input: Rawr Chirp Ssss
Sample Output: Tiger Bird Snake
This is what I have tried:
...ANSWER
Answered 2021-Apr-03 at 01:44There are a couple of issues with your approach.
- Reading an entire line and trying to split it is more difficult than just reading each sound one at a time and outputting the animal. That also helps with the next issue since you don't need the array if you read word by word.
- Variable length arrays, like
string sounds_filtered[sounds.size() - 1];
are not standard C++ and will not work on all compilers. If you need something like this consider astd::vector
instead. cout << sounds_filtered;
won't work, as you've noticed. You would need a loop to print each item in the array.using namespace std;
may save you a bit of typing and seem more convenient but it can lead to difficult to diagnose problems when you have a name conflict. You can read more about that here if you like: Why is "using namespace std;" considered bad practice?
Here is an example of reading each sound one at a time and outputting the animal. I used a std::map
to simplify matching the sound to the animal. You could use parallel arrays for this as you do in your example but it does make looking things up more difficult. If you do stick with the arrays I'd advise putting the lookup in a function to make the main loop easier to read.
QUESTION
I have programmed a simple clone of Slither.io in python using pygame and sockets and I have three problems:
- When I play the game alone on my laptop the game is choppy. Every ten seconds my game get stuck for a while (one milisecond) and then continue. It's not a big problem but it's annoying.
- When I play on two computers in my local network, I see the other player (the other snake) is also choppy.
- The strangest problem is when I run my server on my main laptop and then run the game on my second laptop the game starts and after few seconds crash. Debugger on client says that pickle data was truncated while receiving data from the server. But when I run the server program on my second laptop and the game on my main laptop everything is OK. Why?
I tried:
Problem 1. change FPS on the client and time.sleep on the server
Problem 2. change time.sleep on the server
Problem 3. change the input value of recv() method
Server code:
...ANSWER
Answered 2021-Mar-15 at 17:49Your third problem (truncated pickle data) is because you are using TCP, and you are unpickling whatever recv
returns. You might be thinking that whenever you send
something, and the receiver calls recv
, returns the exact same thing, but actually it doesn't. TCP splits your data up into packets, so the receiver might not receive all the data at the same time.
For example, if you send "abcdefgh" and then separately send "ijkl", it's allowed for the first receive to return "abcd" and the second to return "efghijkl". Or the first one could return "ab" and the second one could return "cde" and the third one could return "fghijkl", or so on.
You have to design a way for the receiver to know when to stop receiving. For example, if you sent "8abcdefgh" and then "4ijkl", the receiver could get "8abcdefgh4ij", and then it knows "8abcdefgh" is one "send" (because it starts with 8 and then 8 more bytes) and it knows the "4ij" is the beginning of the next "send" but it's not the whole thing (because it starts with 4 but there aren't 4 more bytes).
Another way is to send a special character like a newline (enter key) after each message. This probably doesn't work with pickles because pickles can have newlines in them. But you could choose another byte that pickles don't have, like 0xFF. Then the receiver knows to keep on receiving until it sees the byte 0xFF.

QUESTION
While learning pygame, I created a Snakes game. I have a high_score.txt file which stores the high score of player. When the player breaks a score record, his/her new record is written in this txt file with python's open() function. The script runs fine, there's no problem at all.
Now, I converted this script into an executable using pyinstaller. I didn't use one-file mode. The executable also runs fine. Then, I used INNO SETUP COMPILER to convert my executable into a setup file. After I run this setup, the files required to run exe are stored in a separate Snakes folder in Program Files folder in my computer's C Drive.
The problem now begins. When I run my newly installed game, it starts fine. But when I start playing it, whenever I eat an apple (the food of snake), the error pop ups: Unable to run script main. After some debugging, I came to know that this error is coming because python is unable to rewrite the high_score.txt file to store the new high score, because the writing access is denied in Program Files folder. If I run my game as an administrator, then it runs fine. But I want this game to run properly without administrative access. I have researched it about on the Internet very much but nothing could help me. Is there any way to achieve this?

Answered 2021-Mar-11 at 17:09You should store this in the appropriate user directory, not the install location. Use Path.home

QUESTION
I know this sounds stupid and I'm propably very late to the party but here's the thing I want to program an gesture recogniction application (in the likes of this Hand detection or this actual finger detection) for the Xbox 360 Kinect. SDK (version 1.8) is found, installed and works, preliminary research is done - I only forgot to look in which language to write the code. The link from the SDK to the documentation would be the first thing to do but is a dead end, unfortunately.
From the provided examples it seems either to be C++ or C# although some old posts also claim Java. My question is: Is there a documentation not tied to the SDK and which pitfall are there in regard to developing in this specific case under C++/C#/Java? A post from 2011 barely covers the beginning.
Addendum: On further looking I was prompted for the Samples site from the developer toolkit - which can be reached, yet all listed and linked examples are dead ends too.
Addendum: For reference I userd this instruction - ultimately proving futile.
Found an version of NiTE here
...ANSWER
Answered 2021-Jan-19 at 22:29I've provided this answer in the past.
Personally I've used the Xbox360 sensor with OpenNI the most (because it's cross platform). Also the NITE middleware on alongside OpenNI provides some basic hand detection and even gesture detection (swipes, circle gesture, "button" push, etc.).
While OpenNI is opensource, NITE isn't so you'd be limited to what they provide.
The links you've shared use OpenCV. You can install OpenNI and compile OpenCV from source with OpenNI support. Alternatively, you can manually wrap the OpenNI frame data into an OpenCV cv::Mat
and carry on with the OpenCV operations from there.
Here's a basic example that uses OpenNI to get the depth data and passes that to OpenCV:

Install snakes
You can use snakes like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
