kandi X-RAY | snake Summary
The core of the project can be found within ./engine, with the adapters occupying the sibling directories. This models allows for arbitrary clients to interface with the engine. web - The web adapter implements a websocket interface on top of the engine. This spins up a server which runs a game per connection. Each connection is isolated, and cannot affect the game of any other connection. The adapter provides a set of messages to provide game input, and send state messages back to the client. The entire simulation occurs on the server, with the client only being required to implement the render and input relay logic, an example in <100 lines can be found here. This however does leave you at the mercy of the latency between the client and server. Anecdotal testing finds an acceptable range of up to ~150ms. validator - The validator adapter provides the ability for the engine to confirm a series of "ticks" given to it by a client. A tick represents a single state change within the game (the snake moving a single position in any direction). The adapter is built to receive a description of the start of a game, which it generates fruit for, signs, and returns. This signature must be returned in all further requests. The client then records the ticks taken to move to the piece of randomly generated fruit, and sends this along with other information and the signature back to the server for validation. The benefit of this approach is that the server remains stateless regardless of how many games are being played simultaneously. term-snake - Proof of concept in the terminal. Not a particularly useful adapter, but a good example of the versatility of the adapters on top of the engine.

QUESTION
I'm creating a machine-learning program to recognize images that are shown on webcam. I've used Google Teachable Machine to generate the model and it works fine.
The matter I'm having issues with is printing the results of a prediction array, when an element of this array achieves a certain value (if it's equal to or more than 0.9 for an element, print a specific message).
Let's say when element prediction[0] >= 0.9 I want to execute print("Up") as it recognizes the image of an arrow facing up or if element prediction[1] >= 0.9 I'd do a print("Down") etc.
But when I try do that using the if statement I am presented with a

Answered 2021-Jun-10 at 17:11The problem is that your prediction has an "incorrect" shape when you're trying to check for each of the values. The following illustrates this:

I am trying to build a strictly typed factory for my TS project and having issues figuring out if it is possible to automatically infer a schema from the passed argument.
...ANSWER
Answered 2021-Jun-08 at 15:23You should narrow References type instead of declaring it explicitly:

typedef struct TILE{
char p[4];
char ladder,snake;
char end;
int boardLoc;
struct TILE *pointer;
}tile;
tile *myTable = (tile*) calloc(row*col,sizeof(tile));
//This code works (using brackets [])
(myTable+90)->p[0] = 'a';
(myTable+90)->p[1] = 'b';
(myTable+90)->p[2] = 'c';
(myTable+90)->p[3] = 'd';
//This code does not work (using pointer arithmetic)
*(myTable+90).(*(p+0)) = 'a';
*(myTable+90).(*(p+1)) = 'b';
*(myTable+90).(*(p+2)) = 'c';
*(myTable+90).(*(p+3)) = 'd';
//This code does not work either (arrow operator and pointer arithmetic to access array)
(myTable+90)->(*(p+0)) = 'a';
(myTable+90)->(*(p+1)) = 'b';
(myTable+90)->(*(p+2)) = 'c';

QUESTION
I'm doing a snake game in a way of attaching turtles together and move each of them individually each time. Let's say we have a white snake on a black screen which consists of multiple adjacent 'square' turtles. If the snake move and hit the wall, it should be removed. So what's the best way to do it? Loop through all segments and use hideturtle() to hide each turtle element? Or simply move every segment out of the screen.
...ANSWER
Answered 2021-Jun-06 at 07:35The simplest way would be when the brick moves and hits the wall it has each segment be set to invisible. These can all be cleaned up or removed at an intermediary screen like a play again/etc

QUESTION
I want to save all the scores of my game (a simple snake game) to a file and then read all the scores. Problem is, i dont know how to save them without knowing how many there will be.
...ANSWER
Answered 2021-Jun-01 at 20:11From what you describe, what you want is:
- open the file for writing
- write to the file
- be done with writing to the file
- open the file for reading
- read from the file
- be done with reading form the file.
So your code should reflect that sequence!
The key point is that you are ever only reading or writing from the file at any given moment, so the ifstream and the ofstream should never exist at the same time!
There's a few ways to go about that, but the simplest is to use functions to isolate them. Here's what that would look like in your case:

i made a linked list and filled it with 4 "#" characters, i wanted to print them in screen with the ncurses library because i'm trying to make a snake game but idk why it doesn't print, here's the code:
...ANSWER
Answered 2021-May-29 at 07:48Your programs have several bugs, I have fixed them. The most serious is that your code cannot be compiled in C++. If it's intended to build it under C++, you need to fix the compile errors at first.
newPiece = malloc(sizeof(struct snake));, need a convertion here:newPiece = (snake *)malloc(sizeof(struct snake));, generally it's not recomended to usemallocin c++, it's more naturally to usenewfirst = addNewPiece("#");Pass string literal ascharargument, need to pass a character here.mvwprintw(win, y, x, t);, you have misunderstand the API, should be fixed asmvwprintw(win, y, x, "%c", t->piece);, you need to see the document before use a library API to see what types of arguments it expectsYou forget to refresh the screen after printing the screen!
You haven't increment the index in for loop, it's an infinite loop.
Your code is somewhat c style, if you are trying to write with C++, it needs to be refactored, some suggestions:
- use
std::vectorto store the snake body, then we don't need to manage the memory by hand. And avoid the error-prone linked list processing. Then most part of your code can be simplified. - Use a logging library and print logs to help to debug
The fixed code should work, I get a vertical snake on my console.
