QUESTION
Scenario
So, I have two scripts, "Movement" which handles all the player movement and holds a score variable for the player, this is a component that takes in the player object. Then I have another script for my moving platforms triggers which detects if the ball has passed it or not. When the trigger is activated I want to increase the Score variable in the "Movement". Problem is the error I get is...
Assets\PlatformTrigger.cs(28,23): error CS0120: An object reference is required for the non-static field, method, or property 'Movement.Score
Here are the two full scripts in their entirety

QUESTION
I am collecting data from LiDAR in real time. I created a for loop to iterate over initiating a frame, collecting the data and saving it into an array (distArray). However, I am stuck with the memory mapping part. My array takes 500 integers ==> 2000 bytes of memory .. When I try to map each array element to memory using CopyMemory(), I am getting the following error "Exception thrown at 0x5843335E (vcruntime140d.dll) in file.exe: 0xC0000005: Access violation writing location 0x007E0000." .. Any ideas on how to solve this problem?
In the code below, there are a lot of functions and header calls that are irrelevant to the question, so please don't mind them ..

I have an assignment where if I pass an array of 0s into a function, I need to add only one row to an existing table. However, when I run my code through the assignment checker, it keeps saying that I am making two rows. As a result, I keep failing the unit test.
The assignment also notes that I am not allowed to use insertCell and/or insertRow as it causes a problem with the auto-grader.
My approach to this problem is that if the sum of the array is equal to 0, get the existing table which has an id of distributionTable and append a single row to it. I used the browser inspect tool in order to debug to ensure that one row is present in the HTML.
Below is the function I created in JavaScript:

Answered 2019-Oct-05 at 18:00auto-grader seems to be confused.
Im willing to bet the grader is checking table.childNodes.length instead of table.children.length.
It should only be checking children and not childNodes.
Edit: And just to be done with the assignment (while they fix the grader) you could just do the following
QUESTION
I have an arraylist of arraylists which stores distances between points. I need to keep the original indexes of the distances after sorting the arraylist, because I need to find the K-nearest neighbours at a later stage of the code. The class I have implemented does not output the correct index of the distances instead an index of the arraylists only is the output
I have tried implementing a 2D comparable class but I was given a few errors.
...ANSWER
Answered 2019-Sep-03 at 03:08On review of your code, I think that the error is in your assumptions and that the output itself is in fact correct. The index that you're seeing is in fact the index of the outer Lists within your list of list nested array lists that you create here:
QUESTION
I have an arraylist which stores coordinate points as objects, I also have created a formula to calculate the distance between these respective points. I need to store each point with their respective distances in a 2D arraylist. For example if I have points (1,2),(3,4),(5,6),(7,8) my 2D arraylist should store 3 distances for point (1,2), two distances for point (3,4) and one distance for point (7,8) if point (1,2) is my start point.
I have tried creating a nested for loop which keeps track of where my point is currently while simultaneously adding the distances in each index based on the sample point visited. However I get an Out of Bounds exception. I have verified that all points are stored correctly.
...ANSWER
Answered 2019-Aug-16 at 09:26Let's say the list points has n elements. Then your for-loop here
for (int i = 0; i <= points.size(); i++) will end when i=n. But you can't access points at index n because it doesn't exist. Therefore points.get(i) will throw an IndexOutOfBoundsException once i==n (or i==points.size()).
Have a look at your indices one step at a time. Say your list points contains 3 elements:
QUESTION
I'm trying to generate a zobrist key for transposition tables in my chess engine. Here's how I'm generating the 64 bit numbers, as show here: How to generate 64 bit random numbers?
...ANSWER
Answered 2017-Jul-07 at 06:01Okay I did this to check out the distribution of random numbers; you can run this short program to generate a text file to look to see what values you are getting. Instead of using a function call I just used a lambda within the for loop and instead of setting the values into the array I wrote the values out to the text file before and after the post increment.
QUESTION
I have a problem using the hierarchy package in SciPy. Here there is an example of what my distance matrix is:
...ANSWER
Answered 2017-Dec-07 at 17:08You misunderstood the meaning of 'complete' method. It only means that the distance between two clusters of points, say {A, B} and {C, D}, is taken to be the maximum of pairwise distances AC, AD, BC, BD. This does not change the fact that hierarchical clustering combines nearby clusters, those with smallest distance from each other. There is no clustering method for "combine points if they are very far apart".
If you want large entries in your distance matrix (call it D) to mean "these are similar" then you have to transform D to invert the order relation between distances. In other words, the matrix you have measures similarity of objects and you need a measure of dissimilarity.
The simplest thing to do is to change the sign; linkage does not actually require distances to be positive.

Install distarray
You can use distarray 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.
