I am trying to 'avoid walls' using an A* star (A-Star) algorithm. My array look like this:...
ANSWERAnswered 2022-Apr-04 at 06:20
Here's an example where it just finds all the values that are zero in each row and sets the path as the middle argument. If there was a row with two patches of zeros, this could run into trouble. In that case, you would need to make sure that the arguments above and below a zero patch are also zero patches.
I have used matplotlib here to visualize the path:
I'm trying to adapt Sebastian Lague's A-Star path finding code (youtube) to 3 dimensions. I have it somewhat working but occasionally the path produced between my nodes is sub-optimal, and I think it's because I'm calculating distance wrong.
To move along a single dimension from one node to the next is a distance of 1. To move in 2 dimensions (diagonally) the distance is √2 (which is simplified to 1.4 in the code). These values are multiplied by 10 to keep them as integers, so 10 and 14 respectively.
To calculate the distance on a 2d plane you take the smaller of the X and Y distances and multiply it by 14, then minus the smaller distance from the larger one and multiply what remains by 10....

In your code, changing location in two dimensions should be based on 14 (10 * square root of 2), but changing in all three dimensions at once should be based on 17 (10 * square root of 3), if my quick math is correct. I suspect that may solve your issue.
(Sure enough...here's a short explanation of why it should be based on sqrt(3).)

I have an Index.js where I am getting data via async function and sending data to ProductList Component and from ProductList Component I am sending an id onclick of product Image and then I get Product Detail Page a Single Product. I get Single Product with no issues but when I refresh then I get an error in console saying - Cannot read properties of undefined (reading 'filter') I have used REDUX.
ANSWERAnswered 2022-Feb-23 at 16:58
From what I can see, the
ProductDetails component is missing a dependency on the
id route param to select the correct products to filter, and I am assuming that since the index file is fetching and populating the store each time it mounts that perhaps the initial products state is null, undefined, or some other non-array value that is missing the
Add the missing
id route param to the
useEffect hook's dependency array so products are fetched when the route changes.

you can use jquery library:
I have implemented a search bar on my website and when a name of a product card is typed in it works. However, if you was to type in a word such as "lol' or any other word that is not included on the product cards the footer begins to show. I'm wanting the footer to stay in its current place which is at the bottom of the page.
I will be uploading code snippets and the files to my server so you can view the entire website and the problems I am experiencing.
I hope all of the information provided shows the problem I am experiencing.

I would just wrap it with id or class and set it
min-height:100vh;. Its the easiest way, not the cleanest code. Hope it helped!
I am sending an
ProductListing Component and I am receiving that
ProductDetail Component. In
ProductDetail Component I am finding an object using find method and then I am setting it into
singleProduct state. On refresh I get
singleProduct is undefined.
ANSWERAnswered 2022-Jan-24 at 11:02
That's a normal behaviour, state is being reset on refresh per specification. If you want to preserve it you need to make use of localStorage/sessionStorage/cookies etc.
Which is best way?
Well I would say that the second approach is better. I would avoid keeping copy of state in localstorage. I would only keep some kind of token/id (in your case uid) which uniquely identify the user and would fetch fresh data every time. When your application grows it can be hard to manage those states in localstorage.

You can use A-star like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the A-star component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
