Hi Emma you can still use the approach. It also works for multiple coordinates given. Please see my example below, which does it for 3 coordinates. (1 coordinate pair extra) You can add as many additional "waypoints" as you like:

How to repeat the last few frames of animation for React Animation

Asked 2020-Jun-15 at 14:12

I have an app which the user holds down the screen and an animation starts to play. This is not a normal animation. It uses multiple frames to create this animation much like a cartoon from Disney :) The animation plays from the start to the end and loops. But I want it to loop over the last 4 or 5 frames repeatedly. At the moment it doesn't do this.

QUESTION

Data structure for a diamond-shaped array in python

Asked 2020-Apr-13 at 13:03

I have two arrays that are related to each other via a mapping operation. I will call them S(f_k,f_q) and Z(f_i,α_j). The arguments are all sampling frequencies. The mapping rule is fairly straightforward:

f_i = 0.5 · (f_k - f_q)
α_j = f_k + f_q

S is the result of several FFTs and complex multiplications and is defined on a rectangular grid. However, Z is defined on a diamond-shaped grid and it is not clear to me how best to store this. The image below is an attempt at visualizing the operation for a simple example of a 4×4 array, but in general the dimensions are not equal and are much larger (maybe 64×16384, but this is user-selectable). Blue points are the resulting values of f_i and α_j and the text describes how these are related to f_k, f_q, and the discrete indices. The diamond-shaped nature of Z means that in one "row" there will be "columns" that fall in between the "columns" of adjacent "rows". Another way to think of this is that f_i can take on fractional index values!

Note that using zero's or nan's to fill in elements that don't exist in any given row has two drawbacks 1) it inflates the size of what may already be a very large 2-D array and 2) it does not really represent the true nature of Z (e.g. the array size will not really be correct).

Currently I am using a dictionary indexed on the actual values of α_j to store the results:

You can still view it as a straight two-dimensional array. But you can represent it as an array of rows, each row of which has a different number of items. For example, here's your 4x4 as a 2D array: (each 0 here is a unique data item)

QUESTION

Equivalent of FlatList from React Native in React

Asked 2019-Aug-07 at 13:10

Is there an equivalent of the FlatList component from React Native in React? Having built a mobile app in React Native, I'm now converting it to React for a web app. (Have considered using react-native-web, but have decided against it, mainly because I want to learn React.)

If there isn't an equivalent, I have been thinking about just using map() to render all the items via an Item component that I build, also as demonstrated here in the docs and in this SO question.

Answered 2018-Sep-28 at 08:40

This project includes a lot of the features for Flat List/List View - but seems to approve upon it, it's for React Native and Web, you can read this article:

https://medium.com/@naqvitalha/recyclerlistview-high-performance-listview-for-react-native-and-web-e368d6f0d7ef

Some interesting points:

FlatList:

FlatList is amazing and comes with tons of features. It even lets you render separators and comes with a built in customisable view tracker which is something we were interested in.

FlatList is a virtualized listview and it does so by unmounting views that have gone out of viewport. It does help bring down overall memory usage down but there are cons to this approach:

Views on native end get destroyed causing lot of garbage collection. Views need to be recreated now as you scroll up which might be a problem if the scroll is quick.

QUESTION

Unexpected Behavior when Removing Items in React.js

Asked 2019-May-19 at 00:39

I've started to brush up on React after a long time away. Pretty much I have a "list" that stores companies interview processes. This is built by 2 react components. Is the list that aggregates each job.

When you go to "remove row" react registers the correct "row" to delete, (and by using a debugging simple case this happens) but it will not successfully update the inner component.

I've spent time researching this, and I've added a simple component called "Welcome." This helps me because I can use this to validate that I am removing the correct element, just the inner "jobrow" component is not updating correctly.
