Collision Detection – The signal entered by the body will not be emitted when a rigid body will collide with a rigid body

By default, a RigidBody does not emit a signal when it collides with another RigidBody. This is usually a good thing because RigidBodies can collide frequently and emit many signals that are not of interest to you, which would have a negative impact on performance.

If you make care about detecting RigidBody the collisions you should define RigidBody.contact_monitor at true and RigidBody.contacts_reported at a value greater than 0.

From the docs on contact_monitor:

If true, the RigidBody will emit signals when it collides with another RigidBody.

java – Arraylist overwriting previously entered values

Hi, I'm trying to create multiple client records and assign them to an arraylist so I can search for them later, but when I call the register creation method and assign them to an arraylist, I will create another register. and I ask to display the arraylist it displays the two entries created previously with the same values, thanks if you can help me!

Encryption – How can I validate that a PGP public key entered by the user is valid?

we want to encrypt the emails we send to the user with his public key.
it works fine, but the user can also type a broken / invalid public key ("asdf123") and the encryption will obviously not work.

How can I validate the fact that the user has entered a public key pgp with a correct format?

average values ​​entered in python input

I make a program that takes a value entered input (other than negative and less than 20) and calculates:
a) the highest value;
(b) the smallest value;
(c) the sum of the values;
(d) the arithmetic mean of the values;
e) the number of even numbers;
f) The number of odd numbers.
I've already done the biggest, the smallest and the biggest, but I do not know how to get the average, even and odd

valor = input('Digite um número menor que 20 que seja positivo: ') #pede para um usuário digitar um número
if not valor.isdigit():
    print('Digite apenas números positivos!')
    maximo = max(valor)
    minimo = min(valor)
    soma = 0
    for valor in valor: #verifica elemento a elemento dentro de um for e faz a soma dessa lista
        soma += int(valor)
    print('O maior valor é:',maximo)
    print('O menor valor é:',minimo)
    print('A soma é:',soma)
    print('A média é:',media)

and i also want to know how i do not type a number greater than 20, and if he types, returns an error and asks him to type again

Performance – Find a perfect square smaller than a number entered (Swift)

This code is slow even with numbers less than 1,000,000. Can someone help me optimize this thing?

// Finds the highest perfect square below a certain input (int)

let target: Int = 758865 // Swap this out for testing other numbers
var smlSqr = (Int)()
let findLimit = Int(Double(target).squareRoot().rounded(.up))   // Saves CPU time, because perfect squares less than
                                                                // number a but higher than a.squareRoot is impossible.

var index = 0
var maxSqr = 0 // Final result
var candidate = 0

repeat {
    smlSqr.append(index * index)
    index += 1
} while(index < findLimit)

while candidate < smlSqr.count {
    if smlSqr(candidate) > maxSqr {
        maxSqr = smlSqr(candidate)
    candidate += 1

print(String(maxSqr)) // For debugging, should print out 100
print(Int(Double(maxSqr).squareRoot())) // For debugging, making sure the number is actually a perfect square

I'm using Swift 5.1 on Xcode 11.
Also using a playground (if that helps)

react – Problem transmitting a value entered in TextField in SPFx and adding it to a SharePoint list

I'm doing a little project there, I want to add tulips to a SharePoint list using SharePoint Framework with React.

I use Textfield and so UI Fabrics and PnPJs to get data from lists and so on. It works well to add hard-coded states when you click the "ADD" button does not work when you try to enter a value from the text field.

Here's what the application looks like now:
enter the description of the image here

Here is the code:


import * as React from 'react';
import styles from './EnfokamTulips.module.scss';
import { IEnfokamTulipsProps } from './IEnfokamTulipsProps';

import AddTulips from './AddTulips'

export default class EnfokamTulips extends React.Component {
  public render(): React.ReactElement {
    return (
); } }


import * as React from 'react';
import { TextField } from 'office-ui-fabric-react/lib/TextField';
import { DefaultButton } from 'office-ui-fabric-react';
import { sp, ItemAddResult } from '@pnp/sp';

export interface IEnfokamTulipsState {
    title: string;
    manufacturingCost: number;

this.state = {
    title: 'book',
    manufacturingCost: 2

function addTulipsToList(event) {

    // get all the items from a list
    sp.web.lists.getByTitle("Tulips")"Title").get().then((items: any()) => {

// add an item to the list
        Manufacturing_x0020_cost: //Internal name of column
        }).then((iar: ItemAddResult) => {

let addTulips = (event) => {
) } export default addTulips;


export interface IEnfokamTulipsProps {
  description: string;

export interface IEnfokamTulipsState {
  title: string;
  manufacturingCost: number;

export interface TulipsLists{
  value: TulipsList();
export interface TulipsList{
  Title: string;
  Manufacturing_x0020_cost: number; 

The only thing that happens when I click on the "Add" button is this:
enter the description of the image here

All data in each column is empty.
What am I doing wrong?
What I want is that no matter what I type in the text fields, I want to pass it and show it in the list when I click on "ADD".

Any help is appreciated.
