This program is supposed to calculate the varying stopping power as a proton travels through aluminium for 20000 slices of 0.025µm of aluminium. The stopping power changes per slice, so the stopping power and subtraction of energy has to be calculated per slice. I get a stack overflow error even after attempting to increase the… Read More How to fix Recursion Function overflow error?
Im programming a magnetic field simulator with a max of 4 charges but i dont understand what is wrong with the angle calculation. function generarCargas is the function that creates the arrows, sorry if i didnt comment, if you have any questions with the code i will answer immediately. JS: //Funcion angle function angle(cx, cy,… Read More Problems to calculate the angle of the arrows to simulate a magnetic field
Have a task and need to figure out the start velocity of an iron ball shot vertically upwards. We know this information. >Solution : The values from your image are as follows: mass sphere: 263.8602726 kg drag coefficient: 0.47 air density: 1.225 kg/m³ max height: 80 m acceleration due to gravity (G): 9.805 m/s² Assuming… Read More create python code to figure out start velocity
for some reason when a ball hits the left wall it gains momentum i tried using "* -1" instead of "-" heres the code y = y + vel_y x = x + vel_x vel_y = vel_y + 1 if y >= 900: y = 900 vel_y = -(vel_y – 10) if x >= 900:… Read More weird physics bug when a ball hits the left wall
I am wanting to plot many datasets on one plot in python. Currently, I have hardcoded 20 of the datasets for the sake of testing my plot. Here is the shortened code below: import numpy as np import matplotlib as plt N_steps = 1000 N_plot = 20 xorb_list = np.empty((N_plot, N_steps)) yorb_list = np.empty((N_plot, N_steps))… Read More How can I add many datasets to a single plot in python?
I was making a Physics Engine in C++ when I noticed that when I replace: float absDistance = sqrt(vectorDistance.x * vectorDistance.x + vectorDistance.y * vectorDistance.y); With: float absDistance = abs(vectorDistance.x) + abs(vectorDistance.y) Different things happen. I’m using the library <cmath> I looked at a lot of stack exchanges but I couldn’t find anyone saying they’re… Read More Why is abs(x)+abs(y) different from sqrt(x*x + y*y)
I have a game which spawns several objects but with the name (Clone) next to it, however I want to remove (Clone). Excuse me, I am new to Unity, and have tried several solutions but never worked. I can send script file of instantiating objects if needed. public void InstantiateObject() { if(Input.GetMouseButtonDown(1)) { Ray ray… Read More Remove (Clone) name from gameobject spawned
my code is here ( https://www.codepile.net/pile/7mPpA9m0 ) the player is go out of box of canvans how to make it restrict >Solution : Just call the method setCollideWorldBounds on the players physics object, than the player should not be able to leave, teh Zone. In the create function just add this line of code: this.player.body.setCollideWorldBounds(true);
The below code does not display any data when the bottomsheet loads. Once the bottomsheet is loaded if I do a save operation on the code editor it loads the data. What am I missing here? I have a bottomsheet widget which is invoked using a button. _showBottomSheet() { showModalBottomSheet( context: context, builder: (context) {… Read More Flutter Listview.Builder inside bottom sheet widget not loading data on load
For example, a camera that generates Raycast and if it hits it destorys an object. public class RaycastScript : MonoBehaviour { void CheckForRaycastHit() { RaycastHit hit; //if raycast hit if(Physics.Raycast(transform.position, transform.forward, out hit)) { print(hit.collider.gameObject.name + " hit"); //print what object got hit Destroy(hit.collider.gameObject); //destroy object } } void Update() { //mouse controls camera float… Read More How to get access to "mesh renderer" of a different object using raycast?
