I know that it's possible to get string value from ref by doing
name = ref ""
name := "Dmitriy"
print("#{name}")
But i want to get float value from ref
freq = ref 0.0
def change_pitch()
freq := random.float(min=50.0,max=1000.0)
1.0
end
add_timeout(fast=true,1.0,change_pitch)
output.icecast(%mp3,
host = "coolgoga.hldns.ru", port = 8000,
password = "xxx", mount = "entity",
name="Entity Radio", genre="Any", description="EntityinArray's favourite
music",
sine(duration=0.1,!!!TOFLOAT_SOMEHOW(freq))
)
I want to make a sine wave tone that will change its pitch every second.
Thanks for help.
To extract value from reference you should prefix its name with '!'
def change_pitch()
freq := random.float(min=50.0,max=1000.0)
!freq
end
But i am not sure you even need a reference in your script
It will even work like this:
def change_pitch()
random.float(min=50.0,max=1000.0)
end

Cant figure out what the problem is
while wait(.5) do
local children = game.Players:GetChildren("Humanoid")
for i = 1, #children do
local hum = children[i] .Character.Humanoid
hum.HeadScale.Value = children[i].leaderstats.Points.Value/50 +1
hum.BodyHeightScale.Value = children[i].leaderstats.Points.Value/50 +1
hum.BodyWidthScale.Value = children[i].leaderstats.Points.Value/50 +1
hum.BodyDepthScale.Value = children[i].leaderstats.Points.Value/50 +1
hum.WalkSpeed = children[i].leaderstats.Points.Value/3.12
hum.JumpPower = children[i].leaderstats.Points.Value
hum.MaxHealth = children[i].leaderstats.Points.Value+25
end
end
was trying to get a simple size script to work.
The attempt to index nil with Humanoid error is telling you that the object that you are trying to grab the Humanoid out of doesn't exist. This line specifically :
local hum = children[i].Character.Humanoid
When a player joins the game, there is an indeterminate amount of time before their character model actually spawns into the world. So between when they join and when their character spawns, the Player.Character property is nil.
Your code does not handle the possibility that the character model is nil, and you are trying to access the humanoid immediately.
A safer approach is not to use a loop, but to observe changes to the leaderstats values and react to those changes. So in your code that creates your leaderstats objects, do something like this :
local Players = game:GetService("Players")
local function updateCharacter(hum : Humanoid, points : number)
local bodyScale = (points / 50) + 1
local walkSpeed = points / 3.12
local jump = points
local health = points + 25
hum.HeadScale.Value = bodyScale
hum.BodyHeightScale.Value = bodyScale
hum.BodyWidthScale.Value = bodyScale
hum.BodyDepthScale.Value = bodyScale
hum.WalkSpeed = walkSpeed
hum.JumpPower = jump
hum.MaxHealth = health
end
Players.PlayerAdded:Connect(function(player)
-- when a player joins the game, give them a leaderstats folder
local leaderstatsFolder = Instance.new("Folder")
leaderstatsFolder.Name = "leaderstats"
local pointsValue = Instance.new("IntValue", leaderstats)
pointsValue.Name = "Points"
pointsValue.Value = 0 -- or load from dataStores
leaderstatsFolder.Parent = player
-- listen for changes to the points and resize the character
pointsValue.Changed:Connect(function(newValue)
-- escape if the character doesn't exist
local character = player.Character
if character then
updateCharacter(character.Humanoid, newValue)
end
end)
-- when the character model spawns into the world, update it immediately with the player's point size
player.CharacterAdded:Connect(function(character)
updateCharacter(character.Humanoid, pointsValue.Value)
end)
end)
I have a multi-fuction script that is supposed to ask the user for 4 different cars and weigh them based on ratings to give the user the best car to purchase.
What I want to do is have a prompt for every car the user inputs so the user can put in data for each variable the user decides to use. However, when titling the prompt I want to use the cars name in the prompt. It seems impossible to me and Im not sure what to do, im very new to coding.
Main Script
prompt1 = {'How Many Cars (4): '};
title1 = 'Cars';
answer1 = inputdlg(prompt1, title1, [1 40]);
Q1 = str2double(answer1{1});
[N] = Group_Function1(Q1);
Car1 = N(1); %Stores the names of the cars
Car2 = N(2);
Car3 = N(3);
Car4 = N(4);
prompt2 = {'How Many Variables (4): '};
title2 = 'Variables';
answer2 = inputdlg(prompt2, title2, [1 50]);
fprintf('This code can accept costs between 0-100000\n');
fprintf('This code can accept top speeds between 0-200\n');
fprintf('This code can also accept the terms none, some, & alot\n');
fprintf('This code can accept safety ratings between 0-5\n');
Q2 = str2double(answer2{1});
[V,W] = Group_Function2(Q2);
W1 = W(1); %Stores the weights of the varibles
W2 = W(2);
W3 = W(3);
W4 = W(4);
for h=1:Q1
[H] = Group_Function3(V);
Weights(h,:)=H;
end
Group_Function1
function [N] = Group_Function1(Q1)
for Q = 1:Q1
prompt = {'Name of Car:'};
title = 'Car Name';
answer = inputdlg(prompt,title, [1 80])';
N(Q) = answer(1);
end
Group_Function2
function [V,W] = Group_Function2(Q2)
for Q=1:Q2
prompt = {'Variable? (Negative Variables First):','weights in decimal
form?'};
title = 'Variables and Weights';
answer = inputdlg(prompt,title, [1 80])';
V(Q)=answer(1);
W(Q)=str2double(answer{2});
s=sum(W);
end
if s~=1
fprintf('Weights do not add up to 1. Try Again!\n');
Group_Function2(Q2);
end
end
Group_Function3 (Where the problem occurs)
function [H] = Group_Function3(V)
prompt = {V};
title = ['Variable Ratings For' Group_Function1(answer{1})];
h = inputdlg(prompt, title, [1 80])';
end
The Problem
For 'Group_Function3' I want the prompt to include the users inputs from 'Group_Function1' so that when the prompt comes up to input the answers I know which vehicle I am entering for.
Each function runs in its own workspace, it means it does not know the state or content of variables outside of it. If you want a function to know something specific (like the name of a car), you have to give that to the function in the input parameters. A function can have several inputs parameters, you are not limited to only one.
Before going into the Group_Function3 , I'd like to propose a new way for Group_Function1.
Group_Function1 :
You run a loop to ask independantly for each car name. It is rather tedious to have to validate each dialog boxe. Here is a way to ask for the 4 car names in one go:
replace the beginning of your script with:
title1 = 'Cars';
prompt1 = {'How Many Cars (4): '};
answer1 = inputdlg(prompt1, title1 );
nCars = str2double( answer1{1} );
CarNames = getCarNames(nCars) ; % <= use this function
% [N] = Group_Function1(Q1); % instead of this one
and replace Group_Function1 with:
function CarNames = getCarNames(nCars)
title = 'Car Names';
prompt = cellstr( [repmat('Name of car #',nCars,1) , sprintf('%d',(1:nCars)).'] ) ;
CarNames = inputdlg( prompt, title, [1 80] ) ;
end
Now CarNames is a cell array containing the name of your 4 cars (as your variable N was doing earlier. I recommend sligthly more explicit variable names).
You can run the rest of your code as is (just replace N with CarNames, and Q1 with nCars).
Group_Function3 :
when you get to the Group_Function3, you have to send the current car name to the function (so it can use the name in the title or prompt). So replace your Group_Function3 as following (we add an input variable to the function definition):
function H = Group_Function3( V , thisCarName )
prompt = {V};
title = ['Variable Ratings For' thisCarName];
H = inputdlg(prompt, title, [1 80])';
end
and in your main script, call it that way:
for h = 1:nCars
thisCarName = carNames{h} ;
H = Group_Function3( V , thisCarName ) ;
% ...
% anything else you want to do in this loop
end
I am trying to convert some data with the indicated measurements package, but I'm not succeeding on it.

What I'm trying:
library(measurements)
library(readxl)
coord = read.table('coord_converter.txt', header = T, stringsAsFactors = F)
# change the degree symbol to a space
lat = gsub('°','', coord$Lat)
long = gsub('°','', coord$Long)
# convert from decimal minutes to decimal degrees
lat = measurements::conv_unit(lat, from = 'deg_dec_min', to = 'dec_deg')
long = measurements::conv_unit(long, from = 'deg_dec_min', to = 'dec_deg')
What I'm getting with this penultimate line:
Warning messages:
In split(as.numeric(unlist(strsplit(x, " "))) * c(3600, 60), f = rep(1:length(x), : NAs introduced by coercion
In as.numeric(unlist(strsplit(x, " "))) * c(3600, 60) : longer object length is not a multiple of shorter object length
In split.default(as.numeric(unlist(strsplit(x, " "))) * c(3600, : data length is not a multiple of split variable
Can someone point my mistake or make a suggestion of how to proceed?
Thank you!
I think the issue here was that after gsub call, degrees and minutes were not space delimited, as required by measurements::conv_unit.
For example, this works fine (for this reproducible example I also changed "ᵒ" to "°"):
library(measurements)
#read your data

Lets say that I want to have unlimited path segements and have the get multiply them together such that:
get "/multiply/num1/num2/num3......" do
num1 = params[:num1].to_i
num2 = params[:num2].to_i
....
solution = num1 * num2 * ....
"the solution is = #{solution}"
end
I want the user to be able to type out as many path segments as they want and then get the solution for those numbers multiplied together.
I have found a way to do it:
get "/multiply/*" do
n = params[:splat][0].split('/')
for i in (0...n.length)
n[i] = n[i].to_f
end
n = n.inject{ |sum, n| sum * n }
"solution = #{n}"
end
I'm new to Matlab and now learning the basic grammar.
I've written the file GetBin.m:
function res = GetBin(num_bin, bin, val)
if val >= bin(num_bin - 1)
res = num_bin;
else
for i = (num_bin - 1) : 1
if val < bin(i)
res = i;
end
end
end
and I call it with:
num_bin = 5;
bin = [48.4,96.8,145.2,193.6]; % bin stands for the intermediate borders, so there are 5 bins
fea_val = GetBin(num_bin,bin,fea(1,1)) % fea is a pre-defined 280x4096 matrix
It returns error:
Error in GetBin (line 2)
if val >= bin(num_bin - 1)
Output argument "res" (and maybe others) not assigned during call to
"/Users/mac/Documents/MATLAB/GetBin.m>GetBin".
Could anybody tell me what's wrong here? Thanks.
You need to ensure that every possible path through your code assigns a value to res.
In your case, it looks like that's not the case, because you have a loop:
for i = (num_bins-1) : 1
...
end
That loop will never iterate (so it will never assign a value to res). You need to explicitly specify that it's a decrementing loop:
for i = (num_bins-1) : -1 : 1
...
end
For more info, see the documentation on the colon operator.
for i = (num_bin - 1) : -1 : 1
