I'm new to AnyLogic and I am trying to create a custom network...but i don't get to succeed in this task :(
Agents have a parameter "AgeClass", that is an int from 0 to 14, according to their age.
Then I have a variable "network" that contains the mean number of links between age class.
What I want is every agent to create link with other agent according to the matrix.
I don't get how I can say to an agent "connect to another agent with AgeClass = 3"
I thought something like this (to put in the "on startup block" or in an event inside the agent type):
int i = AgeClass \\ this is the AgeClass of the agent who is executing the code
for( int j=0; j<network[i].length; j++ ) { \\ in this way I go through all the age classes
for ( int k=0; k<poisson(network[i] [j]); k++) { \\ for every j I get the mean # of link
connectTo(????);
}
}
Instead of ???? i want to say "connect to another agent with AgeClass = j" ...is there a way thorugh?
Thanks for the support!!!
Please use the function "filter()" to select all agents from the population with AgeClass = j. Then, you can get random of them to connect to the agent executing the code. The expression ???? may look like:
randomFrom(filter(main.people, p -> p.AgeClass == j))
Here is the description of the function "filter()":

Code:
local DataStoreService = game:GetService("DataStoreService")
local InvDataStore = DataStoreService:GetDataStore("InvDataStore")
game.Players.PlayerAdded:Connect(function(player)
local Id = player.UserId
local Inventory = Instance.new("Folder")
Inventory.Name = "Inventory"
Inventory.Parent = player
local Inv = InvDataStore:GetAsync(Id)
print(Inv)
print(table.concat(Inv, " "))
end)
game.Players.PlayerRemoving:Connect(function(player)
local Id = player.UserId

for i, v in pairs(game.Players:FindFirstChild(player.Name).Inventory:GetChildren()) do
print("Repear")
if v:IsA("NumberValue") then
table.insert(InvTable, v)
print(v)
end
end
print(InvTable)
print(table.concat(InvTable, " "))
InvDataStore:SetAsync(Id, InvTable)
end)
Output:

It seems to be skipping this loop:
for i, v in pairs(game.Players:FindFirstChild(player.Name).Inventory:GetChildren()) do
print("Repear")
if v:IsA("NumberValue") then
table.insert(InvTable, v)
print(v)
end
end
as it seems to not print repear (repeat) OR v (Value) anyone know whats up?
Note: The thing i dont understand, is it doesnt print the value after the save, and before the save, and forgetting the for loop. I can provide extra things to.
It is ignoring the loop because when it gets to game.Players:FindFirstChild(player.Name) the return will be nil, due to that player just leaved the server. What you can try to do is iterating directly from the player object you have, you don't need to look for the object player if you already have it.
Try:
for i, v in pairs(player.Inventory:GetChildren()) do
print("Repear")
if v:IsA("NumberValue") then
table.insert(InvTable, v)
print(v)
end
end
also it is a good practice to store data during the game and not when it leaves, all those objects are removed too when the player leaves, it is better to handle the table during the game and during player removing just update the data store.
Also a good practice is to update datastore for the player every ~5 minutes
So, I've been working on this for the past week. I have tried everything (based on the knowledge I know) and yet nothing... my code didn't work the first time, the second time, the third time... the forth... etc... at the end, I let frustration take control of me and I ended up deleting the whole script. Luckily not the parts and models, otherwise I'm really screwed...
I need to create a game in which I have to create a keypad of sorts, at first I thought GUI would work... no, it needs to be SurfaceGUI, which I don't know how to handle well... Anyway, I needed to create a keypad using SurfaceGUI, and display it on a separate screen, as a typical keypad would...
The Player would first have to enter an "initial" number, meaning in order to enter the randomly generated number he first needed to input the static pin in order to "log in," after that, then he would try to guess the number...
I've literally tried everything I could but nothing... It's mainly because of my lack of experience in LUA, I'm more advanced in Python and barely know a thing in Java... If someone could assist me on how to do this, I would appreciate it greatly
First, download this and put it in a ScreenGui in StarterGui. Then, use the following LocalScript placed inside the PIN frame:
-- Script settings
local len = 4 -- replace this as needed...
local regen = false -- determines whether PIN will regenerate after a failed attempt
local regmes = "Enter PIN..." -- start message of PIN pad
local badmes = "Wrong PIN!" -- message displayed when PIN is wrong
local success = "Correct PIN!" -- message displayed when PIN is right
-- Script workings
local pin = script.Parent
local top = pin.Top
local txt = top.Numbers
local nums = top.NumKeys
local pin
local stpin
local nms
txt.Text = regmes
local see = game:GetStorage("ReplicatedStorage").PINActivate
local function activate()
if pin.Visible then
pin.Visible = false
for _, btn in pairs(nums:GetChildren()) do
btn.Active = false
end
return
else
pin.Visible = true
for _, btn in pairs(nums:GetChildren()) do
btn.Active = true
end
return
end
end
local function rand()
math.randomseed(os.time) -- better random numbers this way
return tostring(math.floor(math.random(0,9.9)))
end
local function gen()
nms = {rand()}
for i=2, len, 1 do
nms[#nms+1]=rand()
end
stpin = nms[1]
for i=2, #nms, 1 do
stpin = stpin..nms[i]
end
pin = tonumber(stpin) -- converts the number string into an actual number
end
gen()
local function activate(str)
if tonumber(str) ~= pin then
txt.Text = badmes
wait(2)
txt.Text = regmes
if regen then
gen()
wait(0.1)
end
return
else
txt.Text = success
wait(2)
activate()
-- insert code here...
end
end
for _, btn in pairs(nums:GetChildren()) do
btn.Activated:Connect(function()
if txt.Text == "Wrong PIN!" then return end
txt.Text = txt.Text..btn.Text
if string.len(txt.Text) >= len then
activate(txt.Text)
end
wait(0.1)
end)
end
see.OnClientEvent:Connect(activate)
And in a Script put this:
local Players = game:GetService("Players")
local see = game:GetService("ReplicatedStorage").PINActivate
local plr
-- replace Event with something like Part.Touched
Event:Connect(function(part)
if part.Parent.Head then
plr = Players:GetPlayerFromCharacter(part.Parent)
see:FireClient(plr)
end
end)
What this will do is bring up a ScreenGui for only that player so they can enter the PIN, and they can close it as well. You can modify as needed; have a great day! :D
There is an easier way, try this
First, Create a GUI in StarterGui, then, Create a textbox and postion it, after that, create a local script inside and type this.
local Password = math.random(1000, 9999)
print(Password)
game.ReplicatedStorage.Password.Value = Password
script.Parent.FocusLost:Connect(function(enter)
if enter then
if script.Parent.Text == tostring(Password) then
print("Correct!")
script.Parent.BorderColor3 = Color3.new(0, 255, 0)
Password = math.random(1000, 9999)
game.ReplicatedStorage.Correct1:FireServer()
print(Password)
game.ReplicatedStorage.Password.Value = Password
else
print("wrong!")
print(script.Parent.Text)
script.Parent.BorderColor3 = Color3.new(255, 0, 0)
end
end
end)
That's all in the textbox.
Or if you want a random username script, create a textlabel, then, create a local script in the textlabel and type in this.
local UserText = script.Parent
local Username = math.random(1,10)
while true do
if Username == 1 then
UserText.Text = "John"
elseif Username == 2 then
UserText.Text = "Thomas"
elseif Username == 3 then
UserText.Text = "Raymond"
elseif Username == 4 then
UserText.Text = "Ray"
elseif Username == 5 then
UserText.Text = "Tom"
elseif Username == 6 then
UserText.Text = "Kai"
elseif Username == 7 then
UserText.Text = "Lloyd"
elseif Username == 8 then
UserText.Text = "Jay"
elseif Username == 9 then
UserText.Text = "User"
else
UserText.Text = "Guest"
end
wait()
end
All of those if statments are checking what username has been chosen. I have made a roblox game like this recently, so I just took all the script from the game.

I have this links.csv file:
METHOD,HOST,PATH,HITS
GET,google.com,/,7
GET,facebook.com,/,3
I want to create a JMeter test plan using Ultimate Thread Group (UTG) that randomize the hits based on the last column in the CSV above (HITS).
When viewing the results tree, I want to see something like this:
1. google.com
2. google.com
3. facebook.com
4. google.com
5. google.com
6. google.com
7. google.com
8. google.com
9. facebook.com
10. facebook.com
Ideally, I want to set the UTG to use the following settings:
Start Threads Count = sum of all hits in the CSV file (e.g. 7 + 3)
Initial Delay = 0
Startup Time = 60
Hold Load For = 30
Shutdown Time = 0
How to achieve this? I appreciate code samples and screenshots since I'm still new to JMeter.
I can only think of generating a new CSV file out of your original one in order to:
Get the "sum" of "HITS"
Generate a line containing method, host and path per "hit"
In order to achieve this:
Add setUp Thread Group to your Test Plan
Add JSR223 Sampler to the Thread Group
Put the following code into "Script" area:
def entries = new File('/path/to/original.csv').readLines().drop(1)
def sum = 0
def newCSV = new File('/path/to/generated.csv')
newCSV << 'METHOD,HOST,PATH' << System.getProperty('line.separator')
entries.each { entry ->
def values = entry.split(',')
def hits = values[3] as int
sum += hits
1.upto(hits, {
newCSV << values[0] << ',' << values[1] << ',' << values[2] << System.getProperty('line.separator')
})
}
props.put('threads', sum as String)
Use __P() function like ${__P(threads,)} in the Ultimate Thread Group
Use the new "generated" CSV file in the CSV Data Set Config in the Ultimate Thread Group
I am trying to get vehicle id as follow:
mobility = TraCIMobilityAccess().get(getParentModule());
assert(mobility);
traci = mobility->getCommandInterface();
traciVehicle = mobility->getVehicleCommandInterface();
cout<< mobility->getExternalId();
But it returns an invalid vehicle id. What is wrong?
Please help me to solve this problem. Thanks.
What do you mean by an invalid vehicle id? The way you are getting the identifier is the one used by sumo. If that is the case, can you specify what do you expect as an identifier? (that of omnet which starts from [1]?)
As the id of SUMO and that one apparent in omnet are not the same (the order of creation), you may add the following to get your own id (that matches the one of omnet) :
in the ".h" file of your TraCIDemo11p, add your id:
protected:
int your_id;//added
in the ".c" file of your TraCIDemo11p, affect the index in your id:
if (stage == 0) {
...
your_id = getParentModule()->getIndex();//added
...
next, in the place you want to verify a statement, add this:
EV << "My SUMO id = " << mobility->getExternalId() << endl;
EV << "My VEINS id = " << your_id /*or just : getParentModule()->getIndex()*/<< endl;
I hope this helps.
You can try the FindModlue::findHost() in DemoBaseApplLayer::initialize(int stage) in DemoBaseApplLayer.cc:
EV << FindModule<BaseMobility*>::findHost(getParentModule())->getId() << endl;
It will first return the host module and then use the getId() function to get its id.
For better understanding:
Firstly, you can run the simulation to see the indexing of the whole simulation and it would be like this:
Simulation information in veins
As read from the figure, each objects are assigned to a number, e.g. node[0]has the id 7, besides that, each sub-modules are also assigned with id numbers, e.g.
node[0] id = 7
appl id = 8
nic id = 9
veinsmobility id = 10
All of this ids (7,8,9,10) point to the node[0], which means you can use thoese ids to identify a specific car.
In the default DemoBaseApplLayer.cc, you can find
mac = FindModule<DemoBaseApplLayerToMac1609_4Interface*>::findSubModule(getParentModule());
and
myId = mac->getMACAddress();
in the initialization function void DemoBaseApplLayer::initialize(int stage).
Therefore, you can already use the myId as the vehicle id.
By the way, the reason that you get the 18 and 20 for vehicle id, is that the returned module might just be the host module and the sub-module, e.g. 18 is for the node[*] and the 20 is for its nic sub-module.
I'm studing Aparapi (https://code.google.com/p/aparapi/) and have a strange behaviour of one of the sample included.
The sample is the first, "add". Building and executing it, is ok. I also put the following code for testing if the GPU is really used
if(!kernel.getExecutionMode().equals(Kernel.EXECUTION_MODE.GPU)){
System.out.println("Kernel did not execute on the GPU!");
}
and it works fine.
But, if I try to change the size of the array from 512 to a number greater than 999 (for example 1000), I have the following output:
!!!!!!! clEnqueueNDRangeKernel() failed invalid work group size
after clEnqueueNDRangeKernel, globalSize[0] = 1000, localSize[0] = 128
Apr 18, 2013 1:31:01 PM com.amd.aparapi.KernelRunner executeOpenCL
WARNING: ### CL exec seems to have failed. Trying to revert to Java ###
JTP
Kernel did not execute on the GPU!
Here's my code:
final int size = 1000;
final float[] a = new float[size];
final float[] b = new float[size];
for (int i = 0; i < size; i++) {
a[i] = (float)(Math.random()*100);
b[i] = (float)(Math.random()*100);
}
final float[] sum = new float[size];
Kernel kernel = new Kernel(){
#Override public void run() {
int gid = getGlobalId();
sum[gid] = a[gid] + b[gid];
}
};
Range range = Range.create(size);
kernel.execute(range);
System.out.println(kernel.getExecutionMode());
if (!kernel.getExecutionMode().equals(Kernel.EXECUTION_MODE.GPU)){
System.out.println("Kernel did not execute on the GPU!");
}
kernel.dispose();
}
I tried specifying the size using
Range range = Range.create(size, 128);
as suggested in a Google group, but nothing changed.
I'm currently running on Mac OS X 10.8 with Java 1.6.0_43. Aparapi version is the latest (2012-01-23).
Am I missing something? Any ideas?
Thanks in advance
Aparapi inherits a 'Grid Style' of implementation from OpenCL. When you specify a range of execution (say 1024), OpenCL will break this 'range' into groups of equal size. Possibly 4 groups of 256, or 8 groups of 128.
The group size must be a factor of range (so assert(range%groupSize==0)).
By default Aparapi internally selects the group size.
But you are choosing to fully specify the range and group size to using
Range r= Range.range(n,128)
You are responsible for ensuring that n%128==0.
From the error, it looks like you chose Range.range(1000,128).
Sadly 1000 % 128 != 0 so this range will fail.
If you specifiy
Range r = Range.range(n)
Aparapi will choose a valid group size, by finding the highest common factor of n.
Try dropping the 128 as the the second arg.
