I have some troubles with a simple code that I've made :
SWEP.PrintName = "Gestionnaire d'alarmes Administrateur"
SWEP.Author = "Frass"
SWEP.Instructions = "Clic Gauche : Ouvrir le gestionnaire"
SWEP.Spawnable = true
SWEP.AdminOnly = true
SWEP.Primary.ClipSize = -1
SWEP.Primary.DefaultClip = -1
SWEP.Primary.Automatic = false
SWEP.Primary.Ammo = "none"
SWEP.Secondary.ClipSize = -1
SWEP.Secondary.DefaultClip = -1
SWEP.Secondary.Automatic = true
SWEP.Secondary.Ammo = "none"
SWEP.Weight = 5
SWEP.AutoSwitchTo = false
SWEP.AutoSwitchFrom = false
SWEP.Slot = 1
SWEP.SlotPos = 2
SWEP.DrawAmmo = false
SWEP.DrawCrosshair = true
SWEP.ViewModel = "models/weapons/v_pistol.mdl"
SWEP.WorldModel = "models/weapons/w_pistol.mdl"
local ShootSound = Sound( "buttons/button14.wav" )
function SWEP:PrimaryAttack()
self:TabletMenu()
end
function TabletMenu() (reduced, there's a lot of code inside)
When I try to use my SWEP in GMOD, the console give me this error :
[ERROR] lua/weapons/alarmtabletld.lua:44: attempt to call method 'TabletMenu' (a nil value)
1. unknown - lua/weapons/alarmtabletld.lua:44
I really don't understand what is doing this error...
Some help could be really nice !
You are calling a TabletMenu function that doesnt exist as part of the SWEP table. Is it defined somewhere else perhaps?

I'm making an action RPG in Love2d, and I moved all of my player code into a separate Lua script for the sake of organization - but now upon attempting to use player.load, I get this error:
Error
main.lua:22: attempt to index global 'player' (a boolean value)
Traceback
main.lua:22: in function 'load'

this is my main.lua script:

function love.load(dt)
player = require 'Scripts/player'
player.load()

gameMap = sti('Maps/overworld.lua')
menuImg = love.graphics.newImage('Assets/Menu.png')
love.window.setMode(800, 600)
end
function love.draw(dt)
if Room == 0 then

and this is my player.lua script:

end
Any help would be much appreciated!
Here's my folders as well, just in case it's a path issue:
UPDATE:
I solved it by renaming the player object to oPlayer, that was what was giving me an error.
I have severall Hints for you
Unclear
It looks you write it under Linux but should it also run under Windows?
If so, use OS independent folder delimiter ( the dot ) in require().
Example
player = require 'Scripts.player'
In General: Dont use Slash / Backslash \ in require()
Tip: LÖVE uses LuaJIT with modified Lua 5.1 check the Windows OS is easy
(For deciding to use Slash or Backslash (not in/for require()))
Clear
As #Luke100000 mentioned...
A Script for require has to return something.
If not than only a true wil be cached and a next require returns only true.
Therefore your player.lua content should be...
-- player.lua
local player = {x = 50, y = 50, speed = 3, state = 0, img = nil}
-- player.load() will be local
-- GetInput() wil be global
-- And the last line...
return(player)
I have a code that defines a function, then I try to use the variables I defined within that function in another expression. When I do this, I get an error that is:
Undefined function or variable 'phi'.
I'm not sure why phi is undefined, since I have it in the if/else statement.
It might be better to explain with my (shortened) code:
global I11 I22 I33 Mx My Mz w10 w20 w30 eps10 eps20 eps30 eps40...

opts = odeset('RelTol', 1*10^(-10),'AbsTol', 1*10^(-10));
[t, y] = ode45(#(t,y) DynEqn2(t,y,I11,I22,I33,Mx,My,Mz), [ti tf], IC, opts);
N = sqrt(sum(y(:,4:7).^2,2));
kap = acosd(1-2*y(:,5).^2-2*y(:,7).^2);
phi1 = acosd((2.*(y(:,4).*y(:,5)+y(:,6).*y(:,7)))/sind(kap));
phi2 = asind((2.*(y(:,6).*y(:,4)-y(:,5).*y(:,7)))/sind(kap));
if phi1==phi2
phi = phi1;
elseif phi1==180-phi2
phi = phi1;
elseif -phi1==phi2

end

end
My lines where I calculate phi1, phi2, and then the if/else statement to find phi, are what I am struggling with.
I made sure that the variables defined in the function work, so for example, in the command window I typed in 'y(:,4)' and got the correct output. But whenever I try to use this within the functions i.e. 'phi1', it repeatedly outputs an incorrect value of '90.0000' until I stop it.
Where I define the 'N' variable, it is something similar, yet that one works without errors.
Does anyone have any ideas how to amend this issue?
Any help is appreciated, thanks.
Edit: The complete error message is as follows:
Undefined function or variable 'phi'.
Error in HW6_Q1 (line 85)
plot(t,phi)
I figured out my solution with the help from a colleague not on Stack Overflow.
I forgot the ./, which turned my phi into a matrix, rather than a vector which is what I wanted from it.
i'm trying to implement this code. here are the problems:
1. i want to use variable typ_transport in further coding not just inside if.(it does not recognize the variable.)
2. the logic seems to be right but when i change the values in jsonStr (e.g. "walk" : true to "walk" : fasle ) the output does not print the right output.
Could any one help me with this? thanks
import json
jsonStr = '{"walk" : true, "bike" : false, "tram" : false}'
inputvar = json.loads(jsonStr)
if inputvar['walk'] == 'True' and inputvar['bike'] == 'False' :
typ_transport='foot'
elif inputvar['walk'] == 'False' and inputvar['bike'] == 'True' :
typ_transport='bicycle'
class transport:
if typ_transport=='foot':
velocity=80
typ='foot'
elif typ_transport=='bicycle':
velocity=330
typ='bicycle'
def __init__(self,typ,velocity):
self.velocity = velocity
self.typ = typ
if inputvar['tram'] == 'False' :
radius= T*transport.velocity
print (radius)
else :
print (typ_transport, 333)
I see some problems in the code, so I'll try to point them out as I go through your questions
i want to use variable typ_transport in further coding not just inside if.(it does not recognize the variable.)
The reason why you can't access the typ_transport variable is that it's created inside the if statement. If you wish to access the variable later in the code, you would have to change the scope of the typ_transport into a global scope.
You can do this in two ways. First is creating a global variable before you start the if statement
typ_transport = ""
if inputvar['walk'] == True and inputvar['bike'] == False:
typ_transport = 'foot'
The second way would be to create a global variable inside the if statement using global keyword. This way is highly discouraged since it is easy to lose the track of variables and their scopes.
the logic seems to be right but when i change the values in jsonStr (e.g. "walk" : true to "walk" : fasle ) the output does not print the right output
Aside from the spelling errors you got there, Python booleans are kept in True, and False (no single quote, first letter capitalized). When you use JSON module, it should parse correctly, but it's always good idea to double check.
Lastly, You are using class but it's not organized. Let's try to make it look little more tidier.
class transport:
def __init__(self,typ_transport): #utilizing global variable we created
if typ_transport == 'foot':
velocity = 80
self.typ_transport = self.typ_transport
self.velocity = velocity
elif typ_transport == 'bicycle':
......
Now to get the velocity when typ_transport = 'foot'
passenger = transport(typ_transport) #creating passenger object
velocity = passenger.velocity
import json
jsonStr = ('[{"walk" : true, "bike" : false, "tram" : false}, '
'{"walk" : false, "bike" : true, "tram" : false}, '
'{"walk" : false, "bike" : false, "tram" : true},'
'{"walk" : false, "bike" : false, "tram" : false}]'
)
inputvar = json.loads(jsonStr)
class Transport:
def __init__(self,typ):
self.typ = typ
self.velocity = None
if typ == 'foot':
self.velocity = 80
elif typ == 'bicycle':
self.velocity = 330
elif typ == 'tram':
self.velocity = 333
for var in inputvar:
typ_transport = None
if var['walk'] is True and var['bike'] is False:
typ_transport = 'foot'
elif var['walk'] is False and var['bike'] is True:
typ_transport = 'bicycle'
elif var['tram'] is True:
typ_transport = 'tram'
transport = Transport(typ_transport)
print(transport.typ, transport.velocity)
This make more sense to me.
Feel free to change it, if I misunderstood your logic.
I'm learning programming in computercraft (minecraft) and having some trouble with reading some storage cells.
The function that I'm working on shall go through all cells and add together the storage capacity to a variable in a for loop.
This is what I got so far
local cell1 = peripheral.wrap("tile_thermalexpansion_cell_reinforced_name_2")
local cell2 = peripheral.wrap("tile_thermalexpansion_cell_reinforced_name_3")
local cell3 = peripheral.wrap("tile_thermalexpansion_cell_reinforced_name_4")
local cell4 = peripheral.wrap("tile_thermalexpansion_cell_reinforced_name_5")
local cell5 = peripheral.wrap("tile_thermalexpansion_cell_reinforced_name_6")
local cell6 = peripheral.wrap("tile_thermalexpansion_cell_reinforced_name_7")
cells = {"cell1", "cell2", "cell3", "cell4", "cell5", "cell6"}
local totStorage
function getTotStorage(table)
for key = 1,6 do
x = table[key]
totStorage = totStorage + x.getMaxEnergyStored()
end
print(totStorage)
end
I get an error on this line
totStorage = totStorage + x.getMaxEnergyStored()
saying "Attempt to call nil".
Any suggestions?
cells = {"cell1", "cell2", "cell3", "cell4", "cell5", "cell6"}
Is shorthand for:
cells = {
-- key value
[1] = "cell1",
[2] = "cell2",
[3] = "cell3",
[4] = "cell4",
[5] = "cell5",
[6] = "cell6"
}
Assuming that your getTotStorage call is similar to below (you didn't post it)
getTotStorage(cells)
In the loop you try to call a method on x which is a string value:
for key = 1,6 do
x = table[key]
totStorage = totStorage + x.getMaxEnergyStored()
end
This is essentially trying to do:
totStorage = totStorage + ("cell1").getMaxEnergyStored()
What you could do is rearrange your code so that the values are the objects returned by peripheral.wrap:
local cells = {
peripheral.wrap("tile_thermalexpansion_cell_reinforced_name_2"),
peripheral.wrap("tile_thermalexpansion_cell_reinforced_name_3"),
peripheral.wrap("tile_thermalexpansion_cell_reinforced_name_4"),
peripheral.wrap("tile_thermalexpansion_cell_reinforced_name_5"),
peripheral.wrap("tile_thermalexpansion_cell_reinforced_name_6"),
peripheral.wrap("tile_thermalexpansion_cell_reinforced_name_7"),
}
function getTotStorage(t)
local totStorage = 0
for i,v in ipairs(t) do
totStorage = totStorage + v.getMaxEnergyStored()
end
print(totStorage)
end
A few observations:
Use local when you can (i.e. totStorage) to limit the scope of a variable (no need to have a loop counter as a global)
Don't name variables that collide with the standard Lua library (i.e. string, table, math)
ipairs is a better way to loop through a sequence
Is it possible to insert or save an image to a database table using MatLab?
Here's my code:
%Code for Database Login
conn = database('vlmsystem','admin','vlog');
indata = imread('C:\Users\Sony Vaio\Documents\Task\0.1 Systems\System 1 - edited\Appendix\images database\auto1.jpg');

indata = a.cdata;
hgsave(h, 'tempfile.fig')
fid = fopen('tempfile.fig', 'r')
indata = fread(fid, inf, '*uint8')
fclose(fid)
s = size(indata);
bdata = reshape(indata,[],1);
x = conn.Handle
StatementObject = x.preparestatement(insertcommand);
StatementObject.setObject(1,bdata)
StatementObject.execute
close(StatementObject)
dbpath = 'C:\Users\Sony Vaio\Documents\Task\0.1 Systems\System 1 - edited\Appendix\vlogdbase.mdb';
tableName = 'vehicleLog';
colnames = {'date_time','plate_number','login_logout','physical_feature'}

pltno = (f);
lilo = 'login';
physf = {bdata}
coldata = {dat,pltno,lilo,}
insert(conn,tableName,colnames,coldata);
close(conn);
And I am getting this error.

EDIT: Fix Code....but... how to insert binary data into the database.
There's no binary option in the database. The result won't feed into the table.

The solution says:
Alternatively, if you have a figure and want to save a snapshot of it, use the command below:
You copied both blocks, one that reads files, one hat uses getframe to read a frame from a handle.
