I am trying to insert an animation into my code for the first time. Here is my code:
1 local player = game.Players.LocalPlayer
2 local char = player.Character or player.CharacterAdded:Wait()
3 local hum = char:WaitForChild("Humanoid")
4
5 local animaInstance = Instance.new("Animation")
6 animaInstance.AnimationId = "rbxassetid://4641537766"
7
8 local fireBallAnim = hum.LoadAnimation(animaInstance)
9 fireBallAnim:Play()
I am getting the error
The function LoadAnimation is not a member of Animation
I know the character has fully loaded, so I don't understand. Could I be getting this error if there is something wrong with the animation itself? What else am I missing out?
Thanks
local fireBallAnim = hum:LoadAnimation(animaInstance)
This is a very confusing message for the error. The only problem is that you've called a member function with a . as opposed to a :. Switching it to a colon will fix your error.
When you call a function on an object with a colon, it is automatically inserting the object as the first argument. A fun example of this can be seen with tables :
-- insert an object into the table 't'
local t = {}
table.insert(t, 1)
-- can also be written as...
t.insert(t, 1)
-- which is the same as...
t:insert(1)
All of these calls do the same thing. Calling the function with : is syntactic sugar for putting the t object as the first argument. So in your code, what's happening is you are calling LoadAnimation like this :
local fireBallAnim = hum.LoadAnimation(<a humanoid object needs to go here>, <animation>)
But since you are passing in the animation where the Humanoid is supposed to go, it is trying to find the LoadAnimation function on the animation object and failing.

I passed an object in a function in laravel.
I tried to assign the value of a property to a variable. It pops an error.
When I tried to figure out what was going on I tried to dd ()the value it worked.
But when I tried to echo the same it does not.
What am I mising.
On using this,
location1 and location2 are two objects of the location class.
The function is here:
function geodistance($location1,$location2){
dd($location1->lat);
$lat1=$location1->lat;
}
it prints
"28.612072"
But when I change the same function to
function geodistance($location1,$location2){
echo($location1->lat);
$lat1=$location1->lat;
}
The output error is:
Trying to get property 'lat' of non-object
Even the function
function geodistance($location1,$location2){
echo $location1->lat;
$lat1=$location1->lat;
}
gives the same output
The aim to remind you is to assign the value to a variable like so.
function geodistance($location1,$location2){
$lat1=$location1->lat;
}
When I echo $location1 from within the function geodistance() gives out and error which makes sense.
function geodistance($location1,$location2){
echo $location1;
$lat1=$location1->lat;
Object of class App\MyClasses\city could not be converted to string
When I dd ($location1 from the funciton like so it gives the right result.
function geodistance($location1,$location2){
dd($location1);
$lat1=$location1->lat;
like so:
city {#13410 ▼
+id: 2245
+info: "{}"
+name: "New Delhi"
+lat: "28.612072"
+lon: "77.22978"
+timezone: null
+weightedrating: null
+country_id: 1
}
It seems i am missing out something very trivial. :(
As pointed out by #salman zafar and #apokryfos, the mistake was that I was passing an array.
When I was doing a dd, after processing the first data the programme was terminated.
The array that was passed was not completely correct. The last data point in my array was not an object of the same class.
So the data ended up being corrupted when using echo. Echo would print one data after another but eventually it would get a wrong input.
The best way to catch these errors (after so much experimenting) is to write the values of the variable in a text file on each iterartion.
What that does is that it catches the error in your text file and u get to know after how many iterations the programme stopped.
Hope this helps others from making such obviously glaring mistakes which are tough to catch (atleast for me since this was the first of such errors)
I'm using a script exactly like the one on the tutorial here, https://developers.google.com/apps-script/reference/ui/file-upload
However, despite using the syntax I keep getting e is undefined in the statement:
var fileBlob = e.parameter.dsrFile;
I think that means my function doPost(e) is probably wrong somehow. Here is my entire script below.
// Create Menu to Locate .CSV
function doGet(e) {
var app = UiApp.createApplication().setTitle("Upload CSV");
var formContent = app.createVerticalPanel();
formContent.add(app.createFileUpload().setName("dsrFile"));
formContent.add(app.createSubmitButton("Start Upload"));
var form = app.createFormPanel();
form.add(formContent);
app.add(form);
return app;
}
// Upload .CSV file
function doPost(e)
{
// data returned is a blob for FileUpload widget
var fileBlob = e.parameter.dsrFile;
var doc = DocsList.createFile(fileBlob);
}
e is undefined because you are not passing anything to doPost. You have to pass the needed object to doPost. Check where you call the function and what parameters do you pass to it if any. Even if you pass a parameter to that function, it holds undefined value. Make sure that you are passing the correct objects to your functions.
Your script should work perfectly. e is defined by Google Apps Script, not need to pass anything in particular is contains the fields of your form, in particular in this case the file you uploaded.
I would suspect you may be falling foul to the dev url vs publish url syndrome, where you are executing an old scrip rather that the code you are currently working on.
Be sure you script end with 'dev' and not 'exec'
https://script.google.com/a/macros/appsscripttesting.com/s/AKfyck...EY7qzA7m6hFCnyKqg/dev
Let me know if you are still getting the error after running it from the /dev url
I wish to have a method that takes in a string, and then updates a variable with the name of that string. This is an example of my attempt:
#other_class = OtherClass.new()
def change_variable(variable_string)
self.#other_class.send.variable_string += 1
end
I am getting the error:
syntax error, unexpected tIVAR
with the pointer just before 'send' in the method above. Does anyone have any suggestions to make this work?
You probably want instance_variable_set http://ruby-doc.org/core-2.0/Object.html#method-i-instance_variable_set
The syntax using your variables is I think:
other_var = ('#' + variable_string).to_sym
#other_class.instance_variable_set( other_var, #other_class.instance_variable_get( other_var ) + 1 )
The immediate syntatic error is that you're using self and # wrongly.
Either one is fine but not in conjunction with each other.
So in your case self.other_class.send... would be fine but then you cant declare it as #.
As would # be but then you cant do self.
These are meant to do different things and these are that
# is an instance variable and so is self but the difference is that using # calls the attribute other_class directly as to where self calls the method other_class.
So # is both a getter and setter in one so you can do
#other_class = my_milk_man as to where
self.other_class -> self.other_class (as getter),
self.other_class = my_milk_man -> self.other_class= (as setter).
In my game, I have an __init__ function which creates a set of seven entry boxes, like so:
self.string1 = StringVal()
self.entry1 = Entry(frame, textvariable = self.string1).grid(row = 4, column = 1, sticky = W)
This is copied six more times. This works.
At the end of the game, though, I want to delete the Entry box's text, using this code I found several places online:
self.entry1.delete(0, END)
I also tried using something else I found:
if self.entry1.get():
self.entry1.delete(0, END)
These both say that self.entry1 is a NoneType object, and has no method .get() or .delete(). Just to try things out, I substituted self.entry1.get() and self.entry1.delete(0,END) with self.string1.get(), etc. I also tried substituting .delete(0, END) with .delete(0.0, END). Neither of these worked either. I do not understand what I am doing wrong.
Thanks for your help!
When you do something like this:
self.foo = Button(...).grid(...)
... Then what gets stored in self.foo is the result of the call to grid(). This will always be None. You need to separate your widget creation from the loyout in order to save a reference to the created widgets.
I'm getting this exception in this code:
Dim TSV As TimeScaleValues
TSV = ActiveProject.Task(ntask).Resources(nresource).TimeScaleData(nStartDate , nEndDate, PjResourceTimescaledData.pjResourceTimescaledActualWork, PjTimescaleUnit.pjTimescaleDays, 1)
TSV.item(1).Add( nMinutes , 1 ) ' nMinutes is the value of time in minutes. The error occours in this line !!!!
When I execute the last line I get this exception
Invalid value for argument.
Error code -2146827187
{Microsoft.Office.Interop.MSProject.TimeScaleValue Add(System.Object, System.Object)}
The estrange thing is that I got this example right from this microsoft reference page.
What I'm trying to do is add a time to time scale on project.
I solved the problem.
I was setting the value in the wrong place.
Seems confuse, but I was trying to get the time scale value from resource, but the right place to set the values is on assignments.
I was doing this..
TSV = ActiveProject.Task(ntask).Resources(nresource).TimeScaleData...
The right code is like:
TSV = ActiveProject.Assignments.TimeScaleData..
For each resource in the task is created one assingment, so teh final code is like:
For Each assignment As Assignment In Task.Assigments
if assignment.Resource.WindowsUserAccount = <desiredAccount> then
tsv = assingment.TimeScaleData..
end if
