I am trying to add an attirubute to objects that i created.Here i created bird display objects but i want to add those birds a spesific attiribute like typeOfBird and then i want to reach those attiributes like bird.typeOfBird . How can i do that?
module(...,package.seeall)
function new(params)
local bird=display.newImage(params.img,params.x,params.y)
function bird:touch(event)
local t = event.target
local phase = event.phase
if "began" == phase then
-- Make target the top-most object
local parent = t.parent
parent:insert( t )
display.getCurrentStage():setFocus( t )
t.isFocus = true
elseif t.isFocus then
if "moved" == phase then
t.x = event.x
t.y = event.y
elseif "ended" == phase or "cancelled" == phase then
display.getCurrentStage():setFocus( nil )
t.isFocus = false
end
end
return true
end
It looks like bird objects are already simple lua tables,
so you can just get and set the values as normal. So for example you could add lines like:
if self.typeOfBird == "gull" then ... end
and
self.typeOfBird = "parrot"
to your bird:touch function.
Or
bird.typeOfBird = "gull"
in your new function.

Context:
I click on a button -> a WindowDialogue appears -> there are 2 LineEdit Nodes and a button
Supposed procedure:
I fill these LineEdits, press the button, and the function tied to the button receives the texts from the LineEdits (and creates a dictionary key-value pair).
Problem:
The texts from the LineEdits do not pass down to the function (through connect()).
I tried passing the text directly with LineEdit.text. I tried writing it in a different variable and passing the variable. The debug shows the function is getting executed (no problem with that), but the strings passed from the LineEdits are always empty. Somehow, it worked for some time when I explicitly pressed ENTER after filling the LineEdits. But after I tried to fix the aforementioned problem, it stopped working altogether.
P.S. Everything I mentioned is created dynamically through the code, if that matters.
Code:
#Declaring the variables
var temp_text_key = ""
var temp_text_value = ""

You mentioned using 'LineEdit.text', but have you tried the following?
var text = LineEdit.get_text()
If this doesn't help, please update your original post to include code examples.
I can try to set condition some data that is within the time picker in the datepicker. I got two problem
MY code was
def show_filter_date(start ,end):
print(start_dater.value)
print(end_dater.value)
time_df = (id_one[(id_one['_source.timestampstring']>pd.to_datetime(start))&(id_one['_source.timestampstring']<pd.to_datetime(end))])
#print(time_df.head(20))
# time_df = (id_one[(id_one['_source.timestampstring']>pd.to_datetime(start_dater.value))&(id_one['_source.timestampstring']<pd.to_datetime(end_dater.value))])
time_df.head(20)
layout = widgets.Layout(width='auto', height='40px')
start_dater = widgets.DatePicker(description='Pick a Start Date',disabled=False)
end_dater = widgets.DatePicker(description='Pick an End Date',disabled=False )
#display(widgets.HBox((start_dater, end_dater)))
#display(start_dater)
#display(end_dater)
#id_one.head()
#combine_date = widgets.HBox((start = start_dater, end = end_dater))
#country_selector = widgets.Dropdown(
interact(show_filter_date,start = start_dater , end = end_dater)
everytime i run the code it show Error
"Invalid comparison between dtype=datetime64[ns] and NoneType"
I have tried to assign default value like
start_dater = widgets.DatePicker(description='Pick a Start Date',disabled=False, year = 2020 ,month = 12, day = 1)
but it won't change to 2020/12/01
So, how can I get a value other than null?
I fail in interact for the datepicker in which
A) print(time_df.head(20))
B)
time_df = (id_one[(id_one['_source.timestampstring']>pd.to_datetime(start_dater.value))&(id_one['_source.timestampstring']<pd.to_datetime(end_dater.value))])
time_df.head(20)
Only (A) can be "interact" or "refresh" when I pick a day but not (B)
And for Question 2, when I put time_df.head(20) in the NEXT CELL it does work tho.......
But what i want is to show the result like in time_df
I would appreciate if any help
the id_one is something like
Index _source.hdrrId _source.hdrfId _source.hdrType \
199 1300 1234 1
_source.timestampstring
199 2020-11-06 09:36:04.800
Thanks!
Jeff
I replicated your first error with
id_one = pd.DataFrame(pd.date_range('20200101','20200202'), columns = ['_source.timestampstring'])
This is because you did not set a default value for the DatePicker. The value is None by default hence the error. Here is the fix (value argument is the default value):
start_dater = widgets.DatePicker(description='Pick a Start Date',disabled=False, value = datetime.date(2020,1,1))
end_dater = widgets.DatePicker(description='Pick an End Date',disabled=False, value = datetime.date(2020,2,1))
I cannot replicate your second error. My guess is you put print before the time_df = statement. You need to put the print after the line that calculates time_df
I have this function who supposed to change the label of polygon (code below), where "nom_com" and "statutpro" are fields in a layer.
def ETIQUETAGE(self):
layer = self.COUCHE_DEPARTEMENT_SELECTIONNEE() #return a vector layer
deco = QgsPalLayerSettings()
deco.enabled = True
isExpression = True
if self.ChoixEtiquetage.currentText() == "COMMUNE":
deco.fieldName = '\'nom :\' +"nom_com"'
if self.ChoixEtiquetage.currentText() == "COMMUNE ET STATUT PROSPECTION":
deco.fieldName = '"nom_com" + \'\\n\' +"statutpro"'
labeler = QgsVectorLayerSimpleLabeling(deco)
layer.setLabeling(labeler)
layer.setLabelsEnabled(True)
layer.triggerRepaint()
When I run it everything ok (i don't have any error), the problem is for the display. The function change the label charateristic in the properties window but there is no display until I press aply in the properties window.
When I put only one argument the display work perfectly. for example
deco.fieldName = "nom_com"
Is there a particular syntax when it's a expression ?
I just see where my error was, it was a syntaxe error.
If the label is expression based we must put
deco.isExpression
for the plugin to display something in the canvas
def ETIQUETAGE(self):
layer = self.COUCHE_DEPARTEMENT_SELECTIONNEE() #return a vector layer
deco = QgsPalLayerSettings()
deco.enabled = True
deco.isExpression = True
if self.ChoixEtiquetage.currentText() == "COMMUNE":
deco.fieldName = "concat('nom : ', nom_com)"
if self.ChoixEtiquetage.currentText() == "COMMUNE ET STATUT PROSPECTION":
deco.fieldName = "concat('nom : ', nom_com, '\\n', 'Statut prospection : ', statutpro)"'
labeler = QgsVectorLayerSimpleLabeling(deco)
layer.setLabeling(labeler)
layer.setLabelsEnabled(True)
layer.triggerRepaint()
hope it will help people
I want to got First line of the function goToSignUpActivit() if isAllInputValid == False
from CustomUtil import *
from Register import *
def goToSingUpActivity():
fName = input("Enter your First Name:")
lName = input("Enter your last name:")
mobileNum = input("input your mobile number")
role = input("Select your role s: for staff p: for patient:")
isFNameValid = validateInput(fName)
isLNameValid = validateInput(lName) // this function in CustomUtil package
isRoleValid = False
if (role in ["s","p","S","P"]):
isRoleValid = True
isMobileNumValid = validateMobilNum(mobileNum)// this function in CustomUtil package
isAllInputValid = False
if (isFNameValid and isLNameValid and isRoleValid and isMobileNumValid) :
isAllInputValid = True
if (isAllInputValid) :
isAllInputValid = True
if role in ["s","S"]:
registerAsStaff(fName,lName,mobileNum)// this function in Register package
return
elif role in ["p","P"]:
registerAsPatient(fName,lName,mobileNum)// this function in Register package
return
while(not isAllInputValid):
if(input("you want to exit y or n:") in ["y","Y"]):
return
goToSingUpActivity()
Above code put goToSingUpActivity() into the stack while isAllInputValid become true.
After I enter all input correctly stack pop goToSingUpActivity() one bye one.
What I need here is after isAllInputValid becomes true, clear all goToSingUpActivity() from stack.
If above solution not possible, is there any other way to modifie the code?
Edit: I got a solution by making isAllInputValid global and put the while loop outside the function after calling goToSingUpActivity().
You can use a while statement (WARNING to don't create a while(true), give to the user an opportunity to cancel his action !).
def goToSingUpActivity():
isAllValid = False
while(!isAllValid):
#your inputs stuff
if(isFNameValid and isLNameValid and isRoleValid and isMobileNumValid):
isAllValid = True
#rest of the function
I have multilevel game and all my objects stay 'empty' in memory between levels
what i mean is that if I set physics to hybrid, when i come again in the level, (or another level) it shows a box but without the picture. (and physics act on these empty boxes)
in the destroyScene I have made sure they are all
myObj:removeSelf()
myObj = nil
and i print a message to prove that it actually does it.
Also in the menu in the enterScene, just in case I do a
local prior_scene = storyboard.getprevious()
storyboard.purgescene( prior_scene )
and also tried a
storyboard.removeAll()
and even a
storyboard.purgeOnSceneChange = true
nothing works when i go to the next level, or into the same level again, all my previous objects are still here, I just don't get it
ok, it's gonna be a bit long but here the entire level. it does go through the destroyscene but somehow the display objects are not removed.

Hi #DevfaR
Ha, I have restarted from scratch with the corona template and figured out a few things:
1) the exitScene/destroyScene actually does something if the local group is used to group display objects. it removes the display group !
not really obvious as there is only one declaration in it, no code as such
2) the reason why I had so much of removeSelf of objects all over the place is because nothing was working. So I tried pretty much everything under the web.
3) And the reason why it didnt work is because I was creating my display objects into a function. and somehow the display group is not passed there. if I move the code into the createScene function then indeed it is all cleared up when going to the next scene.
problem is .. I really would like to group my puppetCreation code !
e.g.
function scene:createScene( event )
local group = self.view
local physics = require("physics")
physics.start()
background = display.newImage("assets/bckg.png",0,0)
group:insert(background)
createPuppet1(group)
createPuppet2(group)
end
function createPuppet1(group)
puppet1= display.newImage("assets/puppet1.png",0,0)
group:insert(puppet1)
end
function createPuppet2(group)
puppet2= display.newImage("assets/puppet2.png",0,0)
group:insert(puppet2)
end
I passed (group) because the function createPuppet doesnt let me specify
local group = self.view
my email address is edualczatebed#gmail.com
thank you for your help
there's a lot of bug in your code the way you implement it is not good because when you go to a scene and then you switch to another scene your removing all of the object on the destroyScene together with it's listener which is not very efficient i cannot point out what's causing the problem because like i said there is a lot of bug in your code. i think you didn't quite understand how to use a storyboard on Corona. to give you an idea on how will you solve your problem i will implement some code for you to understand that even if you do not remove the object on destroyScene you can remove the object via it's on display groups.
local rectangle
local circle
local function nextScene(event)
storyboard.gotoScene( "scene_2", "fade", "500")
end
-- Called when the scene's view does not exist:
function scene:createScene( event )
local group = self.view
-----------------------------------------------------------------------------
rectangle = display.newRect(100,100,100,100)
rectangle:setFillColor(255,0,0)
rectangle.x = 100
rectangle.y = 100
circle = display.newCircle(100,100,50)
circle.x = 250
circle.y = 100
circle:setFillColor(0,255,0)
--inserting all of your object into display group so that if you destroy the scene the display group will be remove
group:insert(rectangle)
group:insert(circle)
-----------------------------------------------------------------------------
end
-- Called immediately after scene has moved onscreen:
function scene:enterScene( event )
local group = self.view
-----------------------------------------------------------------------------
rectangle:addEventListener("tap", nextScene)
circle:addEventListener("tap", nextScene)
-----------------------------------------------------------------------------
end
-- Called when scene is about to move offscreen:
function scene:exitScene( event )
local group = self.view
-----------------------------------------------------------------------------
-----------------------------------------------------------------------------
end
-- Called prior to the removal of scene's "view" (display group)
function scene:destroyScene( event )
local group = self.view
-----------------------------------------------------------------------------
-----------------------------------------------------------------------------
end
as you can see i create 2 object the rectangle and circle after i created the objects insert it to group then on enterScene i added a tap listener which will go to the second scene if i tap the object. notice that i didn't bother to remove the object and listener on destroyScene when i go to the scene_2 that is because when i insert the object to the display group whenever i change the scene it will always remove the object. so after moving to the next scene you can either purged the last scene or completely remove it so when you get back to that scene it will recreate the object.
hope this can help you solve your problem
