When I bind a function to a button inside an accordion nothing happens upon clicking it. I have no idea what i'm doing wrong. :( Any thoughts?
def printTest():
print "The button worked!"
accord = Accordion(anim_duration=1.5, orientation='vertical')
specialButton = Button(text="click me", font_size='20sp', text_size=(1100, None), halign="center")
specialButton.bind(on_press=printTest():
item = AccordionItem(title="Hello World")
item.add_widget(specialButton)
accord.add_widget(item)
specialButton.bind(on_press=printTest():
This isn't valid syntax, is the colon a typo?
Either way, the problem is that you are calling printTest, not passing it as an argument.
Instead try
def printTest(*args):
print "The button worked!"
...and...
specialButton.bind(on_press=printTest)
The *args is important because the binding automatically passes some arguments.
I covered this in more detail here.

function teleportTo(placeCFrame)
local plyr = game.Players.LocalPlayer;
if plyr.Character then
return plyr.Character.HumanoidRootPart.CFrame = placeCFrame;
end
end
teleportTo(game:GetService("Workspace").game:GetService("Workspace").Zeppelin.FuelTank1.Tank.CFrame)
my code is here, idk much about coding thanks for helping
and if you told me how to make the player teleport to a moving object it would be so super
The error is telling you what is going on.
When the code was being interpreted line by line, it expected the next symbol to be end, but instead it got =.
That means that something about how you're using the equals sign is incorrect. So when we look at the line :
return plyr.Character.HumanoidRootPart.CFrame = placeCFrame
You cannot assign a value on the same line as a return command. return is used to pipe a value out of a function so it can be used where the function was called.
But I'm pretty sure that isn't what you intended, you just want to set a player's position. So to fix your issue, remove the return.
if plyr.Character then
plyr.Character.HumanoidRootPart.CFrame = placeCFrame
end
The reason you are getting an error is because = is usually defined as setting a value, and no code can be executed after a return or it will error
If you wanted to, you could add return after all the code is done executing
could someone help me with this error?
I have a button created called "TextButton" and I have a text called "TextLabel", what I need to do is make the "TextLabel" increase by 1 when I press the "TextButton" button, could someone help me with this please.
function script.Parent.MouseButton1Click:Connect(function()
print("working..?..")
script.Parent.ValorVoto.Value = script.Parent.ValorVoto.Value+1
script.Parent.Parent.TextLabel = "clicks: "..script.Parent.ValorVoto.Value
end
script.Parent.Parent.TextButton.MouseButton1Down:Connect(clicking)
I think you've got a syntax error. It looks like you're defining a function, but also trying to connect that function immediately to the TextButton. Try naming your function clicking, and then passing that into the connection.
function clicking()
print("working..?..")
local vv = script.Parent.ValorVoto
vv.Value = vv.Value + 1
script.Parent.Parent.TextLabel.Text = "clicks: " .. tostring(vv.Value)
end
script.Parent.MouseButton1Click:Connect(clicking)
You have 2 errors in this script:
Line 4, add a .Text after referencing the TextLabel.
As Kylaa said, there is an error with line 7, you can just get rid of that line because your function was called with an event already. You don't need to recall that function, plus the function you're trying to call doesn't exist.
You don't mark it as a function if it's already listening for an event.
script.Parent.MouseButton1Click:Connect(function()
print("working..?..")
script.Parent.ValorVoto.Value = script.Parent.ValorVoto.Value+1
script.Parent.Parent.TextLabel.Text = "clicks: "..script.Parent.ValorVoto.Value
end
I'm a complete newbie to both Lua, PICO-8, and coding in general. I'm having trouble with a function I want to put in my first program. The text is all placeholder, I will change it once I get the code right and comprehend it.
Basically, before the _init() I have a function ow() defined where I press a button and the program displays the text "ow." I put the function name in _update() so that it will update 30x/second to see if the button is pressed; however, this is making the "ow" appear 30 times a second (or however long the button is pressed) instead of appearing once when I initially press the button. How do I fix this? Thank you for your tolerance of a new coder's question in advance. Here's my code:
function ow()
if btn((X))
then print "ow"
--how do i make it do this
--only once?
end
end
function _init()
print "hello."
print "i have been waiting for you."
end
function _update()
ow()
end
function _draw()
end
You need a global variable to save previous status of the button.
function ow()
if btn((X)) then
if not button_was_pressed then
button_was_pressed = true
print "ow"
end
else
button_was_pressed = false
end
end
I am using the IUP.GetParm dialog to do a search and replace prompt.
The dialog supports 3 buttons, the first two OK and Cancel close the prompt and return to the main program flow.
The third button can be tracked in the parm_action function, what I want to do is use the third button to skip the item and close the dialog, but I can't work out if this is possible.
I have asked this on the IUP mailing list but have not yet had a response.
function param_action(dialog,index)
if index == -4 then
bSkip = true
return 1
end
end
bSkip = false
bConfirm,strFromString,strToString,bSkip =
iup.GetParam("Search and Replace",
param_action,
fhGetTag(ptrRecord)..'-'..fhGetTag(ptr)..
' '..fhGetDisplayText(ptrRecord).." %t\n"..
"Replace: "..strBoxType.."\n"..
"With: "..strBoxType.."\n"..
"btn: %u[Ok,Cancel,Skip] \n"
, strFromString,strToString)
if bConfirm and not(bSkip) then
-- replace string
end
To make this function currently you have to press the Skip button and then the Ok button.
Just re-posting the answer from the IUP mailing list here:
Inside the call-back, when the 3rd button is pressed, set the dialog
attribute "status" to "1" and call the function iup.ExitLoop().
I'm working with an example that I can't understand what the braces do -- the ones around the "Logout" in the second "out" statement below. I guess the string is passed as a closure but I'm not getting the syntax beyond that. Can you please clarify? Note the output of the code looks like the following:
John Doe [Logout]
class LoginTagLib {
def loginControl = {
if(request.getSession(false) && session.user){
out << "Hello ${session.user.login} "
out << """[${link(action:"logout",
controller:"user"){"Logout"}}]"""
} else {
out << """[${link(action:"login",
controller:"user"){"Login"}}]"""
}
}
}
Thanks Much
The link tag takes attributes and a body, and as a regular GSP tag it's called like this:
<g:link action="logout" controller="user">Logout</g:link>
To invoke it as a method like you're doing, you need a way to pass the text ('Logout') to render in the link. If you look at the source of the tag (click "Show Source" at the bottom of http://grails.org/doc/latest/ref/Tags/link.html) you'll see that the 2nd argument is body, and it's a Closure (although that's not clear from the code, but that's always the case for 2-parameter tags). {"Logout"} is a Closure that returns "Logout" since it's the last expression, so it's used as the body.
Actually the output should be
Hello John Doe [Logout]
Essentially, if there is a session and a user write Hello user and create a link pointing to a logout action with the label Logout.
{ "Logout" } is a closure equivalent to { return "Logout"; } as the last statement is used for a return value if none is explicitly stated.
I am not able to get the output like below
Hello John Doe [Logout]
Here is the output I am getting
Hello jdoe [Logout
