MouseButton1Down not working on mobile

Help and Feedback Scripting Support
#1

Hi DevForum,
I’ve encountered an issue. Basically, I’m making a Heel UI where you can customise Heels and weld them to your feet. That all works perfectly. My issue is that upon testing my colour wheel (I’ll send a picture below) doesn’t seem to work on mobile. This is both a studio and an in-game issue. I’m not sure of the cause, maybe I haven’t enabled something that should be, not sure. I don’t know if it’s worth sending the script as I’m pretty sure it’s got something to do with the properties of the colour wheel. It’s probably a stupid mistake I am prone to them.

you’re trying to use MouseButton1Down… on mobile… which doesn’t have a mouse?
that issue is quite self-explanatory.

#3

Oh I meant, MouseButton1Click. My apologise

#4

MouseButton1Down works on touch screen devices though.

Thats what I thought aswell, hmm

#6

hello,

more context is needed, please include your script.
can you also try using the mobile device under the test section in the top of studio, and see if the issue persists on there?

#7

Yeah of course. I also mentioned above that It was also studio bug, my apologise if I wasn’t clear enough

	)
	local H = (math.pi - math.atan2(ColourPickerCentre.Y - CentreOfWheel.Y, ColourPickerCentre.X - CentreOfWheel.X)) / (math.pi * 2)

	if DistanceFromWheel <= ColourWheel.AbsoluteSize.X/2 and ButtonDown then
		WheelPicker.Position = UDim2.new(0, MousePos.X - ColourWheel.AbsolutePosition.X, 0, MousePos.Y - ColourWheel.AbsolutePosition.Y)
	elseif MovingSlider then
		DarknessSlider.Position = UDim2.new(DarknessSlider.Position.X.Scale, 0, 0, 
			math.clamp(
			MousePos.Y - DarknessPicker.AbsolutePosition.Y, 
			0, 
			DarknessPicker.AbsoluteSize.Y)
		)	
	end
	updateColour(CentreOfWheel)
end)

I believe mousebutton1click works on mobile but it’s really hard for the event to register the user tapping. You’re likely better off using mousebutton1down

#10

Okay thank you so much, I’ll try now

#11

The problem seems to persist. Perhaps, the location of the UI could interfer with stuff like character movement, maybe it’s in the area where the moving joystick thingy is and stuff like that

#12

If it’s overlapping any of the primitive ui elements that may cause problems too

#13

Have you tried GuiButton.Activated instead?

#14

No I have not, I can try though.

#15

Yeah still the same issue, I think @Kurookku suggest might be the cause

#16

I think it could be this, I can try

EDIT: it doesn’t seem to be the issue…

#17

Did you try removing if input.UserInputType ~= Enum.UserInputType.MouseMovement then return end?

#20

Thank you so much. This wasn’t my script so I wasn’t that sure. Evidently, I hadn’t read through the script before making this post.

#21

It doesn’t work because moving your finger on the touchscreen isn’t considered MouseMovement. Use this:

UserInputService.TouchMoved:Connect(function()
    -- player drags finger on touch
end)
#22

It’s working for me, ummmmmmmm
