Basically you need to switch mouse events with touch events inside that class, so mosue events are stopped and touch events execute click event.

Check this thread for more info:

Or alternately you can check this library:

Hmm, yes you need to handle touches based on their ids or it seems that while one touch happens, other automatically takes off the focus of the button.

This events seem to work for me:

function Button:onMouseDown(event)
	if self:hitTestPoint(event.touch.x, event.touch.y) then
		self.focus = event.touch.id
		self:updateVisualState(true)
	end
end
 
function Button:onMouseMove(event)
	if self.focus == event.touch.id then
		if not self:hitTestPoint(event.touch.x, event.touch.y) then	
			self.focus = false
			self:updateVisualState(false)
		end
	end
end
 
function Button:onMouseUp(event)
	if self.focus == event.touch.id then
		self.focus = false
		self:updateVisualState(false)
		self:dispatchEvent(Event.new("click"))	-- button is clicked, dispatch "click" event
	end
end
