Simultaneous tapping Virtual gamepad example (SOLVED)

**shadowmaikda** · November 26, 2019, 9:26pm

Hello

I tried using britzl’s virtual gamepad example, but I ran into a problem. When I tap simultaneously two points on the screen, the stick stops coming back.

(I do not tap on the screen)
Bug steps:

Tap simultaneously in different places.
Release the second point
Release the stick

Thanks in advance and sorry for my english if something is wrong wrote

Hmm, I thought I had updated it to support multi touch. Can you share a link to the example?

Please confirm that something like this works on your device with multitouch https://play.google.com/store/apps/details?id=com.the511plus.MultiTouchTester&hl=en_US

I downloaded here

I watched this source (it uses the same virtual gamepad example)

and in the source of the same bug

I have no problems with multitouch

Multitouch works on Android/iOS build, but does not work in html5. Where are you testing?

I believe @AGulev looked into this. Alexey, did you do any work on multitouch for HTML5?

maybe I do not explain correctly

multitouch works, but if i tap two points on the screen at the same time then there is a bug

I tried to check if the stick was released and when I saw the bug, then only one touch point was released (one message is released)
This only happens when the tap was at the same time. But I want to use it in my project.

Not really. I have it in my backlog for exploration day (not sure that it is possible to finish in exploration day. @sven knows input system better and could estimate this issue more accurate, I think).

As I understand, you are testing it in native (not html5) bundle?

I use apk on my android device

**britzl** · August 2, 2019, 6:27am

I found a problem in my example. I’ve pushed an update. @shadowmaikda, please try it again.

I also “productified” the on-screen controls into a reusable module:

github.com

britzl/defold-input/blob/master/in/onscreen.lua

local M = {}


M.BUTTON_PRESSED = hash("button_pressed")
M.BUTTON_RELEASED = hash("button_released")
M.ANALOG_PRESSED = hash("analog_pressed")
M.ANALOG_RELEASED = hash("analog_released")
M.ANALOG_MOVED = hash("analog_moved")

-- Create an instance of onscreen controls
-- @param config Optional table with configuration values. Accepted values are:
--		* touch (hash) Action id for the binding to single touch
-- @return instance
function M.create(config)
	config = config or {}
	config.touch = config.touch or hash("touch")

	local instance = {}

	local controls = {}

With example:

github.com

britzl/defold-input/blob/master/examples/onscreen/onscreen.gui_script

local onscreen = require "in.onscreen"

local post_to_listener

local function on_analog(action, control, touch)
	if action == onscreen.ANALOG_PRESSED then
		print("analog pressed")
		post_to_listener("analog", { x = 0, y = 0, pressed = true })
	elseif action == onscreen.ANALOG_RELEASED then
		print("analog released")
		post_to_listener("analog", { x = 0, y = 0, released = true })
	elseif action == onscreen.ANALOG_MOVED then
		print("analog moved")
		post_to_listener("analog", { x = touch.x, y = touch.y })
	end
end

local function on_control_a(action, control, touch)
	if action == onscreen.BUTTON_PRESSED then
		post_to_listener("button_a", { pressed = true })
