joystick | DIY joysticks made from Raspberry Pi

Hello I am making radio controler for tank but I have problem with joystick code. Every time when I had same problem with ('JR' was not declared in this scope) in Serial.print('JR'); line. I don't have a lot of experince with arduino so it can be easy to solve problem. Can somebody help me? ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

I would like to know how to make the ADB adjust the accessibility focus while Talkback is on. I have tried:

I would like to learn about game development in Godot Engine. I'm trying to make a mobile game similar to the game Missiles:

Right now I have a functioning joystick. I get the value as a normalized Vector2:

I have an IoT device with BLE on it and also I have a smartphone which support BLE protocol. I am using RxAndroidBle: com.polidea.rxandroidble2:rxandroidble:1.11.1 The problem is to communicate each other. I have established connection:

I'm currently making a 2D game as a beginner and I wanted to add joystick controls to my game. I made everything like in the youtube video of Brackeys, but I always get this error:

So I've got a bluetooth connection from an arduino reading a joystick and sending the axis readout over bluetooth to my raspberry pi (4b running ubuntu 20.10). I've confirmed it's receiving this data too.

Now I try to run this bluetooth communcication in a separate process using the python multiprocessing module. to access the data from the arduino, I give the function a queue from the parent main process to put the data in there. Then in the main function I continuously try to read from this queue and process the data there.

The queue in the parent process always remains empty, however, and as such I can't process the data any further.

How can I get the data from the bluetooth process back to the main process?

I would like to preface this by saying I am still quite new to gameMakerstudio and I do not know all there is to know about how the software works and this is probably the root cause of my problem as I do not know why I am having this current layering issue.

I have been having an issue where I have TWO DrawGUI events in separate objects within the same room.

The first object is a Fog Of War that draws a GUI and reveals the map as the player moves, and keeps explored places visible but not in view.

The second object is the joystick where a player will use their thumb to drag the stick to move the player.

Ever since I have implemented the Fog of War. I have been unable to view the joystick. It appears that the fog of war draws overtop of it and I am unable to use it.

I understand there are other draw events where I can do this.

Draw Draw GUI Draw Begin Draw End Draw GUI BEGIN Draw GUI END

After changing where I have the code drawing. Example: At first the joystick and the fog were both in Draw GUI, After moving one from Draw GUI to Draw GUI Begin, the same issue appears.

I have made sure to place the joystick at the top most level in the room and the fog of war at the bottom most layer.

I have tried to apply depth the object

I am developing a 3D game with a custom chat console using Unity and UFPS, https://assetstore.unity.com/packages/tools/game-toolkits/ufps-ultimate-fps-106748

Everything is working, but running on Android TV with a joystick, keyboard and mouse we want to control which input affects what.

So we want the dialog to only be able to interact with the mouse. and the joystick to only interact with the game/player.

Original the mouse was controlling the players looking, and able to select the dialog. I was able to disable the mouse from controlling the player by,

Unity menu, Edit, Project Settings, Input

Then finding the "Mouse X" and Mouse Y" input events and renaming the ones with the mouse input to "Mouse XX", and leaving the joystick axis events for "Mouse X" so the joystick can still control the players looking.

Now I am having the opposite issue, the joystick and the arrow keyboard keys are toggling the selection in the dialog, and the joystick button/space key trigger selection in the dialog. I want to disable this so only the mouse can interact with the dialog and the joystick on controls the player movement.

I tried changing the Input for "Horizontal" "Vertical" by renaming to "Horizontal xxx". This works, but then the joystick is also not controlling the player movement. So how can I make these separate events. I cannot find any code listening to "Horizontal" or "Vertical" events, these seem to be hardwired in Unity some how??

My laptop runs a Python program that reads a joystick to send a speed command to an Arduino that in turn controls the motor on a toy car. To do that the program converts an integer with values between 0 and 255 to a single unsigned byte that it sends over a serial connection to the Arduino.

This code works to do that:
