Unreal Engine mobile game

Step 1: Project and Folder Setup
Open Unreal Engine and create a new project.
In the Content Browser, create a new folder called “Core”.

Inside "Core", create the following Blueprints:

Character Blueprint (e.g., BP_Character)

Player Controller (e.g., BP_PlayerController)

GameMode Base (e.g., BP_GameMode)

Step 2: Configuring Blueprints
Open BP_PlayerController and assign it to your GameMode (BP_GameMode).

In BP_GameMode, set the Default Pawn Class to your BP_Character.

Compile each Blueprint (set it to always compile automatically).

Save your Level to the Core folder.

Step 3: World & Character Settings
In World Settings, override the GameMode and select your BP_GameMode from the Core folder.

Adjust your BP_Character:

Change the capsule component’s radius and height as needed.

Assign a Mesh to the character (choose an imported or default skeletal mesh).

Set the Animation Blueprint to an existing one (e.g., ABP_Bot) for idle/movement states.

Adjust the character’s mesh so it is properly aligned in the capsule.

Step 4: Mobile Movement with Joystick
In BP_Character, select the Character Movement component:

Enable “Orient Rotation to Movement”.

In BP_Character’s main Blueprint settings, turn OFF “Pawn Uses Controller Rotation Yaw” to prevent camera conflicts.

Setup the Event Graph:

On “Event Possessed”, cast to your BP_PlayerController.

From the controller, access the Enhanced Input Local Player Subsystem.

Add your input mapping context for mobile (usually called IMC_ThirdPersonControls).

On your input actions, create nodes for “Enhanced Input Action Move”.

Split the Action Value output into X and Y values.

Connect X and Y to “Add Movement Input” (X for right/left, Y for forward/back).

Use “Get Control Rotation”, split it, and connect right & forward vectors properly to control movement direction based on joystick position.

Step 5: Third-Person Camera Setup
Add a Spring Arm to your BP_Character and make it the root of your camera:

Set Target Arm Length and disable Collision Test.

Add a Camera as a child of the Spring Arm.

Reset camera rotation to (0,0,0) for a neutral view.

Optional: Adjust the spring arm’s rotation to set camera angle (e.g., -80° Pitch).

Step 6: Mobile UI & Joystick Controls
Go to Project Settings → Maps & Modes:

Set the default GameMode to your BP_GameMode.

Set the Editor Startup Map to your main mobile level.

Search "Touch" in the Project Settings and:

Enable single-finger controls (“Always Show Touch Interface” or equivalent).

Ensure settings for joystick/touch input are ON (these enable mobile controls).

Customize the Touch Interface:

Create/copy a touch joystick from Unreal’s templates.

Assign this new joystick as the Default Touch Interface in Project Settings.

For a single joystick (no dual sticks), remove unnecessary elements and copy only what's needed.

Turn on “Prevent Recenter” for smoother thumbstick motion.

Step 7: Testing & Preview
Go to Editor Preferences:

Set “Play” settings to “New Editor Window (PIE)” for pop-out preview.

Use Mobile Preview (PIE) to see how your game will look on devices.

Add a Player Start actor to your level.

Adjust spring arm or camera as needed for better view.

Play in the editor and test all joystick/mobile controls.
