Easy Vehicle System

Complete driveable vehicle solution for Unreal Engine 5. Create fully functional vehicles in minutes - no coding required!

v1.0.0 UE 5.3 - 5.6+ 100% C++

📦 Installation

💡

Before you start: Make sure you have Unreal Engine 5.3 or newer installed. This plugin does NOT work with UE4.

Download & Extract the Plugin

After purchasing, download the EasyVehicleSystem_v1_0_0_UE5_6.zip file.

Extract the ZIP file. You should see a folder called EasyVehicleSystem.

⚠️

Important: Do NOT extract inside the ZIP! Right-click → Extract All, or use 7-Zip/WinRAR.

Copy to Your Project's Plugins Folder

Navigate to your Unreal Engine project folder. This is where your .uproject file is located.

If you DON'T have a Plugins folder:

Create a new folder called Plugins (capital P!)

Copy the entire EasyVehicleSystem folder into your Plugins folder.

Your folder structure should look like this:

📁 YourProject/ ├── 📁 Content/ ├── 📁 Config/ ├── 📁 Plugins/ ← Create this if it doesn't exist! │ └── 📁 EasyVehicleSystem/ ← Put the plugin HERE │ ├── 📁 Source/ │ ├── 📁 Resources/ │ ├── 📄 EasyVehicleSystem.uplugin │ └── 📄 ... └── 📄 YourProject.uproject

🚫

WRONG: Don't put it in Engine/Plugins or inside the Content folder!

Open Your Project in Unreal Engine

Double-click your .uproject file to open Unreal Engine.

If you see this popup:

"Missing modules - would you like to rebuild?"

Click YES! The plugin needs to compile for your project.

⏱️

First time? Compilation may take 1-5 minutes depending on your PC. Grab a coffee! ☕

Enable the Plugin (If Not Already Enabled)

In Unreal Engine:

Go to Edit → Plugins
In the search box, type Easy Vehicle
Make sure the checkbox is ✅ Enabled
If you had to enable it, click Restart Now

Plugins window with "Easy Vehicle System" enabled

Verify Installation ✅

Let's make sure everything works!

Test 1: In Content Browser, click Settings (gear icon) → Enable "Show Plugin Content". You should now see EasyVehicleSystem Content folder.

Test 2: Create any Actor Blueprint, click Add Component, and search for EVS. You should see:

EVS Audio Component
EVS Lighting Component
EVS Interaction Component
EVS Door Component
EVS Fuel Component
EVS HUD Component
EVS Wheel Component

🎉

If you see all components, installation is complete! Continue to create your first vehicle.

🚀 Creating Your First Vehicle

Let's create a working vehicle from scratch. This guide assumes you have NO vehicle mesh - we'll use UE5's default vehicle template!

🎯

Goal: In 10 minutes, you'll have a driveable car with engine sounds, lights, horn, and enter/exit functionality.

Create a New Blueprint

In Content Browser, right-click → Blueprint Class
In the popup, click "All Classes" at the bottom
Search for EVSVehicleBase
Select it and click Select
Name it BP_MyFirstVehicle

Pick Parent Class → All Classes → EVSVehicleBase

⚠️

Can't find EVSVehicleBase? The plugin isn't installed correctly. Go back to Installation step.

Open the Blueprint

Double-click on BP_MyFirstVehicle to open the Blueprint Editor.

You'll see the component hierarchy on the left:

BP_MyFirstVehicle (Self) ├── Mesh (Skeletal Mesh) ← Your car model goes here ├── VehicleMovement ← Chaos physics (auto-configured) ├── SpringArm ← Camera boom │ └── Camera ← The camera ├── InteriorCameraPoint ← First-person view position ├── AudioComponent ← All sounds ├── InteractionComponent ← Enter/exit detection └── LightingComponent ← All lights

Everything is already set up! You just need to add a car mesh.

Add a Vehicle Mesh

Option A: Use UE5's Built-in Vehicle (Easiest)

Enable the Vehicle Template plugin:
- Edit → Plugins → Search "Vehicle" → Enable "Vehicle Template"
- Restart editor
In your Blueprint, select the Mesh component
In Details panel, find Skeletal Mesh
Click the dropdown and search for SK_SportsCar or Vehicle
Select the mesh

Option B: Use Your Own Vehicle Mesh

Import your Skeletal Mesh (FBX) into the project
Make sure it has a Physics Asset
Make sure it has wheel bones named consistently (e.g., Wheel_FL, Wheel_FR, etc.)
Select the Mesh component → Set your Skeletal Mesh

💡

No mesh yet? The Unreal Marketplace has free vehicle meshes. Search for "vehicle skeleton" in the Fab marketplace.

Configure Wheel Setup

This is the most important step for the car to move properly!

Select the VehicleMovement component
In Details panel, find Wheel Setups
You should see 4 entries (FL, FR, RL, RR)
For each wheel, set:
- Wheel Class: Leave default or create custom
- Bone Name: The exact name of the wheel bone in your skeleton

Common Wheel Bone Names:

Position	Common Names
Front Left	`Wheel_FL`, `WheelFrontLeft`, `wheel_lf`
Front Right	`Wheel_FR`, `WheelFrontRight`, `wheel_rf`
Rear Left	`Wheel_RL`, `WheelRearLeft`, `wheel_lr`
Rear Right	`Wheel_RR`, `WheelRearRight`, `wheel_rr`

⚠️

Bone names must match EXACTLY! Open your Skeleton asset to see the real bone names. Case matters!

Place Vehicle in Level & Test!

Compile and Save your Blueprint (buttons at top)
Drag BP_MyFirstVehicle from Content Browser into your level
Make sure the vehicle is above the ground (not clipping through)
Add a Player Start nearby (so you can walk to the car)
Press Play!

Test your vehicle:

Walk to the car - you should see "Press [F] to Enter" prompt (or your character enters interaction range)
Press F to enter the vehicle
Press E to start the engine
Press W to accelerate
Press F again to exit

🎉

Congratulations! You have a working vehicle! Continue reading to add sounds, set up input properly, and customize everything.

🎮 Input Setup (Enhanced Input)

The Easy Vehicle System uses Unreal's Enhanced Input System. You need to create Input Actions and a Mapping Context for full control.

⚠️

Why isn't my vehicle responding to input? You probably haven't assigned Input Actions yet! Follow this section carefully.

Create Input Actions Folder

In Content Browser, create a new folder: Input
Inside Input, create another folder: VehicleActions

Your structure: Content/Input/VehicleActions/

Create All Input Actions

For each action below, right-click → Input → Input Action:

Name	Value Type	What It Does
`IA_Vehicle_Throttle`	Axis1D (Float)	Accelerate
`IA_Vehicle_Brake`	Axis1D (Float)	Brake/Reverse
`IA_Vehicle_Steering`	Axis1D (Float)	Turn left/right
`IA_Vehicle_Handbrake`	Digital (Bool)	Handbrake
`IA_Vehicle_Engine`	Digital (Bool)	Start/Stop engine
`IA_Vehicle_Horn`	Digital (Bool)	Honk horn
`IA_Vehicle_Lights`	Digital (Bool)	Toggle headlights
`IA_Vehicle_LeftIndicator`	Digital (Bool)	Left blinker
`IA_Vehicle_RightIndicator`	Digital (Bool)	Right blinker
`IA_Vehicle_Camera`	Digital (Bool)	Switch camera view
`IA_Vehicle_Exit`	Digital (Bool)	Exit vehicle
`IA_Vehicle_LookAround`	Axis2D (Vector2D)	Free look camera
`IA_Vehicle_Radio`	Digital (Bool)	Toggle radio
`IA_Vehicle_NextStation`	Digital (Bool)	Next radio station
`IA_Vehicle_PrevStation`	Digital (Bool)	Previous station
`IA_Vehicle_Wipers`	Digital (Bool)	Toggle wipers

💡

How to set Value Type: Double-click the Input Action → In Details panel, set "Value Type" to the type shown above.

Create Input Mapping Context

Right-click in your Input folder → Input → Input Mapping Context
Name it IMC_Vehicle
Double-click to open it
Click the + button to add mappings

Add these mappings:

Input Action	Key	Modifiers (if needed)
IA_Vehicle_Throttle	`W`	-
IA_Vehicle_Brake	`S`	-
IA_Vehicle_Steering	`A`	Negate (for left)
IA_Vehicle_Steering	`D`	- (for right)
IA_Vehicle_Handbrake	`Space`	-
IA_Vehicle_Engine	`E`	-
IA_Vehicle_Horn	`H`	-
IA_Vehicle_Lights	`L`	-
IA_Vehicle_LeftIndicator	`Q`	-
IA_Vehicle_RightIndicator	`R`	-
IA_Vehicle_Camera	`C`	-
IA_Vehicle_Exit	`F`	-
IA_Vehicle_LookAround	`Mouse XY`	-
IA_Vehicle_Radio	`M`	-
IA_Vehicle_NextStation	`.`	-
IA_Vehicle_PrevStation	`,`	-

Assign to Your Vehicle Blueprint

Open your vehicle Blueprint (BP_MyFirstVehicle)
Select the root component (Self)
In Details panel, scroll down to "EVS Input" section
Assign each Input Action to its corresponding slot:

EVS Input Section: ├── Vehicle Mapping Context → IMC_Vehicle ├── Throttle Action → IA_Vehicle_Throttle ├── Brake Action → IA_Vehicle_Brake ├── Steering Action → IA_Vehicle_Steering ├── Handbrake Action → IA_Vehicle_Handbrake ├── Toggle Engine Action → IA_Vehicle_Engine ├── Horn Action → IA_Vehicle_Horn ├── Toggle Lights Action → IA_Vehicle_Lights ├── Left Indicator Action → IA_Vehicle_LeftIndicator ├── Right Indicator Action → IA_Vehicle_RightIndicator ├── Toggle Camera Action → IA_Vehicle_Camera ├── Exit Vehicle Action → IA_Vehicle_Exit ├── Look Around Action → IA_Vehicle_LookAround ├── Toggle Radio Action → IA_Vehicle_Radio ├── Next Station Action → IA_Vehicle_NextStation └── Prev Station Action → IA_Vehicle_PrevStation

✅

Done! Compile, save, and test. All inputs should now work!

🔊 Audio System

The EVSAudioComponent handles all vehicle sounds. It supports engine sounds with RPM-based pitch, horn, doors, indicators, wipers, and even a radio system!

Adding Sounds to Your Vehicle

Open your vehicle Blueprint
Select AudioComponent in the Components panel
In Details panel, find the "EVS Audio" categories
Assign your sound assets to each slot

Available Sound Slots

Category	Sound Slot	Description	Type
Engine	Engine Start Sound	Played when starting engine	One-shot
	Engine Stop Sound	Played when stopping engine	One-shot
	Engine Loop Sound	Continuous engine sound (pitch changes with RPM)	Looping
Horn	Horn Sound	Played while holding horn button	Looping
Doors	Door Open Sound	When entering/exiting	One-shot
Doors	Door Close Sound	After entering/exiting	One-shot
Lights	Light Switch Sound	Click when toggling lights	One-shot
Lights	Indicator Tick Sound	Blinker tick sound	One-shot (repeats)
Wipers	Wipers Loop Sound	While wipers active	Looping
Radio	Radio Stations (Array)	Music tracks	Looping
	Radio Static Sound	When changing stations	One-shot
	Radio Toggle Sound	On/off click	One-shot
Misc	Handbrake Sound	Handbrake engage sound	One-shot
Misc	Seatbelt Sound	Buckle click	One-shot

Engine Sound Settings

The engine loop sound's pitch changes based on RPM. Configure these in AudioComponent:

Setting	Default	Description
Engine Min Pitch	0.8	Pitch at idle (0 RPM)
Engine Max Pitch	2.0	Pitch at max RPM
Indicator Tick Interval	0.5	Seconds between blinker ticks
Radio Volume	0.7	Radio music volume (0-1)

💡

Pro Tip: For realistic engine sounds, use a Sound Cue with multiple layers (idle, low RPM, high RPM) and crossfade between them. The EVS system will still control the pitch!

Radio System

Add music tracks to the Radio Stations array. Players can cycle through them with Next/Previous station keys.

Select AudioComponent
Find Radio Stations array
Click + to add entries
Assign Sound Wave or Sound Cue assets

💡 Lighting System

The EVSLightingComponent creates dynamic lights for your vehicle: headlights, tail lights, brake lights, reverse lights, and indicators.

How It Works

Lights are created automatically at runtime based on position offsets you configure. No need to manually add light components!

Configuring Light Positions

Open your vehicle Blueprint
Select LightingComponent
In Details, find "EVS Lighting | Positions"
Adjust the offset vectors to match your car mesh

Position Offsets

Light	Default Offset (X, Y, Z)	Tips
Left Headlight	(220, -70, 50)	X = Forward, Y = Left
Right Headlight	(220, 70, 50)	X = Forward, Y = Right
Left Tail Light	(-220, -70, 60)	Negative X = Rear
Right Tail Light	(-220, 70, 60)
Left Indicator Front	(230, -80, 45)	Usually outer edge
Right Indicator Front	(230, 80, 45)
Left Indicator Rear	(-230, -80, 55)
Right Indicator Rear	(-230, 80, 55)

Light Settings

Setting	Default	Description
Headlight Color	Warm White	Color of headlights
Headlight Intensity	20000	Brightness (candelas)
Headlight Range	2000	Attenuation radius
Tail Light Color	Red
Tail Light Intensity	500	Normal brightness
Brake Light Intensity	3000	When braking
Indicator Color	Orange
Indicator Blink Rate	0.5	Seconds per blink

💡

Debugging lights: In Play mode, toggle Show → Lights in the viewport to see light radii. Adjust positions until they align with your mesh.

🚪 Enter/Exit System

The EVSInteractionComponent handles proximity detection and smooth enter/exit transitions.

How It Works

Player walks near the vehicle (within Interaction Radius)
Component detects the player and fires OnCharacterEnteredRange
Player presses the Exit/Enter key (default: F)
Vehicle's EnterVehicle() function is called
Player character is hidden and Player Controller possesses the vehicle

Settings

Setting	Default	Description
Interaction Radius	200	How close player must be (cm)
Driver Door Offset	(0, -120, 0)	Where the "entry point" is
Exit Offset	(0, -180, 50)	Where player appears on exit
Show Interaction Prompt	true	Enable/disable UI prompt
Interaction Prompt Text	"Press [F] to Enter"	Text to show

Safety Settings (on Vehicle Base)

Setting	Default	Description
Allow Exit While Moving	false	Can player exit at speed?
Safe Exit Speed (km/h)	5	Max speed for safe exit

⚠️

Player not entering? Make sure your player character has collision and the interaction radius is large enough. Try increasing it to 300-400 for testing.

⛽ Fuel System (Optional)

The EVSFuelComponent adds realistic fuel consumption. It's optional - if you don't want fuel mechanics, just disable it!

Enable/Disable Fuel System

Open your vehicle Blueprint
Click Add Component → EVS Fuel Component
Or if already present, set Fuel System Enabled = false to disable

Fuel Settings

Setting	Default	Description
Fuel System Enabled	true	Master on/off
Max Fuel	60 L	Tank capacity
Starting Fuel	60 L	Fuel at spawn
Idle Consumption	1 L/hour	Fuel use when idling
Max Consumption	15 L/hour	Fuel use at full throttle
Low Fuel Threshold	15%	When to trigger warning
Stop Engine When Empty	true	Auto-stop on empty tank

Blueprint Events

OnLowFuel - Fires when fuel drops below threshold
OnFuelEmpty - Fires when tank is empty
OnRefueled(float NewAmount) - Fires after adding fuel

Refueling

// Blueprint or C++:
FuelComponent->AddFuel(30.0f);  // Add 30 liters
FuelComponent->FillTank();        // Fill to max
FuelComponent->SetFuel(50.0f);   // Set exact amount

🔧 Troubleshooting

❌ Vehicle doesn't move at all

Check these in order:

Is the engine ON? Press E to start it
Is the handbrake OFF? Press Space to toggle
Are Input Actions assigned in the Blueprint?
Is the Input Mapping Context assigned?
Are wheel bone names correct? (Check Skeleton)
Does the mesh have a Physics Asset assigned?

❌ Vehicle flips or behaves strangely

Physics issues:

Check that wheel bone names match EXACTLY (case-sensitive!)
Make sure Physics Asset is properly configured
Check that the center of mass is correct (should be low and centered)
Try increasing wheel mass or adjusting suspension

❌ Can't enter the vehicle

Make sure InteractionComponent is present
Increase Interaction Radius (try 400)
Check that your player character has collision enabled
Make sure IA_Vehicle_Exit is set up and bound to F

❌ No sounds playing

Did you assign sound assets to AudioComponent?
Are the sounds imported correctly? (WAV recommended)
Is the game volume up?
Check that AudioComponent is not disabled

❌ Lights not visible

Are headlights turned ON? Press L
Check light position offsets - they might be inside the mesh
Increase Headlight Intensity (try 30000+)
Make sure it's dark enough in your level to see them

❌ Compilation errors

Make sure you're using UE 5.3 or newer
Delete Binaries, Intermediate, and Saved folders
Right-click .uproject → Generate Visual Studio files
Rebuild the project

❌ Plugin not showing up

Check folder structure: Plugins/EasyVehicleSystem/EasyVehicleSystem.uplugin
Make sure it's not Plugins/EasyVehicleSystem/EasyVehicleSystem/... (double folder)
Restart the editor
Check Edit → Plugins → Search for "Easy Vehicle"

❓ FAQ

Can I use this for multiplayer?

The current version is designed for single-player. Multiplayer replication is planned for v1.2. For now, you would need to add replication logic yourself.

Does it work with AI?

The plugin is designed for player-controlled vehicles. AI vehicle controller is planned for a future update. You can create your own AI controller that calls the movement functions.

Can I use my own vehicle mesh?

Yes! Any Skeletal Mesh with proper wheel bones will work. Make sure you have:

Physics Asset
Wheel bones (4 minimum)
Proper bone hierarchy

Can I have multiple vehicles in one level?

Yes! Each vehicle is independent. The player can exit one and enter another.

How do I make a faster car?

In your Blueprint, change:

Max Speed (km/h) - e.g., 280 for a sports car
VehicleMovement → Engine Setup → Max RPM
VehicleMovement → Transmission → Gear Ratios

How do I disable fuel consumption?

Either:

Don't add EVSFuelComponent, or
Set Fuel System Enabled = false

Can I modify the source code?

Yes! Full C++ source is included. You can modify anything for your project. However, you cannot redistribute modified versions.
