Camera switching 1st to 3rd person – step-by-step
Here’s the **skinny step-by-step (SBS)** version for camera switching in Unreal Engine 5 — between **first** and **third person** views:
—
### 1️⃣ Function:
**Toggle between first- and third-person cameras** using one key press.
—
### 2️⃣ Code/Blueprint flow:
**A. Setup Two Cameras**
– In your **Character Blueprint (e.g., BP_ThirdPersonCharacter)**:
1. Add **Camera1** → attach to head (for first-person view).
2. Add **Camera2** → attach to spring arm (for third-person view).
3. Set **Camera2** as the **default active camera**.
**B. Input Mapping Context (Enhanced Input)**
– Open **IMC_Default** (or create your own).
– Add a new **Action** → `IA_ToggleView`.
– Bind it to a key, e.g. **V**.
**C. Character Blueprint Logic**
– In Event Graph:
1. Create a **boolean variable** → `bIsFirstPerson`.
2. Add **Input Action → IA_ToggleView** event.
3. Use **FlipFlop** or **Branch**:
“`
if bIsFirstPerson:
Set View Target with Blend → Camera2
Set bIsFirstPerson = false
else:
Set View Target with Blend → Camera1
Set bIsFirstPerson = true
“`
*(Optional)* use **SetActive** on the cameras instead of ViewTarget if both are on the same pawn.
**D. (Optional) Smooth Transition**
– Use **SetViewTargetWithBlend** node → `Blend Time = 0.5` for smoother switch.
—
### 3️⃣ Flow Summary:
**Key Press (V)** → triggers Input Action → toggles `bIsFirstPerson` → switches between two cameras (head vs. spring arm).
—
Would you like it to auto-switch to **first-person when near an interactable (like chest or kiosk)** next?
Now the car is setup with both cameras, and the character is – now I need to get into the car. IA (when close to the door handle 1m) V will switch from either inside car or player. So create new IA call OpenCarDoor , find animation for reaching (right?) and then switch controllers
Exactly. Here’s the **skinny SBS version** for **entering/exiting a car** when near it using `IA_OpenCarDoor`:
—
### 1️⃣ Function
When the player is within ~1 m of the car door and presses **V**, play a “reach/open” animation → switch control from **Character → Car** (and reverse).
—
### 2️⃣ Implementation
**A. Input Setup**
– In your **Input Mapping Context**:
– Add new action: `IA_OpenCarDoor`.
– Bind it to **V** (same as before).
**B. Proximity Check (Trigger Zone)**
– On the **Car Blueprint**:
1. Add a **Box Collision** → name it `DoorTrigger`.
2. Set its size ≈ 100 cm around the driver door.
3. On **BeginOverlap** → store reference to overlapping player (`PlayerRef`).
4. On **EndOverlap** → clear that reference.
**C. Animation (optional but better)**
– On press of `IA_OpenCarDoor`, if `PlayerRef` exists:
1. Play **“Reach/OpenDoor” montage** (right arm).
2. Use **Delay(AnimLength)** → then trigger control switch.
**D. Possession Switch**
In the **Character BP** or **Player Controller**:
“`
if CloseToCar (DoorTrigger overlap == true):
UnPossess current pawn
Possess Car (car actor reference)
else:
UnPossess Car
Possess Character
“`
Use **SetViewTargetWithBlend** for smooth camera shift between character and car cameras.
—
### 3️⃣ Flow Summary
**Player near car → Press V → Play reach anim → UnPossess Character → Possess Car → switch camera**
(Repeat to exit back).

Would you like the **Blueprint node layout** for this next (visual flow of the logic in the Character BP)?
Have the IA for character OpenDoor and ExitCar – Added collision box to car Check any details?
Perfect — you’re 80% there. Here’s the **checklist + fine-details** so it all works cleanly:
—
### ✅ 1️⃣ Car Blueprint Setup
**Components:**
– `DoorTrigger` (Box Collision) → around driver door.
– `CarMesh`, `CarCamera_Inside`, `CarCamera_Outside`, etc.
**DoorTrigger Details:**
– **Collision Preset:** OverlapAllDynamic (or custom).
– **Generate Overlap Events:** ✔️
– On `BeginOverlap`:
– Check `OtherActor` → `Cast to BP_Character`.
– `Set` → `PlayerRef` variable.
– On `EndOverlap`:
– `Clear` `PlayerRef`.
—
### ✅ 2️⃣ Character Blueprint
**Variables:**
– `bNearCar` (bool)
– `CurrentCarRef` (Car BP reference)
**Logic (OnOverlap from Car)**
– When overlap → set `bNearCar = true`, `CurrentCarRef = overlapped car`.
– When end overlap → reset both.
—
### ✅ 3️⃣ Input Actions
**IA_OpenDoor** (V):
“`
if bNearCar == true:
Play Montage (Open Door reach)
Delay (anim length)
UnPossess self
Possess CurrentCarRef
SetViewTargetWithBlend (to car camera)
“`
**IA_ExitCar** (also V or another key):
“`
UnPossess car
Possess PlayerRef (original character)
SetViewTargetWithBlend (to character camera)
“`
*(Use boolean like `bIsInCar` to toggle which branch fires.)*
—
### ✅ 4️⃣ Player Controller
Keep the **Player Controller** persistent — only possession changes.
– Don’t destroy or respawn the character; just possess/unpossess.
– On car possession, disable player mesh visibility if it clips (optional).
—
### ✅ 5️⃣ Animations (optional polish)
– **Open Door Reach:** any “open car door” or “reach handle” animation (right hand).
– **Enter Animation:** simple sit/mount animation can blend in.
– Sync timing with the camera switch.
—
### ⚙️ Flow Summary
1. Player overlaps `DoorTrigger` → `bNearCar` = true
2. Press **V** → play “OpenDoor” → possess car + blend camera
3. Press **V** again → `ExitCar` → possess player back
—
Would you like me to sketch the **exact Blueprint node flow** for that OpenDoor event (entry/exit toggle)?
My box componenet is call DrverDorr I dragged the pin into the blueprint. But should I be working with the player?
Yes — correct instinct.
You always handle **the input logic (IA_OpenDoor, IA_ExitCar)** in the **player’s blueprint** (Character or PlayerController) — not inside the car.
Here’s the clean structure 👇
—
### 🔧 Blueprint Division
**🚗 Car Blueprint (BP_Car)**
– Only **detects overlap**.
– Has `DriverDoor` (your Box Component).
– On **BeginOverlap** → Cast to your **Character BP** and call a **Custom Event** on the character (e.g., `EnteredCarZone(Self)`).
– On **EndOverlap** → call `LeftCarZone()`.
That’s it — no input logic inside the car.
—
**🧍 Character Blueprint (BP_Player)**
– Owns input (IA_OpenDoor / IA_ExitCar).
– Has vars:
– `bNearCar` (bool)
– `CurrentCarRef` (BP_Car ref)
– `bIsInCar` (bool)
**Logic:**
“`
Event EnteredCarZone(CarRef)
→ bNearCar = true
→ CurrentCarRef = CarRef
Event LeftCarZone()
→ bNearCar = false
→ CurrentCarRef = None
IA_OpenDoor (V)
→ Branch bIsInCar
→ if false and bNearCar:
Play Reach Anim
Delay(anim time)
UnPossess
Possess CurrentCarRef
Set bIsInCar = true
→ else:
UnPossess
Possess Self
Set bIsInCar = false
“`
—
**🧭 Why do it this way?**
– Player always owns inputs.
– Cars only detect collisions.
– Keeps modular control (any car can be entered).
—
So yes — drag from **DriverDoor → OnComponentBeginOverlap** inside the **car**, but just use it to **notify the player**, not to switch control directly.
SO next. lets notify player
Exactly — now you wire the **notification from the car → player** cleanly.
Here’s the skinny SBS version 👇
—
### 1️⃣ Function
When the player overlaps `DriverDoor`, the **Car BP** notifies the **Player BP** that entry is possible.
—
### 2️⃣ Blueprint Flow
**In BP_Car**
1. Select `DriverDoor` → scroll to **Events** → click **+ OnComponentBeginOverlap**.
2. Drag from `OtherActor` → **Cast To BP_Player** (your character class).
3. From the **As BP_Player** pin → call a **Custom Event** on the player:
“`
EnteredCarZone(Self)
“`
(pass `Self` = car reference).
4. Do the same for **OnComponentEndOverlap** → call
“`
LeftCarZone()
“`
—
**In BP_Player**
1. Add those custom events:
– `EnteredCarZone(CarRef)`
“`
Set bNearCar = true
Set CurrentCarRef = CarRef
“`
– `LeftCarZone()`
“`
Set bNearCar = false
Clear CurrentCarRef
“`
2. Confirm these variables exist:
– `bNearCar` (bool)
– `CurrentCarRef` (object ref to BP_Car)
—
### 3️⃣ Flow Summary
Player walks near door → overlap fires in car → car calls `EnteredCarZone` on player → sets `bNearCar = true` → player ready to press **V** to enter.
—
Ready for me to show the **OpenDoor (V) event flow** next — where you use `bNearCar` and `CurrentCarRef` to actually possess the car?
I don’t unhderstande :Blueprint Flow
In BP_Car
Select DriverDoor → scroll to Events → click + OnComponentBeginOverlap.
Drag from OtherActor → Cast To BP_Player (your character class).
From the As BP_Player pin → call a Custom Event on the player:
Good — let’s break that into **micro steps** you can literally click through in the editor:
—
### 🎯 Goal
When the player enters the **DriverDoor** box on the **car**, the car will *tell* the player “Hey, I’m nearby.”
—
### 🧱 Step-by-Step in **BP_Car**
1. **Open your car blueprint** (`BP_Car`).
2. In the **Components panel**, click on your **DriverDoor** box.
3. With it selected, look at the **Details** panel.
– Scroll down to the **Events** section (bottom).
– Find **On Component Begin Overlap**.
– Click the **+** button next to it.
→ This adds a new **Event Node** in the Event Graph.
4. You’ll see a node that says
“`
Event DriverDoor → OnComponentBeginOverlap (DriverDoor)
“`
It has an **Other Actor** output pin.
5. Drag a wire out of **Other Actor** → search **Cast To BP_Player**
(this checks if what overlapped is your player character).
6. From the **As BP_Player** output pin (the blue one):
drag a wire → type **EnteredCarZone**
(if you don’t see it yet, we’ll make it next in the Player BP).
7. On that new **EnteredCarZone** node, it will ask for an input —
drag the white **Self** pin from the left side of your BP_Car graph into it.
That sends a reference to *this* car to the player.
—
### 🧍 In **BP_Player**
1. Open your player blueprint.
2. Right-click anywhere in the graph → choose **Add Custom Event**.
3. Name it **EnteredCarZone**.
4. Click the node → in the Details panel → add a **new input**:
– Type: `BP_Car` (object reference)
– Name: `CarRef`
5. Off that event node, add:
“`
Set bNearCar = true
Set CurrentCarRef = CarRef
“`
6. Do the same for **EndOverlap** back in BP_Car**
– Add “OnComponentEndOverlap” → Cast To BP_Player → call `LeftCarZone()`
– Create matching event in BP_Player to clear the vars.
—
Once this link is in place, the car can “ping” the player every time you enter or leave the door zone.
Then your player’s **IA_OpenDoor (V)** logic will know when it’s allowed to take control.
