List files and extensions

what is the command to list a dir’s files and extension only

To list **only the filenames and their extensions** in a directory (no full paths, no file sizes, no subdirs), the exact command depends on the shell you’re using. Here’s how to do it in various environments:

### 🐧 **Linux/macOS (bash/zsh):**
“`bash
ls -p | grep -v /
“`

– `ls -p`: lists files and directories, appending `/` to directories
– `grep -v /`: removes directories from the output, leaving only files (with extensions)

**To show only the extensions:**
“`bash
ls -p | grep -v / | sed ‘s/.*.//’
“`

### 🪟 **Windows Command Prompt (CMD):**
“`cmd
dir /b /a:-d
“`

– `/b`: bare format (just names)
– `/a:-d`: exclude directories

**To show only extensions (sorta hacky):**
“`cmd
for %f in (*.*) do @echo %~xf
“`

### 🐍 **Python (cross-platform one-liner):**
“`bash
python -c “import os; [print(f) for f in os.listdir(‘.’) if os.path.isfile(f)]”
“`

Let me know if you want to recurse subdirectories or filter specific extensions (like only `.jpg` or `.cpp`).
Do you think it is possible to take a streaming game, elite dangerous and overlay an emulated lidar scanner?
Yes—**it is technically possible**, but you’re looking at a bit of a Frankenstein setup. Let’s break it down.

### 🧠 TL;DR:
You can overlay a simulated LiDAR scanner onto *Elite Dangerous* if:
– You’re capturing the game feed (via OBS, Virtual Desktop, etc.)
– You can hook into positional data (VR headset tracking or joystick movement)
– You render a custom overlay using that data, ideally in a transparent window or via in-VR overlay injection.

### 🔧 Your Setup Checklist:

1. **Elite Dangerous is streaming (flat or VR)**
→ If it’s via *Virtual Desktop* or *SteamVR*, you can tap into the stream or the render pipeline.

2. **Create the LiDAR emulator**
– Simulate “pings” from the player’s view
– Could use fake radial distance logic or approximate depth
– Render results as dots, wireframes, or sonar-style sweep

3. **Overlay System**
– Use something like:
– [OpenVR Overlay](https://github.com/SDraw/openvr-overlay-tutorial) for native VR injection
– OBS overlay for flat streams (transparent window always-on-top)
– [SteamVR’s OpenXR Layer](https://github.com/ValveSoftware/openxr-overlay-layer) for modern hook-ins

4. **Optional: Use AI for scene depth**
You could get fancy and use something like:
– Monocular depth estimation from video stream (with AI)
– [MiDaS](https://github.com/isl-org/MiDaS) or similar to “fake” LiDAR returns
– Might add latency, but feels *futuristically hacky* and cool

### 🧪 Concept Prototype:
1. **Capture your headset’s direction vector**
– via SteamVR API or OpenXR
2. **Send simulated “pings” into the center of your screen**
– Overlay radial lines + delay returns
3. **Render those pings visually**
– In a circular sweep (LiDAR style) or as dot clouds

### 🚨 Caveats:

– No access to *Elite Dangerous’s* actual 3D data = you’re faking the depth
– Latency or performance hit depending on how you overlay
– You *cannot* modify Elite Dangerous itself (closed engine), only watch/overlay

### 🔥 Wild idea:

Use an AI model that takes a camera feed from ED and tries to guess depth (pseudo-LiDAR), while your overlay “pings” respond based on brightness/depth of regions. It’s not real LiDAR, but it *feels* like scanning a world.

Want a blueprint for the overlay code or a mock-up?
Ok. I have a BP to spin an object in the graph there is Togglespin (CE) //flipflop A out to SET, B out to antoehr set of a created varialbe called shouldspin bool. Off the event tick is connect to Add Actor Local Rotation. I have WBP_SpinGo as a button yet unwired. Help me solve this
Nice—you’re halfway to a clean little spin-toggle setup. Let’s walk it in step-by-step, wiring up your `WBP_SpinGo` button to toggle your `shouldSpin` bool and use it in the Tick rotation.

### 🛠️ Goal:
– Click a UI button (`WBP_SpinGo`)
– Toggles spinning an object
– `Event Tick` rotates object only if `shouldSpin == true`

### ✅ Current Setup Recap:
1. **`ToggleSpin (Custom Event)`**
– FlipFlop → A → Set `shouldSpin = true`
– FlipFlop → B → Set `shouldSpin = false`

2. **`Event Tick`**
– Branch (Condition: `shouldSpin`)
– → AddActorLocalRotation

3. **`WBP_SpinGo` (UI button)**: Exists, but not connected to logic yet

### ✅ Fix Plan:

#### 1. **Expose the Actor to Blueprint (if needed)**
In the widget, you need to reference the spinning actor.

– In your spinning actor, **make it implement a function like `ToggleSpin()`**
– Or, expose a `shouldSpin` variable you can flip from the widget (cleaner with a function though)

#### 2. **In WBP_SpinGo (Widget Blueprint):**
On your Button’s `OnClicked` event:

“`unreal
Get Owning Player Pawn → Cast to [YourActorClass] → Call `ToggleSpin()`
“`

– Replace `[YourActorClass]` with the actual spinning actor’s class (or interface if you want it cleaner long-term)

#### 3. **Quick sanity check:**
– Is your widget added to the viewport?
– Does the button actually respond (test with a Print String)?
– Does the actor exist in the level and respond to the function call?

### 🧠 Summary Flow:

– Button Clicked → Calls `ToggleSpin()` on Actor
– `ToggleSpin()` uses FlipFlop → Sets `shouldSpin`
– `Event Tick` → Branch on `shouldSpin` → Rotate

### ⚡ Bonus: Clean It Up (Optional)

– Instead of FlipFlop, just do:
“`unreal
shouldSpin = !shouldSpin
“`
Using `NOT` node + Set

– That removes a bunch of visual node clutter and makes your intent clear.

Need a screenshot-style layout or want me to generate a Blueprint node diagram of the above?
Get Owning Player Pawn → Cast to [YourActorClass] → Call `ToggleSpin()` **Important:** Custom Events don’t show up in other Blueprints unless they are **`public`** (or better yet, replaced by a proper function).

#### 🔹 2. **You’re casting to the wrong actor**
– `Get Owning Player Pawn` gives you the player character.
– If your spinning object isn’t the Pawn (and likely isn’t), your cast fails or shows nothing.

> ✅ Instead: Add a **variable** in the widget:
> `TargetActor (type: your spinner actor class, Exposed on Spawn + Instance Editable)`

Then, when you add the widget in your level (or from your controller), do:

“`unreal
Create Widget → Set TargetActor → Add to Viewport
“`

Then in `WBP_SpinGo`, do:

“`unreal
On Button Clicked → Call ToggleSpin() on TargetActor
“`

#### 🔹 3. **`ToggleSpin` was added after you opened the widget**
Unreal is sometimes a forgetful squirrel. Try **closing and reopening the widget BP** or **compiling both BPs**.

### 🧪 Super Quick Fix:
If you just want a fast proof-of-life:

1. In your spinning actor:
“`unreal
Create a new `Function` called ToggleSpin
→ NOT node from `shouldSpin` → Set `shouldSpin`
“`

2. In the widget:
– Create `TargetActor` variable (type = your spinner actor)
– On Button Clicked → Call `ToggleSpin()` on `TargetActor`

3. When adding the widget (in your controller or level blueprint):
“`unreal
Create Widget (WBP_SpinGo)
→ Set TargetActor to the spinning actor in the level
→ Add to Viewport
“`

Want me to give you a minimal Blueprint diagram to copy?
Ok. Have the widget and when I click it it spins or stops. Great. Now. I do not want a widget I want the player to step on a pade and have it activate the spinning
Hell yes, welcome to trigger pad territory. Let’s yeet that widget and set up a **trigger volume or pad** that toggles spin when the player walks onto it.

### 🎯 Goal:
When the player steps on a pad → the object starts/stops spinning.

### 🛠️ Step-by-Step:

#### 1. **Create the Trigger Pad**
– Add an **Actor Blueprint** (e.g., `BP_SpinPad`)
– Add a `Box Collision` or `Sphere Collision` component (this is your pad)

#### 2. **Set Up Overlap Logic**
Inside `BP_SpinPad`:

“`unreal
Event BeginOverlap (Box)
→ Cast to [YourPlayerCharacter] // or check HasTag(“Player”)
→ Call `ToggleSpin()` on the spinning actor
“`

Optional:
– Use a `bool` to prevent spam (like only toggle on first entry)
– Or use `Event EndOverlap` to reverse it

#### 3. **Get Reference to the Spinner**
Several options:

– **Option A: Expose variable in the pad:**
– In `BP_SpinPad`, add:
– `TargetSpinner` variable (type = your spinning actor)
– Make it `Instance Editable` + `Expose on Spawn`
– Set it in the Level manually or when spawned

– **Option B: Use `Get All Actors Of Class`**
“`unreal
Get All Actors of Class → Get(0) → Call ToggleSpin
“`
(lazy but works for testing)

### 🧠 Event Flow Recap:
1. Player overlaps collision box
2. Pad Blueprint gets called
3. Calls `ToggleSpin()` on spinning actor
4. `ToggleSpin` flips the `shouldSpin` bool
5. Tick keeps rotating if true

### 🧪 Optional Bonus:
– Add particle effects / lights to the pad when active
– Add a “one-time trigger” bool
– Make the spinner pad itself spin once it’s triggered, for max irony

Want a visual Blueprint layout to plug in?
The type of Object is undetermined. Connect something to Cast To BP_StationSpinner to imply a specific type.
The current value of the ‘ Object ‘ pin is invalid: Unsupported type Object Wildcard on pin Object
Ah yes, the classic **”Object is a wildcard”** error — Unreal’s way of saying, *”Yo, I have no idea what you’re trying to cast here.”*

### 🧠 Translation:
The **`Object` pin** on your `Cast To BP_StationSpinner` node needs a specific **object reference** — but you’re giving it nothing (or something Unreal doesn’t understand).

### 🔧 Fix It Like This:

#### 🛠️ If you’re using **Get All Actors of Class**:
1. Add a `Get All Actors of Class` node.
2. Set the class to `BP_StationSpinner`.
3. From the `Out Actors` pin, drag out and do `Get (0)` — or a loop if you want multiple.
4. Plug the result into the `Object` pin of the `Cast To BP_StationSpinner` node.

**Or** — just skip the cast:
– The `Get (0)` node already returns a typed object if you set the class properly.
– So just drag from `Get (0)` → call `ToggleSpin()` directly (no cast needed).

#### 🛠️ If you’re using a **trigger pad variable** instead:
1. In your trigger pad Blueprint (`BP_SpinPad`):
– Add a variable: `TargetSpinner` (type: `BP_StationSpinner`, set to `Editable` and `Expose on Spawn`)
2. In the level editor, select your placed pad → in the **Details panel**, assign the spinner manually.
3. Now, you can **skip casting completely** — just:
“`unreal
TargetSpinner → Call ToggleSpin()
“`

### 🚫 What *not* to do:
– Don’t leave the Object pin empty and hope it works.
– Don’t feed it a component (like `Box Collision`) and expect it to be the spinner.

### ✅ Final Answer (Cleanest Flow):
In `BP_SpinPad`:

“`unreal
On Component Begin Overlap
→ Cast Other Actor to BP_ThirdPersonCharacter (or whatever your player is)
→ Valid? Then:
→ TargetSpinner → Call ToggleSpin()
“`

Let me know if you want to auto-find the spinner instead of assigning it manually.
Doesn’t work, but first lets remove the dont push wideget. Is it as simple aas removing the reference in the level bp?
Yep—removing the widget is **that simple**. If you’re no longer using the “Don’t Push” widget and want it gone, just follow these quick steps:

### 🧼 Remove the Widget (Simple Way):

#### 📍 If it was added in the **Level Blueprint**:
1. Open **Level Blueprint**
2. Look for the node chain that includes:
“`
Create Widget (WBP_SpinGo)
→ Add to Viewport
“`
3. **Delete those nodes** (or just disconnect them if you’re debugging)
4. Compile & Save

**Result:** Widget will no longer show up when you play.

#### 🧹 Extra Clean-up (Optional):
– In `WBP_SpinGo`, right-click it in the Content Browser → **Asset Actions → Delete** if you’re done with it.
– Or disable it with logic instead of deleting if you’re unsure.

### ✅ Confirm It’s Gone:
Hit *Play*. If that “Don’t Push” button doesn’t appear anymore, you’re good.
Next: let’s fix the trigger not calling `ToggleSpin()`. Want to step through that too?
Now lets get back to the spinpad.
Alright, pad time. Let’s laser-focus and get this `SpinPad` working like a sci-fi floor switch.

### 🎯 Objective:
When the **player** steps on the pad (`BP_SpinPad`), it toggles spinning on a specific actor (`BP_StationSpinner`).

## 🛠 Step-by-Step Setup:

### 🔹 1. **In `BP_StationSpinner`**
Make sure this exists:
“`unreal
Custom Event: ToggleSpin
→ NOT node on shouldSpin → Set shouldSpin
“`

✅ That flips the bool each time it’s called.

### 🔹 2. **In `BP_SpinPad`**
#### Add Components:
– `Box Collision` (or `TriggerVolume`)
– Optionally a static mesh so it looks like a pad

#### Add a Variable:
– Name: `TargetSpinner`
– Type: `BP_StationSpinner` (Object Reference)
– ✅ Check `Instance Editable` and `Expose on Spawn`

#### Add Overlap Logic:
“`unreal
OnComponentBeginOverlap (Box)
→ Cast Other Actor to YourPlayerCharacter (like BP_ThirdPersonCharacter)
→ IsValid(TargetSpinner)?
→ Call ToggleSpin() on TargetSpinner
“`

✔ This ensures it only fires when the player steps on it.

### 🔹 3. **In the Level**
1. Place a `BP_SpinPad` in the world
2. Select it in the level
3. In **Details panel**, look for `TargetSpinner` variable
4. Assign it to the `BP_StationSpinner` already in the scene

## ✅ Done! Result:
– Player walks onto pad
– Pad calls `ToggleSpin()` on the spinner
– Spinner starts or stops spinning

### 🔍 Debug Tips:
– Add a `Print String` before calling `ToggleSpin()` to confirm the pad is firing
– Confirm the `TargetSpinner` is *not empty* in the level
– If unsure which actor is triggering, print `Other Actor`’s name in overlap

Want a quick BP layout screenshot or node list for the `SpinPad` logic?
We have action! Now lets find another thing to do.
Boom. You stepped on a pad, made the world spin — you are now 87% of the way to becoming a Bond villain.

Let’s cook up your **next interactive thing**. Here are a few spicy options depending on how weird or ambitious you’re feeling:

### 🌀 INTERACTIVE IDEAS (Pick your flavor):

#### 🔸 1. **Proximity-triggered Hologram**
Walk near a console → a hologram activates → maybe with voice lines or visual data (using Niagara + decal projection)

#### 🔸 2. **Diggable Terrain Patch**
Let the player dig or deform a small section of terrain (pair this with your Nanite+mud dreams)

#### 🔸 3. **Rotating Puzzle Ring**
Like a sci-fi Stargate ring — step on pads to rotate segments. Match symbols to open a door.

#### 🔸 4. **Cymatic Sound Pool**
Step into a pool → surface animates with ripples or cymatic patterns based on tone or player action.

#### 🔸 5. **Ferrofluid Blob Interaction**
Player waves hand near a tank — ferrofluid spikes toward them based on distance or gesture

#### 🔸 6. **Scanning Beam (fake LiDAR)**
A sweeping beam rotates slowly, reveals objects it “scans” with outlines or particle highlights

### Or even weirder:

#### 🧪 **Quantum Door**
Every time you enter, the room beyond is different. Pick from predefined layouts (procedural vibes).

#### 🧠 **Memory Echo Terminal**
Touching it replays past events as ghostly echoes (timeline ghosts, Niagara + skeletal ghost mesh)

What catches your fancy, Doctor Tripper? Want to go physical (terrain, particles), narrative (echoes, doors), or just get weirder (quantum garbage can that yells)?
Why dont we create a menu system that has a list of the meshes I have to build with and when selected places it in the world? Or is that a big bite to chew right now?
That’s **not a big bite** — that’s a perfectly chewable sandwich if we take it one bite at a time. You’re basically talking about a **modular mesh-spawner menu** — perfect for prototyping, level-building, or even in-game construction mechanics.

### 🧠 Breakdown: What You Want

✅ A **menu system** (probably a widget)
✅ That shows a **list of available meshes** (static mesh assets)
✅ When clicked → **spawns** the selected mesh into the world

### 🧭 Plan of Attack (Simple First Pass):

#### 🔹 1. **Make a Widget (e.g. WBP_MeshMenu)**
– Vertical box or scroll box
– Each button = one mesh
– OnClick → calls `SpawnMesh(meshToUse)`

#### 🔹 2. **Create a Spawner Actor (e.g. BP_MeshSpawner)**
– Has a function: `SpawnMesh(StaticMesh mesh)`
– Spawns an actor in the world with that mesh

#### 🔹 3. **Hook Widget to Spawner**
– In the level, assign the spawner to the widget
– Widget passes mesh asset to spawner → spawner creates it

### 🎯 Result:
Click a button → selected mesh appears in the world
(You can expand later with placement preview, rotation, etc.)

### 🔥 Optional Cool Extras:
– 🖱️ Click-to-place system: show ghost mesh and place where you click
– 🧱 Snap-to-grid or terrain
– 📦 Load mesh list dynamically from a folder using `Get Assets by Class`
– 🧭 Spawn at camera or in front of player

### ⚡ TL;DR Mini-Roadmap:

| Step | Task |
|——|——|
| ✅ 1 | Make `WBP_MeshMenu` with buttons |
| ✅ 2 | Each button sets a mesh var and calls `SpawnMesh()` |
| ✅ 3 | Create `BP_MeshSpawner` actor with a `SpawnMesh(StaticMesh mesh)` function |
| ✅ 4 | In widget, call that function on your placed spawner actor |
| ✅ 5 | Add to viewport and go nuts |

Wanna start with the widget or the spawner first? I can throw down a node layout or generate Blueprint code chunks.
NOt with widegets, I want only ingame so my character has control
Ahh—**no widgets**, only in-world, immersive controls? Beautiful. You’re talking about a **diegetic menu system** — a fully in-game tool your character can use to select and spawn meshes. Very Half-Life: Alyx meets Minecraft meets Giger.

### 🎯 What You Want:
– Player opens a mesh selection menu *in-world* (like a radial or 3D grid)
– Moves up to a mesh preview or steps on a pad
– Presses a key or uses trigger → **spawns that mesh** at a location

### 🧠 Your System, Reframed:

| Element | Unreal Equivalent |
|——–|——————–|
| Mesh choices | 3D actors in the world (displayed meshes, pads, etc.) |
| Player selection | Step into trigger or look at/select mesh |
| Spawn action | Button press or overlap triggers mesh spawning |

### 🛠️ Minimal Working Setup (No UI):

#### 🔹 1. **Build a “Mesh Display Room”**
– Create a new actor: `BP_MeshOption`
– It contains:
– A Static Mesh component (set to a specific buildable mesh)
– A Box Collision

#### 🔹 2. **When Player Overlaps Box**
In `BP_MeshOption`:

“`unreal
OnComponentBeginOverlap (Box)
→ Check if overlapping actor is Player
→ Store `StaticMeshToSpawn` in a variable on Player or GlobalManager
→ Print “Selected: [Mesh Name]”
“`

#### 🔹 3. **Player Places It**
In your Player Character BP:

– Add input (e.g. key press `E` or left-click)
– On input:
– Get `SelectedMeshToSpawn`
– Spawn `BP_PlacedMesh` actor at cursor or in front of player
– Set its mesh to `SelectedMeshToSpawn`

#### 🔹 4. **`BP_PlacedMesh`**
Simple actor with:
– A Static Mesh component
– Exposed variable `MeshToUse`
– On BeginPlay → Set Static Mesh to `MeshToUse`

### ⚡ Optional Flavor:
– Ghost preview mesh follows your crosshair
– Sound or light effect when spawning
– Raycast from camera for precise placement

### 🧪 Example Flow:
1. Walk into a lineup of 3D mesh options
2. Step near one (or look at it) → selection updates
3. Press `E` → mesh appears in front of you

### Want to Start?
I can mock up the first blueprint for `BP_MeshOption` or the player placement logic. You want the “step into selection” or “look and press” style first?
How do I move my unreal project files to another drive without breaking anything?
Good question — and yes, **you absolutely can move your Unreal project to another drive** without wrecking the space-time continuum *if you do it right*.

### 🧭 TL;DR: How to move an Unreal Engine project safely:

#### ✅ 1. **Close Unreal Editor**
Make sure the project is **not open** in the editor or in Rider/VS.

#### ✅ 2. **Copy the entire project folder**
Just grab the whole root folder (the one with the `.uproject` file) and paste it wherever you want on the new drive.

Example:
“`
D:UnrealProjectsMyCoolGame
“`

#### ✅ 3. **Update your .uproject shortcuts (if any)**
– Double-click the `.uproject` in the **new location** to launch
– Unreal will regenerate `.sln`, intermediate folders, etc. as needed

#### ✅ 4. **Fix launcher project list (optional)**
If you want it to show up in the Epic Launcher:

– Open the Epic Launcher
– Click **“Browse”** (top right of project list)
– Navigate to your `.uproject` in the new location → select it

### 🧨 Got C++? One Extra Step:

If it’s a C++ project:

#### ✅ 5. **Regenerate project files**
Right-click the `.uproject` file → **Generate Visual Studio project files**

Then:
– Open the new `.sln` from that folder
– Rebuild if needed — all paths will update

### 🧪 What *not* to do:
– Don’t move individual folders inside the project (like `/Content` or `/Source`) out of context
– Don’t open the `.uproject` while copying
– Don’t move the **engine itself** unless you’re intentionally relocating Unreal Engine installs (that’s a whole other mission)

Want a script or shortcut to automate future backups or syncs to another drive?
I need a REG file to turn on Move/copy to in my context
Boom, here you go. Here’s a ready-to-roll `.reg` file that adds **”Copy To”** and **”Move To”** to your right-click (context) menu in Windows **Explorer**.

### 📁 🔧 **REG File: Add “Copy To” and “Move To” to Right-Click Menu**

Save this as `AddCopyMoveTo.reg` and double-click it:

“`reg
Windows Registry Editor Version 5.00

; Add “Copy To” to context menu
[HKEY_CLASSES_ROOTAllFilesystemObjectsshellexContextMenuHandlersCopy To]
@=”{C2FBB631-2971-11D1-A18C-00C04FD75D13}”

; Add “Move To” to context menu
[HKEY_CLASSES_ROOTAllFilesystemObjectsshellexContextMenuHandlersMove To]
@=”{C2FBB632-2971-11D1-A18C-00C04FD75D13}”
“`

### ✅ How to Use:
1. Open **Notepad**
2. Paste the code above
3. Save it as: `AddCopyMoveTo.reg`
4. Right-click the file → **Merge**
5. Accept the prompts

Now, when you right-click on **files or folders**, you’ll see **“Copy To Folder…”** and **“Move To Folder…”** options.

### ❌ Want to Undo It Later?

Save this as `RemoveCopyMoveTo.reg`:

“`reg
Windows Registry Editor Version 5.00

[-HKEY_CLASSES_ROOTAllFilesystemObjectsshellexContextMenuHandlersCopy To]
[-HKEY_CLASSES_ROOTAllFilesystemObjectsshellexContextMenuHandlersMove To]
“`

Same process: save, right-click → **Merge** to remove it.

Let me know if you want to add this only for folders or only for files.
