# Sleep in Lua Roblox

#### You:
how to sleep in lua roblox

#### ChatGPT:
In **Roblox Lua**, there isn’t a true “sleep” function like in some programming languages, but you *pause execution* using built-in timing functions.

### ✅ 1. `task.wait()` (recommended)

This is the modern and best way.

```lua
print("Start")
task.wait(2) -- pauses for ~2 seconds
print("After 2 seconds")
```

You can also do:

```lua
task.wait() -- waits for next frame
```

---

### ⚠️ 2. `wait()` (older, not recommended)

This still works but is deprecated-ish and less accurate.

```lua
wait(2)
```

---

### ✅ 3. Frame-based “sleep” using RunService (advanced)

If you want precise frame control:

```lua
local RunService = game:GetService("RunService")

local start = tick()
while tick() - start < 2 do
    RunService.Heartbeat:Wait()
end
```

---

### 🧠 Key idea

- Roblox scripts are **event-driven**, not blocking like traditional programs.
- “Sleeping” just means *yielding the thread* until time passes or an event fires.

---

### 👍 Recommendation

Use this almost always:

```lua
task.wait(seconds)
```

If you want, tell me what you're trying to build (NPC, GUI, animation timing, etc.), and I can show the best way to structure delays for that case.
