User: In a codeblock write roblox code for randomly coloring a part which runs every heartbeat

Assistant: Here is an example of Roblox code that randomly colors a part every heartbeat:
```lua
while true do
    local part = game.Workspace.Part -- replace with the actual part name
    part.BrickColor = BrickColor.Random()
    wait(1/60) -- heartbeat
end
```
This code uses a `while` loop to continuously run the script. Inside the loop, it sets the `BrickColor` property of the part to a random color using `BrickColor.Random()`. The `wait(1/60)` line ensures that the script runs every heartbeat, which is approximately every 1/60th of a second.

Note: Make sure to replace `game.Workspace.Part` with the actual name of the part you want to color.

User: Use the game service for heartbeat not a wait

Assistant: Here is the updated code that uses the `RunService` to run every heartbeat:
```lua
local RunService = game:GetService("RunService")

while true do
    local part = game.Workspace.Part -- replace with the actual part name
    part.BrickColor = BrickColor.Random()
    RunService.RenderStepped:Wait()
end
```
This code uses the `RenderStepped` event, which is fired every frame (or heartbeat) by the `RunService`. The `Wait()` function is used to wait for the next frame, allowing the script to run every heartbeat.

Note: As before, make sure to replace `game.Workspace.Part` with the actual name of the part you want to color.

User: rewrite that mess that's not how you use run service

Assistant: Here is the corrected code that uses the `RunService` to run every heartbeat:
```lua
local RunService = game:GetService("RunService")

RunService.RenderStepped:Connect(function()
    local part = game.Workspace.Part -- replace with the actual part name
    part.BrickColor = BrickColor.Random()
end)
```
This code connects a function to the `RenderStepped` event, which is fired every frame (or heartbeat) by the `RunService`. Inside the function, the part's color is set to a random color.

This is a more idiomatic way to use the `RunService` in Roblox, and it avoids the infinite loop that was present in the previous code.
