The "Show Rayfield" button - Sirius Docs

If a script you run uses Rayfield and you hide its window, a button reading Show Rayfield appears at the top of the screen. Tap it and the window comes back. The button only appears on touch devices, such as phones and tablets. Some scripts change the label, so it may say Show followed by the script’s own name.

Bring the window back

Mobile
PC

Tap Show Rayfield at the top centre of the screen.

For script developers

The button label comes from ShowText in CreateWindow, and the PC key from ToggleUIKeybind. See windows.

local Window = Rayfield:CreateWindow({
   Name = "My Script",
   ShowText = "My Script", -- the button reads "Show My Script"
   ToggleUIKeybind = "K",
})

You can also hide and show the window from code with Rayfield:SetVisibility.
