How to use textboxes to write certain things?

You could use a localscript to check if there is anything in the textbox and then check if the text you want is in the textbox

basically like this

local textbox = script.Parent.Parent.Textbox --Finds Textbox

textbox.Changed:Connect(function()--Creates a changed function
if textbox.Text == "thewordyouwant" then--checks if the right word is in textbox
    --make it do what you want here
    end -- ends the if statement
end) -- ends the function
