This example will demonstrate how you can listen for the various events of a UI button object. This example will also show you how to change the text in a UI Button by using the text property of the UI Button.

-- Make the cursor visible
UI.SetCursorVisible(true)

--Allow the cursor to interact with UI
UI.SetCanCursorInteractWithUI(true)

-- Get the UI button object so that its events can be listened to
local propUIButton = script:GetCustomProperty("UIButton"):WaitForObject()

-- This function will be called whenever the button is click
function OnClick(button)
    print("The button has been pressed")
end

-- This function will be called whenever the player presses down on the button
function OnPress(button)
    -- Change the text displayed by the button
    button.text = "Button is being held"
end

-- This function will be called whenever the player releases their mouse after having
-- held it down over the button
function OnRelease(button)
    -- Change the text displayed by the button
    button.text = "Button was released"
end

-- This function will be called whenever the mouse passes over the button
function OnHover(button)
    -- Change the text displayed by the button
    button.text = "Mouse is over button"
end

-- This function will be called whenever your mouse passes off of the button
function OnUnhover(button)
    -- Change the text displayed by the button
    button.text = "Mouse off of button"
end

-- Bind the "OnClick" function to the "clickedEvent" of the button so that clicking on the
-- button fires the "OnClick" function
propUIButton.clickedEvent:Connect(OnClick)

-- Bind the "OnPress" function to the "pressedEvent" of the button so that the "OnPress" function
-- is fired immediately after the mouse is held down and on top of the button
propUIButton.pressedEvent:Connect(OnPress)

-- Bind the "OnRelease" function to the "releasedEvent" of the button. This will cause the "OnRelease" function
-- to be fired whenever the left mouse button is released while the mouse is above the button
propUIButton.releasedEvent:Connect(OnRelease)

-- Bind the "OnHover" function to the "hoverEvent" of the button. This will cause the "OnHover" function to be
-- fired whenever the mouse passes over the button.
propUIButton.hoveredEvent:Connect(OnHover)

-- Bind the "OnUnhover" function to the "unhoveredEvent" of the button. THis will cause the "OnUnhover" function to
-- be fired whenever the mouse leaves the button.
propUIButton.unhoveredEvent:Connect(OnUnhover)

Example using:

`SetButtonColor`

`unhoveredEvent`

This example will will show you how to change the color of a button by using the SetButtonColor method. It's important to remember that colors in Core use red, gree, and blue values between 0 and 1 as opposed to values between 0 and 255.

-- Make the cursor visible
UI.SetCursorVisible(true)

--Allow the cursor to interact with UI
UI.SetCanCursorInteractWithUI(true)

-- Get the UI Button object
local propUIButton = script:GetCustomProperty("UIButton"):WaitForObject()

-- The button will switch to this color when the mouse leaves the button
local MouseOffColor = Color.New(0.5, 0.2, 0.4)

-- This function will be called whenever the mouse leaves the button and set
-- the color of the button to the color of "MouseOffColor"
function OnUnhover(button)
    button:SetButtonColor(MouseOffColor)
end

-- Bind the "OnUnhover" function to the "unhoveredEvent" of the button. THis will cause the "OnUnhover" function to
-- be fired whenever the mouse leaves the button
propUIButton.unhoveredEvent:Connect(OnUnhover)
