1

Create a button in your UI Canvas

Select UI Canvas in the Hierarchy panel.
Right-click and choose UI > Button to create a new button.

2

Hide the button by default

Select the button in the Hierarchy panel.
In the Inspector panel, uncheck the checkbox next to the button's name to hide the button by default.

3

Create a New Logic script

In the Project panel, select the My Logic folder.
Select Add (+).
Select Script. Unity Studio creates a new Logic script in the folder.
Enter a name for your script and press Enter.

4

Add the script to a GameObject in your scene

Select or create a GameObject from the Hierarchy panel.
From the Inspector panel, select Add Component.
Choose your Logic script from the list.

5

Set up the logic in the Logic Editor

In the Project panel, double-click the Logic script to open the Logic Editor.
Drag a When event listener into the Logic Editor.
Add a Play Starts event inside the When node. This triggers the logic when the application starts.
Drag a Wait node inside the When node.

seconds. This adds a delay.
Create a new variable for the Button, and set its type to Object.
Expand the button variable properties and methods.
Drag the Set Active method into your logic chain, and set it to true.

Connect your Button reference

In the Hierarchy panel, select the GameObject that has your Logic script attached.

Press Play to test your scene.
