Creating Collectables in Unity

Let’s create a UI manager that shows the coin’s amount

Process

Coin

• Add a Rigidbody to the Coin gameobjects and set the isTrigger value to true

• Add a Coin script to them a with an OnTriggerEnter that checks if other.CompareTag(“Player”)
• If so, call UIManager.Instance.UpdateCoinsDisplay() and Destroy the gameobject

UI Manager

• Create a UI Manager script and add it to a Canvas gameobject
• Create a singleton
• Declare an int coinsAmount and a Text coinsText
• Create a method UpdateCoinsDisplay() that will increase coinsAmount++ and update the coinsText.text
