How do I Scale a GameObject over time?

Questions & Answers

I’ve managed to get my gameobject to scale, but I would like to scale it bigger over the course of lets say 1 second but I don’t know how to do that since I’m extremely new at scripting. Here’s my code

public class Enlarger : MonoBehaviour {

public GameObject Player;

void OnTriggerEnter(Collider other)
{
	
	print("Collision detected with trigger object " + other.name);
	PlayerComponent playerComponent = other.gameObject.GetComponent<PlayerComponent> ();
	//checking if collided with player
	if (playerComponent) {
		Player.transform.localScale = new Vector3(2.0f, 2.0f, 2.0f);
		Destroy (gameObject);
	}
}

}

Any and all help is very welcome.

You could do it using coroutines and Vector3.Lerp

public class Enlarger : MonoBehaviour {

	public GameObject Player;

	void OnTriggerEnter(Collider other)
	{
		print("Collision detected with trigger object " + other.name);
		PlayerComponent playerComponent = other.gameObject.GetComponent<PlayerComponent> ();
		
		//checking if collided with player
		if (playerComponent) {
			StartCoroutine(ScaleOverTime(1));
		}
	}
	
	IEnumerator ScaleOverTime(float time)
	{
		Vector3 originalScale = Player.transform.localScale;
		Vector3 destinationScale = new Vector3(2.0f, 2.0f, 2.0f);
		
		float currentTime = 0.0f;
		
		do
		{
			Player.transform.localScale = Vector3.Lerp(originalScale, destinationScale, currentTime / time);
			currentTime += Time.deltaTime;
			yield return null;
		} while (currentTime <= time);
		
		Destroy(gameObject);
	}
}

This way it will throw a coroutine that will scale the player object frame per frame over time until it gets to its desired scale.

I have a YouTube video about this - YouTube it only requires a few lines of code
