Collect a coin go to the next level

I want a script that, when collecting a certain coins activates a portal to go to the next level, this is the logic;

 

Code (CSharp):

1. if (certain coin)
2. {
3.   go to next level
4. }

 

You have an OnTriggerEnter somewhere in which you detect whether you collect the coin. When the coin was collected, spawn your portal. When the player touches the portal, load a new scene. Where is your problem?

 

https://docs.unity3d.com/ScriptReference/MonoBehaviour.OnTriggerEnter.html
https://docs.unity3d.com/ScriptReference/SceneManagement.SceneManager.LoadScene.html

Those should have everything you need.

 

I'll give you an example, I have 10 coins scattered in the game environment, collecting the 10 coins activates a portal that goes to the next level! And only in this way to move to the next level, this is the logic I want (similarly donate collecting a key that will open a door to advance, only I want it with coins)

 

Does using the for attribute to collect a coin, carry it to the next level also work? And the Set Active to open the portal will it work?

 

I basically already told you how to do this. Somewhere in your coin collection code you check for collision with the coins, probably using an OnTriggerEnter. Here, if all coins are collected, spawn a portal. When touching the portal, load a new scene.

The easiest way to check if all coins are collected is to save the amount of collected coins in a public static (which is globally accessible from everywhere) variable. This is not very object oriented tho, so you can also approach the problem by introducing a sort of CoinCollectionManager class, which is known to all coins. When a coin is collected, it calls some method in the CoinCollectionManager, which increments the amount of collected coins, and then if all coins are collected, spawns the portal. Either of those approaches is fine. I'd personally go with the manager type class and make it a Singleton.

If you need help with any of the above, feel free to tell us with what specifically.
