During the development of Super Stems I’ve had to deal with chain reaction. I started a battle with one tile, and if they win, the captured tile would start a battle, and this would happen recursively. For some reason, I have this battle method call on a different thread, in Unity’s terms, a Coroutine.
Now comes the question. How do I handle recursion with Coroutines? After looking around the doc and experimenting, I found a solution.
Here’s a sample code on how to make it work.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 |
public void StartBattle( ) { StartCoroutine(BattleRecursive(0)); } public IEnumerator BattleRecursive( int depth ) { // Start Coroutine" yield return new WaitForSeconds(2f); if( depth == 0 ) yield return StartCoroutine( BattleRecursive(depth+1) ); if( depth == 1 ) yield return StartCoroutine( BattleRecursive(depth+1) ); Debug.Log( "MyCoroutine is now finished at depth " + depth ); } |
After calling the entry point to your recursive method StartBattle, inside, you have yield return a new Coroutine call to the recursive method. This way, the execution order will be correct. Try it out and see for yourself.
Output should be.

// MyCoroutine is now finished at depth 2 // MyCoroutine is now finished at depth 1 // MyCoroutine is now finished at depth 0 |
