Bro! Thank you so much. I’ve been trying for ages to figure out why I couldn’t make my tree solid when my character touched it. I had the correct colliders but I had the “is trigger” box checked the whole time because I didn’t know what that meant.

thanks mate helping with my school assignment a lot

If you don't have explosion animation just use this:


Debug.Log("Hit Detected");
Destroy(this.gameObject);
Scene scene =
SceneManager.LoadScene(0);


//I used this to reload the scene...will change it according to the game but for now it works good...
Thanks for these tutorials, I was able to learn a lot from these.
