Sample scene errors

[Lyten02]

Unity version: Mac silicon 2022.3.4f1 I downloaded the project as a zip file and started the project without doing any other things

1. NullReferenceException: Object reference not set to an instance of an object LlamAcademy.Guns.GunScriptableObject.GetRaycastOrigin () (at Assets/Scripts/Guns/GunScriptableObject.cs:309) LlamAcademy.Guns.Demo.PlayerAction.UpdateCrosshair () (at Assets/Scripts/Guns/Demo/PlayerAction.cs:46) LlamAcademy.Guns.Demo.PlayerAction.Update () (at Assets/Scripts/Guns/Demo/PlayerAction.cs:41)

There are other errors there, just they are not so critical.

Hi! Have you followed the setup instructions to ensure you have the Unity Particle Pack installed and have a Particle System at the tip of your gun model? That error is commonly reported when the Unity Particle Pack has not been imported and a Gun model does not have a Particle System as a child.

The rest of your errors all seem to also point to a null reference related to the particle system.

Check the Quickstart on the readme and let me know if you still encounter the issue from there!
