Unity3D - Mission System

Hello Unity Community :slight_smile:
There is anyone that can help me with a script to manage simple mission?
For example: the player must pick up 3 boxes with some ammo and gun and have to put it in a specific place.
For example

var ObjectToPickUp : int = 3;
var Object : GameObject;

And after taking the object you have to put it in a specific zone, so with trigger.
when you enter in the trigger, appear the next object to pick up…
Like in dead trigger mission
Thanks :slight_smile:

This is what are you lookig for
