How to activate a trigger (on/off)?

Hey!

I am making a game and I want my character to "activate" a trigger by collecting a couple of objects! So I want to have the trigger deactivated first and then with a script make it active??? But how would I do that? Can you turn triggers on and off by a script???

Very new to scripting :) And many thanks in advance! :D

I would suggest you take a look at the 3rd person tutorial as it has some item based logic similar to what you're trying to do. You have to collect a certain number of energy cells to complete the level.
