Creating a single use ability!
Easy question: yet I don't know the answer!
How to create a one-time only ability that will permanently disable itself after first use?
To clarify, it will have no cost, and I don't want to put a 9999999 sec cooldown time as it looks HORRIBLE in game!
What I want in nice terms...is for the DOME upcoming game mode. I would like to have invulnerable structures (easy to do) which once you capture, trigger an ability (easy to do) which calls in reinforcments but then disables itself permanently (HARD PART) or until lost...since it cannot be abandonned!
Help?
Thank you!
