How do I add to a Global Variable only once?

Hi,

In the game I'm working on a character is awarded trophies when certain conditions are met. How do I get the "add 1 to" a global variable the first time the conditions are met, instead of every time the event happens? "Trigger once" isn't working.

you will probably need to set another variable/array/dictionary indicating which trophies have been awarded. Only add 1 to your variable if they don't already have that trophy (and then set that they do have it when you add the +1).

Thanks AllanR.

Could you give a brief example of the above post using the variable option? It's not working for me and I find visual examples help a lot.

What do your conditions look like? Trigger once should work.

Allen described an achievement type system, which should also work. Basically it consists of:

Trigger Condition
If achievement=false

Add one to trophy
Set achievement to true

I followed the example and it's working now, thank oosyrag. I had a couple of things in the wrong order.
