How can I start my game with no jumping, but earn it after touching a box trigger?

What it said in the title, plus the fact I’m using the third person template, and have already placed the trigger.

just use some kind of flow control. you could use a gate or a branch for example. if you used a branch then you could pair it with a bool variable and when the player enters the the trigger you set the bool to true.

Thanks! I think I know how to do it, I just needed the idea!
