I'm trying to run an function only once when a score turns to 1 (or another number)

I'm doing this so I can run a function that loops an animation (exported from BDE Engine website for animating display entities). Is there a way to do this without continuously running that function every tick, or a better way to go about running the animation function in general? Sorry if I sound a bit confused, I'm pretty new to datapacks

Could use an advancement

But without more context I don't think I can provide a better suggestion, I don't really understand the problem

Sorry, I shouldve been more clear lol. Right now I have an advancement that runs a function and it keeps repeating while i'm holding right click

But how can I execute a function to run once when the right click starts and ends (so I can play the animation then go back to playing the idle)

Conure dd a video a while back on how that can be implemented
