Negative Wake Up Distance

Hello guys i want to know how can i wake up some object in front of character without collide
If it can happen then plz share with me

 

put wake up as "Distance" on any object

 

I am talking about negative wake distance
I want to wake up enemy when character came near them

 

AS @Bilz636 said put a wake up distance on it,

 

Tried but not working always wake up after i pass it
I want to put wake up like -10 or -50

 

Because your doing -50 or-10, you need to do just 50 or 10,
Negative wake up will wake up an object when passing,

 

Ok i understand it worked thanks very much
I put less pixel so it was hitting character and when i increacedit by 100 then it worked
Again thank you very much for giving me time
