Collision with 4 objects at the once

Hello,

how can I make collision with 4 objects at the once?

My solution is create variable and when I collision with 1 of the objects then I set value +1. When value is equal to 4 I do action but it is not good solution. I can't touch all 4 objects but if variable set to 4 then it makes action(s)...

I want make action only if I collision with all 4 objects at the once.

Why not add a booleoan instance variable collision and set it to true on collision.

Create an event that checks if all 4 objects boolean variable collision is true, if so perform action.

first idea
