Question

Ok I created a brick
Area
Srpite
CollisionShape2D

now when i am standing under it and jump up
1 to 5
each time I hit the brick (I.E enter the Area ) I get a random number of coins ( 1 to 10)
and makes a sound
on the 5 time the brick breaks (I.E dis-appears form the screen)

Answer 1

Block needs to have a variable referring to its durability.
Every time a collision occurs this variable goes down one number and script checks it :

pseudocode

on collision :
     play sound
     give random amount of money
     if durability == 0:
           queue_free()
     durability -= 1
