Ok the title is not that clear on what im trying to do.
So i wrote some code instantiating a a grid pattern in a rectaguar area, now im trying to on top of that grid floor to make some walls be instantiated, and i only want a variable percent to be covered.
Now i wrote some code that i thought would be correct. but nothing instantiates on top of my floor.
I thought that the code didnt work because maybe the grid had no child components till after the GameBoard(); had finished, so i used a if statement to delay the Wall(); from initializing till all the grid had been layed…
Would love some suggestions 
Have a great day and thanks for any help
