update:
I’ve got the creation blueprints and variable of number of houses at start done, just haven’t figured out how to destroy three of them at random.
This is an array created at start, I haven’t figured out what to do with it. I use a int variable which you can see in the 2nd pic to keep count of the number of houses at present.
And this is what I’ve got so far to destroy the houses. So how do I implement the array and choose three of them at random to destroy? Thank you!
