How do I call a function when another function is executed?

I am trying to make it so that each round you are in at the end of each round everyone dies from one explosion. I have a Function called InRound that determines if we are in a round. How would I make it so that when one function ends it calls the other function (explosion) to execute?

You can just call the second function at the end of the first one. Like this

function InRound()
	print("In round check")
	ExplodePlayers()
end

function ExplodePlayers()
	print("Players exploded")
end

-- Just call InRound and it will do both
InRound()
