I want to print the WaveNumber such that is follows this order:
1
Next wave!
2
Next wave!
3
and so on…

Could anybody here help me? It would be much appreciated!

Your function returns a number. To print this, you would say:

print(WaveIncrease())

Since WaveIncrease is a function that returns a number, it will print the number!

Thanks to Benified4Life for pointing out that you have to have parentheses after a function for it to actually return a number! Thanks for the tip!

Just do

print(WaveNumber)

or if you want to print using the return:

WaveIncrease()

Hey there!

I don’t entirely understand what the usage case for this would be so any context would be appreciated. However, to answer your question you can simply use for i loops and print the iteration you’re currently in!

Example:

for WaveNumber = 1, TimesYouWantToRepeatThis do
    print(Iteration) --// This should print your current WaveNumber
    print("Next Wave!")
end

I hate to nit pick, however doing WaveIncrease will just return the functions memory address as it’s being passed as a variable. You’ll have to do WaveIncrease() to get a number return.

Yes, thank you so much for your help!
I’m trying to make a wave counter for a base-defense game.
I’m very new to coding so I may not be familiar with for i loops but it did help and I shall practice using that more often.
