I just KNOW that I'm going to kick myself for not being able to find this, but for some reason, there's an rnd command in this code (closer to the end) that ALWAYS comes up 0. It's the variable 'zsroll.' The actual call for the rnd is:

zsroll = rnd(zs)

I even added this to the code, as you can see:
If zsroll < 1 then zsroll = 1

But it still comes up as zero.

I wrote a simple little five line thing, like

-----------------
a = 5

do
print rnd(a)
cls
loop
-----------------

And it worked fine, so I really don't know what I'm doing wrong. I'm sure it's just a typo that I've failed to grab while coding in the middle of a catatonic 3 a.m. stupor, but regardless, any help will be greatly appreciated. Thank you, everyone.

I will eat your flesh.

You define Zhit$ at the start of you programme when zsroll=0 so you will always get 0 even though zsroll is returning a random value in your subroutine.

Rather than having:
zhit$ = "You attack the human for "+str$(zsroll)+" damage!"
at the start of your code.

Try:
center text 320,160,"You attack the human for "+str$(zsroll)+" damage!"
in your Attack and defend subroutine.

EDIT:
Use:
randomise timer()
at the start of your code to ensure you get a different set of random numbers every time your programme runs.

For a random number between 1 and 5 you did this:
zs=5
zsroll=rnd(zs)
if zsroll < 1 then zsroll = 1

This will do the same:
Zs=4
Zsroll=rnd(zs)+1


EDIT2:
I missed this:
Quote: "I even added this to the code, as you can see:
If zsroll < 1 then zsroll = 1

But it still comes up as zero."



Sorry I just woke up in my comp chair with a stiff neck. I really must go to bed sometimes. Im told beds are quite comfortable.

Oooh, thank you. Didn't realize that strings set things in stone.

You can sleep when you're dead.

Thank you very much for the help; now I can actually continue.

lol

A couple of weeks ago I fell asleep with my leg resting on the corner of my desk. I spent most of that day limping as a result.

Ugh. Now I'm getting a nesting error. I swear, either I'm the most impulsive/codependant progger ever, or DB just likes to make problems for me. My guess would be the former. If anyone could give this a readthrough, I'd be very thankful... I think I'm just missing an endif or I have a 'return' in the wrong place (I was told once that 'gosubs' are a trap... maybe that was something else... can't remember...). There are some small codes that might seem placed sporatically; this is just because I was trying to identify the problem.

And I totally fell asleep right next to the comp. I'm having trouble finding my lower body.

In this code:


There is a missing endif.
