hi i am making a random event generator and i have a few problems that needed fixing.
First i am in need of a random function that is customizable
Or a code for making random numbers but in a variable like %_Rand%
also i need about like 7+ or more random codes for different amounts of numbers allowed in the code and stuff.
I am getting really good at Batch but still need help.. a lot of help
If you need my code just ask just because i am affraid someone will steal this code and post a program before me if there is a pm function then i will give you the code through there

OK seriously i need help with this plus when i am done this entire program i was going to post it for free of use too... sad.gif

Why are you waiting to show your code?

If you show it, you're more likely to get a response~

No one's going to steal it. Look at it this way~

You need help with it, therefore it doesn't work properly. Why would someone steal that? wink2.gif

You might want to look into the modulus operator. I think this is what you're looking for.

Basically, set /a var = %random% %% 5
So this way, var (in theory) should be between 0 and 4 inclusive.

Now, you can perform if to do something like so:
CODE
set /a var = %random% %% 5
if var == 0 (echo windy)
if var == 1 (echo sunny)
if var == 2 (echo you got struck by lightning)
if var == 3 (echo it's raining cats and dogs!)
if var == 4 (echo better wear your sun cream!)


It's been a while since I did batch, so let me know if this isn't what you're looking for.

You're looking to make one random number between 1 and 7, and perform an if statement to output one particular thing, correct?

set /a var = %random% %% 7
The available numbers will be:
0, 1, 2, 3, 4, 5, 6

So, perform an if on each of those to determine what needs to be performed.

I'm off until tomorrow now, but I'll check back to this thread as soon as I come back. smile.gif

Edit:
My bad~ I told you it's been a while. Here, this should work to give you an idea:
CODE
@echo off
set /a var = %random% %% 5
if %var%==0 (echo windy)
if %var%==1 (echo sunny)
if %var%==2 (echo you got struck by lightning)
if %var%==3 (echo it's raining cats and dogs!)
if %var%==4 (echo better wear your sun cream!)
pause


Hope this helps smile.gif
