Title: How do I make Random Float always end on an ODD number?
Post by: 4ppleseed on February 12, 2017, 05:12:20 PM

Hi all,
I saw on the Ecosystem there is a Random INT odd/even.

What I need is to make a float that always ends in an odd number. So 1.1 2.1 3.1, 1.3 2.3 3.3, 1.5 2.5 3.5, 1.7 2.7 3.7 etc would all be acceptable.

Any ideas for making a Random Float range between -5.0 and 5.0, always end on an ODD number?

Thanks  8)

One ugly way of doing it is using an "Int Switch" where you manually input the even numbers in your range. Then send said even numbers to a send event that will add +1 then have it go back into the "Int Switch" where there is odd number send event that goes to the rest of your script.

Then do a convert to float.

Yeah, I tried something like this but you can't then combine two INTS into a float.

Lets say I do Random INT and get 2
Then do another Random INT and get 4, which a reroll until ODD so then get 5

How would I combine the INT 2 and the INT 5 to make the FLOAT 2.5

I need to be able to generate a FLOAT with one decimal place that is always ODD.

1.5, 2.9, 3.1, 4.7, 5.3 etc...

Get random int #1, convert to float.
Get random int #2.
Convert int #2 to float and divide with 10, you get 0,x
Then float #1 + the new float #2.

That won't guarantee the last digit is an ODD number, will it?

Combining 600's and midgear's approaches would let you do it. Another kind of messy approach would be to

- convert the float into a string
- take the last character of the string ("string take n from right" is what it's called iirc)
- convert it into an int
- test it for even/odd
 -> proceed with float if true
 -> get next float if false

I can't think of any currently available actions that would let you do this in a neat/tidy way.

Thanks for your help - I actually gave up in the end haha.

I managed to sorta get it to work by adding a pixel to the sprite then using round to nearest 0.2 which then makes the float EVEN - which I can now use to line things up.
