How do I make a random local variable on a loop For ?

Hello Everyone,

I am confusing, I need to Set a random value on a local variable inside a loop "For", but is not working.

When I put a constant value or I add the value, it is working. but, when i want to use "random" it is the 0 value returned.

I hope you can explain me what is the problem

Best regards

Use floor(random(0,Dictionary.KeyCount)) or floor(int(random(0,Dictionary.KeyCount))) instead and see what happens.

Are you sure the dictionary is well filled and the keyCount is returning a valid value?

Your loop should be from 0 to Array.Width-1 also.

And the "loto" variable is used before receiving its random value. You should reorder things a bit otherwise 0 will always be the first number.

Use floor(random(0,Dictionary.KeyCount)) or floor(int(random(0,Dictionary.KeyCount))) instead and see what happens.

Hi Josek5494

Yes Great! The "floor" is exactly what I need, now it is working properly.

So many thanks!

Thank you for your comment. The Array.width is 1000

If I use "Array.Width-1", I have 0 to 998 so 999 values in X (Debug layout). But in my case I want to have 1000 values exactly (0 to 999).

Use floor(random(0,Dictionary.KeyCount)) or floor(int(random(0,Dictionary.KeyCount))) instead and see what happens.

Again,

I want to understad Why "random" is not working without floor. My first think is because the "random" use decimal value, isn't it ?

Thank you to help me to understand better my error.

Yes, random returns a value, which can be decimal. For example: random(0,2) can return 0.01 , 0.02 , 0.5 , 1 , 1.09...

"For" is inclusive, so it will run from 0 to 1000 if you use 0 to Array.Width, that's why you need 0 to Array.Width-1.

Hi Blachornet

Yes you are right, I have trying with Array.Width-2 and the latest value is 0.

Thank you very much to help me, master
