Random Integer from (-1.0 -> +1.0)

[d.healey]

@Chazrox This is one of the instances where the GPT is useful.

const randomFloat = (Math.random() * 2) - 1;

Console.print(randomFloat);

Explanation:

Math.random() generates a number in the range [0, 1].
Multiplying by 2 scales it to [0, 2].
Subtracting 1 shifts it to [-1, 1].

Thanks for this. That really helps me understand the logic. I get it now. Im gonna watch the other video you gave me and put this together. Thanks again!

@d-healey I cant figure out what to change.

[d.healey]

@Chazrox That * doesn't look right, did you copy/paste it from somewhere or are you using a different font?

This is how it looks for me

[Chazrox]

@d-healey I typed it out myself. Its an " * " right?

[Chazrox]

@d-healey I didnt change my font either. Thats default font.

@Chazrox What happens when you copy/paste those two lines to a new empty HISE file?

[ustk]

@Chazrox What do you have before line 7? sometimes an error ahead can appear later, for instance when a line of code isn't closed ;

[Chazrox]

@d-healey looks the same.
this is your code snippet copy/pasted.

looks the same.

Yes, but does it work in the new project?

[Chazrox]

@ustk I been changing each one to test but it wasnt working. Trying it in a new snippet per David rn. My lines are closed up above.

[ustk]

@Chazrox Since it's a namespace, maybe it's in the main script... The console is definitely saying something about a missing semicolon so...

[ustk]

@Chazrox And when you compile, is the focus on the script? meaning not "(detached)". This happens when you edit another script at the same time, so the modifications aren't compiled.
I find myself being tricked a lot by this everyday... "why the heck this isn't working... Oh ok... silly me..."

@Chazrox Don't use var for variables except when you have no other choice

@d-healey @ustk

I got it to work. I moved it to main script and it worked outside of the namespace. literlaly copy/pasted it out and it worked there. I put it back into the function and made randomFloat a local and it worked.

Sometimes I dont even understand how things are fixed but they get fixed.

[Chazrox]

@d-healey sorry that pic was cut off. They're const vars for sure. I remember you teaching that in the tutorial.

[Chazrox]

More than just helping me fix the problem. I always appreciate the logic! You guys are the best!

you mean am I compiling while on the main script?

I havent seen that "detached' yet. My namespaces are local (external scripts) to the project. Would that apply to this situation?

If im working within a namespace i'll usually do both for good measure...atleast I think thats good measure. lol.

@Chazrox detached appears when you have more than one script in the module list. If you click in the module list to modify another script, or show its network for instance, this detaches the other scripts currently being edited. So if when you make a change, it's not compiled until you "re-attach" the script from the module's list and re-compile.
