Random positive/negative numbers?

[Chuckleberry_Finn]

Hi,

Is there a function like FRand() that will return a random number between, say -1.0 and 1.0?

Right now I have to use two FRands(), one to generate the number and one to generate it's sign. Just wondering if there's a function that does all that automatically. I didn't see it listed in the tech reference.

Thanks.

Use 2*FRand()-1

I put this function in whatever classes I need random signed numbers in.

function int RandSign(int num)
{
if (FRand() > 0.5)
return -1 * Rand(num);

return Rand(num);
}

Look what I found in Object, line 303:

native(1033) final function float RandRange( float Min, float Max );

Hot damn, Wormbo. That's what I was looking for

Thanks all.

****ing ****. I was wondering why that was in the C++ headers and not in UnrealScript. I never checked it out in Object.uc.
