Getting a unique random number from within a table?
Is there any method of creating a unique random number every time it is called from in a table? I'm currently using:
["Main"]= CFrame.new(1.26865196, -0.568903923, -2.47046661, 0.995743334, 0.0894539207, -0.022211533, -0.0921702608, 0.96639806, -0.239957407, 5.04754247e-008, 0.240983203, 0.970529377),
as a means of animating a part, however trying to use something like:
["Main"]= CFrame.new(math.random(1.24865196 , 1.28865196), -0.568903923, -2.47046661, 0.995743334, 0.0894539207, -0.022211533, -0.0921702608, 0.96639806, -0.239957407, 5.04754247e-008, 0.240983203, 0.970529377),
leaves me with only 1 random number, which is countinually called. Is there any way I can ensure that this is a random number?

Enter, functions
Whilst you're out of luck if you want to do this so that every time you access yourTable.Main it has the CFrame with a different random number, you can instead have Main be a function which returns the new generated CFrame.
math.random doesn't play nice with fractions
Yes, I know, annoying. You can probably use a lerp for this, however.
CFrame.new(1.24865196 + (1.28865196-1.24865196)*math.random(), -0.568903923, -2.47046661, 0.995743334, 0.0894539207, -0.022211533, -0.0921702608, 0.96639806, -0.239957407, 5.04754247e-008, 0.240983203, 0.970529377),
What that will do is choose a random number between 1.28865196 and 1.24865196 by using the fact that math.random already makes a fraction between 0 and 1, and applying it to a simple lerp.
