Weird GUI problem?
I have a script that when fired, makes a certain GUI visible. The script does what its told, and the "Visible" boxs becomes Checked when the script fires, yet the GUI still remains invisible
01 | cam = game.Workspace.cam |
02 |
03 | game.StarterGui.Cameras:WaitForChild("static") |
04 |
05 | cam.Changed:connect(function() |
06 | if cam.Value ~= 0 then |
07 | game.StarterGui.Cameras.static.Visible = true |
08 | local m = math.random(.01,.07) |
09 | while true do |
10 | wait(.1) |
11 | game.StarterGui.Cameras.static.ImageTransparency = m |
12 | end |
13 | end |
14 | end) |
Help?

math.random can only make integer
1 | --[[line 08]] local m=math.random(1,7)/10 |

math.random(low, high) requires that low and high be integers. If they're not, it just rounds1 them. It then picks an integer between low and high.
Much of the time, that's what you want -- it makes it easy to pick things from a list, etc.
If you want to have non-integer random numbers, you could just scale down, e.g.
1 | math.random(1, 7) / 100 |
2 | -- pick one of 0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07 |
However, this is not necessarily clear, and it can't pick any number, it can only pick a handful. You could add more by tacking on more 0s...
1 | math.random(100, 700) / 10000 |
but that's obviously not elegant.
If you want any random number, you should use math.random() which returns a random number between 0 and 1 (include 0, but not including 1). Thus to get a range from low to high, it looks something like
1 | low + math.random() * (high - low) |
In your case, that's
1 | 0.01 + math.random() * 0.06 |

It looks like it's round-towards-even, though that might not be platform independent ↩
