For Loops & Transparency
Pretty simple question: How do I make the Parent of this script (Which is a transparent Part) turn opaque with steps of 0.1 and a speed of 0.1 seconds.
1 | for i=1,0, -0.1 do |
2 | script.Parent.Transparency = (i) |
3 | end |

Your script works fine, the only problem is you aren't waiting! ROBLOX has this nice function named wait which halts the script for the amount of seconds input into the function. This is useful for pauses of all kinds, including the one you want!
1 | for i=1,0, -0.1 do |
2 | wait(0.1) |
3 | script.Parent.Transparency = i |
4 | end |

Note that because this will loop 10 times, it will result in a total time of 1 second. Bubby4j 231 — 11y

How do I make it so the loop only runs until the Parent is opaque? So it won't turn transparent again, that is. RSoMKC 45 — 11y

Use a while loop instead of a for loop. Set the condition to a check to see whether or not the part has reached its desired transparency. Unclear 1776 — 11y

1 | for i=1, 10 do |
2 | wait(.1) |
3 | script.Parent.Transparency = script.Parent.Transparency + 0.1 |
4 | end |
This will add 10% transparency to the part every 1/10th of a second

Simple:
1 | for i=1,0, -0.1 do |
2 | script.Parent.Transparency = (i) |
3 | wait(.1) |
4 | end |
Or if you mean .1 seconds for the whole thing:
1 | for i=1,0, -0.1 do |
2 | script.Parent.Transparency = (i) |
3 | wait(0.01) |
4 | end |

Wasn't aware that the wait() was needed over there, thanks! Now that I'm looking at the loop a bit better I feel stupid. RSoMKC 45 — 11y

You can calculate the time needed to wait like this. I included nice variables so you can change it up easily.
1 | local speed = 0.1 --Time in seconds |
2 | local stepsize = 0.1 --Step size |
3 | for i = 1, 0, -1*stepsize do |
4 | script.Parent.Transparency = i |
5 | wait(speed*stepsize) |
6 | end |
If you want a function, here you go:
01 | function animateTransparency(part, seconds, stepsize, endTransparency) |
02 | while part.Transparency != endTransparency do |
03 | if part.Transparency < endTransparency then |
04 | if part.Transparency + stepsize > endTransparency then |
05 | part.Transparency = endTransparency |
06 | else |
07 | part.Transparency = part.Transparency + stepsize |
08 | end |
09 | else |
10 | if part.Transparency - stepsize < endTransparency then |
11 | part.Transparency = endTransparency |
12 | else |
13 | part.Transparency = part.Transparency - stepsize |
14 | end |
15 | end |
