There are many ways to make a brick glow. This tutorial will explain the concept of making things glow using scripts.
The Reflectance GlowEdit
while true do for i=1, 9, 1 do -- Go up script.Parent.Reflectance = i * .1 wait(.1) end for i=9, 1, -1 do -- Go down script.Parent.Reflectance = i * .1 wait(.1) end end
-- Go up and -- Go down are both preceded by double hyphens. Anything preceded by double hypens are ignored by the computer. Comments can help people by describing the purpose of a section of code, but the script will work just as fine with or without the comments.
for i=1, 9, 1 do script.Parent.Reflectance = i * .1 wait(.1) end
"i=1" means that the script is making a variable, which is, a value that can change as the script progresses. In this case, "i" will start at 1, and will increase everytime the "for loop" loops. It will go to 9 (notice the next statement, ", 9"), increasing in units of 1 (or, as in the second loop, decreasing by 1) and then stop the loop.
script.Parent.Reflectance = i * .1
This is just setting a value, but with a catch: we're setting it to a variable. Variables are assigned numerical values. (Note the "* .1". That's to make it ".1" when i is 1, and ".4" when i is 4, for example. A decimal is just another way to write a fraction.
This is how the loop can be reversed:
for i=9, 1, -1 do -- Go down script.Parent.Reflectance = i * .1 wait(.1) end
The loop goes from the value of 9 to the value of 1, decreasing in units of 1 each time.
