Well,if you change properties through a script some bugs could be prevented.
First we need to find where is block placed.
Usually when you spawn it is in Workspace.
If you have multiple objects named for example "Block" rename one of them OR add number behind them.
It will prevent changing multiple objects at once.
Into script you should specify where is the block placed.
Make local variable.
You can change "block" to anything you like!
local block = game.Workspace.Block
--Also this script below will also work!
local block = workspace.Block
Now find which property you want to change.
Let's say we want to change Transparency.
We would type this: (Also keep in mind previous part of the script is needed!)
local block = game.Workspace.Block
--Also this script below will also work!
local block = workspace.Block
block.Transparency = 1
Now transparency is changed to 1!
You can edit other properties like this!
It is my first tutorial :D
Have fun learning!
