Whenever I attempt to Target something like a left arm, I can't because it has a space in between Left and Arm, so how do I do it?
You can access them like you would indices in a table:
player.Character["Left Arm"]
MastaJames answered this well, but Im going to give it a shot of my own.
So normally when you are targetting something you would do
Player.Character.Head
but if it has a space in it, it can error. This is incorrect format.
Player.Character.Left Arm
That would error, and right there break your script. So to target the Left Arm, you will need to Add it in this format.
Player.Character["Left Arm"]
This successfully targets the Left Arm, and will not error.
I just took Mastas Answer and Made it longer explaining it in more detail.
Whichever answer you choose to accept will help you in the future.
