2 item and 1 freeform combo scripts

I don't know how scripts work so a bunch of small ones should help.

I want on that makes a freeform combo more in certain.
It starts in the center and moves toward a random side until it hits the wall.
It then starts in the middle and chooses another random direction.
It will continue doing that untill the enemy in the room is killed.


I also think scripts are needed for these 2 items.
I want a candle that, when you use it it goes in all 4 directions at once rather than only in front.

The other item is a garlic like that in Castlevania 2.
When you drop it any enemy that hits it will stay at it until it does.

If these are added into a quest I could likely "decode" them.

EDIT:
I also have a couple custom enemies but I don't think they go in this forum
