Between those two spaces is the direction (0-360 degrees) it is facing. Sprite ID determines how something looks, while object ID (located two lines below sprite ID) determines how it acts in-game. There are two main types of IDs to look for: the sprite ID and the object ID.
If you are unfamiliar with using Notepad++, here's how it works: when you place down an item or enemy, its IDs are listed in the level.obj file for that floor. This is written assuming you are already familiar with it. If you haven't read any of my other guides involving Notepad++, I would recommend doing so before using the info found here. Not only that, but some bosses and effects are prone to crashing due to their complex nature.
Crashes can occur if incorrect numbers are put into Notepad++, or if a line is deleted. I would recommend testing out any levels altered with this guide before publishing them anywhere.
Just like the past three guides I've made, you will need Notepad++ to do anything this guide suggests.
