BASICS
1. To spawn items into the game you must be in 'Admin mode"
{To enter admin mode type:~~> /admin <~~"}
2. The command to spawn any item in the game is ~~> /spawnitem <~~
3. Basically every single item in the game has a spawn id [Note: The name of the item will not match it's spawn id] This is a link I used to find any ids https://starbounditems.herokuapp.com/
4. When typing the spawns for the code spacing is important, there are some places that require this and some that won't. I can't tell you all the places, but tinker with what works -_^ !
5. If you are afraid of crashes, then you should make a seperate world to test the spawns before trying it on your main account, I lost a couple characters when fiddling with the particles.
[b][Ctrl + C][/b] and [b][Ctrl + V][/b] You must know how to copy an6. Use [Ctrl + C] and [Ctrl + V] You must know how to copy and paste.

IMPORTANT RULES TO NOTE WHEN CUSTOMIZING
So if you want to begin changing an item you must have these brackets around the changes: ~~> '{ }' <~This box must come after the amount and must be at the end of the command.
You will need "parenthesis" around most commands and to be separated by commas ','
Colons ':' are used to link a command to another command.
How You Can Orginize Your Items:
noice: I am not telling you how orginize your items, this is just how I did it. Knowing this can help out those who might lose there custom armors.
If you are going to get into this, You should create a Word Document or Notepad that contains items you created. This will allow you to spawn items that you saved in the past and can be a reference, or you can send the items to other accounts / characters. This image shows me editing some items that can be created in game-- through copy and paste into the chat "Thank the devs for adding copy and paste."

Note: For this part of the guide I will use the item "Heart Wreath" because I am quite fond of it, you can not obtain this items legit though because it is a seasonal item.
--------------------------------------------------------------------------------------------------------------------------
PART ONE: BASIC

To spawn this item you must type:

/spawnitem cupidshead 1

Very simple, it's just the [spawn command] [item ID] [Amount]
NOTE
The purpose of this shot is to show you what the items looks like.(Please ignore the absurd things that are happening to my character, I sort of screwed up the picture so this is a re-take, apologies)
--------------------------------------------------------------------------------------------------------------------------
PART TWO: NAME, DESCRIPTION, AND RARITY
Next to spawn items with a new title, descriptions, and change of rarity:


/spawnitem cupidshead 1 '{"shortdescription":"Title","description":"Caption","rarity":"Essential"}'

Okay let me explain this command in chunks:
[spawn command] [item ID] [Amount] [Change Title] [New Title Name] [Change descrition]
[New Description] [Change Rarity] [Rarity]
--
Note: you can't use any of these -> { ( ' ) } <- in the name of your items because they are part of the code.
Edit:You can indeed add apostrophes in item descriptions.
By using \ immediately prior.

Example:
"description":"It\'s an item description with an apostrophe!"
--
The command for Rarity does not have to be "Essential"

You can change the color of the Rarity by inserting the commands below for rarity:
"Common" = White
"Uncommon" = Green
"Rare" = Blue
"Legendary" = Purple
"Essential" = Gold
--------------------------------------------------------------------------------------------------------------------------
PART THREE: STATS
For this part I made it so thiat this Vanity armor (armor with no stats) includes it's own stats:

/spawnitem cupidshead 1 '{"shortdescription":"Buki HeadBand","description":"Made By Buki","rarity":"Essential","statusEffects":[{"stat":"protection","amount":100},{"stat":"maxHealth","amount":100},{"stat":"powerMultiplier","baseMultiplier":10},{"stat":"maxEnergy","amount":100}]}'

Here are the components:
[spawn command] [item ID] [Amount] [Change Title] [New Title Name] [Change description]
[New Description] [Change Rarity] [Rarity] [statusEffect] [stats] [protection] [amount] [number] [stats] [maxHealth] [amount] [number] [stats] [powerMultiplier] [baseMultiplier] [number] [stats] [maxEnergy] [amount] [number]

Small Notice
This part is honestly tough, because of all these brackets and what not, You should tinker with what works for you.
Balancing
You don't have to use this part if you don't want stats (but I would leave it at 0 for protection, health, and energy, but leave the multiplier at 1 to not decrease your damage if you don't want anything on it)
If you want to stay balance, go on the wiki and insert stats of the tier equipment you want (I am at late game, so I normally plug in perfect armor gear)
If you want to be unbalance and beat the crap out of your pvp friends, I suggest you use only 5 digits for the numbers because that is all you will need to wipe them (unless they used something like this to mod their gear too).

What is a Status Effect?
A status effect is like a buff, (exp: glowing, jump boost, running boost, damage boost, etc). These buffs are similar to what the game would apply only, it will stay active as long as you are wearing the armor. I would like to point out that this is different from particles, which is covered in the next section.
Example of item with status effect:

/spawnitem cupidshead 1 '{"shortdescription":"Buki HeadPiece","description":"Exp","rarity":"Essential","statusEffects":["nova","glow","runboost","jumpboost","lowgrav","levitation","ghostlyglow","electricblock","fireblock","poisonblock","iceblock"],"directives":"?replace;6f2919=dbecf3;e0975c=c5deee;a85636=f3f4f6;"}'

Component:
[spawn command] [item ID] [Amount] [Change Title] [New Title Name] [Change description]
[New Description] [Change Rarity] [Rarity] [statusEffect] [stats] [protection] [amount] [number] [stats] [maxHealth] [amount] [number] [stats] [powerMultiplier] [baseMultiplier] [number] [stats] [maxEnergy] [amount] [number] [Statuseffect]

[Notice: I have creating an extra section with a longer list of the status effects that you can use, guide section has a limit to how much they can fit so much. The only thing though, I had to test all of them out and it takes a long time typing out what every single does, So the description are shorter and some doesn't even have any because I couldn't figure it out, can be assumed, or too lazy. I decided to keep the ones here to show case a couple examples before being overwhilmed by all the effects]

You substitute "[Statuseffect]" with these effects below: (Note: have all the photos but putting them onto the other list instead)

--------------------------------------------------------------------------------------------------------------------------
u]DANGERS/ WARNING AND RESOLVES[/u]
This is probably one of the more fun things to add to an armor, but this is also where the game can crash if you don't type it correct. Normally, if you don't type an item correctly it will say "Could not Parse item parameters," You will crash your game if you look at the armor with an invalid Status effect. HOWEVER, I have found a way around this...
How to delete amor with invalid status effect:
Step One: Have your inventory out with the invalid object visable (Don't hover over it or it will crash).


Step Two: Normally, if you hover an object you see information about it. But if you pick up an object quickly, the game won't react quick enough to crash you.


Step Three: Drop the item into the trash and following this, quickly move the mouse away from the item. During the load of the trash, hovering over the invalid item will still crash your game. However, when you reload the game, that item will stay in the trash. Allow the item to disspear to avoid anymore risks. After that, the item is now gone.

So my plan is that there will be 3 section (when i add pictures then it should take up an extra but I have to turn all steam photos into jpg so may take a while before I do) just with status effects, how I have set this up is in this format:
[name of effect] [Does it show an icon below your character's status, notes]

[Author's Warning]
For this section of guide, I do recommend you try doing this on a different character first before sending it over to your main. On this section of the guide, I've have losted 3 charcters because I equiped the hat that contained invaild ID's, which caused a loop of crashes if loading the character. The spawn codes in this guide are valid as is, but do becareful if you want to meddle with this part.
--------------------------------------------------------------------------------------------------------------------------
Particles
EXPLANIATION:Okay, so basically particles will add an effects that doesn't give a bonus to your character, it will only create a visual change (Exp: You can recieve poison from "weakness" but it wont damage you).

HOW TO AVOID CRASHING [MUST READ IF YOU WANT TO KNOW HOW CRASHES OCCUR]
If you pay close attention, you may noticed that I used a lot of different characters for this section in the images. That is because I wasn't careful and they ended up in this Loop hole, which lead me to deleting them. Let me explain: If an item has a particle effect, then they will activily produce it (This doesn't apply to all of them, but like they pretty much all are like this). If the ID for the paricle doesn't work and the game attempts to generates the unidentified particle, then you will crash: same thing applies for status effect. If you equip an equipment with an unknown paricle ID, then you will crash in an unchangible loop. Which will result in a unusible character.

But, if you don't equip an object with an invalid particle effect, then you can still delete the item with a trick I found:

Step one: Locate the item and don't click it.

Step two: Find a chair or bed to sit on (for some reason, when you sleep or sit on something, particles don't generate).

Step three: The item can then be deleted safely.

I have decided to help make some armor for those who ask. Copy paste this Chart below and fill out what you want for your armor.

6. Value for maxHealth:

7. Value for DamageMultiplier:

Final Note
You will most likely receive a response within a couple of days or week, I am more free on the weekends. If I don't respond in 2weeks or more. Then I must not have seen your post, I do apologize.

If you are using a Mac, then some of these features might be bugged. Only I can't say for sure, because I use a pc. If you use a mac, and spawn some of these items in the game, and are having issues. Tell me what they are.

I am very hesitated to teaching how to add colors to your armor because it's very tricky. If you paid attention to the code, the only part I have not explained is the "directives":"?replace;6f2919=dbecf3;e0975c=c5deee;a85636=f3f4f6;" part, which is indeed the code that switches the color.

spawnitem cupidshead 1 '{"shortdescription":"Buki HeadBand","description":"Made By Buki","rarity":"Essential","statusEffects":[{"stat":"powerMultiplier","baseMultiplier":2.08},{"stat":"protection","amount":24},{"stat":"maxEnergy","amount":45},{"stat":"maxHealth","amount":36},"swimboost"],"effectSources":["music"],"directives":"?replace;6f2919=dbecf3;e0975c=c5deee;a85636=f3f4f6;"}'

The reason I have not taught this is because I am not quite perfect on the process I use for adding color. Also because some items run into some issues when being colored (By that I mean, I am not sure how to change some armor's color but some just doesn't appear to be textureless on some spots). Knowing what items can be colors would require me to try to test out the colors to see if they work and take too much time.
--------------------------------------------------------------------------------------------------------------------------
Basically To change the color of any equipment in the game, you must know the original untextured colors of the item, then replace the add a 6 digit code of the new one.

Problem is, I do not know any way you can possible find this untextured colors while normally playing playing starbound, sources like starcheat or "https://starbounditems.herokuapp.com/" can help, but I can not teach this without using a different program.
