The Basics of Object Data

Introduction
The Object Editor is very simple to use. Object Data is used to make new units, abilities, spells, items, upgrades, buffs, doodads and destructables. This can also be used to edit original Blizzard made Object Data.

Creating a New Custom Object
New Object Data can be made in a click of a mouse. Either copy and paste a Blizzard Object or press Ctrl+Shift+N. Its a good idea to base the custom object on the object that is closest to the object you want to make (eg. Healing Item -> potion of healing, a basic soldier -> Footman).

Units
Units are probably the most common object data made. This part of the tutorial will explain the basics of making units and buildings.

Making a Hero
Select a Blizzard made hero that is closest to the hero you plan to make. When it is made you can change abilities, model, icons, ect. Turning it into a unit is quite simply as well, you just have to copy and paste the units object data. However some object Data will have to be made up (eg, proper names, strength, agility, intelligence, ect).

Editing Object Data
This is a list of all the categories and where you can expect to find things.

• Text
  This is where you will find names, tool tips, hotkeys and descriptions. This is something that should definitely be changed for custom units/heros.
  
• Abilities
  Pretty obvious, this is where you can change the units/heros abilities.
  
• Pathing
  Although this will mostly only be changed for buildings the collision size can be changed for units/heros.
  
• Movement
  Change the speed of your unit/hero. This is also where you can set the unit/hero to be air, ground or water unit.
  
• Techtree
  Change/make requirements for the unit/hero/building. For buildings it can also decide what units, upgrades, items are made/sold.
  
• Stats
  Change the health, mana, agility, strength, intelligence, level, gold cost, lumber cost, ect. the race, transport size, unit classifacation.
  
• Editor
  This is nothing that really needs to be changed. Enabling the click helper sometimes eases working with tiny units in the editor though.
  
• Sound
  Change the soundset to the different units / heros.
  
• Art
  Can change the model file, icon, color, size, ect.
  
• Combat
  Changes damage, projectile, targets, ect.
  
  
• Items
  The categories are the same as units except with different values. But the basic things are still there, model file, icon, ability, ect.
  
• Destructables
  Destructables are where trees, gates, bridges, and some walls are made. These can either be walked on like bridges, or targeted like gates, walls and barricades. This is where there are also Pathing Blockers, these are used to block of certain areas. When placed a small pink and black checkered box will appear. These will be invisible in game. Once again the categories are the same as units except there's one major difference. Instead of changing the size being in art it is in editor, named as Maximum Scale, Minimum Scale.
  
• Doodads
  Doodads are almost exactly the same as destructables except none of these can be targeted or selected. Doodads are basically terrain.
  
• Abilities
  Now abilities get a bit more complicated here. This is used to make the abilities for both units and items. In the stats we will see a Hero Ability and an Item Ability. If it's an item ability tick Item Ability. If its a hero ability click Hero Ability, and if its a unit ability have both unticked. Blizzard item abilities are under Special-Items. Abilities can be assigned to units/heros/items through the ability category in the units and items sections.
  
• Buffs
  Buffs/Effects are used by abilities the same way abilities are used by units and items. A buff can be selected for an ability in the ability section.
  
• Upgrades
  Upgrades can be used in a number of ways. They can be used as requirements for units and buildings, they can be used to give units and heros extra damage, defence, armor, strength, intelligence, agility, ect.

Conclusion
The conclusion is that Object Data is really simple. If you have any questions pm me or another moderator.

A very good tutorial for beginners - Accepted.

I had to fix a bunch of spelling errors though, please take care next time.
But nonetheless, well done.
I'll check your other tutorial tomorrow.

- moved to beinners tutorials

Ok... This is a really nice tutorial. However, I have a tiny suggestion, considering that this is for beginners. Maybe you should also mention the fact that not all fields do something. For example, Evasion's AoE fields do not turn the spell into an aura or affect only units within the AoE mentioned in the field. This would avoid a lot of confusions. I gave you this example because I myself had this problem, with this exact example. I was certain that giving Evasion an AoE would make it work for all units around the caster.Obviously I was wrong.

im new but i wan to ask... how to increase max level of hero

Advanced -> Gameplay Constants. Check "Use Custom Gameplay Constants".
Find B) Hero Maximum Level, and double click to edit the value.

Err, I think that your post is unrelated, so please try searching first before asking (or ask in another section).

Anyway, nice tutorial for beginners, and I agree with Daelin.

THX alot

How to put the ability to the hero?

Find the desired Hero in the object editor -> double click on Abilities Hero and then manage your skills by adding, removing or swaping them with others

I have a question. I downloaded some models from this site, but they are all in .mdx format. But when i wanna use them, the object editor wants .mdl formats. I cannot use either of them. Any help?

Import them and use them as if they were .mdls. The World Editor converts them automatically.

No it doesn't. It says model not found or something. But when importing it, i have no problem. The file description says it is model and such, just the unit shows as green and black chessy box.

Which model specifically?

Greteengs.

I have the question. I want create a big unit. The tank which is two times bigger then normal, as example. But here I got a problem with it's physical size. Every unit is walking through my tank and I can't fix it. I have tried almost everything in Object Editor but it still doesn't work properly.

Help me please.

I need add that at this time I have not english version of Warcraft with translation which could be better.
