In GearCity, vehicles are made up of 3 components, the Chassis, the Engine, and the Gear Box. Each of these components have their own sub-components. The data for these sub-components are stored in the Components.xml file. The Components.xml file also contains the vehicle types and data, entries for vehicle artwork, and entries for accessory artwork.

The Components Editor can also edit the static popularity for AI sub-component selection. This is a separate file, but since it contains data for the sub-components, it utilizes the same Editor.

Both the Components.xml file and the ComponentsStartingPop.xml files are default game files and should not be modified directly. Use the mod system to override these files. This way you will not break your game files, won't lose your work the next time the game updates, and you can share the changes with everyone else! For more information: How to make a Mod File

To access the Components Editor, you must open the Mod Tools. See How to Open the Mod Tools if you do not know how to access the Mod Tools.

The Components Editor is available on the center column, just under “Mod Data Tools” of the Mod Tool's Main Menu. Click the button labeled “Components Editor.”

The Components Editor contains multiple sub-editors for each sub-component type in the game. As a few more editors for vehicle types, artwork, and AI. In addition to these editors there are a couple of “Global” settings such as picture files which used across all of the sub-editors.

The following picture is the upper portion of the Components Editor where you'll find the global settings for the editor, and the tabs to take you to the various sub-editors.

1. Create a new Components.xml and ComponentsStartingPop.xml files by clearing the existing data in the editor.
2. Opens an existing Components.xml and ComponentsStartingPop.xml file. Please note, you do not need to open both files at the same time. For example, if you just want to edit components.xml file, you'd click the Open Components File button, and select the Components.xml. When you're prompted to open the ComponentsStartingPop.xml file, just hit cancel. Your Components.xml file will be loaded and the AI Pop editor will be blank.
3. This will save the Components.xml file and ComponentsStartingPop.xml file. If you only wish to save one file, you may cancel the prompt for the file you do not want to save. For example, if you're only editing the ComponentsStartingPop.xml file, you would hit “Save Components/AI Pop Files”, then hit cancel when it prompts you to save Components.xml file, the next prompt will ask you to save the ComponentsStartingPop.xml file, which you would then do.
4. The takes you back to the previous editor or main menu.
5. Use this to open the folder containing all of the .dds pictures for your Sub-components, vehicle types, accessories, etc. When making a mod, these files should be put into the mod's ComponentImages.zip file, without any sub-directories. Please see How to make a Mod File for more information on how to make mods, and DDS Textures on how to make DDS textures.
6. This will tell you the current components file you are editing. If you Opened a file this will contain its file name. If you saved the file, it will tell you the save name.

This editor allows you to set the AI popularity (or AI selection preference) for component types. Each popularity value weighs toward the selection of a component based on the vehicle type they are building for. For example, if a vehicle type has a high performance importance rating. Then the components with high Performance AI Popularity values will be selected more often than ones with low Performance AI Popularity values.

The following picture shows you the parts of the editor and explains what they do.

1. This is the list of components that have AI pop values. Selecting a component from this list will load the information below.
2. This is the year which the AI popularity takes effect. The game will interpolate values between two changes.
3. This is the name and selection ID of the component. Information in this drop down is taken from the editor tabs in this image.
4. The higher this value is, the more likely this component will be chosen for vehicle types that have high fuel importance ratings.
5. The higher this value is, the more likely this component will be chosen for vehicle types that have high performance importance ratings.
6. The higher this value is, the more likely this component will be chosen for vehicle types that have high luxury importance ratings.
7. The higher this value is, the more likely this component will be chosen for vehicle types that have lower wealth demographics.
8. The higher this value is, the more likely this component will be chosen for all vehicle types.
9. This adds the popularity values to the list.
10. This removes the selected popularity value from the list.

The sub-components, vehicles types, and vehicle artwork are all handled by a single file called the components.xml file. The AI Pop files are loaded through the ComponentsStartingPopularity.xml file. For more information on the location of these files, see: File Locations

Upon creating a new save game, the game will read the components.xml and save all the data into the save game database. After which, the components.xml file will not be used for the rest of the save game's life. Thus any changes made to the components.xml file requires a new save game.

The game then reads the ComponentsStartingPop.xml files and saves that information to the database. However, unlike the components.xml file, the game will read the ComponentsStartingPop.xml at the end of every game year in order to interpolate and save new popularity values. However changes to the ComponentsStartingPop.xml file will only take effect when the year values in the entries are hit.

The following are components variables that adjust the characteristics of the specific component. The + indicates that it improves that rating or spec. The - indicates that it worsens that rating or spec.

Frames are the structure that holds together the various parts of a vehicle. As such there are certain characteristics of the frame that effect the vehicle in different ways. We'll try to describe to you the effects of each variable, however, extremely detailed data will have to wait until we write the “In-depth” wiki pages. When those pages are implemented, we'll link you there.

Suspensions are the support structures that connect the vehicle to the wheels and keep the wheels connected to the road. Certain characteristics of the suspension system effects the vehicle in different ways. We'll try to describe to you the effects of each variable, however, extremely detailed data will have to wait until we write the “In-depth” wiki pages. When those pages are implemented, we'll link you there.

Drivetrains consists of the position of the engine and the powered wheels in relation to the vehicle body. We'll try to describe to you the effects of each variable, however, extremely detailed data will have to wait until we write the “In-depth” wiki pages. When those pages are implemented, we'll link you there.

Engine Layouts are the various types of engines. They are generally described in how the cylinders are positioned in the block. We'll try to describe to you the effects of each variable, however, extremely detailed data will have to wait until we write the “In-depth” wiki pages. When those pages are implemented, we'll link you there.

Cylinders are the components that transfers the force of combustion to the crankshaft allowing the engine to generate work. We'll try to describe to you the effects of each variable in the following table, however, extremely detailed data will have to wait until we write the “In-depth” wiki pages. When those pages are implemented, we'll link you there.

Fuel is the source of the energy that is used by the engine to create combustion. The type of fuel used effects the way the engine performs. We'll try to describe to you the effects of each variable, however, extremely detailed data will have to wait until we write the “In-depth” wiki pages. When those pages are implemented, we'll link you there.

Valves are the gateways that allow air in and exhaust out of the combustion chamber of an internal combustion engine. As such they play an important role in fuel consumption, performance, and smoothness of the engine. Some engine types, such as electric, do not have a valvetrain, but for the sake of calculations they must have an entry in the valve list. The following table gives you a basic overview of the variables effect. Please see the In Depth formulas for more details.

The Induction system is the method in which air is introduced into the combustion chamber of Internal combustion engines. In most cases, the induction system will force more air into the chamber than normal atmospheric conditions would allow. As such they play an important role in fuel consumption and performance of the engine. Some engine types, such as electric, do not have a induction system, but for the sake of calculations they must have an entry in the induction list. The following table gives you a basic overview of the variables effect. Please see the In Depth formulas for more details.

The gearbox is the component which transfers and amplifies the power of the engine to the wheels. (There are a couple more parts between the wheel and gearbox of course.) The following table gives you a basic overview of the variables effect. Please see the In Depth formulas for more details.

The number of gears allows for different ratios that can be used for various purposes. The more gears you have, the broader range of benefits your engineers can get out of the gearbox by using a larger array of ratios. The following table gives you a basic overview of the variables effect. Please see the In Depth formulas for more details.

The variables for car types effect the importance of of the specific ratings for generic buyers of that vehicle type. As well effects several specs, AI decisions, and sales figures of the vehicles. In the following list, we'll give you a generic overview of what each variable does. However you should look at the in-depth explanation when the documentation for that is written.

Changes require you to start a new save game. As the Components.xml data is stored in the save game. Also if creating a mod, be sure that you have the mod selected.

If the game crashes when opening a component designer, when selecting a car body, when viewing an accessory type, or when trying to use an accessory, then you are most likely missing artwork, or did not properly zip and package your artwork correctly. Check the log files for the missing artwork, and file locations for the proper location to put these files.
