Quick guide to start modding Dinogen Online.

Anyone can start modding Dinogen Online! Make sure you have the latest version of the game installed.

Navigate to the game assets directory. You can right-click Dinogen Online in your Steam library and click Manage > Browse local files.

The default directory is:

<STEAM PATH>\steamapps\common\Dinogen Online

Game assets are located in the assets directory.


Audio files are stored in the sounds directory.

Audio files must be in MP3 format.

Graphics & Animations

All graphics and animations are located in the images directory.

Download the latest Modding Tools from https://dinogenonline.com/resources.

You will need Adobe Animate to open .fla files.


  • Open the desired file in Adobe Animate
  • Select all required Movieclips
  • Right click > Generate Sprite Sheet…

In the Generate Sprite Sheet dialog, use the following settings:

  • Image dimensions: <Auto size>
  • Image format: <PNG 32 bit>
  • Background color: <transparent>
  • Algorithm: <MaxRects>
  • Data format: <JSON>
  • <Trim> and <Stack frames> enabled
  • Border padding: 0px
  • Shape padding: 1px

Browse to the applicable file in the assets/images directory and click Export.


If you encounter any visual problems after using exported files, make sure you included
all required files before generating sprite sheet. You can verify by comparing the
unmodified game files.

Game Engine (Phaser CE)

Phaser CE is the underlying HTML5 game engine. You can modify it in the assets/lib/phaser directory.

This can useful in improving performance or adding effects.

New Files

If you want to load new files into the game (rather than modifying existing ones), add them to preload.json.

Note that preload.json only supports audio files at this time.

Specify the typeid, and path in preload.json:

    "type": "audio", 
    "id": "customVoiceClip", 
    "path": "customCampaign/customVoiceClip.mp3" 

Assets referenced to preload.json are stored in the assets/custom directory. In the above example, customVoiceClip would be located in assets/custom/customCampaign/customVoiceClip.mp3 and referenced to as customVoiceClip in game.


You can reference these custom files in custom scenarios, such as adding new voice clips for NPCs and mission objectives.

Sharing and Installing Mods

Installing Mods

After downloading the mod zip, simply extract the contents to the Dinogen Online assets directory. The modded files will overwrite the existing game files.

Removing Mods

If you want to remove/uninstall a mod, simply right-click Dinogen Online in your Steam library > Properties > Local Files > Verify integrity of game files. This will reinstall the original game files.
