Using AssetsManager

The AssetsManager is the core component in effective media management inside your Gorilla3D application.

Models, textures, audio and so on will be cached for faster access and reusage. You can build packages within the AssetsManager for modular media management.

For example: you could build a package for the main character and reference to it in every scene package. Scene packages are extremly useful for compact and fast loading of all data of a specific scene.

An assets package is the management unit to handle groups and their attached assets. It is allowed to store a package as zip-archive or to use as in-memory package.

Each package provides a number of fixed group entries to organize media content.

• GORILLA_ASSETS_MODEL
• GORILLA_ASSETS_TEXTURE
• GORILLA_ASSETS_AUDIO
• GORILLA_ASSETS_VIDEO
• GORILLA_ASSETS_MISC
• GORILLA_ASSETS_DIALOGUE
• GORILLA_ASSETS_INVENTORY

A media file is represented as extended TGorillaAsset instance inside in a specific group in an assets package. Depending on the media type the asset holds the data.

Holds model and animation data by the internal definition format TModelDef and writes data as *.g3d file to the zip-archive.

Holds the texture as TBitmap in memory and writes those in original file format to zip-archive.

Holds audio files in a TMemoryStream and writes those in original file format to zip-archive.

Holds video files in a TMemoryStream and writes those in original file format to zip-archive.

Used for unspecified file formats. Currently supported *.txt, *.json and *.xml. Holds data in a TMemoryStream and writes those in original file format to zip-archive.

Holds dialogue data in a TMemoryStream and writes those as *.dia file to zip-archive.

Holds inventory configuration data in a TMemoryStream and writes those as *.iff file to zip-archive.

You can find the TGorillaAssetsManager component in the toolbar. Simply drag and drop onto your form.

In the next step we need to create a new package in “Packages” property by the Delphi collection editor.

Alternatively you can create the assets manager and packages at runtime.

Form1.pas

  FAssetsManager := TGorillaAssetsManager.Create(Self);
  FAssetsManager.AddEmptyPackage(GORILLA_PACKAGE_DEFAULT);
