Tryll Engine

Unreal C++ API Reference

Unreal C++ API Reference¶

Full API reference for the TryllClient Unreal Engine plugin, auto-generated from Doxygen documentation blocks in server/client-unreal/Source/TryllClient/Public/. Browse individual classes and structs in the sidebar.

Entry points¶

Type	Role
`UTryllSubsystem`	`UGameInstanceSubsystem` — connect, configure, manage models and storages
`UTryllWorkflowAsset`	`UDataAsset` — editor-authored graph; assign to an agent component
`FTryllAgent`	Agent handle returned by `UTryllSubsystem::CreateAgent`

Graph types¶

Type	Role
`FTryllGraphDescription`	Complete graph: nodes, routes, start id
`FTryllGraphBuilder`	Fluent builder for `FTryllGraphDescription`
`FTryllNodeDescription`	Single node definition
`FTryllNodeParam`	Key/value string parameter on a node
`FTryllExitRoute`	Single exit-route wire

Supporting types¶

Type	Role
`FTryllError`	Error envelope — `ETryllErrorCode` + message string
`FTryllModelInfo`	Model catalog row returned by `ListModels`
`FTryllToolDefinition`	Tool declaration
`FTryllToolParamDefinition`	Single parameter within a `FTryllToolDefinition`
`UTryllSubsystem::FEmbeddedStorageInfo`	Embedded-storage descriptor

Headers¶

Header	Declares
`TryllSubsystem.h`	`UTryllSubsystem`, `FEmbeddedStorageInfo`
`TryllAgent.h`	`FTryllAgent`
`TryllAgentComponent.h`	`UTryllAgentComponent`
`TryllWorkflowAsset.h`	`UTryllWorkflowAsset`
`TryllGraphDescription.h`	`FTryllGraphDescription`, `FTryllGraphBuilder`, node/route types
`TryllModelInfo.h`	`FTryllModelInfo`, `ETryllModelStatus`
`TryllError.h`	`FTryllError`, `ETryllErrorCode`

Selected method signatures¶

`UTryllSubsystem::ConfigureSession`¶

UFUNCTION(BlueprintCallable, Category = "Tryll|Session")
void ConfigureSession(
    ETryllInferenceEngine Engine,
    bool                  bAllowAutoModelDownloading = false);

When bAllowAutoModelDownloading is true, subsequent CreateAgent calls download missing models automatically. The setting is also available in Project Settings → Plugins → Tryll Client (UTryllRuntimeSettings::bAllowAutoModelDownloading). See Enable Auto Model Downloading.

Note

UTryllAgentComponent is Blueprint-accessible but not listed separately in the sidebar since all its Blueprint nodes are catalogued in the Blueprint Catalog.
