Overridden from UInteractiveToolActivity
| Type | Name | Description | |
|---|---|---|---|
   |
bool | CanAccept () |
If true, calling End with EToolShutdownType::Accept will result in a valid completion of the activity. |
   |
bool | CanStart () |
Check whether a Start() call will result in a success. |
  |
EToolActivityEndResult | End
(
EToolShutdownType |
Force an end to the activity. |
   |
bool | HasAccept () |
Similar to a tool, this determines whether the activity prefers an accept/cancel option to be displayed (if true) vs a "complete". |
   |
bool | IsRunning () |
Check whether the activity is running (though the tool can just check the result of Start() itself). |
  |
void | Shutdown
(
EToolShutdownType ShutdownType |
Should be called during a tool's Shutdown() |
  |
EToolActivityStartResult | Start () |
Attempt to start the activity. |

  |
void | Render
(
IToolsContextRenderAPI* RenderAPI |
If the activity is running, should be called from the tool's Render() |
  |
void | Setup
(
UInteractiveTool* ParentTool |
IInteractiveToolActivity. |
  |
void | Tick
(
float DeltaTime |
If the activity is running, should be called from the tool's OnTick() |

Overridden from IHoverBehaviorTarget
| Type | Name | Description | |
|---|---|---|---|
  |
FInputRayHit | BeginHoverSequenceHitTest
(
const FInputDeviceRay& PressPos |
IHoverBehaviorTarget implementation. |
  |
void | OnBeginHover
(
const FInputDeviceRay& DevicePos |
