Various events are called by the animation system to initialize and update the Animation Blueprint. These can be placed in the Event Graph to implement or override functionality.
Blueprint Initialize Animation
The Blueprint Initialize Animation event is executed once when the Animation Blueprint instance is created to perform initialization operations.
| Pin | Description |
|---|---|
| Output Pins | |
| Exec (Blank) | Fired once each frame when the BlueprintInitializeAnimation() event is executed in code. |
Blueprint Update Animation
The Blueprint Update Animation event is executed every frame allowing the Animation Blueprint to perform calculations and updates to any values it needs. This event is the entry point into the update loop of the EventGraph. The amount of time elapsed since the last update is available from the DeltaTimeX pin so time-dependent interpolations or incremental updates can be performed.
| Pin | Description |
|---|---|
| Output Pins | |
| Exec (Blank) | Fired once each frame when the BlueprintUpdateAnimation() event is executed in code. |
| Delta Time X | Outputs the amount of time since the last execution cycle. |
