# OnEvaluate
|
||
|
||
- **使用位置：** UPROPERTY
|
||
- **引擎模块：** AnimationGraph
|
||
|
||
## 原理：
|
||
|
||
在源码中发现，说明OnEvaluate已经放弃了。
|
||
|
||
```cpp
|
||
// Dynamic value that needs to be wired up and evaluated each frame
|
||
const FString& EvaluationHandlerStr = SourcePinProperty->GetMetaData(AnimGraphDefaultSchema->NAME_OnEvaluate);
|
||
FName EvaluationHandlerName(*EvaluationHandlerStr);
|
||
if (EvaluationHandlerName != NAME_None)
|
||
{
|
||
// warn that NAME_OnEvaluate is deprecated:
|
||
InCompilationContext.GetMessageLog().Warning(*LOCTEXT("OnEvaluateDeprecated", "OnEvaluate meta data is deprecated, found on @@").ToString(), SourcePinProperty);
|
||
}
|
||
```
