# Obsolete Members for Qt3DLogic

The following members of class Qt3DLogic are deprecated. They are provided to keep old source code working. We strongly advise against using them in new code.

## Namespaces

`(deprecated)` namespace | Logic

## Classes

`(deprecated)` class | QFrameAction
`(deprecated)` class | QLogicAspect

## Namespaces

### `[deprecated]` namespace Qt3DLogic::Logic

This namespace is deprecated. We strongly advise against using it in new code.

## Classes

### `[deprecated]` class Qt3DLogic::QFrameAction

This class is deprecated. We strongly advise against using it in new code.

The QFrameAction provides a way to perform tasks each frame in a synchronized way with the Qt3D backend. This is useful to implement some aspects of application logic and to prototype functionality that can later be folded into an additional Qt3D aspect.

For example, the QFrameAction can be used to animate a property in sync with the Qt3D engine where a Qt Quick animation element is not perfectly synchronized and may lead to stutters in some cases.

To execute your own code each frame connect to the QFrameAction::triggered signal.

### `[deprecated]` class Qt3DLogic::QLogicAspect

This class is deprecated. We strongly advise against using it in new code.
