Detailed Description

This component polls all input events from the given input set every frame and broadcasts the information to components on the same game object.

To deactivate input handling, just deactivate the entire component. To use the input data, add a message handler on another component and handle messages of type ezTriggerMessage. For every input event, one such message is sent every frame. The granularity property defines for which input events (key pressed, released or down) messages are sent.

Member Function Documentation

◆ DeserializeComponent()

void ezInputComponent::DeserializeComponent ( ezWorldReader stream)
overridevirtual

Override this to load the current state of the component from the given stream.

The active state will be automatically serialized. The 'initialized' state is not serialized, all components will be initialized after creation, even if they were already in an initialized state when they were serialized.

Reimplemented from ezComponent.
