InputReceiver

Introduction

The InputReceiver property can be assigned to set the current IInputReceiver. The current IInputReceiver can receive keyboard input and has an ever-frame method raised for processing input. This property can be used to prevent multiple objects from receiving keyboard input. This is useful if multiple game objects respond to keyboard input - such as a a text box and a character in a platformer.

For a detailed discussion of using the InputReceiver property, see the IInputReceiver page.

Setting InputReceiver

The InputReceiver can be assigned through custom code. For example, the following might be an event executed when a button is clicked:

// assuming that "this" is the container of the click event, and that it implements the IInputReceiver interface:
FlatRedBall.Input.InputManager.InputReceiver = this;

Checking InputReceiver

The InputReciever property can be checked to see if any control is receiving input. For example, the following code runs hotkey activity if there is no InputReceiver:

if(FlatRedBall.Input.InputManager.InputReceiver == null)
{
    DoYourHotkeyImplementationHere();
}
