libgdx multiple objects implementing InputProcessor

Question

So on my Screen I have two objects of the same class that implement InputProcessor with the following keyDown() method:

Answer 1

Here is a code sample on LibGDX.info showing how to implement multiplexing with LibGDX:

I hope it helps

Answer 2

You need to use an InputMultiplexer to forward the events to both InputProcessors. It will look like this:

InputProcessor inputProcessorOne = new CustomInputProcessorOne();
InputProcessor inputProcessorTwo = new CustomInputProcessorTwo();
InputMultiplexer inputMultiplexer = new InputMultiplexer();
inputMultiplexer.addProcessor(inputProcessorOne);
inputMultiplexer.addProcessor(inputProcessorTwo);
Gdx.input.setInputProcessor(inputMultiplexer);

The multiplexer works like some kind of switch/hub. It receives the events from LibGDX and then deletegates them to both processors. In case the first processor returns true in his implementation, it means that the event was completely handled and it won't be forwarded to the second processor anymore. So in case you always want both processors to receive the events, you need to return false.
