Joystick - Android

Olá, baixei um asset free na asset store de um player2d que já vem com os movimentos configurados para o pc/joystick, queria criar um joystick virtual que simulasse as teclas do teclado. Dei uma olhada nos tutoriais disponíveis e não consegui achar nada para um jogo 2D. 

O player depende apenas de 6  teclas para funcionamento, eis a minha duvida: exite algum jeito de fazer com que um botão UI realize a mesma função da letra A? Digo não que ao clicar no botão ele entenda que é pra executar um daqueles Axis do Input, mas sim fazendo com que o jogo acredite que a tecla que foi apertada foi a do teclado. Por exemplo:

Se o UI Button for pressionado, esta ação é igual a pressionar a tecla A do teclado. 

Como se fosse um botão de atalho, você pode clicar neste botão do teclado para realizar a ação, mas tbm pode clicar no botão UI para a mesma função   

Ficou um pouco confuso, espero que entendam.

Alguém sabe se o que está comentando neste forum funciona?

Depende do que você está tentando fazer... você pode mudar todos os inputs da Unity manualmente em Edit>ProjectSettings>Input

Mas pelo que eu entendi, basta criar um botão que chama uma void, e o input da letra chamar a mesma void...

Esse é o meu problema, se o Input chamasse uma função seria tranquilo, o problema que o código de movimentação não utiliza só uma função. 

Notei que o que depende do Input é a float hor, tentei criar uma função que igualasse a float hor positiva (1) ou negativa (-1), porém não funcionou.

Segue código que estou tentando fazer essa troca de botões do teclado para Botões UI:
