Duvida Plese Help

Ola pessoal descupe encomoda mais alguem pode dizer como coloco no meu script ai 
Codigo de gasolina e de leva dano quando colidir demais ????

Vc tem que criar um javascript na aba project, clique com o botão direito do mouse>new>javascript... ai vc abre, provavelmente vai abrir o monodevelop ai vc copia e cola seu script la.

Java cara, por que java? Por que trabalha com java? Tem tutorial sobre dano e tudo mais no canal, mas na linguagem top padrão, que é C#
