Crazy Harvest – Project – Eclipse + Android SDK
Neste post demonstro o desenvolvimento de um game para Android, criado para apresentar na matéria de Programação de Jogos para Dispositivos Móveis na Pontifícia Universidade Católica do Paraná no segundo semestre de 2014.
O jogo possui algumas classes básicas para um game Android e foi criado a partir do clone do game SNAKE, conhecido entre os desenvolvedores de jogos mobile com o nome de “MrNomGame”.
O Jogo consiste em realizar toda a colheita procurando não passar duas vezes pelo mesmo local e sem estragar a colheitadeira, isso ocorre quando batemos em pedras que surgem no meio da plantação.
Para o desenvolvimento foi utilizada a IDE ECLIPSE com as devidas atualizações para java em união com a Android SDK.
Eclipse é um IDE para desenvolvimento Java, porém suporta várias outras linguagens a partir de plugins como C/C++,PHP,ColdFusion, Python, Scala e plataforma Android. Ele foi feito em Java e segue o modelo open source de desenvolvimento de software. Atualmente faz parte do kit de desenvolvimento de software recomendado para desenvolvedores Android.
Para visualizar o projeto siga os passos a seguir :
1) INSTALE O AMBIENTE DE DESENVOLVIMENTO
ECLIPSE IDE / JDK 6 OU JDL 7 (APENAS A JRE NÃO É SUFICIENTE) / ANDROID SDK
Para a instalação dos ambientes de desenvolvimento siga os passos no link abaixo
Ambientes de Desenvolvimento
2) DESCOMPACTE O ARQUIVO ZIP ABAIXO NA PASTA DE PROJETOS DO ECLIPSE
Crazy Harvest – Project – Eclipse + Android SDK.zip
3) ABRA A PASTA PELO ECLIPSE COMO PROJETO ANDROID
4) A SEGUINTE HIERARQUIA DE ARQUIVOS SERÁ DISPONIBILIZADA

5) O JOGO PODE COMPILADO E TESTADO NO PROPRIO PC
Para testar o jogo utilize o emulador da própria SDK ANDROID ou um emulador Android de terceiros.
Recomendamos o uso do software Genymotion, que pode instalar uma série de máquinas virtuais com diferentes dispositivos Android, podendo ser vinculada a IDE do ECLIPSE para testes dos aplicativos e jogos desenvolvidos.
