Дипломная (вкр): Розробка ігрової програми для мобільних пристроїв з сенсорним екраном

5.3 Отримані результати

Програма розроблялася в інтегрованому сереловищі NetBeans IDE 7.0. [6]

В одержаній реалізації, гра матиме такий вигляд.

Скріншот зроблено у програмі MicroEmulator 2.0.4.62.

Дана версія розрахована на дисплеї з роздільною здатністю 640х360 пікселів. Програма тестувалась на телефоні Sony Ericsson U1, де успішно працювала.

Висновки

В ході виконання роботи було запропоновано реалізацію гри, для мобільних пристроїв з сенсорним екраном на базі обраної платформи Java Micro Edition. Отримано досвід роботи з інструментами розробки програм для мобільних пристроїв, зокрема в середовищі NetBeans IDE 7.0.

Важливими особливостями такого програмування є розміри графічних елементів інтерфейсу - адже це значним чином впливає на зручність користування продуктом. При цьому потрібно враховувати роздільну здатність екрану і точність сенсору, а також користуватиметься людина стилусом, чи пальцем. Можливий варіант виходу з ситуації - розробка різних версій продукту для пристроїв з кардинально різними характеристиками. Завдяки універсальності платформи Java ME цей процес зводиться до заміни графічних файлів і констант, а не повного переписування коду.

Варто зазначити, що розробка ігрових програм для портативних пристроїв - доволі перспективна сфера, адже кількість мобільних телефонів з сенсорним екраном постійно зростає, а людству ніколи не набридне грати в цікаві ігри, що зумовлює попит на відповідне програмне забезпечення.
