Doodle jump онлайн на HTML5

Doodle jump онлайн на HTML5

28.08.201227215

Открытый исходный код, копируйте, и на вашем сайте будет Doodle jump онлайн на HTML5. Если HTML5 не поддерживается, то будет выведено сообщение. Игра очень популярная, в нее играют не только на переменах в школе, можно играть и на компьютере, онлайн. Автор данного кода Kushagra Agarwal, перевод и звуки добавил Denis Abdullin.

Я добавил звуки, а то без них скучновато. Т.е. автор сделал изначально без звуков, пришлось покопаться в игре и коде, чтобы добавить этот «пук-пук» и звук пружинки, и хотя бы звук падения.

не знаю баг или нет, но если на месте прыгать он очки все равно плюсует)

Естественно баг!

Есть ещё баг. На 3-4 дудлера. Смотри, в начале перед тем как нажать play, разогнись до такого состояния, чтобы дудлера было 3-4. И потом так таким и останешься. Плюс в том, что когда прыгаешь ты можешь отталкиваться сразу 3-4 дудлерами. Так на много легче :)
