2D maze game with device orientation - Game development
ional features. we can for example add power-ups to collect along the way that will make our ball roll faster, stop the timer for a few seconds or give the ball special powers to go through obstacles. there’s also room for the traps which will slow the ball down or make it more difficult to reach the hole. you can create more levels of increasing difficulty. you can even implement achievements, leaderboards and medals for different actions in the game. there are endless possibilities — they only depend on your imagination. summary i hope this tutorial will help you dive into 2d game development and inspire you to create awesome games on your own. you can play the demo game cyber orb and check out its source code on github. html5 gives us raw tools, the frameworks built on top of it are ge...

Web Locks API - Web APIs
he use of resources. web locks concepts and usage a lock is an abstract concept representing some potentially shared resource, identified by a name chosen by the web app. for example, if a web app running in multiple tabs wants to ensure that only one tab is syncing data between the network and indexed db, each tab could try to acquire a "my_net_db_sync" lock, but only one tab will succeed (the leader election pattern.) the api is used as follows: the lock is requested. work is done while holding the lock in an asynchronous task. the lock is automatically released when the task completes. navigator.locks.request('my_resource', async lock => { // the lock has been acquired. await do_something(); await do_something_else(); // now the lock will be released. }); while a lock is h...
