Game Development

Finally getting back to production code… and to the missing test case from four episodes ago. TDD doesn’t replace thinking! Hope I got it right this time. ► All Game of Life Episodes: http://goo.gl/xc59GX ► Let’s Develop! http://letsdeveloper.com ► Don’t Miss an Episode: http://goo.gl/whzDi1 «Conway’s Game of Life» The Game […]

Conway’s Game of Life #20 – Game Loop – Limiting ...

4 Apr, 2015 in Conway's Game of Life / Let's Develop tagged Game Development / TDD by letsdeveloper

Mocking is a little ugly with generics, since we need to suppress some warnings. Using Mockito’s JUnit runner is a beautiful alternative way to create (and inject) mocks without these warnings! Definitely worth to know. ► All Game of Life Episodes: http://goo.gl/xc59GX ► Let’s Develop! http://letsdeveloper.com ► Don’t Miss an […]

Conway’s Game of Life #19 – Game Loop – Mockito ...

We’re still refactoring out tests. This one got a special challenge: testing the order of call (you might remember: update must be called before render, to avoid lags). Mockito can check order, if you know how to tell it! ► All Game of Life Episodes: http://goo.gl/xc59GX ► Let’s Develop! http://letsdeveloper.com […]

Conway’s Game of Life #18 – Game Loop – Mockito ...

Our tests are redundant and ugly, because there’s lot’s of boilerplate code for the stubbing. Let’s see if we can clean this up using a mocking framework. Not because it can do something we can’t, but because creating the stubs is less verbose and more flexible. ► All Game of […]

Conway’s Game of Life #17 – Game Loop – Mockito

Now for making our game loop catch up, if execution is delayed by other processes or a lazy CPU. A simple second test for our loop and we’re done. Right? Hell no, but I didn’t realize until much later… ► All Game of Life Episodes: http://goo.gl/xc59GX ► Let’s Develop! http://letsdeveloper.com […]

Conway’s Game of Life #16 – Game Loop – Framelimit ...

Having clean tests, we can introduce the means to test timing behaviour in our game loop. It is important to introduce proper abstractions in order to write robust tests that control time. It’s conceptually easy, but often done wrong in practice. ► All Game of Life Episodes: http://goo.gl/xc59GX ► Let’s […]

We rushed along and accumulated some technical dept in our test suite. For the next feature I intend to implement, this is going to hurt us! So first thing to do is clean up the tests. ► All Game of Life Episodes: http://goo.gl/xc59GX ► Let’s Develop! http://letsdeveloper.com ► Don’t Miss […]

Let’s make our game loop interactive! Without user input any game is boring, right? So we need respective handling in the loop. Int his episode I’m test-driving it into our code. ► All Game of Life Episodes: http://goo.gl/xc59GX ► Let’s Develop! http://letsdeveloper.com ► Don’t Miss an Episode: http://goo.gl/whzDi1 ► Test-Driving […]

Conway’s Game of Life #13 – Game Loop – Input

27 Mar, 2015 in Conway's Game of Life / Let's Develop tagged Game Development / TDD by letsdeveloper

Third step: We want the loop to render the game. This has to happen after the update, otherwise the game might lag. Order is easy to ensure with handcrafted stubs! ► All Game of Life Episodes: http://goo.gl/xc59GX ► Let’s Develop! http://letsdeveloper.com ► Don’t Miss an Episode: http://goo.gl/whzDi1 ► Test-Driving the […]
