UnderwareDESIGN

    Flappy bird was one of those break out hits that come along every now again and captivate the public.  What makes it interesting today (for us) it is feels a lot like  the types of video games people made way back in the early days of computer games, with simple visuals but brutally honest game play, where the player lives or dies by the pixel. 

    For this challenge we'll just focus on the players movement.   So stripping away everything  but the main character,  you need to construct a similar style of character movement where the player moves not necessarily in straight lines, but an arc of some type and  with the least amount of controls possible.  To make it more stimulating you can add objects to the scene that player needs to navigate to reach a goal.    You don't need any artwork, just use a circles / lines / box for the main display or some of the existing stock art that's on the boards or in the help files.

    So for those that take this challenge on, you'll learn many fundamentals ranging from  input controls / sinus / projectile motion / computer animation & collision if add obstacles.  All of which will translate into your everyday BASIC programming skills.     

     Good luck !


     As always we'll award   Extra Brownie points to the most creative submissions .

I made as small a version as i could.

I would prob be able to shave more code by checking coordinates rather than the sprite method.

I await my $50000 a day

Hello monkeybot!

Just a few rows of code, but nevertheless so funny!  :D
Well, I would give you my vote!

Regards,

Sigtrygg

I've never played in Flappy Bird, but i see it in youtube.
It's my version.

 That's looks pretty much like Flappy Bird styled movement to me.   So you can both have a shiny virtual star for your collections!     ;D

Thanks Kevin!

Wohoo fame at last.

This is a cut'n'paste version of the ATLUS's example with a few clean ups.

Thanks, why so slow?

runs the same here, given it's 99.9999% the same code..

Ok, i'll try test it again in home.
