Eight days since my last post and the backglass is finally getting close to being done. Working with bleeding edge mpf has been slow and frustrating and I am very much looking forward to getting back to making saw dust and solder smoke. I have literally spent days getting to this point.
Currently the backglass has 20 second cut scenes of each of the 10 bosses with a 3 second animation between them. The display is divided into a static topper, middle video section and lower scoring section. I've gone through multiple versions before deciding on the current one. In game play the full length videos of the 10 bosses are played at random with the theme song for each boss matched up to the video.
There are many animations and scenes that play during the game including, CUP/MUG drop targets and the 10 soul contracts that are collected for clearing the banks, SOUL top lanes, Dash saucers, Knockout, Perdition entry x 3 and more.
The latest addition was that as of yesterday the dev version of mpf now supports "digital_score_reels" which are zip files with a png animation sequence of a score reel with transitions between digits. At present the system will advance a "nines rollover" as soon as the points are scored so that looks a little funny (score 50 points and it goes 00180, 00290, 00200, 00210, 00220 not 00180, 00190, 00200, 00210, 00220) but all in all getting this to work has taken a ton of time and looks pretty awesome.
