The beautiful thing about digital pinball is it’s low cost entry to maximum fun.

Original pinball titles doing things only possible in the digital realm have swelled in number, with one company having over 70 titles that also offer full cabinet support. Various companies make digital pinball cabinets, with working DMD screens, digital backboxes, working solenoids, shaker motors, and tilt bobs to seriously blur the line between real and digital. Not too many locations in the world that can boast that number, and these won’t ever be down for maintenance. There are as of this writing 144 real world tables you can play recreations of either on your iPhone or PC, fully licensed by the original manufacturers. What digital pinball does offer is a valid alternative. Don’t get me wrong, I love real pinball and am not here to convince you digital is better. My name is Chris, and I am a digital pinball junkie.

We could finesse this calculation further to create a more accurate effect, but we’ll keep it simple for this sample. We work out what direction the ball is travelling in and then rotate either left or right by a quarter of a turn until the ball no longer collides with a wall. If you wanted more realistic physics, you’d calculate the reflection angle from the surface which has been hit, but in this case, we’re going to use a shortcut which will produce a rough approximation.

To get it working on your system, you’ll need to install Pygame Zero. If it has, we need to make the ball bounce. We need to detect collisions with objects and obstacles, so we sample four pixels around the ball to see if it’s hit anything solid. Our new x-coordinate will move by the sin of the ball direction multiplied by the speed, and the new y-coordinate will move by the cos of the ball direction multiplied by speed. With these values set, the ball can be moved using a bit of trigonometry. Defining the ball as an Actor, we can add a direction and a speed parameter to it. With these elements in place, we have our play area and an ability for the player to defend the exit.Īll we need now is a ball to go bouncing around the obstacles we’ve made. If no key is pressed, then the flipper drops back down. We detect left and right key presses and rotate the angle of the flippers by 20 degrees within a range of -30 to +30 degrees. These are defined as Actors with a pivot anchor position set near the larger end, and are positioned near the bottom of the play area. Here it is: your own pinball game in less than 100 lines of code.
