Trails & Impact Effects

The ball itself is styled in the Arts tab under Ball Studio. Ball Radius sets its size, and the color controls set a solid color, a rainbow cycle, or a gradient. Add a glow to make it read as light rather than a flat dot, which is what gives runs their premium look on a dark background. On a small phone screen, a bright ball with a moderate glow is far more readable than a dark, matte one.

Trails follow the path of your balls and emphasize their motion. You can adjust the length, color, thickness, and fade of the trails to create light-painting streaks behind every ball. Long, slow-fading trails over a dark background produce the signature neon look; short trails add subtle motion blur. Trails are on by default with a length of 30, if you see none, check the toggle in the Arts tab or the Line Trail Engine add-on in the Engine tab.

When balls collide with boundaries or each other, you can trigger a visual blast. There is a large library of blast animations to choose from, so you can match the effect to your mood, explosive, celebratory, cosmic, or glitchy. You control how many particles each impact throws, how long the burst lasts, and its scale.

For the most satisfying result, coordinate your blast color with the audio. Matching the blast to the frequency or note that triggers it ties the visual payoff to the audio payoff, so each impact lands as a single audio-visual beat rather than two separate events.
