kDefaultSheetSpring top-level constant
SpringDescription
const kDefaultSheetSpring
The default SpringDescription used by SheetPhysics subclasses.
This spring has the same configuration as the resulting spring
from the SpringDescription.withDampingRatio constructor with
a ratio of 1.1
, a mass of 0.5
, and a stiffness of 100.0
.
Implementation
const kDefaultSheetSpring = SpringDescription(
mass: 0.5,
stiffness: 100.0,
// Use a pre-calculated value to define the spring as a const variable.
// See the implementation of withDampingRatio() for the formula.
damping: 15.5563491861, // 1.1 * 2.0 * sqrt(0.5 * 100.0)
);
