Brief Description

Damped spring constraint for 2D physics.


Damped spring constraint for 2D physics. This resembles a spring joint that always wants to go back to a given length.

Property Descriptions

Setter set_damping(value)
Getter get_damping()

The spring joint’s damping ratio. A value between 0 and 1. When the two bodies move into different directions the system tries to align them to the spring axis again. A high damping value forces the attached bodies to align faster. Default value: 1

Setter set_length(value)
Getter get_length()

The spring joint’s maximum length. The two attached bodies cannot stretch it past this value. Default value: 50

Setter set_rest_length(value)
Getter get_rest_length()

When the bodies attached to the spring joint move they stretch or squash it. The joint always tries to resize towards this length. Default value: 0

Setter set_stiffness(value)
Getter get_stiffness()

The higher the value, the less the bodies attached to the joint will deform it. The joint applies an opposing force to the bodies, the product of the stiffness multiplied by the size difference from its resting length. Default value: 20
