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

<methods>
<method name="get_damping" qualifiers="const">
<return type="float">
</return>
<description>
Return the damping ratio of the spring joint. A value of 0 indicates an undamped spring, while 1 causes the system to reach equilibrium as fast as possible (critical damping).
</description>
</method>
<method name="get_length" qualifiers="const">
<return type="float">
</return>
<description>
Return the maximum length of the spring joint.
</description>
</method>
<method name="get_rest_length" qualifiers="const">
<return type="float">
</return>
<description>
Return the resting length of the spring joint. The joint will always try to go to back this length when pulled apart.
</description>
</method>
<method name="get_stiffness" qualifiers="const">
<return type="float">
</return>
<description>
Return the stiffness of the spring joint. The joint applies a force equal to the stiffness times the distance from its resting length.
</description>
</method>
<method name="set_damping">
<return type="void">
</return>
<argument index="0" name="damping" type="float">
</argument>
<description>
Set the damping ratio of the spring joint. A value of 0 indicates an undamped spring, while 1 causes the system to reach equilibrium as fast as possible (critical damping).
</description>
</method>
<method name="set_length">
<return type="void">
</return>
<argument index="0" name="length" type="float">
</argument>
<description>
Set the maximum length of the spring joint.
</description>
</method>
<method name="set_rest_length">
<return type="void">
</return>
<argument index="0" name="rest_length" type="float">
</argument>
<description>
Set the resting length of the spring joint. The joint will always try to go to back this length when pulled apart.
</description>
</method>
<method name="set_stiffness">
<return type="void">

<argument index="0" name="stiffness" type="float">

Set the stiffness of the spring joint. The joint applies a force equal to the stiffness times the distance from its resting length.
