Warning
This is an extension made by a community member — but not reviewed by the GDevelop extension team. As such, we can't guarantee it meets all the quality standards of official extensions.

Weld joint
- Glue two objects together
- Joint is created at the center of the Joint Connector object
Revolute joint
- Two objects are connected but can rotate on the joint
- Angles can be restricted and joints can have motors that spin the objects
- Joint is created at the center of the Joint Connector object
Distance joint
- Two objects are forced to stay at set distance from each other
- Adjust the frequency property to change the stiffness of the spring
- Center of both objects must be inside the Joint Connector collision mask
Rope joint
- Two objects can get closer to each other but they cannot exceed their starting distance
- Center of both objects must be inside the Joint Connector collision mask

Actions
Connect objects with a distance joint
Connect physics objects with a distance joint if the joint connector covers the center point of both objects.
Connect overlapping objects with a revolute joint
Connect overlapping physics objects with a revolute joint.
Connect objects with a rope joint
Connect physics objects with a rope joint if the joint connector covers the center point of both objects.
Connect overlapping objects with a weld joint
Connect overlapping physics objects with a weld joint.
Distance joint connector
Create and manage distance joints between two objects. Acts like a spring because the objects try to stay the same distance apart.
Behavior actions
Break distance joint if it exceeds breaking force
Break distance joint if it exceeds breaking force.
Set the breaking force of a joint
Set the breaking force of a joint.
Set damping ratio of joint
Set dampting ratio of joint. Range: 0 to 1.
Set frequency of joint
Set frequency of joint. Range: 0 to 60 (or the maximum FPS of game).
No expressions for this behavior.
Revolute joint connector
Create and manage revolute joints between two objects. Also known as a hinge joint because the objects act like they are connected with a hinge that pivots.
Behavior actions
Break revolute joint if it exceeds breaking force
Break revolute joint if it exceeds breaking force.
Set the breaking force of a joint
Set the breaking force of a joint.
Set clockwise angle limit of joint
Set clockwise angle limit of joint.
Set counter-clockwise angle limit of joint
Set counter-clockwise angle limit of joint.
Enable (or disable) angle limits on joint
Enable (or disable) angle limits on joint.
Enable (or disable) motor of joint
Enable (or disable) motor of joint.
Motor enabled (or disabled) on joint
Change if motor enabled (or disabled) on joint.
Set motor rotation speed of joint
Set motor rotation speed of joint.
Set motor strength of joint
Set motor strength (torque) of joint.
Behavior conditions
Motor enabled (or disabled) on joint
Check if motor enabled (or disabled) on joint.
No expressions for this behavior.
Rope joint connector
Create and manage rope joints between two objects. Objects can get closer, but they cannot exceed the starting distance from each other.
Behavior actions
Break rope joint if it exceeds breaking force
Break rope joint if it exceeds breaking force.
Breaking force
Change the force required to break joint apart.
Damping ratio
Change the damping ratio of the object. Set a number between 0 and 1.
Frequency
Change the frequency of the object. Set a number between 0 and 60. Higher numbers represent a stiffer spring.
Max distance between objects
Change the max distance between objects.
Behavior conditions
Breaking force
Compare the force required to break joint apart.
Damping ratio
Compare the damping ratio of the object. Set a number between 0 and 1.
Frequency
Compare the frequency of the object. Set a number between 0 and 60. Higher numbers represent a stiffer spring.
Max distance between objects
Compare the max distance between objects.
Behavior expressions

Return the max distance between objects. |
Weld joint connector
Create and manage weld joints between two objects. Also known as a static joint because the objects stay glued in the same relative position to each other.
Behavior actions
Break weld joint if it exceeds breaking force
Break weld joint if it exceeds breaking force.
Set the breaking force of a joint
Set the breaking force of a joint.
Set frequency of joint
Set frequency of joint. Range: 0 to 60 (or the maximum FPS of game).
No expressions for this behavior.
