Simple Constraints
 
 
 

The simple constraints provided with reactor are Spring, Linear Dashpot, and Angular Dashpot. Unlike cooperative constraints, the simple constraint does not require you to add it to a Constraint Solver helper. Instead, reactor adds all valid simple constraints in a scene to the simulation by default. A two-bodied simple constraint is valid if it has two rigid bodies attached, while a single-bodied simple constraint is valid if it has one rigid body attached.
