See SetParam documentation for descriptions of duplicate parameters.

Parameters
[in]_keyString key Below is a list of _key parameter definitions:
  1. "solver_type" (string) - returns solver used by engine, e.g. "sequential_impulse' for Bullet, "quick" for ODE "Featherstone and Lemkes" for DART and "Spatial Algebra and Elastic Foundation" for Simbody. -# "type" (string) - deprecated, use keyword "solver_type". -# "cfm" (double) - global CFM -# "erp" (double) - global ERP -# "precon_iters" (bool) - precondition iterations (experimental).
  2. "iters" (int) - number of LCP PGS iterations. If sor_lcp_tolerance is negative, full iteration count is executed. Otherwise, PGS may stop iteration early if sor_lcp_tolerance is satisfied by the total RMS residual.
  3. "sor" (double) - relaxation parameter for Projected Gauss-Seidel (PGS) updates.
  4. "contact_max_correcting_vel" (double) - truncates correction impulses from ERP by this value.
  5. "contact_surface_layer" (double) - ERP is 0 for interpenetration depths below this value.
  6. "max_contacts" (int) - max number of contact constraints between any pair of collision bodies.
  7. "min_step_size" (double) - minimum internal step size. (defined but not used in ode).
  8. "max_step_size" (double) - maximum physics step size when physics update step must return.
[in]_valueThe value to set to
Returns
true if SetParam is successful, false if operation fails.
