C++ (Cpp) cpConstraintGetUserData Examples

Example #1

File: ofxChipmunkSpring.cpp Project: underdoeg/ofxChipmunk

cpFloat Spring::springForceFunc(cpConstraint *constraint, cpFloat dist){
	Spring* spring = (Spring*)cpConstraintGetUserData(constraint);
	if(spring->forceFunction){
		return spring->forceFunction(spring, dist);
	}
	return 0;
}

Example #2

File: cp_constraint.c Project: afaur/mruby-chipmunk2d

mrb_value
mrb_cp_constraint_get_mrb_obj(mrb_state *mrb, const cpConstraint *constraint)
{
  struct mrb_cp_constraint_user_data *user_data;
  user_data = cpConstraintGetUserData(constraint);
  if (user_data) {
    return user_data->constraint;
  } else {
    return mrb_nil_value();
  }
}

Example #3

File: cp_constraint.c Project: afaur/mruby-chipmunk2d

void
mrb_cp_constraint_free(mrb_state *mrb, void *ptr)
{
  cpConstraint *constraint = ptr;
  mrb_cp_constraint_user_data *user_data;

  if (constraint) {
    user_data = cpConstraintGetUserData(constraint);
    if (user_data) {
      mrb_cp_constraint_user_data_free(mrb, user_data);
    }
    cpConstraintFree(constraint);
  }
}

Example #4

File: ofxChipmunkBody.cpp Project: underdoeg/ofxChipmunk

Body::~Body(){
	if(body){
		//clean up all constraints
		constraintsToRemove.clear();
		cpBodyEachConstraint(body, &constraintRemoveQuery, (void*)this);
		for(auto c: constraintsToRemove){
			((Constraint*)cpConstraintGetUserData(c))->constraint = nullptr;
			cpSpaceRemoveConstraint(cpConstraintGetSpace(c), c);
			cpConstraintDestroy(c);
		}

		//remove body
		cpSpaceRemoveBody(cpBodyGetSpace(body), body);
		cpBodyFree(body);
		body = nullptr;
