Hi

thanks for sharing your code,

I think you referenced methods that doesn't exist in the "https://github.com/HJReachability/ilqgames/tree/v0.0.2"

in receding_horizon_planner.cpp for example,
this type
const ConcatenatedDynamicalSystem& dynamics,

doesn't have this method SubsystemXDim(ii),

hence the ros package cannot be built, also when somebody tries to build the external package it clones v.0.0.1 instead of v.0.0.2 and the methods won't match for compilation. It would be great if you tell us which version matches with this rosnode

in the script, line 216, the Splice method need time argument as well for v.0.0.2

    ros_time=ros::Time::now().toSec();
    solution_splicer_->Splice(*log, ros_time)

such case is also for the two other scripts,
in three_player_vicon_demo.cpp line 114 uses an overload of ConcatenatedDynamicalSystem that doesnt exist in the class definition.

it would be great if you could address these
