Hi Bocheng,
It now works, but it broke certain parts of my code. Seems some of the API
and syntax have changed in this version. I noticed changes in the SCM
terrain = veh.SCMTerrain(sys)
# rotate plane
terrain.SetReferenceFrame(chrono.ChCoordsysd(
chrono.ChVector3d(0, scm_plane_y, 0),
chrono.QuatFromAngleX(-math.pi / 2)
))
# Previous version used:
terrain.SetPlane(chrono.ChCoordsysd(
chrono.ChVector3d(0, scm_plane_y, 0),
chrono.QuatFromAngleX(-math.pi / 2))
)
Upon updating to the new version, I am now faced with a new error when
running the deformable soil ...
Cannot open colormap data file
C:/Users/chike/Box/TurtleRobotExperiments/Sea_Turtle_Robot_AI_Powered_Simulations_Project/NnamdiFiles/mujocotest1/chrono/data../data/colormaps/jet-table-float-0512.csv
I have the data path correctly specified at the top of my code using the
chrono.SetChronoDataPath()
And upon contact with the ground, the window crashes. Do you happen to have
any fixes for this? Also, are there any other changes to the syntax?
Best regards,
Nnamdi
