Flocal in AnyForce3D

Hi

I added AnyForce3D to the shank of the GaitVaughan model.I saw in the tutorial that the Flocal property makes the force perpendicular to the node.But after I used Flocal, I found that the force is not always vertical in motion.Can you tell me how to make the force always perpendicular to the node? Thank you very much.

Hi Chen,

The force you have applied is indeed following the reference frame you have listed.
but the drawing of it does not and that might have confused you.

The AnyDrawVector has a property called “GlobalCoord” which can be “On” or “Off” default is “On”

This means that when you draw it will display the vector you supply in global coordinates not local.

I would fix the problem in this way:

Set GlobalCoord=Off;

and set your vector in this way

Vec=.Flocal*0.01; //scaling factor applied

The code you have written to set Vec is wrong, this code would make a constant vector of {-0.3,-0.01,-0.04} displayed in global coords.

Best regards
