I'm working on a project and have basically just been following the format of existing attribute methods, which has worked well for me up to this point. The declaration I have been using looks something like this:

attr = jit_object_new(_jit_sym_jit_attr_offset_array,"speed",_jit_sym_float64,2,attrflags, (method)0L,(method)jit_boids3d_speed,calcoffset(t_jit_boids3d,speed));

jit_class_addattr(_jit_boids3d_class,attr);

This updates a variable named 'speed' in the '_jit_boids3d' jitter object. However, I've been trying to update a value in a separate struct, which the _jit_boids3d object has a pointer to. This current declaration causes Max to crash when the value is updated. The documentation for this is pretty sparse, does anyone have any more info on what the parameters actually do, and how I could update a value in a separate struct outside of the jitter object using attribute methods?
