An error would sometimes occur in my program. The popup dialog said: Script
error: Object has been deleted tCollisions =
whichWorld.ModelsUnderRay(wp,wd,howMany,#detailed) -2147196926 Yes, models
would be loaded and unloaded dynamically in my program. I guess this error is
cause by some model being deleted and collision detection doing at the right
time, is it? How can I overcome this error?
