Easiest way is to add surface property is to use the ssgBase user_data field in the leafs and then use the a modified FGHitList::get_entity() method to return the touched leaf user_data. This could just be the pointer to the ssgTexture. Probably easiest to derive a fgTexture object from ssgTexture and add a surface property field This would require adding a field to the HitList that was set to the fgHitRec used note: I believe that this will always be the same as last_hit() but I haven't tested this and adding and maintaining an extra field won't hurt performance The actual call to do this would then be something like ((fgTexture *)(myHitList->get_entity(myHitList->get_active_entity())->get_user_data()->get_surface_property(); Norman _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
