When I try to change level from my script level is loaded but there is no player and nothing works . In manual write something about that but dont understand how to do it . What I must do to load player and enemy models in new level and code and models will work in that new level ?
Thanks

Just load the new level via "level_load" again, all models, and stuff which are placed in that level via WED will be created automatically. Read manual for more info, search for "level_load".
