Thanks for your advice, but I suppose that some of you guys haven't read the whole topic. I'm not a newbie scripter and I know how to do many things unless I come across something new that I haven't dealt with yet. And I created a ped with animation, sticked camera to him, removed a real dead player to another place, made everything to create an illusion of death as if there were my dead player lying on the ground. But! If you had read previous page of this topic then you would have known that there is a very annoying bug with death in a car or other vehicle. You can't remove dead player from that vehicle in case of death. That was my largest problem.
As there is no way to fix that, I put up with it because I found a solution - function "spawnPlayer" that actually revives player. I just revive player at the moment of his death and spawn him at different location. That works fine even if you died in a car and lets me create ped, animations and other stuff on the dead spot. So I think that the problem is solved. But I reported a new issue on the bugtracker. And you can help to fix dead bugs in the future by leaving some comments on this page. Anyway thanks to everyone who tried to help me with this
