it's a to0 long code bro,. hehe.. but the thing is that it works on the first run of the system, i just point it in the same function, but it doesnt work.
algorithm is like below:

function playagain()
{

laod_entity();
}

action move()
{
......ent_animate

if enemy or player' health==0

ent_animate(death)

playagain();

}

function load_entity(){

ent_create("player.mdl", vector(0,-100,-10),move);

}
