You may try :

for(all_entities)
{
while(moving from point P1 to P2 during time 0.1 seconds)
{
while(anim_percent < 100)
{
anim_percent += speed * time_step; // play with speed
//animate the walk
}
}
}


There is a snippet that does the similar
thing was posted in the forum if I remember
it right, you may search the forum.

Btw, how can you see the model animates
in such a short time?
