I have found a solution:
In the Character FPE file if have put this on top:
ai_classiccharacter_anubis_stopanim_trigger = 0
in the main i have put this:
if ai_classiccharacter_anubis_stopanim_trigger ==0 then
StopAnimation(e)
else
-----------------------------------------------
In the trigger i have put this:
if g_Entity[e]['plrinzone']==1 then
ai_classiccharacter_anubis_stopanim_trigger = 1
and now it works fine
