good day game makers...

i've made some nice animation which i want to put in my entity when, the enemy'll be dead,animations'll play.basically it means when entity heath=0,animation'll start and so it'll look like when i shoot enemy he'll falls down with my animation.but the main problem is when i setup all this and did a test,it worked perfectly but just animation was repeated(loop).so it looks like i kill enemy and he fall down and again up and again fall down.......so i guess may b u guys can help me with this..thanks in advance
