How do I play the attack animation

hello , im restarting to play with construct a bit more serious but ive run into a problem i cant figure out, maybe someone can help me

im doing a platformer beat em up

so the problem is, im writing my enemy AI (droid) and whenever he stops by the player with movetostop he should perform the attack animation, but hes not. he just stands still like in pause, but if i move away he resumes the run animation. heres my code

Try using "trigger once while true" together with the main condition on line 7. If you don't use it, the code keeps telling the droid to start the animation, what means it keeps going back to the first frame.
