problem whit animation

Hello everyone, I have a problem: I have an actor standing with a gun that shoots through an animation. I wish it every 2 or 3 seconds to lower as if to ward, and then rises to his feet and back to parry with the animation first. I just do not get it to stay down for as long as I want, gets up quickly! you could give me an example? please ... thank you all for your help and sorry for my English very rough

For example your animations should be something like;
1-) a.png
2-) b.png
3-) stay_down.png
4-) stay_down.png
5-) stay_down.png
6-) c.png
7-) d.png
etc.
You have the image sequence of few .png files for the animation, right?
And you want it to stay down longer. So, in the "Animation" behavior use .png files multiple times to extend the duration.
If you have 3 images;
smile.png
cry.png
hate.png
Lets say you want them to animate,
Animate ---> smile - cry - hate
But if you want it to cry more, you put cry.png multiple times in the Animate behavior;
Animate --> smile - cry - cry - cry - hate
I understand it, only that the actor has a spawner that makes him shoot once every 1 second when it is standing, and even if I add the file to animation png stay down, he continues to stand and shoot once every 1 second ..... do not know if I explained it well ...
