Help with my project! PLISSS!

Hello, im new to Construct 2 and im creating a project, but i have 3 problems:

-How i can do when i do the mirrored and this shooting, this also shoot to the other side?

-When i press the key shutter, the audio duration of the time that i have the key pressed?

-And to finish, how can make when i go running and press "X" to shoot, the player to stop, and change the animation to fire? I thank you for your help! <img src="smileys/smiley20.gif" border="0" align="middle" />

-When shooting, set the angle of the spawned bullet to the angle of the gun/character, so it will face in the same direction.

-If I understood correctly, the best way would be to stop the audio when the key is no longer pressed.

-If the shoot event stops the player and changes its animation, then add another condition to the event that makes the player run to only run when the shooting animation is not being played.

OK thanks :)
