Thank you so much for your precious help!!! You've absolutely cleaned up all, I'm really grateful to you!!!
Your comments also helped me in understanding, since it's my first time with a tool like construct. And thank you so much for adding the autofire for the mitra!!!
The artist who made the artwork thanks you a lot for the compliment, she really appreciate it!!! I think she's really gifted ^_^
By the way, I still have a question: as you can see, there is a problem with the animation.
a) Pistol: when the ctrl button is released, the "run" or "idle" animation isn't on sync with the rest of the body (instead it should be like it happena on event 12 and 13. Apparently the sprite "pistol" lose it's connection point to the body or just pick up the one for the curren body frame... I honestly can't figure it out;
b) Mitra: same stuff as for pistol, but also there is the problem about the fact that "fire" animation (for the mitra) still runs after the ctrl is released.
Have you got an idea? I'm hitting walls with my head 'cos of it :D
