Do you mean something like this in my video?

Yes. It's very great. Did you make this? Very nice work!
I need a sentry gun like that, too.
Can you help me please?

Thank you,

Have you not started making your own? I'm not just giving you my code lol.. but i'll help you along.

Yes i have already started it, but i can't finish It, because i don't know how to tell him to shoot another players (only enemies).

I only need the shooting part of the code.
So i can place the sentry, and i can remove it after 2 mins, or something like that, but don't know how to make It to shoot enemies.

Thanks,
Stalph

just check if the player is in the sentry gun radius and if so play damage to the player till he gets out of the trigger and play a shooting effect from the sentry gun so it looks like the sentry gun is shooting the player.

i made that, but what about the walls?

When i place the sentry, it shoots threw the wall.
How to fix it?

never made a sentry gun before but im thinking if you have a bullettrace from the player to the sentry model and check its fraction and if its not = 1 then the player or sentry or w.e is behind a wall so dont do damage to the player and stop shooting.

I know i have to make trace=bullettrace, but don't know how to make it.
What to write, so i'm in trouble.

And I know i have to calculate vectors but don't know how.

trace = bulletTrace(<start origin>, <end origin>, <hitPlayers true/false>, <ignoreEntity>);

The only vector calculation is working out the angle the sentry should be to face the player, which is just 1 line of code

sentry.angles = vectortoangles(<target origin> - <start origin>);
