How to determine who fired into alarm car. This trigger is appropriate?
triggered_car_alarm
But he did not describe the structure. How to use this game event?

[McFlurry]

I would suggest using SDKHooks and using its trace attack function then check that the entity they shot is what ever the car alarm entity is(have to look it up) if the player is within the activation range(have no idea what it is) return client or use client how you want to.

From modevents.res file

PHP Code:

    "triggered_car_alarm"
    {
    } 


There is no structure.


Same file

PHP Code:

    "explain_disturbance"        // explain that disturbances (car alarm) attract infected horde
    {
        "userid"    "short"
        "subject"    "long"        // The source of disturbance
    } 


Maybe that can help you.



There is also the way of SDKHooks, i would try OnTakeDamage.

Thanks for help. It turns out harder than I thought. I just wanted to print into chat player nickname on who triggered car alarm. Similarly, a chat message when a witch scare.
explain_disturbance this trigger does not fit

You could try HookEntityOutput and get the Outputs of prop_car_alarm's "OnCarAlarmStart" and whatever the Witch has when triggered
