Detect if player is hitting a door - AidanRO - 13.03.2016

Hello, today I want some help from you guys.

I recently wanted to remake the way you break in a car on my server. So, now I want to know how I can detect if a player is hitting any of the doors with his fist or baseball bat, or anything.

Is there any way to do that?
Thanks.

Here's a snippet to detect when a player is NOT at any of the doors but rather at the trunk or hood. Credits go to Emmet_:

PHP код:



IsPlayerNearBoot(playerid, vehicleid) {


    static

        Float:fX,

        Float:fY,

        Float:fZ;


    GetVehicleBoot(vehicleid, fX, fY, fZ);


    return (GetPlayerVirtualWorld(playerid) == GetVehicleVirtualWorld(vehicleid)) && IsPlayerInRangeOfPoint(playerid, 3.5, fX, fY, fZ);

}


IsPlayerNearHood(playerid, vehicleid) {


    static

        Float:fX,

        Float:fY,

        Float:fZ;


    GetVehicleHood(vehicleid, fX, fY, fZ);


    return (GetPlayerVirtualWorld(playerid) == GetVehicleVirtualWorld(vehicleid)) && IsPlayerInRangeOfPoint(playerid, 3.0, fX, fY, fZ);

}


GetVehicleBoot(vehicleid, &Float:x, &Float:y, &Float:z) {


    if (!GetVehicleModel(vehicleid) || vehicleid == INVALID_VEHICLE_ID)

        return (x = 0.0, y = 0.0, z = 0.0), 0;


    static

        Float:pos[7]

    ;

    GetVehicleModelInfo(GetVehicleModel(vehicleid), VEHICLE_MODEL_INFO_SIZE, pos[0], pos[1], pos[2]);

    GetVehiclePos(vehicleid, pos[3], pos[4], pos[5]);

    GetVehicleZAngle(vehicleid, pos[6]);


    x = pos[3] - (floatsqroot(pos[1] + pos[1]) * floatsin(-pos[6], degrees));

    y = pos[4] - (floatsqroot(pos[1] + pos[1]) * floatcos(-pos[6], degrees));

     z = pos[5];


    return 1;

}


GetVehicleHood(vehicleid, &Float:x, &Float:y, &Float:z) {


    if (!GetVehicleModel(vehicleid) || vehicleid == INVALID_VEHICLE_ID)

        return (x = 0.0, y = 0.0, z = 0.0), 0;


    static

        Float:pos[7]

    ;

    GetVehicleModelInfo(GetVehicleModel(vehicleid), VEHICLE_MODEL_INFO_SIZE, pos[0], pos[1], pos[2]);

    GetVehiclePos(vehicleid, pos[3], pos[4], pos[5]);

    GetVehicleZAngle(vehicleid, pos[6]);


    x = pos[3] + (floatsqroot(pos[1] + pos[1]) * floatsin(-pos[6], degrees));

    y = pos[4] + (floatsqroot(pos[1] + pos[1]) * floatcos(-pos[6], degrees));

     z = pos[5];


    return 1;

}

This should give you an idea on how to detect the door positions. Keep in mind that when doing so you have to check for quite the possible cases: is the player hitting a bike, is the player hitting a golf cart, How many doors does the vehicle have, etc..

Thanks for that. Basically, that should work with OnPlayerKeyStateChange and detect if player is in the "fisting" animation, right?

Re: Detect if player is hitting a door - AndySedeyn - 13.03.2016

You can check if the player has a gun out or just his fist. You can then check if the player is attacking in OnPlayerKeyStateChange and then check what the player's position is.

> Player presses RMB (or the assigned key to attack)
> Does player have his fist out, or a particular weapon?
> Is the player in range of a vehicle's door?

Here is the wiki page to all the keys detectable by SAMP: https://sampwiki.blast.hk/wiki/Keys
And the following snippet holds three macro functions to detect when a player is tapping, holding or just released a key:

PHP код:



#define HOLDING(%0)             ((newkeys & (%0)) == (%0))

#define PRESSED(%0)             (((newkeys & (%0)) == (%0)) && ((oldkeys & (%0)) != (%0)))

#define RELEASED(%0)         (((newkeys & (%0)) != (%0)) && ((oldkeys & (%0)) == (%0)))

I don't know who the credits go to, but I got these from Abagail's topic: https://sampforum.blast.hk/showthread.php?tid=491980

Job done.
Thanks a lot Andy. I managed to detect the each doors's pos easy.

God bless.

This can be closed. Everything has been done.
