C4 TAKER v1.09
(For lack of a better name)

Description:
Enables you to take the C4 from a teammate by aiming at him/her and pressing the USE key. (default 'E')
This is especially useful when playing with bots either for gameplay or debug purposes...

Requires:
amxmodx | fakemeta_util | hamsandwich

CVARs:

c4t_admin_only [default 1] - limits the plugin for admin use only. Set to '0' so that everyone can take the C4. Set to '2' and admin gets the C4 automatically every start of a round.
c4t_take_from_humans [default 0 ]- set to '1' to enable to take C4 from human players
c4t_max_distance [default 120] - max distance for the take
c4t_hud [default 5] - number of instances the HUD Message appears. Set to '0' to disable. Can be set to '9999...'.

Notes:

Only Admins can take C4 by default
Max distance of the HUD message are the same which means it may serve as an indicator of sorts.
HUD message appears for certain amount of instances (set by a cvar) for each human player. After that it is disabled.
I did this because I found the HUD message annoying after a couple of rounds.
Based off joaquimandrade's and ConnorMcLeod's "EasyWeaponsTrade" plugin.
First submitted plugin. Please don't hang me. Just take my bacon if you want.:bacon!:

Re: C4 Bot Taker - joaquimandrade and ConnorMcLeod

const MaxSlots = 32
get_maxplayers(), unless pHit only returns players, then it's not even necessary to check.

new Float:MaxDistance = 200.0
cvar is never a bad idea, no big deal though.

num[] is never reset for new players that might inherit an old id.

Is it possible to aim at a dead player in StatusValue? (I don't actually know. I'm just checking if you checked)

Other than that, afaik, looks good.

Re: C4 Bot Taker - joaquimandrade and ConnorMcLeod

Nothing for say, just two words:

Nice job

Re: C4 Bot Taker - joaquimandrade and ConnorMcLeod

PHP Code:


		
			
public Use_Button(id) //Function when you press 'E' or the USE key

{

    if(is_user_connected(id))

        if(pev(id,pev_button) & IN_USE) //Checks if you pressed the USE key

            Take_C4(id); //Calls function to take C4

}

>>>

PHP Code:


		
			
public Use_Button(id) //Function when you press 'E' or the USE key

{

    if(is_user_alive(id))

        if(pev(id,pev_button) & IN_USE) //Checks if you pressed the USE key

            Take_C4(id); //Calls function to take C4

}

or dead players may get the c4 lol.

Re: C4 Bot Taker - joaquimandrade and ConnorMcLeod

Will be perfectly if we can take c4 with players, no only bots.

Re: C4 Bot Taker - joaquimandrade and ConnorMcLeod

Hey guys! I'm glad you liked the idea. Unfortunately it's going to be a busy week at work. I'll try to find some time edit the plugin.

I'm gonna add a couple of cvars for in game customization but as for anything in the 'getLookingAt' function, I'm going to need a bit help because that's the part I didn't write. I got straight from the EasyWeaponsTrade plugin. Don't worry, I'll just drop a few lines here if I run into problems.

Probably I'll start with the cvars tomorrow. Till then ...

Re: C4 Bot Taker - joaquimandrade & ConnorMcLeod

getLookingAt can be replaced with get_user_aiming. In fact, it's [almost] the same code.

Re: C4 Bot Taker - joaquimandrade & ConnorMcLeod

UPDATE 1.01
Ok guys I added 3 cvars for your gaming pleasure:

Quote:

c4bt_take_from_humans [default 0 ]- set to '1' to enable to take C4 from human players
c4bt_max_distance [default 200] - max distance for the take
c4bt_hud [default 5] - number of instances the HUD Message appears. Set to '0' to disable. Can be set to '9999...'.

Now it is possible for it to work with humans.

Use_Button function now looks like this, like JusTGo suggested:

PHP Code:


		
			
public Use_Button(id) //Function when you press 'E' or the USE key
{
    if(is_user_alive(id))
        if(pev(id,pev_button) & IN_USE) //Checks if you pressed the USE key
            Take_C4(id); //Calls function to take C4
}

Added a code when player disconnects resets num[] to 0 just as Black Rose advised:

PHP Code:


		
			
public client_disconnect(id) num[id] = 0 //Resets 'num' to 0 when a player disconnects

I studied some codes involving player disconnections. Is it really this simple? Sorry, still a noob.

StatusValue, as far as I know, do not trigger on dead players. The names and health percentages just don't show up.

As for this:

Quote:

const MaxSlots = 32
get_maxplayers(), unless pHit only returns players, then it's not even necessary to check.

I have no idea as of now...

EDIT:
====
In light of what Hamlet has just told me, I will next attempt to replace getLookingAt with get_user_aiming in an effort to make the plugin more efficient...

UPDATE v1.02
Replaced getLookingAt function with native get_user_aiming.

Re: C4 Bot Taker - joaquimandrade & ConnorMcLeod

Can you add a feature (for admins) to take c4 from a player and give to another.
amx_takebmb player_with_bomb target_player

Because if a noob doesn't plant it's annoying to find him and take c4 with aim.

BTW, nice plugin.
