Simulate Player +use on a entity

Sammy-ROCK! · **Author**

Hi. I was trying a way to spawn a gun and equip to player in the mod Zombie Panic Source. The problem is that GivePlayerItem spawns the gun under the player and since this mod doesn't pick the gun when you walk over it stays on the ground until player notices and grab. Also EquipPlayerWeapon adds the gun to the client's weapon inventory but it's not useable. If you select the slot that the gun is in it doesn't change to that gun. So I was thinking on make it like the player used +use on the gun so it'd equip properly.

For this mod the inputs of guns are:

Code:

SetTeam
Kill
KillHierarchy
Use
Alpha
AlternativeSorting
Color
SetParent
SetParentAttachment
SetParentAttachmentMaintainOffset
ClearParent
SetDamageFilter
EnableDamageForces
DisableDamageForces
DispatchEffect
DispatchResponse
AddContext
RemoveContext
ClearContext
DisableShadow
EnableShadow
AddOutput
FireUser1
FireUser2
FireUser3
FireUser4

I was thinking about using "Use" input but I'm not really sure how to make it work properly with AcceptEntityInput.

Code:

Syntax: native bool:AcceptEntityInput(dest, const String:input[], activator=-1, caller=-1, outputid=0); 

Usage:  dest        Destination entity index.
 input        Input action.
 activator    Entity index which initiated the sequence of actions (-1 for a NULL entity).
 caller    Entity index from which this event is sent (-1 for a NULL entity).
outputid    Unknown.

Try this:

PHP Code:


			
AcceptEntityInput(weapon_index, "Use", client, client);

Didn't work.

Code:

public OnPluginStart()
{
    RegAdminCmd("sm_weapon_equip", Command_Weapon, ADMFLAG_CHEATS)
}

public Action:Command_Weapon(client, args)
{
    if(args < 2)
    {
        ReplyToCommand(client, "Usage: sm_weapon_equip <target> <weapon or ammo>");
        return Plugin_Handled;
    }
    decl String:arg[MAX_NAME_LENGTH];
    GetCmdArg(1, arg, sizeof(arg));
    decl String:target_name[MAX_TARGET_LENGTH];
    decl target_list[MAXPLAYERS], target_count, bool:tn_is_ml;
    if((target_count = ProcessTargetString(arg, 0, target_list, MAXPLAYERS, 0, target_name, sizeof(target_name), tn_is_ml)) <= 0)
        return Plugin_Handled;
    GetCmdArg(2, arg, sizeof(arg));
    for(new i = 0; i < target_count; i++)
    {
        new target = target_list[i];
        new WeaponEnt = GivePlayerItem(target, arg);
        AcceptEntityInput(WeaponEnt, "Use", target, target);
        ReplyToCommand(client, "Equiped %N with a %s", target, arg);
        PrintToChat(target, "%N gave you a %s", client, arg);
    }
    return Plugin_Handled;
}

Try setting an empty entry in m_hMyWeapons to the entity index of the weapon. For example..

PHP Code:


			
new offset = FindSendPropInfo("CTFPlayer", "m_hMyWeapons");
for (new i = 0; i <= 47; i++)
{
    if (GetEntDataEnt2(target, offset+(i*4)) == 0)
    {
        new weapon = GivePlayerItem(target, arg);
        SetEntDataEnt2(target, offset+(i*4), weapon);
        break;
    }
}

You might want to do some testing to see what the blank value might be (it's probably not 0, like I put in the if statement).

Sammy-ROCK! · 08-02-2009 , 19:21 Re: Simulate Player +use on a entity

GetEntData2 returns -1 if no entity is found or it's invalid.

Code:

Entity index at the given location.  If there is no entity, or the stored entity is invalid, then -1 is returned.

Trying this.
Since in zps m_hMyWeapons is 40 bytes I decreased "i" to 9 max. (9x4 = 36 + 4 bytes = 40(limit))

It worked just like EquipPlayerWeapon. It shows in inventory. But the gun is still on the ground and the inventory slot shows the gun but if you press that key you holst. Also if you try to grab the gun you pick it's ammo (Game thing if you grab a gun you already have you get it's ammo).

Code:

public OnPluginStart()
{
    RegAdminCmd("sm_weapon_equip", Command_Weapon, ADMFLAG_CHEATS)
}

public Action:Command_Weapon(client, args)
{
    if(args < 2)
    {
        ReplyToCommand(client, "Usage: sm_weapon_equip <target> <weapon or ammo>");
        return Plugin_Handled;
    }
    decl String:arg[MAX_NAME_LENGTH];
    GetCmdArg(1, arg, sizeof(arg));
    decl String:target_name[MAX_TARGET_LENGTH];
    decl target_list[MAXPLAYERS], target_count, bool:tn_is_ml;
    if((target_count = ProcessTargetString(arg, 0, target_list, MAXPLAYERS, 0, target_name, sizeof(target_name), tn_is_ml)) <= 0)
        return Plugin_Handled;
    GetCmdArg(2, arg, sizeof(arg));
    new offset = FindSendPropInfo("CHL2MP_Player", "m_hMyWeapons");
    for(new i = 0; i < target_count; i++)
    {
        new target = target_list[i];
        new WeaponEnt = GivePlayerItem(target, arg);
        for (new d = 0; d < 10; d++)
        {
            if(GetEntDataEnt2(target, offset+(d*4)) == -1)
            {
                SetEntDataEnt2(target, offset+(d*4), WeaponEnt);
                break;
            }
        }
        ReplyToCommand(client, "Equiped %N with a %s", target, arg);
        PrintToChat(target, "%N gave you a %s", client, arg);
    }
    return Plugin_Handled;
}
