isTouching()

I have made a method for detecting if a player is touching a weapon/turret/bombsite. Basically in any situation where the "Press (F) to use" dialog shows up.

Use example:

PHP Code:

---

if ( player isUseTouching() ) ... 


---

Install

Open gsc.cpp, CTRL + F and search for "resetNextReliableTime". Then add the following on a new line;

PHP Code:

---

{"isusetouching"         , gsc_player_isusetouching      , 0}, 


---

Open gsc_player.hpp, CTRL + F and search for "void gsc_player_resetNextReliableTime(int id);". Then add the following on a new line;

PHP Code:

---

void gsc_player_isusetouching(int id); 


---

Open gsc_player.cpp, CTRL + F and search for "// entity functions". Then add the following on a new line;

PHP Code:

---

void gsc_player_isusetouching(int id) {
    #if COD_VERSION == COD2_1_0
        int info_use_offset = 0x0811F004;
    #elif COD_VERSION == COD2_1_2
        int info_use_offset = 0x08121338;
    #elif COD_VERSION == COD2_1_3
        int info_use_offset = 0x08121494;
    #endif
    
    int entity = gentities + id * gentities_size;
    int base[2050];
    int res = 0;
    
    int (*isUseHover)(int a1, void *d);
    *(int *)&isUseHover = info_use_offset;
    
    res = isUseHover(entity, base);
    stackPushInt(res);
}

Compile your version and you are done.

It should not be called isTouching() because there is already a built-in function with that name to determine if you are within a trigger range. Call it something else please.

Yup was just about to edit before seeing this.

So if i'm understanding this right and from looking at the used function.

You are checking if the player is touching any triggers that is range.
The difference between 'isTouching' and this new function is that the default 'isTouching' requires you to specify the entity that you want to check.

PHP Code:

---

self isTouching(entity)
self isUseTouching() 


---

The function that you are using is called 'G_TouchTriggers'.
If i'm right it should return which entity you are triggering at the moment.

So maybe call the function: 'player getActiveTouchTrigger() or player getCurrentTouchTrigger()' (in case it does return an entity).

Edit: it doesn't return a entity. But it does notify the entities that someone triggers them.

Honestly I didn't even know there was a isTouching() function until after I posted this thread. Made the above method so that my sprint does not clash with stock weapon pickups. You can also block bots from picking up weapons/using turrets with a little tweaking.

Wouldn't it be more effective and useful to hook the call/function that is responsible for picking up weapons?
Then with a libcod function you can set if the player is allowed to pickup weapons or not.

Like this

PHP Code:

---

player enableWeaponPickup();
player disableWeaponPickup(); 


---

Maybe dumb question, but how to compile it?

I don't have the knowledge to do this yet. I'm still earning about C++ and libcod.

This is the information that i found so far.

PHP Code:

---

Touch_Item_Auto = 8105C80 (1.3), 81037F0 (1.0) 


---

It calls:

PHP Code:

---

Touch_Item(item_weapon, player, message = 0 / 1) 


---

Item_weapon and player are probably gentities.
So the function gentityaddress_to_num in gsc_player.cpp will probably give you a number between 0 and 63.

The function is called from:

PHP Code:

---

8187F64 (1.3), 8167AE4 (1.0)
8187F8C (1.3), 8167B0C (1.0)
8187FB4 (1.3), 8167B34 (1.0) 


---

These addresses are pointers to a function like closer or download.
Now you can try and replace these pointers with your own function and return to the original function.
Before return to the function you can add a message to see which of the addresses you need.

Here is disablePickup()

Usage example:

PHP Code:

---

self disablePickup(true); 


---

Also make sure to set disablePickup(bool) on player connect so it will reset properly.

Installation
Open gsc.cpp, CTRL + F and search for "resetNextReliableTime". Then add the following on a new line;

PHP Code:

---

{"disablepickup"         , gsc_player_disable_pickup     , 0}, 


---

Open gsc_player.hpp, CTRL + F and search for "void gsc_player_resetNextReliableTime(int id);". Then add the following on a new line;

PHP Code:

---

void gsc_player_disable_pickup(int id); 


---

Open gsc_player.cpp, CTRL + F and search for "// entity functions". Then add the following on a new line;

PHP Code:

---

void gsc_player_disable_pickup(int id)
{
    int disable;
    
    if ( ! stackGetParams("i", &disable)) {
        printf("scriptengine> ERROR: gsc_player_allow_pickup(): param \"disable\"[1] has to be an integer!\n");
        stackPushUndefined();
        return;
    }
    
    extern int disable_player_pickup[64];
    
    if(disable)
        disable_player_pickup[id] = (1);
    else
        disable_player_pickup[id] = (0);
} 


---

Open libcod.cpp, CTRL + F and search for "int hook_RemoteCommandTime(void)". Then add the following function before "int hook_RemoteCommandTime(void)";

PHP Code:

---

int disable_player_pickup[64] = {0};
int clientaddress_to_num(int client);

cHook *hook_disable_pickup;
int disable_pickup(int a1, int a2, int a3)
{
    int addrtype, ret = 0;
    int clientnum = clientaddress_to_num(a2);
    extern int playerinfo_base, playerinfo_size;
    if(*(int*)(*(int*)playerinfo_base + clientnum * playerinfo_size) == 4 && !disable_player_pickup[clientnum])
    {
        hook_disable_pickup->unhook();
        signed int (*sig)(int a1, int a2, int a3);
        *(int *)&sig = hook_disable_pickup->from;
        ret = sig(a1, a2, a3);
        hook_disable_pickup->hook();
    }
    return ret;
} 


---

Also while in libcod.cpp, add search and add the following new lines depending on your version;

1.0;
Search for "cracking_hook_call(0x080707C3, (int)Scr_GetCustomMethod);"

Add the following on a new line;

PHP Code:

---

            hook_disable_pickup = new cHook(0x080DCC7A, (int)disable_pickup);
            hook_disable_pickup->hook(); 


---

1.2;
Search for "cracking_hook_call(0x08070D3F, (int)Scr_GetCustomMethod);"

Add the following on a new line;

PHP Code:

---

            hook_disable_pickup = new cHook(0x080DF25A, (int)disable_pickup);
            hook_disable_pickup->hook(); 


---

1.3;
Search for "cracking_hook_call(0x08070E0B, (int)Scr_GetCustomMethod);"

Add the following on a new line;

PHP Code:

---

            hook_disable_pickup = new cHook(0x080DF39E, (int)disable_pickup);
            hook_disable_pickup->hook(); 


---

Compile your version and you are done.

The above function only disables weapon pickup and doesn't disable turrets, bomb planting etc.

As requested, I have added disablePickup(bool) to libcod for download.

I just noticed an unused variable in int disablePickup(int a1, int a2, int a3).

Replace

PHP Code:

---

int addrtype, ret = 0; 


---

With

PHP Code:

---

int ret = 0;

The code doesn't work correctly, because a2 isn't a client address but a gentity address.
You need to replace 'clientaddress_to_num' with 'gentityaddress_to_num' to get a valid client number.
Edit: the function uses a different a2 variable. So i was wrong. See: http://killtube.org/showthread.php?2...ll=1#post12093

Are you sure? This is what my log returns;

Code:

---

clientaddress_to_num = 0, gentityaddress_to_num = 1024

---

PHP Code:

---

    int clientnum = clientaddress_to_num(a2);
    int clientnum2 = gentityaddress_to_num(a2);
    printf("clientaddress_to_num = %i, gentityaddress_to_num = %i\n", clientnum, clientnum2);

    int clientnum2 = gentityaddress_to_num(a2);

Maybe it is a difference between 1.0 and 1.3 (= where i tested it).

Edit: In 1.3 i get this:

Code:

---

clientaddress_to_num = -55, gentityaddress_to_num = 0

Remove post

Here are the correct addresses:
1.2

PHP Code:

---

            hook_delete_weapon = new cHook(0x08105E9E, (int)delete_weapon);
            hook_delete_weapon->hook(); 


---

1.3

PHP Code:

---

            hook_delete_weapon = new cHook(0x08105FFA, (int)delete_weapon);
            hook_delete_weapon->hook(); 


---

I will update the above post with the fix. Triple edit: Seems like I can't =(

---

I'm using a function one level higher.

My function (gentity):

PHP Code:

---

sub_8105CAC(signed int s, int a2, int a3) 


---

Your function (client):

PHP Code:

---

result = sub_80DF39E(s, *(_DWORD *)(a2 + 344), a3); 


---

Edit: i committed my version. https://github.com/M-itch/libcod/com...6f7f20d91a895f

Are you sure you have set

PHP Code:

---

            hook_disable_pickup = new cHook(0x080DF39E, (int)disable_pickup);
            hook_disable_pickup->hook(); 


---

correctly?

EDIT: Going by your previous post, seems like you didn't.

By the way, the use of sub_80DF39E over sub_8105CAC is intentional. Using sub_80DF39E will only disable weapon pickup whereas sub_8105CAC will disable everything with a Use (f) dialogue. Hence why the custom function is called disablePickup and not disableUse.

My version works exactly the same.

Can you try this:
After you picked up a weapon and disabled the pickup.
You should be hearing the ammo pickup sound and the weapon will disappear and reappear when you go over the weapon again.
(+ not max ammo)

There are 3 pointers to the function Touch_Item_Auto and i only replace the last one (3).
1: This one is responsible for the 'Press [Use] to swap for ...' message.
2: No idea. I don't know how to trigger it. It might have something to do with picking up health.
3: Picks up the item.
