isTouching()

[filthy_freak_]

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:

		if ( player isUseTouching() ) ... 
	

Install

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

		{"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;

		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;

		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.

		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

		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.

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

It calls:

		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:

		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.
