find_closest_bone_to_gunshot

This gets the closest bone to the gunshot (Use this in FM_TraceLine and Ham_TraceAttack):

#define DISTANCE_CLEAR_HIT        2.0
 
stock find_closest_bone_to_gunshot(victim, Float:endtrace[3])
{
    new Float:angles[3], Float:origin[3], Float:dist = 9999999.99, Float:curorigin[3], bone_nr
    for (new i=1;i<=54;i++)
    {
        // Get the bone position
        engfunc(EngFunc_GetBonePosition, victim, i, curorigin, angles)
        // Calculate the distance vector
        xs_vec_sub(curorigin, endtrace, angles)
 
        // If this is smaller than the last small distance remember the value!
        if (xs_vec_len(angles) <= dist)
        {
            origin = curorigin
            dist = xs_vec_len(angles)
            bone_nr = i
        }
 
        // If distance is smaller than CLEARHIT! Break (We accept the last value!)

        {
            break
        }
    }
 
    // Return the bone
    return bone_nr
}

Messaging Functions

EngFunc_MessageBegin

This function is used to generate client messages.

Usage

Syntax:

engfunc(EngFunc_MessageBegin, dest, msg_type, origin[3] = {0, 0, 0}, player = 0)

Example:

static Float:origin[3] // Origin should be a Float
pev(id, pev_origin, origin) // Get user origin
engfunc(EngFunc_MessageBegin,MSG_BROADCAST,SVC_TEMPENTITY,origin,0) // Create message

With MSG_ONE_UNRELIABLE:

engfunc(EngFunc_MessageBegin,MSG_ONE_UNRELIABLE,SVC_TEMPENTITY,_,id) // Create message

With MSG_ALL:

engfunc(EngFunc_MessageBegin,MSG_ONE_UNRELIABLE,SVC_TEMPENTITY,_,id) // Create message

dest can be:

#define    MSG_BROADCAST               0        // Unreliable to all, There is not id
#define    MSG_ONE                     1        // Reliable to one (msg_entity)
#define    MSG_ALL                     2        // Reliable to all, There is not origin
#define    MSG_INIT                    3        // Write to the init string
#define    MSG_PVS                     4        // Ents in PVS of org
#define    MSG_PAS                     5        // Ents in PAS of org
#define    MSG_PVS_R                   6        // Reliable to PVS
#define    MSG_PAS_R                   7        // Reliable to PAS
#define    MSG_ONE_UNRELIABLE          8        // Send to one client, but don't put in reliable stream,
                                                // put in unreliable datagram (could be  dropped), there is not origin
#define    MSG_SPEC                    9        // Sends to all spectator proxies

Before calling another EngFunc_MessageBegin you must call message_end().

Entity Search Functions

EngFunc_FindEntityInSphere

Find entities within a radius. The function returns the next entity id after the start entity.

3D diagram to show how the function works.

If we use

engfunc(EngFunc_FindEntityInSphere, -1, origin, radius)

In the situation described on the picture the function call above will return 1,

engfunc(EngFunc_FindEntityInSphere, 20, origin, radius)

will return 30 and

engfunc(EngFunc_FindEntityInSphere, 100, origin, radius)

will return 0, meaning that it didn't find an entity with an id grater than 100.

Usage

engfunc(EngFunc_FindEntityInSphere, ent_to_start, origin, radius)

EngFunc_EntitiesInPVS

This function checks entities that are in the PVS of an entity. It can't be used on worldspawn.

The function returns the first entity on the PVS and then you can traverse through the results using pev_chain/EV_ENT_chain. A NULL value of pev_chain/EV_ENT_chain indicates the end of the chain.

Usage

public whatisonPVS(id)
{
    static next, chain
    static class[32]
 
    next = engfunc(EngFunc_EntitiesInPVS, id)
    while(next)
    {
        pev(next, pev_classname, class, charsmax(class))
        chain = pev(next, pev_chain)
 
        server_print("Found entity in player (%i) PVS: ent(%i) class(%s)", id, next, class)
 
        if(!chain)
            break
 
        next = chain
    }
}

EngFunc_FindEntityByString

Returns the first entity found that matches the search criteria.

You can use any of string type attributes of entities:

classname	Type of entity
globalname	This is the name of the global variable that can be used to control the state of the entity
model	 	The model of the entity
target	 	Entity that this entity is handling
targetname	The name given to this entity that another entity searches for to handle it
netname		Player or NPC name
message		Seems to be used mainly to store sound (string). It happens to store others things, depending the need of the entity
noise		Noise variables do different things for different ents
noise1		This is the move sound for doors
noise2		This is the stop sound for doors
noise3		This is for blocking game_player_equip and player_weaponstrip

Usage

iEnt = engfunc(EngFunc_FindEntityByString, iStartEnt, sAttribute, sValue)

Parameters:

  • iStartEnt: Start searching on this entity (ex: 0 = worldspawn)
  • sAttribute: Name of attribute over which we need to search (ex: classname)
  • sValue: Text string that we are searching for (ex: func_breakable)

The function returns the first entity matching the criteria.

EngFunc_FindClientInPVS

Returns the next "player" entity in someone's PVS using a global loop.

Usage

iEnt2 = engfunc(EngFunc_FindClientInPVS, iEnt)

Parameters:

  • iEnt Source entity. Seek someone within iEnt's PVS

Unlike EntitiesInPVS, it does not return a series of chained entities. Instead, it works like a global loop of entities. No matter which source entity you use, this function maintains the last index used and returns the next entity in source entity PVS.

This function must be called several times to find every entity in PVS and can also return the source entity but it can't be called twice inside the same function because it will return the same entity.

Notes

It's not clear the main purpose of this function because you can get similar results with EntitiesInPVS.

CheckVisibility and EntitiesInPVS are better functions to use.

Trace Functions

EngFunc_TraceLine

This function traces between 2 origins and gives us information about it.

These are the constants we can use as flags:

#define DONT_IGNORE_MONSTERS            0
#define IGNORE_MONSTERS                 1
#define IGNORE_MISSILE                  2
#define IGNORE_GLASS                    0x100

These constants can be used together.

Ex: IGNORE_MISSILE | IGNORE_MONSTERS | IGNORE_GLASS - This makes the traceline ignore missiles, monsters (players) and glass.

Usage

Example of doing a traceline between two origins, and ignoring glass:

engfunc(EngFunc_TraceLine, start, end, IGNORE_GLASS, 0, tr)

Now considering glass:

engfunc(EngFunc_TraceLine, start, end, DONT_IGNORE_MONSTERS, 0, tr)

Other Traceline functions

This creates a trace handle. It's important to do this because we don't want our plugins to mess with eachothers info.

new ptr = create_tr2()

And this frees the trace handle:

free_tr2(ptr)

Getter and setter:

[g|s]et_tr2(trace_handle, CONSTANT, argument_if_setting)

Where CONSTANT can be one of the following enumerations:

enum TraceResult
{
	TR_AllSolid,		// int
	TR_StartSolid,		// int
	TR_InOpen,		// int
	TR_InWater,		// int
	TR_flFraction,		// float
	TR_vecEndPos,		// float array[3]
	TR_flPlaneDist,		// float
	TR_vecPlaneNormal,	// float array[3]
	TR_pHit,		// int (edict_t*)
	TR_iHitgroup,		// int
};

Getting the array and Float values require the third parameter to be passed.

Example:

    new startsolid = get_tr2(trace, TR_StartSolid)
    // TR_StartSolid is a boolean that says whether you were "inside" something 
    // (usually the world) when the trace started (point A)
    // TR_AllSolid tells you if you ever got out of the "inside" or not.
 
    new inopen = get_tr2(trace, TR_InOpen)
    // TR_InOpen means that the start point is in Open
    // That means in the world and not in an ent or something
 
    new hit = get_tr2(trace, TR_pHit)
    // What was hit by the traceline. It will either be a player index,
    // entity index, 0 (part of map), or -1 (didn't hit anything; 
    // doesn't happen with player tracelines).
 
    new hitgroup = get_tr2(trace, TR_iHitgroup)
    // If the traceline hit another player, returns will be HIT_HEAD,
    // HIT_CHEST, HIT_LEFTLEG... etc. If the traceline hit part of the
    // map, this returns HIT_GENERIC.
 
    new Float:fraction
    get_tr2(trace, TR_flFraction, fraction)
    // Returns a number between 0.0 and 1.0, indicating how far the
    // traceline traveled start to end before it hit something. Depending
    // on what conditions were passed to this traceline forward function,
    // it could either be a wall or another entity.
 
    new Float:end_origin[3]
    get_tr2(trace, TR_vecEndPos, end_origin)
    // The official end of the traceline. Not necesarily the same as the
    // second argument passed to this traceline forward function.
 
    new Float:normal[3]
    get_tr2(trace, TR_vecPlaneNormal, normal)
    // Returns a 1 unit long vector normal to the spot that it hit. Note
    // that "normal" has a special connotation here. It doesn't mean "regular."

Useful Stocks

is_wall_between_points

This returns true if there's a wall between start and end.

stock is_wall_between_points(Float:start[3], Float:end[3], ignore_ent)
{
    // Create the trace handle! It is best to create it!
    new ptr = create_tr2()
 
    // The main traceline function!
    // This function ignores GLASS, MISSILE and MONSTERS!
    // Here is an example of how you should combine all the flags!
    engfunc(EngFunc_TraceLine, start, end, IGNORE_GLASS | IGNORE_MONSTERS | IGNORE_MISSILE, ignore_ent, ptr)
 
    // We are interested in the fraction parameter
    new fraction
    get_tr2(ptr, TR_flFraction, fraction)
 
    // Free the trace handle (don't forget to do this!)
    free_tr2(ptr)
 
    // If = 1.0 then it didn't hit anything!
    return (fraction != 1.0)
}

EngFunc_TraceTexture, DLLFunc_PM_FindTextureType

The TraceTexture function detects the texture of an entity from a direction

The FindTextureType function allows to get the type of the material of the texture.

Usage

engfunc(EngFunc_TraceTexture, ent, Float:start[3], Float:end[3], texture_name, len)
  • ent is the entity that we want to get the texture
  • start is the point from where the trace starts
  • end is the point where the trace ends
  • texture_name - here we save the texture name
  • len - the texture_name string length


dllfunc(DLLFunc_PM_FindTextureType, texture_name)
  • texture_name is the name of the texture that we have gotten with TraceTexture

The function returns the material of the texture, which can be one of the following:

  • C : concrete
  • D : dirt
  • G : grate
  • M : metal
  • N : snow
  • P : computer
  • S : slosh
  • T : tile
  • V : ventilation
  • W : wood
  • Y : glass


Example:

new texture_name[64], texture_type
    engfunc(EngFunc_TraceTexture, 0, start, end, texture_name, charsmax(texture_name))
    texture_type = dllfunc(DLLFunc_PM_FindTextureType, texture_name)

Notes

Improper use of these functions may crash the server!

To avoid crashing the server use the TraceTexture:

  • on any entities (even worldspawn) except players
  • when there is at least one player connected
  • with a big distance between the two points (> 2000.0)


EngFunc_TraceModel

This function traces between 2 origins a model and gives us properties about it. It acts just like a TraceLine but it ignores all the entities except the one we want to hit!

Usage

engfunc(EngFunc_TraceModel, const Float:start[3], const Float:end[3], hull, ent_to_hit, ptr)
  • start - start origin
  • end - end origin
  • hull - the hull that is moved check above to see them
  • ent_to_hit - the entity that you want to hit (this is a must!)
  • ptr - the trace handle pointer, acts the same as the one in trace line!

The constants that we can use in hull:

#define HULL_POINT                      0  // This means that we are moving a point from the start to the end
#define HULL_HUMAN                      1  // That means that we move a cube of a player from start to end
#define HULL_LARGE                      2  // That means that we move a bigger cube that one of the player from start to end
                                           // (used in HL for big monsters!)
#define HULL_HEAD                       3  // This means that we move from start to end the hull of a ducked player

TraceLine explanation

EngFunc_TraceToss

Trace the point where some entity movement will finish. If for some reason the entity movement must be blocked for other entity (or worldspawn), TraceToss will detect that situation taking in account the original entity bounding boxes.

Usage

engfunc(EngFunc_TraceToss, ent, skipent, tr)
  • ent = The entity which movement we want to trace
  • skipent = The entity to skip in trace
  • tr = trace handle to store the result
EngFunc_TraceToss example

Example

In the image you can see a player jumping and 2 points.

Start Point is the origin of the player when TraceToss was called.

End Point is the point returned in TR result.

So the player is making a parabola from START to END. The green line is only for testing purposes and show from where to where the trace is. This was tested with gravity = 400.

Model/Decal/Texture Functions

EngFunc_SetModel

Properly sets a new model on an entity.

Usage

engfunc(EngFunc_SetModel, iEnt, sModel)
  • iEnt = Entity index
  • sModel = Model file name to set on entity (ex: "models/player/vip/vip.mdl")

Engine Alternative

entity_set_model(entity, model[])

[FuncWiki page for entity_set_model]

EngFunc_ModelIndex

Returns an unique index of the model name provided. It's actually the same number that precache_model() returns.

A model index is used for example in some TE_* messages. ( TE_LIGHTNING, TE_GLOWSPRITE, etc.. See message_const.inc file ).

The model index of an entity is stored in pev_modelindex.

Usage

ModelIndex = engfunc(EngFunc_ModelIndex, "models/MyModel.mdl")

ModelIndex will have the model index for "models/MyModel.mdl" after the function call.

EngFunc_ModelFrames

Returns the frames count of a model.

Usage

ModelFrames = engfunc(EngFunc_ModelFrames, ModelIndex)
  • ModelIndex = The model index. Value you can get from precache_model() or EngFunc_ModelIndex.


EngFunc_DecalIndex

Returns an unique index of the decal name provided.

A decal index is used for example in some TE_* messages. ( TE_PLAYERDECAL, TE_DECAL, etc.. See message_const.inc file ).

All the available decals are stored in the decals.wad file. ( Located at your mod root directory )

As side-note a plugin ["Decals/Models Lister"] is available to see a list of decals/models index/name. ( Only CS and HL )

Usage

DecalIndex = engfunc(EngFunc_DecalIndex, "{bigshot1")

DecalIndex will have the decal index for "{bigshot1" after the function call.

Engine alternative

DecalIndex = get_decal_index( "{bigshot1" )

[FuncWiki page for get_decal_index()]

EngFunc_AnimationAutomove

Plays the selected animation on entity

Usage

entity_set_float(iEnt, EV_FL_framerate, fFrameRate);
entity_set_int(iEnt, EV_INT_sequence, iSequence);
engfunc(EngFunc_AnimationAutomove, iEnt, fTime);
  • fFrameRate = Frame rate of desired animation.
  • iSequence = Sequence to play.
  • iEnt = Source entity.
  • fTime = It seems to not affect the animation. Maybe for internal use.

First you have to select the sequence and the desired frame rate. Then you can start the animation. It will run in an endless loop.

It seems to work only on non-player entities.

Entity/Global Functions

  • iEnt = Entity index
  • Destination[3] = A Coordinate toward which the entity moves
  • Distance = The distance to move the entity
  • iMoveType = This is the MOVE_* option used for monsters and players to change the behaviour of the movement

Move type possible values:

#define MOVE_NORMAL		0	// normal move in the direction monster is facing
#define MOVE_STRAFE		1	// moves in direction specified, no matter which way monster is facing
#define MOVE_STUCK_DIST		32	// if a monster can't step this far, it is stuck.
#define MOVE_START_TURN_DIST	64	// when this far away from moveGoal, start turning to face next goal

Caveats

  • iEnt must be on ground
  • If there's an object closer than Distance that iEnt could collide then the movement is not done
  • If there's a ramp, it works like an object and the movement is not done

Visibility Functions

EngFunc_CheckVisibility

This function is used to check if an entity is in your PVS.

It can be used on all entities except worldspawn.

Usage

This function has a parameter that must be obtained in a special way, the pset parameter. Note: The parameter is player only, that means that if you get pset for example for a player that has the id 1. When you use this function on an entity it will check whether that entity is in PVS of the Player id 1.

new g_cl_pset[33]
 
public plugin_init(id)
{
    register_forward(FM_AddToFullPack, "pfw_atfp", 1)
}
 
public pfw_atfp(es, e, ent, host, flags, player, set)
{
    g_cl_pset[host] = set
 
    return FMRES_IGNORED
}
 
stock is_ent_in_player_pvs(id, entity)
{
    return engfunc(EngFunc_CheckVisibility, entity, g_cl_pset[id])
}
 
stock get_pvs_players(id, players[32], num, flags[], team[])
{
    if (!is_user_connected(id))
        return 0    
 
    get_players(players, num, flags, team)
 
    for (new i=0;i<num;i++)
    {
        if (!is_ent_in_player_pvs(id, players[i]))
        {
            num--;
 
            for (new j=i;j<num;j++)
            {
                players[j] = players[j+1]
            }
 
            i--
        }
    }
 
    return 1
}

Other Functions

EngFunc_PrecacheModel

Precaches a model or sprite file.

This should be used only when you would need to postpone the precache process in plugin_init() or plugin_cfg(), otherwise you should use precache_model() native directly in plugin_precache() forward.

It can be useful for example when you want to manage models with cvars and to avoid registering them in plugin_precache() then getting some trouble, you could manage out of this forward.

Usage

engfunc(EngFunc_PrecacheModel, "models/MyModel.mdl")
engfunc(EngFunc_PrecacheModel, "sprites/MySprite.spr")

It returns the precached model/sprite index if successful, otherwise 0.

EngFunc_PrecacheSound

Precaches a sound, only *.wav file. ( for mp3, see EngFunc_PrecacheGeneric )

This should be used only when you would need to postpone the precache process in plugin_init() or plugin_cfg(), otherwise you should use precache_sound() native directly in plugin_precache() forward.

It can be useful for example when you want to manage sounds with cvars and to avoid registering them in plugin_precache() then getting some trouble, you could manage out of this forward.

Usage

engfunc(EngFunc_PrecacheSound, "sound/MySound.wav")

It returns the precached sound index if successful, otherwise 0.

EngFunc_AlertMessage

Prints an alert message.

Usage

engfunc(EngFunc_AlertMessage, AlertType, const Message)

AlertType can be:

at_notice - shows a message box with the message
at_console - same as at_notice, but forces a ConPrintf, not a message box, prints output to server console, but only if 'developer' is 1.
at_aiconsole - same as at_console, but only shown if 'developer' is 2.
at_warning -
at_error -
at_logged - prints output to server logs and console.
