Attaching player to an entity functions

Attaching player to an entity functions

   I've tried to make a system that attaches a player to an entity (car, object, pickup or other player). Good for some events and stuff, for example if you try making an arrest system like in Brasil Real RPG, when the player 'follows' the cop, you can find this usefull. You can adapt the script to attach an object to an car , an pickup to a car, etc...

Functions:
[spoiler]
player.Attach( type, entity, offset);

Attaches a player to the specified entity with an offset.
Parameters:
type : string, to define what kind of entity is the player attached on.
entity: can be a player, object, vehicle or pickup instance.
offset: Vector, defines the offset the player is attached to the center of vehicle.

Example:

Code Select Expand

FindPlayer(0).Attach("CObject",FindObject(10),Vector(0,10,4.5))
player.Deattach();
De-ataches the player from the entity he was attached before.
Parameters: none.

Example:

Code Select Expand

FindPlayer(0).DeAttach()[/spoiler]

Installing:
Just put the 'attach_sys.nut' file from the downloaded archive in your /scripts/ folder then :

Code Select Expand

function onScriptLoad()
{
dofile("scripts/attach_sys.nut");
}

It can be improved by using squirrel table
Usage:
object & entity can be any of these types player/pckup/vehicle/object

Code Select Expand

attachEntity(instance object,instance entity,vector offset);
deattachEntity(instance object);

Snippet

Code Select Expand

g_Attach <- {}

function attachEntity(object,entity,offset)
{
if( g_Attach.rawin( object.ID ) ) print( "Object is already attached to an entity" );
g_Attach.rawset( object.ID, {
"Object": object,
"Entity": entity
"Offset": offset,
} );
}
function deattachEntity( object )
{
if( !g_Attach.rawin( object.ID ) ) print( "Object is not attached to any entity" );
g_Attach.rawdelete( object.ID );
}
function AttachUpdate()
{
foreach( id, attach in g_Attach )
{
if ( attach["Object"].Pos.x == 0 )
{
g_Attach.rawdelete( id );
continue;
}

if ( attach["Entity"].Pos.x == 0 )
{
g_Attach.rawdelete( id );
continue;
}

attach["Object"].Pos = attach["Entity"].Pos + attach["Offset"];
}
}

ATTACH_TIMER <- NewTimer("AttachUpdate",100,0);

Usage Example
/attach, /deattach

function onPlayerCommand(player, command, arguments)
{
switch( command )
{
case "attach":
if ( !arguments ) return MessagePlayer( "[#2add9b]Usage: /attach <player/pickup/vehicle/object> <id>", player );

local args = split( arguments, " " );
if ( args.len() < 7 ) return MessagePlayer( "[#2add9b]Usage: /attach <objType> <objid> <entityType> <entityID> <offsetX> <offsetY> <offsetZ> (Type: player/pickup/vehicle/object)", player );

local
objTp = args[0],
objID = args[1].tointeger(),
entTp = args[2],
entID = args[3].tointeger(),
offSetX = args[4],
offSetY = args[5],
offSetZ = args[6],
objIns,
entIns;
switch( objTp )
{
case "player": objIns = FindPlayer( objID ); break;
case "pickup": objIns = FindPickup( objID ); break;
case "vehicle": objIns = FindVehicle( objID ); break;
case "object": objIns = FindObject( objID ); break;
}
switch( entTp )
{

case "pickup": entIns = FindPickup( entID ); break;
case "vehicle": entIns = FindVehicle( entID ); break;
case "object": entIns = FindObject( entID ); break;
}

if ( !objIns || !entIns ) return MessagePlayer( "[#2add9b]One of the instance is not found.", player );
attachEntity( objIns, entIns, Vector( offSetX.tointeger(), offSetY.tointeger(), offSetZ.tointeger() ) );
MessagePlayer( "Attached object to entity.", player );
break;
case "deattach":
if ( !arguments ) return MessagePlayer( "[#2add9b]Usage: /detach <objType> <objid> (Type: player/pickup/vehicle/object)", player );

local args = split( arguments, " " );
if ( args.len() < 2 ) return MessagePlayer( "[#2add9b]Usage: /detach <objType> <objid> (Type: player/pickup/vehicle/object)", player );

local
objTp = args[0],
objID = args[1].tointeger(),
objIns;
switch( objTp )
{
case "player": objIns = FindPlayer( objID ); break;
case "pickup": objIns = FindPickup( objID ); break;
case "vehicle": objIns = FindVehicle( objID ); break;
case "object": objIns = FindObject( objID ); break;
}

if ( !objIns ) return MessagePlayer( "[#2add9b]The instance is not found.", player );
deattachEntity( objIns );
MessagePlayer( "Deattached object from entity.", player );
break;
}
} :edit:
Forget to add 'return' before 'MessagePlayer'

[MEGAMIND]

A suggestion, make it using if & else statement for other player to make it understandable instead if switch case

[Xmair]

People should learn using switch case then.

[NicusorN5]

People should learn using switch case then.

Totally agree.

Totally agree.

Agreed

This is something I had in mind. Nice one, pleb. You made my day.

[=RK=MarineForce]

how can i add ? when player type

{
player attack PickedID = 6000 how can i do this like simple Player.Attach.PickupID = 6005;
}

attach player ID

[NicusorN5]

@=RK=MarineForce You can remove the pickup and then create a flag object then attach it to an player.

attach player ID

If you have installed mine version you can attach any of the instance[ player, pickup, vehicle, object ] to any of instance[ player, pickup, vehicle, object ]
means for attaching pickup to bike

Code Select Expand

local instancePickup = FindPickup( integer pickupID );
local instanceVehicle = FindVehicle( integer vehicleID );

attachEntity( instancePickup, instanceVehicle,Vector( 0, 0, 3 ) );

 :edit: For the original snippet
Usage if I am not wrong Will not work better use the above one. Clk

Code Select Expand

local instancePickup = FindPickup( integer pickupID );
local instancePlayer = FindPlayer( integer playerID );

instancePlayer.Attach( "CPickup", instancePickup, Vector( 0, 0, 3 ) );


[NicusorN5]

It will attach the player to the pickup, so the player will remain stuck.
