1. SA-MP Streamer Plugin v2.7.4
============================
Preface
-------
This plugin streams objects, pickups, checkpoints, race checkpoints,
map icons, and 3D text labels at user-defined server ticks. Basic
area detection is also included. Because it is written entirely in
C++, much of the overhead from PAWN is avoided. This streamer, as a
result, is quite a bit faster than any other implementation currently
available in PAWN.

Instructions
------------
Create a directory called "plugins" inside of the server directory if
one does not already exist. Place the plugin file (streamer.dll or
streamer.so) inside of this directory.
Add the following line to server.cfg so that the plugin will load the
next time the server starts:
Windows:
plugins streamer.dll
Linux:
plugins streamer.so
On Windows, add streamer.inc to the pawnoinclude folder. Include
this file in any of the scripts the server is running:
#include <streamer>
Recompile the scripts with any desired natives and callbacks provided
by the include file. Start the server.
General Notes
-------------
- Default tick rate: 50
- Default maximum items: none (unlimited)
- Default visible items: 500 (objects); 4096 (pickups); 1024 (3D text
labels)
- If -1 is specified for any of the optional parameters (worldid,
interiorid, or playerid), then the items will be streamed for all
virtual worlds, interiors, or players.
- The tick rate does not represent any specific measurement of time
and varies depending on the server's processing power. If items
stream too slowly, lower the tick rate; if CPU usage gets too high,
raise the tick rate.
- If some items are not appearing, there may be too many in one area.
Lower the streaming distance by decreasing the "streamdistance"
parameter on each native.
- Not all types of items have to be streamed. If the plugin is only
used to stream objects, for example, then every other native can be
safely ignored.
- Be careful when using streamed items with non-streamed items.
Conflicts can sometimes arise.
- Because there are no per-player pickups, a pickup that is streamed
for one player will be visible for all other players as well,
provided that those players are all in the same virtual world.
- A maximum of 1000 player IDs (0-999) can be assigned per item.
7. - The maximum amount of visible objects may be increased to 999 as of
SA-MP 0.3d, though it is not recommended for all of these objects
to be in one area due to game engine limits. By default, the number
of visible objects is set to 500 to avoid conflicts.
- Ensure that all scripts are compiled with the latest include file.
Native Notes
------------
- Use Streamer_UpdateEx to preload items before setting a player's
position or to stream items under OnPlayerRequestClass.
- Virtual worlds, interiors, and players can be modified or read
through the array data manipulation natives (Streamer_GetArrayData
and Streamer_SetArrayData, for example).
- Here is an example of using the data manipulation natives (note the
use of the definitions and the enumerator above):
Streamer_SetIntData(STREAMER_TYPE_OBJECT, objectid, E_STREAMER_MODEL_ID,
1225);
- Here is another example for data stored as arrays (virtual worlds,
interiors, and players):
Streamer_AppendArrayData(STREAMER_TYPE_OBJECT, objectid, E_STREAMER_PLAYER_ID,
playerid);
- To adjust an object's draw distance (added in SA-MP 0.3b), use
Streamer_SetFloatData with E_STREAMER_DRAW_DISTANCE. Alternatively,
use CreateDynamicObject(Ex). An object's default draw distance can
be set by specifying 0.0.
- To adjust a map icon's style (added in SA-MP 0.3c), use
Streamer_SetIntData with E_STREAMER_STYLE. Alternatively, use
CreateDynamicMapIcon(Ex). Valid styles range from 0 to 3, and each
map icon's default style is 0.
- Only circles and spheres may be used with the attach area natives.
- The points in CreateDynamicPolygon and CreateDynamicPolygonEx need
to be specified as a sequence of ordered pairs (x1, y1, x2, y2,
..., xn, yn). The number of elements in the array must be divisible
by two for this reason. The first point must also be equal to the
last point to form a closed path.
- The number configurable in Streamer_CellDistance is used to
determine whether or not an item needs to be put in a cell for
spatial indexing purposes. The default value is 600.0. If an item's
streaming distance (or, in the case of areas, an item's size)
exceeds that of the cell distance, it will be streamed from any
point on the map. For example, if a map icon's streaming distance
is set to 100.0, it will only be visible if the player is in the
same cell as the map icon or in an adjacent cell (assuming the
default cell distance of 600.0 has not been changed). However, if
the map icon's streaming distance is set to 1000.0, it will be
visible no matter where the player is.
- The number configurable in Streamer_CellSize is used to determine
the size of each cell in the grid. The default value is 300.0.
- Note that Streamer_CellDistance and Streamer_CellSize rebuild the
grid each time they are called, so use them only when necessary.
The default values are also considered optimal, so in most cases,
it is recommended to simply leave these natives alone unless a
specific need arises.
- Items can be grouped together using y_groups, which is part of the
YSI library.
Performance Notes
-----------------
8. - It is not recommended to use a high streaming distance for every
item. This can drastically impact performance because it leads to
more items being checked on each update. If an item's streaming
distance exceeds that of the cell distance (600.0 by default), it
also does not benefit from spatial indexing, which can lead to even
worse performance. Only set high streaming distances for items
which need to be visible from very far away (global map icons, for
example).
- Adding too many virtual worlds and interiors to items can lead to
increased memory usage and decreased performance. Specifying -1
(all virtual worlds and interiors) actually ensures the best
performance, because it eliminates the need to do a lookup when
that item is checked on each update. Note that this does not apply
to players since only a finite amount can be added.
Dependencies
------------
The Windows version requires the Microsoft .NET Framework 4.5.1 or
higher.
