If you're using a linux based server or hosting service, such as Volt-Host for example, you will need to change 'streamer.dll' to 'streamer.so'. Also, make sure you check your server log, it may give valuable information as to why your objects aren't loading, it may be an outdated include, plugin error etc. Also, check your CreateDynamicObject functions, and make sure you have the proper values for each parameter.
Код:
CreateDynamicObject(modelid, Float:x, Float:y, Float:z, Float:rx, Float:ry, Float:rz, worldid = -1, interiorid = -1, playerid = -1, Float:streamdistance = 200.0);
As you can see, this function has interior, worldid, playerid parameters, unlike the CreateObject function. Make sure you have -1 in these parameters, so the objects show in all interiors and virtual worlds for all players. (Unless you are counting on doing otherwise)
Also, read this topic for any further information on any errors you may get, and syntax for streamer functions:
