[edit] Scripting Languages
OpenSimulator currently supports 2 scripting languages (LSL and C#). The others listed here are no longer supported or may only work on some platforms.
Scripts are restored automatically when OpenSimulator starts.
[edit] LSL
LSLv2 is the well known Second Life scripting language. It is basically a C#/Java-like language. The majority of ll-functions have been implemented and it is possible to make usable scripts comparable to SL. Although LSL (including OSSL and Mod* functions where enabled) is the default, if for any reason you want to ensure that the compiler treats your script as LSL you should have "//lsl" in a comment in the first line of the script. For a particular script engine, you can also specify //XEngine:lsl or //YEngine:lsl (caution: YEngine is still considered experimental in OpenSim 0.9.1.0 "Snail" release!) Example code:
default
{
state_entry()
{
llSay(0, "This is an incredibly useless program.");
}
}
[edit] C#
C# is a .Net language.
Although it is C# the behaviour is much like LSL in the sense that you still use ll-functions like llSay(), and still use the same events as in LSL.
The first line of your script must be the comment "//c#" for the compiler to treat it as C#. You can also specify //XEngine:c# but at present you will find that YEngine does not support C# as of OpenSim 0.9.1.0 "Snail" release.
Example code:
//c#
public void default_event_state_entry()
{
llSay(0, "This is an incredibly useless program.");
}
You also need AllowedCompilers = lsl, c# under [XEngine] to make this work.
[edit] VB.Net
Mono does not have compiler for VB.Net, so VB.Net scripts may not work on Mono. :)
VB.Net is a .Net language.
Although it is VB.Net the behaviour is much like LSL in the sense that you still use ll-functions like llSay(), and still use the same events as in LSL.
The first line of your script must be the comment "//vb" for the compiler to treat it as VB.NET. You can also specify //XEngine:vb but at present you will find that YEngine does not support VB.NET as of OpenSim 0.9.1.0 "Snail" release.
Example code:
//vb
Public Sub default_event_state_entry()
llSay(0, "This is an incredibly useless program.")
End Sub
You need AllowedCompilers = lsl, vb under [XEngine] to make this work.
If your server runs on Windows, do consider that any VB.NET scripts that an avatar were using would fail at present on a Hypergrid teleport to a grid running Mono, i.e. Linux/Unix/BSD etc.
[edit] JScript.Net
Javascript has not been present in OpenSimulator for a very long time (probably pre 0.6.6), as the required components are no longer supported upstream
The first line of your script must be the comment "//js" for the compiler to treat it as JScript.NET. However, JScript.NET support has been commented out in the code for some time. You'd need to do some serious work to fix it. You could theoretically specify //XEngine:js though presumably YEngine would not support JScript.NET as of OpenSim 0.9.1.0 "Snail" release even if the previous code were fixed?
Example code:
//js
function default_event_state_entry()
{
llSay(0, "This is an incredibly useless program.");
}
If this were one day functional again, you would theoretically require AllowedCompilers = lsl, js under [XEngine] to make this work. But it doesn't work and simply throws an error. Presumably you would be using this entirely at your own risk and more than likely would need to write the code to make it work.
[edit] Yield Prolog
Yield Prolog support has apparently not been in place for many versions.
The first line of your script would theoretically be the comment "//yp" for the compiler to treat it as Yield Prolog, or you could specify //XEngine:yp - however, at present you will find that neither XEngine nor YEngine supports Yield Prolog as of OpenSim 0.9.1.0 "Snail" release and it seems unlikely that it will be supported again.
Example code:
//yp
You would theoretically require AllowedCompilers = lsl, yp under [XEngine] to make this work. But it doesn't work and simply throws an error. Presumably you would be using this entirely at your own risk and more than likely would need to write the code to make it work.
