| + | #Redirect [[Scripting Documentation]] |
| − | An important ingredience in Second Life is scripting. It is the engine that drives it all.<br />
| + | |
| − | In SL [http://wiki.secondlife.com/wiki/LSL_Portal LSL (Linden Scripting Language)] is the language you have to use. This language has its limitations, and is executed very slowly. But nevertheless it works and it gets the job done.<br />
| + | |

| − | Linden Labs are planning to move LSL scripting over to C# on Mono some time in the future. This has been in the works since 2005 at least. There are many difficult technical challenges related to this.<br />

| − | OpenSim supports LSL and C# scripts. But with limitations:<br />
| + | |
| − | * Not all commands and events has been implemented. See [[llFunction implementation status]] for details on what commands work and not.
| + | |
| − | * Scripts that are running can not cross regions.
| + | |
| − | * You can not use loops inside your scripts. Actually you can use loops, but it will block other scripts from executing.
| + | |
| − | <br />
| + | |
| − | The OpenSim script engine compiles the LSL code down to .Net code that is JIT'ed to CPU native gode. In effect this means that a LSL script in OpenSim performing pure mathematical functions will have speed close to a C++ program. Of course normally you don't do much math, but still speed should be ok.<br />

| − | The ScriptEngine is being developed by many developers. If you want to contribute, have a look at the [[OpenSim.Region.ScriptEngine]] page.<br />
| + | |
| − | A blog with development status can be found at [http://teddmaa.blogspot.com/ http://teddmaa.blogspot.com/].<br />

| − | | + | |
| − | Have a look at the [http://wiki.secondlife.com/wiki/LSL_Portal LSL wiki] to learn LSL.<br />

| − | The current procedure to get a script working in OpenSim is:
| + | |
| − | * Create a new script in inventory.
| + | |
| − | * Write whatever script you want there. Check [[llFunction implementation status]] for what commands that is supported.
| + | |
| − | * Drag the script over to an object.
| + | |
| − | * Delete the script from the object to deactivate script.
| + | |
| − | <br />
| + | |
| − | There are still some defects:
| + | |
| − | * You can not edit script while it is inside object.
| + | |
| − | * When restarting OpenSim server scripts are lost and not started.
| + | |
| − | * Line numbers in error messages may miss by 1 or 2 lines.
