Specification
This function's behavior is dependent upon the VM the script is using. Mono is the new VM, LSO is the old VM.
- Mono
- Sets the memory limit for the script.
- The memory limit can be set up to 64k.
- The memory limit can not be set lower than the memory currently in use by the script.
- All new scripts start with a limit of 64k
- Mono scripts compiled before this function was introduced continue to use the 64k limit.
- A lower limit will effect the amount of memory reported in the viewer UI and by llGetObjectDetails.
- The memory limit is not the amount of real memory actually used by the script, just the upper limit on it.
- LSO
- Has no effect on LSO scripts which will always use exactly 16k
Caveats
- Mono
- When n is too small, llSetMemoryLimit(n) is ignored and the memory limit is not changed
Examples
// Memory-walkthrough by Daemonika Nightfire (daemonika.nightfire)
integer limit = 20000; // <- bytes
Test()
{
llSetText("Limited Memory " + (string)llGetMemoryLimit() +
"\nUsed Memory " + (string)llGetUsedMemory() +
"\nFree Memory " + (string)llGetFreeMemory(),<1,1,1>,1);
}
default
{
state_entry()
{
llSetMemoryLimit(limit);
llScriptProfiler(PROFILE_SCRIPT_MEMORY);
Test();
llScriptProfiler(PROFILE_NONE);
llSay(0,"This script used at most " + (string)llGetSPMaxMemory() + " bytes of memory during Test.");
}
}
// Result:
// Floating Text:
// Limited Memory 20000
// Used Memory 4972
// Free Memory 15100
// Chat:
// [05:11] Object: This script used at most 4972 bytes of memory during Test.
