setfflag

Writes a new value to a Roblox Fast Flag.

setfflag(name: string, value: string): ()

Pass the flag’s literal name, without a prefix (e.g. "EnablePreloading", not "DFFlagEnablePreloading").

Flag names follow one of six type prefixes: FFlag / DFFlag (booleans), FInt / DFInt (integers), FString / DFString (strings). The leading D marks dynamic flags, which refresh at runtime; the rest lock at session start.

value is always passed as a string, regardless of the flag’s declared type.

Parameters

Parameter	Type	Description
name	string	Flag name.
value	string	E.g. "60" for an FInt, "true" for an FFlag.

Returns

void
