The question says it all, how would I force MouseLock upon the player, or at least simulate it?
To avoid confusion, I'll make it clear that I want to force the option that EnableMouseLockOption in StarterPlayer enables.
For example, if you go in ROBLOX Client Settings, you'll see Enable Shift Lock Switch, I want to force that.
And please, no GUIs.
