Mouse

A Mouse class object is an object that grants access to a player's mouse and keyboard. This object is only active when a tool is selected and will disconnect all connections to itself when or if a player de-selects their Tool or HopperBin that was using the object.

While active, scripts can detect keys pressed, mouse button selection, and the mouse's current target and where it hit in the Workspace.

Currently, there is no way to get a player's mouse without a tool. You can, however, get the player's mouse by placing a tool with a handle inside of the player's character. This will grant almost imediate access to the player's mouse.
