PluginMouse

Inherits from: Mouse → Instance → Object

The PluginMouse object gives Plugins access to the mouse. It works like the Mouse object and can be obtained using the plugin Plugin:GetMouse() method.

Note the PluginMouse can only be used when the plugin has been activated using Plugin:Activate().

In addition to the functions from the Mouse object, the PluginMouse includes the PluginMouse.DragEnter function which keeps track of items being selected while the mouse is dragging.

For more information on how to use mouse objects, see the Mouse page.
