A while ago, I started to work on a plug-in called Color+, then I ran into an issue where it would barely run due to a dependency on the mouse, and the mouse has to be active on a plugin to use. I pretty much gave up on it, then today I decided to try to use the UserInputService and the Camera to fix this issue. So, I present the MouseModule.
Note: This is more for plug-ins rather than LocalScripts due to the nature that the UserInputService ignores the TopBar for Mouse.X and Mouse.Y positions.
For using in a plug-in, you can just replace any code like this:
local Mouse = Plugin:GetMouse()for…
local Mouse = require(script.MouseModule)Included functionality:
Included:
-Mouse.X
-Mouse.Y
-Mouse.ViewSizeX
-Mouse.ViewSizeY
-Mouse.Hit
-Mouse.Target
-Mouse.TargetSurface
-Mouse.TargetFilter (Bonus: Accepts a single instance, nil, or a table of instances!)
-Mouse.Origin
-Mouse.UnitRay
-Mouse.Button1Down ()
-Mouse.Button1Up ()
-Mouse.Button2Down ()
-Mouse.Button2Up ()
-Mouse.WheelForward ()
-Mouse.WheelBackward ()
Not included functionality:
-Mouse.Icon
-Mouse.Idle ()
-Mouse.Move ()
-Mouse.KeyDown (Key) [Deprecated, use UserInputService]
-Mouse.KeyUp (Key) [Deprecated, use UserInputService]
Hopefully some people will find more uses for this, and (possibly) add this to qCmdUt, I know people are annoyed with the deactivation.
