KeyDown

Deprecated

Mouse events have been superseded by UserInputService which should be used in all new work.

Unsafe

For thread safety, this property is not safe to read in an unsynchronized thread.

Event of:

Mouse

Description:

This event fires when a Key is pressed, with the passed argument being the key that was pressed.

Notes

Not all keys generate this event. However, you can get around this with a few of the keys, “/” for example, by using the Mouse/KeyUp event.
Some keys generate the same string as other keys.
It’s possible for the string to be empty (possibly due to “\0” key code).

Parameters

Name	Type	Default	Description
Name key	Type string	Default	Summary

Code Samples

Mouse.KeyDown

The below example, assuming that ‘mouse’ was defined, would print the key that was pressed (e.g. “q”) along with the ascii value for that key (e.g. 113).

			
				Mouse.KeyDown

				Expected Output
			
				Expand
				
			local function onKeyDown( key )
    print("Key:", key, " Code:", string.byte(key))
end
mouse.KeyDown:Connect(onKeyDown)
