SetMouseDelay

Sets the delay that will occur after each mouse movement or click.

SetMouseDelay, Delay , Play

Parameters

Delay

Time in milliseconds, which can be an expression. Specify -1 for no delay at all or 0 for the smallest possible delay (however, if the Play parameter is present, both 0 and -1 produce no delay).

Play [v1.0.43+]

If blank or omitted, the delay is applied to the traditional SendEvent mode. Otherwise, specify the word Play to apply the delay to the SendPlay mode. If a script never uses this parameter, the delay is always -1 for SendPlay.

Remarks

If SetMouseDelay is not used, the default delay is 10 for the traditional SendEvent mode and -1 for SendPlay mode.

A short delay (sleep) is done automatically after every mouse movement or click generated by Click, MouseMove, MouseClick, and MouseClickDrag (except for SendInput mode). This is done to improve the reliability of scripts because a window sometimes can't keep up with a rapid flood of mouse events.

Due to the granularity of the OS's time-keeping system, delays might be rounded up to the nearest multiple of 10 or 15. For example, a delay between 1 and 10 (inclusive) is equivalent to 10 or 15 on most Windows XP systems (and probably 2k).

A delay of 0 internally executes a Sleep(0), which yields the remainder of the script's timeslice to any other process that may need it. If there is none, Sleep(0) will not sleep at all. By contrast, a delay of -1 will never sleep.

The built-in variable A_MouseDelay contains the current setting for Send/SendEvent mode. [v1.1.23+]: A_MouseDelayPlay contains the current setting for SendPlay mode.

Every newly launched thread (such as a hotkey, custom menu item, or timed subroutine) starts off fresh with the default setting for this command. That default may be changed by using this command in the auto-execute section (top part of the script).
