RandomBezier help

[KramtauDesra]

Hello everyone, so I stumbled upon this ahk command called "RandomBezier", it seemed really helpful, but I just could not find anything on how exactly to use it? I've seen some examples of it, but like I can't find anything on what stuff like "T" time A_Space "P3-5" means in it, if anyone could explain it to me, I would be very helpful, thank you.

It's surely no AHK command - but some kind of user-defined function, and there might be different versions of it.
That's why you should link to where you found it - so that people can take a look at the code. Everything else will take a crystal ball, or at least additional work for potential helpers...

[KramtauDesra]

oh, that makes sense, I orignally found it here: https://autohotkey.com/board/topic/85043-randombezier-move-the-mouse-through-a-random-bezier-path/

[gregster]

The github link there (https://github.com/MasterFocus/AutoHotkey/tree/master/Functions/RandomBezier) provides an example (and a "usage" file).
Did you try it ? It works for me.

About the T option:

"Tx" (where x is a positive number)
> The time of the mouse movement, in miliseconds
> Defaults to 200 if not present

About the P option:

# "Px" or "Py-z" (where x, y and z are positive numbers)
> "Px" uses exactly 'x' control points
> "Py-z" uses a random number of points (from 'y' to 'z', inclusive)
> Specifying 1 anywhere will be replaced by 2 instead
> Specifying a number greater than 19 anywhere will be replaced by 19
> Defaults to "P2-5"

[KramtauDesra]

Oh, no I haven't, I checked them out and the files don't seem to talk about the "time" function, also this might be a stupid question, but how do I even get it so I can use it in my files?

[KramtauDesra]

sorry for the reply with no time usage, it only showed for me that you explained it after I replied

[gregster]

You should start with the example, and try it - then play with it, and look at the 'Usage' file which explains the options.

[KramtauDesra]

Yes, but didn't you mention this was like some kind of an addon or something? If it isn't in ahk originally, then somehow I need to get it I assume?

The file RandomBezier.ahk (https://github.com/MasterFocus/AutoHotkey/blob/master/Functions/RandomBezier/RandomBezier.ahk) contains the function:

You can copy it into your own files - or save it as a separate ahk-file and then #include it in your main script file (like the github example does):

Code: Select all

; 30/May/2013 03:00h BRT

#Include RandomBezier.ahk

F5:: ToolTip, % "Points: " RandomBezier( 0, 0, 400, 400, "T500 RO RD OT0 OB0 OL0 OR0 P4-20" )
F6:: ToolTip, % "Points: " RandomBezier( 0, 0, 200, 200, "T1000 RO RD")
F7:: ToolTip, % "Points: " RandomBezier( 0, 0, 150, 150, "T1500 RO RD OT150 OB150 OL150 OR150 P6-4" )
F8:: ToolTip, % "Points: " RandomBezier( 0, 0, 200, 0, "T1200 RO RD OT100 OB-100 OL0 OR0 P4-3" )

F9:: ToolTip, % "Points: " RandomBezier( 0, 0, 400, 300, "T1000 RO P5" )
F10:: ToolTip, % "Points: " RandomBezier( 400, 300, 0, 0, "T1000 RD" )

F12::RELOAD
ESC::EXITAPP

Then you can call the function like shown above. Of course, you can remove the Tooltip part, if you don't need/want it:

Code: Select all

RandomBezier( 0, 0, 200, 200, "T1000 RO RD")

Thank you so much

[KramtauDesra]

Hello, me again, sorry for bothering, but I seem to get this error while trying to include it, am I suppost to have it in a specific location? #Include file RandomBezier.ahk cannot be opened

[gregster]

Easiest way is to save RandomBezier.ahk in the same directory like your main script, then #Include RandomBezier.ahk .
Or you add a path (see https://www.autohotkey.com/docs/commands/_Include.htm)

[KramtauDesra]

Thanks!
