gratis – Autoclicker that moves mouse using relative coordinates

I need to place objects in a map. They are a lot but distributed regularly (zig-zag).

I need an “auto-clicker” that can repeatedly:

• click
• move mouse of +5 pixels on y axis
• click
• move mouse of +3 pixels on x axis and -5 on y axis
• click
• repeat for n times

It should be Open Source, or free with a “clean” installer.

Most auto-clickers I’ve seen use absolute screen positions, I don’t need that.

If you can suggest a more complex program for macros, that’s fine (as long as the above requirements are satisfied).

I tried Auto Mouse Clicker, Move Mouse, MouseBot, AutoMouser and looked at the screenshots of some others.

Thanks.
