Re: Release of Enigma 1.30-alpha

A mouse event with so large numbers is discarded by Enigma on purpose, because the black ball would suddenly be subjected to an enormous impulse, if the mouse event would have been interpreted the normal way. So, the ball not moving is a logical and necessary consequence to an overly large mouse xrel/yrel-pairing. So ... we have to ask: Why does SDL2 report so large xrel/yrel-values?

I cannot reproduce the bug ... could you please answer the following questions?

Do you use a special kind of mouse or mouse port?

Do you use an intermediary program (like a logger) or a remote desktop? (Those might manipulate the mouse coordinates. The fact that you observe the same problem using VirtualBox can be explained by (1) VirtualBox manipulating the mouse coordinates or (2) the host OS being involved in the bug.)

Were there other windows on the screen, besides Enigma's window?

There is a bug report about SDL 2 here concerning "jumpy" relative mouse motion:
It needs other windows other than Enigma to be present. It should be closed on X11, but your host OS might still be reporting wrong numbers. However, the numbers you report are so much larger, that it just doesn't make sense, unless you use something like a 40.000 x 20.000 pixel display?

I tried installing on Ubuntu 20.04 based Linux Mint Mate and got the same
problem with the mouse while in the level.

At this point the only point of difference I see is that I'm running it on a
VirtualBox virtual machine.

In other news, I've built and uploaded a macOS dmg that anyone can use to
install Enigma on macOS without having to have Homebrew and without building
from source. So far it has only been tested on macOS Catalina. If it doesn't
work on High Sierra or Mojave, let me know and I can build it on a High Sierra
machine instead, which should be forward-compatible to Mojave and Catalina.
Big Sur will have to wait until I can set up a machine to play with it.
