Game versions1.20.1–26.2

1.0.0.3

Version id with suffix 'a' means it works like cs series or Apex while 'b' means it's original idea. I'll update both when new mc version release. Chose the version on your own.

1.0.0.2

make the sensitivity procedule same as counterStrike2

1.0.0.1 or below

the dpi range provided by the mouse is going higher and higher, the origin mouse sensitivity procedure is not working cool when u set dpi to value like 20000. this mod only do one simple thing: multiply the origin mouse sensitivity by itself when processing

Original Code:

Double value = that.client.options.getMouseSensitivity().getValue();
double d = value * 0.6F + 0.2F;
double e = d * d * d;
double f = e * 8.0;
i = that.cursorDeltaX * f;
j = that.cursorDeltaY * f;

Modified Code:

for versionID with suffix b

Double value = that.client.options.getMouseSensitivity().getValue();
double d = value * 0.6F + 0.2F;
double e = d * d * d * value; // Multiply e by mouseSensitivity
double f = e * 8.0;
i = that.cursorDeltaX * f;
j = that.cursorDeltaY * f;

for versionID with suffix a somehow make it finnally same as cs2 which is 0.022 * cursorDeltaX|Y

The variables i and j are ultimately added to your look direction. f is used for non-spyglass views, while e is used for spyglass views.
