Pretty Speedometer [stebler]

[Vega]

Due to recent demand on Discord and DMs, here is a customizable XYZ/XZ configuration of Version 1.1

V = Velocity Config (0 = XYZ Speed, 1 = XZ Speed)
XXXX = Widescreen X Position
xxxx = 4:3 X Position
YYYY = Y Position
WWWW = Scale (use 3F80 if unsure)
r = Number of Decimals
tt = Text Config (00 = omit km/h text, 20 = km/h text to right, 0A = km/h text underneath)
kk = Color (30 = Yellow, 31 = Blue, 32 = Red, 33 = Green, 34 = White)

X,x, Y, and W values are left-half single precision float values. (i.e. 3F80 = 3F800000 = 1)

Example XXXX xxxx YYYY values:
Bottom Right, kmh underneath - 42F0 41F0 C35C
Bottom Left, kmh underneath - C3FA C3CD C35C
Bottom Left, kmh to right - C3FA C3CD C36E
