<User:SwissalpS> Some more comments explaining what the convert function is about and why it is needed, would make understanding the formulas like "v*2*15/13*0.35" better.
<User:Huhhila> That particular formula is taken from https://minetest.gitlab.io/minetest/formspec/#migrating-to-real-coordinates and results in the following:
converted = {
{
command = "set",
height = 10.5,
real_coordinates = true,
locked = true,
width = 13
},
{
command = "clear"
},
{
label = "X+",
X = 0.375,
command = "add",
W = 4,
Y = 0.375,
name = "xplus",
H = 0.80769230769231,
element = "button_exit"
},
{
label = "X-",
X = 0.375,
command = "add",
W = 4,
Y = 1.625,
name = "xminus",
H = 0.80769230769231,
element = "button_exit"
},
{
label = "Y+",
X = 0.375,
command = "add",
W = 4,
Y = 2.875,
name = "yplus",
H = 0.80769230769231,

},

For example code related to jumpdrive digiline control such conversion is somewhat offtopic, and should be moved to another more touchscreen-focused page. But @User:BuckarooBanzai, was the original layout of the UI significant / does preserving it matter?
