Lua Scripting, Linear interpolation (Lerp, InverseLerp, Remap) - YouTube
Code made in the tutorial:
-- Domain: t[0->1]
-- Range: [a->b]
local function lerp(a, b, t)
return a + (b-a) * t
end
-- Domain: x[a->b]
-- Range: [0->1]
local function inverseLerp(a, b, x)
return (x-a)/(b-a)
end
-- Domain: [in1 -> in2], t[0->1]
-- Range: [out1 -> out2]
local function remap(in1, in2, out1, out2, x)
return lerp(out1, out2, inverseLerp(in1, in2, x))
end
-- Real world example
local slider = {0, 100}
local sliderValue = 50
local playerSpeed = {16, 64}
print(remap(slider[1], slider[2], playerSpeed[1], playerSpeed[2], sliderValue))
