I’m trying to subtract by 0.1 when it reaches 0 it outputs some crazy number then it goes to -0.01. I’m kinda confused.
if cameraOffsetOrient > e or leaning == nil then
if leaning == nil and e ~= 0 then
e -= 0.1
else
e += 0.1
end
end
This is known as a floating-point error, it happens in all programming languages that use floats to store number values.
Heres a link that explains it pretty well, its written for Python but the same applies to most programming languages (including Lua, just pretend its saying “Lua” instead of “Python”)
Edit: You also shouldn’t worry about this, it’s likely never going to be an issue as the error is extremely small.
A little more info:
-1.5e-15 is scientific notation - like -1.5 x 10^-15 or -0.0000000000000015.
You shouldn’t compare numbers with == unless you swear they’re always integers.
Use < and > instead. For instance, use the difference to check if two numbers are close:
if math.abs(x - y) < .001 then
-- they’re close
end
