In the future, could we possibly have a function called math.movetowards(current, target, maxDelta)?
It would behave like this:
local function moveTowards(current, target, maxDelta)
if current < target then
return math.min(target,current + maxDelta)
elseif current > target then
return math.max(target,current - maxDelta)
I use this function a lot in my code, mostly in heartbeat threads for doing visual transitions between states.
It would be handy to have something like it built-in.
