No idea what to call it, but simply put, just like a spring but instead of the springy motion, it’s just a linear motion with 3 options: position, target, and speed
This is what I have right now, but theres stuttering once it reaches its target it seems like, and stuff gets glitchy at high speeds. My goal is to allow it to work with vectors at the same time too, so the position and target could be either numbers or vector3s.
local line = {}
local tick = tick
local clamp = math.clamp
local sign = math.sign
local inf = math.huge
– a + ((b - a) * c)
function line.new(init)
local t0 = tick()
local speed = 1
local target = init and init * 0 or 0
local position = init or 0
local function update(time)
local dt = time - t0
local dist = target - position
position = position + speed * dt * sign(target - position)
t0 = time
end
return setmetatable({},{
__index = function(_, index)
local time = tick()
if index == 'p' then
update(time)
return position
elseif index == 't' then
return target
elseif index == 's' then
return speed
end
end,
__newindex = function(_, index, value)
local time = tick()
if index == 'p' then
position = value
update(time)
elseif index == 't' then
target = value
update(time)
elseif index == 's' then
speed = value
update(time)
end
end
})
end
return line
any help is appreciated
