How would I go about manipulating a rotated part on the global X-Axis with Tweens (or CFrame)?

Asked 254 views1 answers

Background

Okay, that may have been very hard to understand, allow me to reiterate.

So I have a bundle of parts that are all anchored, in a specific group. I am currently iterating through them all in a for loop. There are no problems with the loop or anything, just my code that I actually use to move it.

I am using TweenService to smoothly move these parts. If it helps, I am using the method of creating a TweenInfo, creating a Tween, and then playing it at a select time.

The Problem

The issue starts to occur with the third argument of my Tween. I put in the instance to tween, the information used to tween, and for my table, the target CFrame of the part. The only problem, is that how do I go about moving it upwards by 100 studs, while it is rotated? Do I use CFrame? Should I multiply or equal it? And most importantly, how can I move it on the global Y-Axis, no matter it's rotation? Also, I know that this probably has something to do with :ToGlobalAxis() (or whatever the function is), but I don't know how to use it.

My Code

local tweenService = game:GetService("TweenService")

local train = script.Parent
local cars = train.Modeling:GetChildren()

local tweenInformation = TweenInfo.new(
	10,
	Enum.EasingStyle.Circular,
	Enum.EasingDirection.In,
	0,
	false,
	0
)

for i,v in next,cars do
	for x,y in next,v:GetChildren() do
		tweenService:Create(y,tweenInformation,{CFrame = CFrame.new(0,100,0)}):Play() --
Only moves it on the part's Y-Axis, not the global Y-Axis.
	end
end

Any help would be appreciated!

If you want to tween a model then you have to weld every part of the model to the primary part of the model and then u tween the primarypart not tween every part of a model. and if you want to just move a part 100 studs higher then ur fine with Position (which is a Vector3)

Example in this case

local tweenService = game:GetService("TweenService")

local train = script.Parent
local cars = train.Modeling:GetChildren() -- each car his parts are welded to the primary part,

local tweenInformation = TweenInfo.new(
    10,
    Enum.EasingStyle.Circular,
    Enum.EasingDirection.In,
    0,
    false,
    0
)

for _, car in pairs(cars) do -- car is a model with a PrimaryPart
        tweenService:Create(car.PrimaryPart,tweenInformation,{Position = car.PrimaryPart.Position + Vector3.new(0,100,0)}):Play() -- using the old position i can make every car go 100 studs higher on Y than its previous position
end

btw there are plugins for welding each part in a model to another part

If these are just random parts inside each other than you can do

local tweenService = game:GetService("TweenService")

local train = script.Parent
local cars = train.Modeling:GetChildren()

local tweenInformation = TweenInfo.new(
    10,
    Enum.EasingStyle.Circular,
    Enum.EasingDirection.In,
    0,
    false,
    0
)

for i,v in next,cars do
    for x,y in next,v:GetChildren() do
        tweenService:Create(y,tweenInformation,{Position = y.Position + Vector3.new(0,100,0)}):Play() -- moves the part 100 studs higher on the Y axis 
    end
end
