The following sample includes a basic function that takes a table of objects
and parents them into a new Model, returning that Model.


Model:AddPersistentPlayer

playerInstance

This code sample demonstrates manual creation of joints on two parts that are
siblings of the script (PartA and PartB). It creates a joints on two touching
parts with compatible surface types (Studs and Inlet).


In this sample the joints in every Player character Model added will be broken
3 seconds after spawning. Breaking these joints will cause the Humanoid to
die.


Model:BreakJoints

Model:GetBoundingBox

The code sample below demonstrates how Model.GetExtentsSize can be used to get
the size of the bounding box containing the parts.


Model:GetExtentsSize

Model:GetModelCFrame

This code would create a model, put some parts in it, position them randomly,
and then print its size:


Model:GetModelSize

The following code demonstrates how GetPrimaryPartCFrame and
SetPrimaryPartCFrame can be used to rotate a model.

A simple model is created in the Workspace and a loop is started that will
rotate the model 10 degrees around the Y axis every 0.2 seconds.


Model:GetPrimaryPartCFrame

This code sample demonstrates how joints can be made using the
Model:MakeJoints function.

A model is instanced, with two parts on top of each other. The top part is
anchored and the bottom part is not. Normally, when parented to the Workspace
the bottom part would fall to the Baseplate.

However, as TopSurface property of the bottom part is set to
Enum.SurfaceType.Weld, this means that when Model:MakeJoints is ran a
connection is made between them.

Therefore the bottom part does not drop until the joints in the model are
broken. This is often done using Model:BreakJoints, but in this example the
connection is broken using an explosion.


This code sample demonstrates creation of joints on two parts that are
siblings of the script (PartA and PartB). It uses MakeJoints on two touching
parts with compatible surface types (Studs and Inlet).


Model:MakeJoints

This sample demonstrates how Model:MoveTo avoids collisions.

A simple two part Model is created, and its PrimaryPart is set. An large
obstruction part is placed next to it.

After 5 seconds Model:MoveTo is used to direct the model to move inside the
obstruction part. However, as MoveTo will not move a model inside of an
obstruction the Model is moved up on the Y axis and placed above the
obstruction.

Model:ResetOrientationToIdentity

This sample demonstrates how Model:TranslateBy ignores collisions and respects
the orientation of the model.

A simple two part Model is created, rotated 45 degrees on the Y axis, and its
PrimaryPart is set. An large obstruction part is placed next to it.

After 5 seconds Model:TranslateBy is used to direct the model to move inside
the obstruction part. The model will move inside of the obstruction and
maintain it's current orientation.

Model.LevelOfDetail

Model.ModelStreamingMode

This code sample creates and throws a dice model, then outputs whether it
landed with the blue side facing up. If `Class.Model.PrimaryPart` was not set,
the pivot / bounding box of the dice would rotate, as the parts inside of it
are physically simulated during the roll.


Model.PrimaryPart

Model.World Pivot Orientation

Model.World Pivot Position

This code sample shows a custom function for resetting the pivot of a model
back to the center of that model's bounding box.


Model.WorldPivot

This code sample is a simple teleport script that moves your character
10&nbsp;studs forwards in the direction you're currently facing when you press
the <kbd>F</kbd> key. It does so by getting the current pivot with
`Class.PVInstance:GetPivot()` and calling `PVInstance|PivotTo` to move the
character forwards.

The below example would print "Part is now a child of Model".


Instance.AncestryChanged

child

parent

Instance.AttributeChanged

attribute

This code sample demonstrates the Changed event firing within a parent object.


This sample demonstrates the subtleties of the Changed event on normal objects
and "-Value" objects.


Instance.Changed

property

This snippet prints the names of objects as they are added to the Workspace:


Instance.ChildAdded

This snippet prints the names of objects as they are removed from the
Workspace:


Instance.ChildRemoved

This following example will print the name of any object that is added to the
Workspace:


Instance.DescendantAdded

descendant

The following example prints the name of any descendant as it is being removed
from the Workspace:


Instance.DescendantRemoving

This sample demonstrates how an Instance being destroyed remains in place
until the connected function yields.


Instance.Destroying

Instance.childAdded

This example creates a Part and adds a few sparkle objects to the part. Then
it calls Part:ClearAllChildren() to remove all of the children.


Instance:ClearAllChildren

This code first references an existing object in the `original` variable.
Then, it makes a copy of the object, sets the parent to that of the original,
and finally moves the copy to (0, 50, 0).


Instance:Clone

Instance:Destroy

Instance:FindFirstAncestor

name

Instance:FindFirstAncestorOfClass

Instance:FindFirstAncestorWhichIsA

The below would look in Workspace for an object name "Brick". If found, it
will change the name of the object to "Foo".

Instance:FindFirstChildOfClass

Instance:FindFirstChildWhichIsA

Instance:FindFirstDescendant

Instance:GetActor

Instance:GetAttribute

Instance:GetAttributeChangedSignal

Instance:GetAttributes

The below would print the name of all objects currently in Workspace when ran.


Instance:GetChildren

Instance:GetDebugId

scopeLength

GetDescendants is often used to do something to all the descendants that are a
particular type of object. The code in this example uses GetDescendants and
`Class.Instance:IsA()` to find all of the parts in the workspace and turns
them green.


Instance:GetDescendants

This code sample demonstrates the behavior of `Class.Instance:GetFullName()`.
It shows how the function behaves when called on an object not in the
`DataModel` hierarchy, and it also shows how the return value does not escape
special characters.


This code sample re-implements the `Class.Instance:GetFullName()` function in
Lua.


Instance:GetFullName

This code sample demonstrates the equivalence of the `Changed` event and event
returned by `GetPropertyChangedSignal`.


This code sample demonstrates how to save a value before a changed event fires
on it in order to get more information about a change.


Instance:GetPropertyChangedSignal

Instance:IsA

Instance:IsAncestorOf

The following code demonstrates how a part can be re-added to the DataModel
after being removed:

Roblox does not replicate this member across its server-client boundary.

Lua code can’t access this member. You might be able to change its value from the property window in Roblox Studio.

This object’s replication behavior is dependent on the player who owns it.

This member is accessible only through the command bar and plugins only. Attempting to access this member from scripts causes an error.

This property is read-only and is safe to read in unsynchronized threads. Attempting to write to it causes an error.

This member is read only. Attempting to write to this member causes an error.

This member is accessible only in CoreScripts.

Only Roblox CoreScripts can access this member, and it isn’t usable by Players.

You can read and write to this property safely from multiple threads.

This class is a top-level singleton. Retrieve an instance of this class with the GetService function.

Multiple threads can potentially write to this property, so it’s unsafe to read from unsynchronized threads.

This function pauses the Lua thread that called it until it returns a result. This doesn’t interrupt other scripts.
