UIAspectRatioConstraint

Show deprecated

A UIAspectRatioConstraint ensures that the parent UI element (GuiObject) maintains a particular aspect ratio even if its size is set as a percentage of its parent. If an object with this constraint is also under the control of a UILayout such as UIGridLayout, then the constraint controls the objects size and overwrites any size the layout would apply.

When applied to a GuiObject, the UIAspectRatioConstraint will make sure that the objects ratio is maintained by the value defined in UIAspectRatioConstraint/AspectRatio. The UIAspectRatioConstraint/AspectType sets what determines the maximum size of the object. When set to UIAspectRatioConstraint/FitWithinMaxSize, the constraint will make the object the maximum size it can be within the /GuiObject of the element. When set to ScaleWithParentSize, the elements maximum size will be the size of the parent while still maintaining the aspect ratio. Finally, the UIAspectRatioConstraint/DominantAxis will determine which axis to use when setting the new size of the element.

Properties

float

AspectRatio

Determines the width-to-height ratio to be maintained by the constraint.

AspectType

AspectType

Determines what limits the maximum size of the UI element.

DominantAxis

DominantAxis

Determines the axis to use when setting the new size of the UI element.

[ReadOnly] [NotReplicated]

The cost of saving the instance using data persistence.

Instance

Parent

Determines the hierarchical parent of the Instance.

bool

RobloxLocked

If true, the Instance and its descendants cannot be indexed or edited by a Script or LocalScript and will throw an error if it is attempted.

Returns the first child of the Instance found with the given name.

Array

GetDescendants ( )

[CustomLuaState]

Returns an array containing all of the descendants of the instance

Objects

GetChildren ( )

Returns an array containing all of the Instance's children.

void

Destroy ( )

FindFirstChildWhichIsA ( string className , bool recursive )

Returns the first child of the Instance for whom Instance/IsA returns true for the given className.

bool

IsAncestorOf ( Instance descendant )

Returns true if an Instance is an ancestor of the given descendant.

bool

IsDescendantOf ( Instance ancestor )
