this game object will be responsible for controlling UI the size of the control. Select the UI Root (2D) object in the Hierarchy View and view the components on this game object in the Inspector view. as shown in 1-5.

qscaling Style : can be used to modify ui zoom style of the control.

Tip: This property has 3 Optional Parameters: Pixelperfect , fixedsize and the Fixedsizeonmobiles .

2 Pixelperfect, will ensure thatUIcontrol always retains the specified pixel size, regardless of the game resolution. For example, specify a pixel size of -x $, then the game in thex -the resolution, thisUIthe control will be very large, and the1920x1080x thethe resolution, thisUIThe control will be very small.

2fixedsize the Span style= "line-height:1.5" >ui control regardless of the game resolution, Always keep the specified size ratio in the game view. That is ui The control is scaled proportionally as the game view is scaled.

2fixedsizeonmobiles You will ensure that the ui controls, Keep the specified size ratio while on the mobile device, and keep the specified pixel size when on other devices.

qmanual height : when ui control's zoom style is fixedsize ui Whether the control requires proportional scaling. For example, when the height of the game view is greater than the value set by this property, ui controls are scaled proportionally, and when the height is less than this value, the ui

hint: ui When the control is scaled, the control's aspect ratio is constant.

qminimum height : when ui control's zoom style is pixelperfect ui The control will be actively scaled down;

qmaximum height : when ui control's zoom style is pixelperfect ui The control will be actively scaled up;

Tip: The resolution scale of the game view is varied and UI The control only determines whether the control is scaled based on its height, so it is possible to cause a different game resolution scale to appear UI control may be "clipped" by the view. In order to cope with this situation, it is recommended that readers use two methods to avoid it.

method One: the UI control is set to square, i.e. UI the width and height of the control are the same;

method Two: Specify the resolution scale of the game for the game view. The specified method is to Click edit| in Unity Project settings| The Player command pops up A dialog boxnamed Playersettings, as shown in1-6 .
