Description

Description:
safezone.jpg

Returns the height of the screen in screen measurement units. Taken from top left corner of the default viewport (0,0) of the screen and going in the same direction as the Y axis, the value will be positive but resulting Y will end up beyond the bottom border. Therefore in order to calculate Y of the bottom screen border, the length of safeZoneY must be subtracted from safeZoneH, but because it is negative, it must be added instead.

_screenBottomBorderY = safeZoneH + safeZoneY. The measurement units depend on the current screen resolution getResolution. See also SafeZone.

Syntax

Syntax:
safeZoneH
Return Value:
Number - height of the screen in screen measurement units

Examples

Example 1:
_screenHeight = safeZoneH;
Example 2:
_screenTopBorderY = safeZoneY; _screenBottomBorderY = safeZoneH + safeZoneY;
Example 3:
Create control 50% wide, 30% tall, centered on screen:
private _ctrl = findDisplay 46 createDisplay "RscDisplayEmpty" ctrlCreate ["RscText", -1]; _ctrl ctrlSetBackgroundColor [1,0,0,0.5]; private _ctrlWidth = 0.5 * safeZoneW; // 50% of screen width private _ctrlHeight = 0.3 * safeZoneH; // 30% of screen height _ctrl ctrlSetPositionW _ctrlWidth; _ctrl ctrlSetPositionH _ctrlHeight; _ctrl ctrlSetPositionX ((safeZoneW - _ctrlWidth) / 2 + safeZoneX); // center it horizontally _ctrl ctrlSetPositionY ((safeZoneH - _ctrlHeight) / 2 + safeZoneY); // center it vertically _ctrl ctrlCommit 0;
