• void HudSetVirtualSize(fixed width, fixed height)

Sets the HUD Library's HUD coordinate system size. Default is 640×480. After that, actual screen boundaries in HUD coordinate system for current aspect ratio can be retrieved using the following functions:

• fixed HudX1() or fixed HudLeft() – left boundary
• fixed HudX2() or fixed HudRight() – right boundary
• fixed HudY1() or fixed HudTop() – top boundary
• fixed HudY2() or fixed HudBottom() – bottom boundary

Example:

// draw this item in the upper left corner of the screen
// uses 640x480 HUD coordinate system
DRAW_ITEM(HudTop(), HudLeft());

Screen boundaries can be calculated for any HUD coordinate system size without calling HudSetVirtualSize:

• fixed HudX1For(fixed width) or fixed HudLeftFor(fixed width) – left boundary for given HUD coordinate system width.
• fixed HudX2For(fixed width) or fixed HudRightFor(fixed width) – right boundary for given HUD coordinate system width.
• fixed HudY1For(fixed height) or fixed HudTopFor(fixed height) – top boundary for given HUD coordinate system height.
• fixed HudY2For(fixed height) or fixed HudBottomFor(fixed height) – bottom boundary for given HUD coordinate system height.
