Arguments

• int x - X coordinate in the screen space.
• int width - Window width.
• int border_x - Horizontal border size.

Return value

The given X coordinate if the window is visible; otherwise, the X coordinate, at which the window will be visible.

int engine.interface.getVisiblePositionY (int y, int height, int border_y)
