Dialog-information.png This article needs checking.

Reason(s):

isInsideRadarArea() does not work correctly.
Use something like this instead:

function isReallyInsideRadarArea ( theArea, x, y )
    local posX, posY = getElementPosition ( theArea )
    local sizeX, sizeY = getRadarAreaSize ( theArea )
    return (x >= posX) and (x <= posX + sizeX) and (y >= posY) and (y <= posY + sizeY) 
end
isInsideRadarArea = nil


This function checks if a 2D position is inside a radararea or not.

Syntax

bool isInsideRadarArea ( radararea theArea, float posX, float posY )

Required Arguments

  • theArea: The radar area you're checking the position against.
  • posX: The X coordinate of the position you're checking.
  • posY: The Y coordinate of the position you're checking.

Returns

Returns true if the position is inside the radar area, false if it isn't or if any parameters are invalid.

Example

This function checks if an element is within a radar area.

function isElementInsideRadarArea ( theElement, theArea )
	-- get the x, y coordinates from getElementPosition (z gets silently discarded)
	local posX, posY = getElementPosition( theElement )
	-- call isInsideRadarArea with those coordinates and return its result
	return isInsideRadarArea ( theArea, posX, posY )
end
