OOP Syntax Help! I don't understand this!

Method: RadarArea(...)


Required Arguments

  • startPosX: A float representing the origin 'x' position of the radar area.
  • startPosY: A float representing the origin 'y' position of the radar area.
  • sizeX: A float representing the width of the radar area.
  • sizeY: A float representing the height of the radar area.

Optional Arguments

NOTE: When using optional arguments, you might need to supply all arguments before the one you wish to use. For more information on optional arguments, see optional arguments.

  • r: An integer representing the amount of red in the color. Maximum value is 255
  • g: An integer representing the amount of green in the color. Maximum value is 255
  • b: An integer representing the amount of blue in the color. Maximum value is 255
  • a: An integer representing the amount of alpha in the color. This allows setting the transparency of the radar area. 255 is opaque and 0 is transparent.
  • visibleTo: An element that you wish to restrict the visibility of the radar area to. (Server function only)

Example

Click to collapse [-]
Server

This example creates a radar area for the King of the hill script, and a colsquare. When the player enters the radar area it flashes, and stops flashing when a player leaves it. 

-- create our hill area for our gamemode
local hillArea = createColRectangle ( -2171.0678710938, 678.17950439453, 15, 15 )
local hillRadar = createRadarArea ( -2183.5678710938, 705.67950439453, 40, -40, 0, 255, 0, 175 )

-- add hill_Enter as a handler for when a player enters the hill area
function hill_Enter ( thePlayer, matchingDimension )
        -- announce to everyone that the player entered the hill
        if (getElementType(thePlayer) == "player") then
                outputChatBox( getPlayerName(thePlayer) .. " entered the zone!", root, 255, 255, 109 )
                setRadarAreaFlashing ( hillRadar, true )
        end
end
addEventHandler ( "onColShapeHit", hillArea, hill_Enter )

-- add hill_Enter as a handler for when a player leaves the hill area
function hill_Exit ( thePlayer, matchingDimension )
        -- check if the player is not dead
        if (getElementType(thePlayer) == "player") then
                if isPedDead ( thePlayer ) ~= true then
                        -- if he was alive, announce to everyone that the player has left the hill
                        outputChatBox ( getPlayerName(thePlayer) .. " left the zone!", root, 255, 255, 109 )
                        setRadarAreaFlashing ( hillRadar, false )
                end
        end
end
addEventHandler ( "onColShapeLeave", hillArea, hill_Exit )
