This function changes the size of an existing radar area.
bool setRadarAreaSize ( radararea theRadararea, float x, float y )
OOP Syntax Help! I don't understand this!
- Method: radararea:setSize(...)
- theRadararea: the radararea element whose size is to be changed.
- x: the x length of the radar area.
- y: the y length of the radar area.
Returns true if the size was set successfully, false if invalid arguments are passed.
Example 1: This example decreases the size of a team's radar area whenever a player from that team dies:
-- assume that team elements exist and that each player belongs to one of them -- assume that radararea elements exist and that each is a child of one of the teams function playerWasted ( killer, killerweapon, bodypart ) local victimteam = getPlayerTeam ( source ) -- get the team of the victim local killerteam = getPlayerTeam ( killer ) -- get the team of the killer if ( killer and killerteam ~= victimteam ) then -- if there is a killer and he is from an opposing team local victimarea = getElementChild ( victimteam, 0 ) -- get the radararea belonging to the victim's team local x, y = getRadarAreaSize ( victimarea ) -- get the size of the radar area x = x - 5 y = y - 5 setRadarAreaSize ( victimarea, x, y ) -- set a new (smaller) size for the victim's radar area end end addEventHandler ( "onPlayerWasted", root, playerWasted )
Example 2: This example creates a radar area and resets its size right away:
aRadarArea = createRadarArea ( 1024, 1024, 30, 140, 255, 255, 0, 85 ) flag = setRadarAreaSize ( aRadarArea, 50, 90 ) if ( flag ) then outputChatBox ( "Radar area size set successfully!" ) else outputChatBox ( "Failed to set radar area size." ) end
