This function allows you to retrieve the water level from a certain location. The water level is 0 in most places though it can vary (e.g. it's higher near the dam).

Note: Some areas inside land do not count as water. For example, the shallow water in Northwest San Fierro.

Syntax

bool/float getWaterLevel ( float posX, float posY, float posZ )

Required Arguments

  • x: The X axis position
  • y: The Y axis position
  • z: The Z axis position

Returns

Returns false if there's no water in that location or the water level as an integer if you're near the water (-3 to 20 on the Z coordinate).

Example

This example will tell you what's the water level where the specified player is located. 

function scriptGetLevel ( command, playername ) --when getlevel is called
  local thePlayer = getPlayerFromNick ( playername ) --get the player from nickname
  if ( thePlayer ~= false ) then --if there is a player from the nickname
    local x, y, z = getElementPosition ( thePlayer ) -- get his position
    local level = getWaterLevel ( x, y, z )
	  if level then -- if it's not false
        level = z - level -- calculate how far away is he from the water
        outputChatBox( "You are " .. level .. " units away from the water!", source )
	  else outputChatBox ( "There's no sign of water" )
	  end
  else outputChatBox ( "Player does not exist" )
  end
end
addCommandHandler( "getlevel", scriptGetLevel ) -- add a command "getloc" which
