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).
Syntax
float getWaterLevel ( float posX, float posY, float posZ [ , bool ignoreDistanceToWaterThreshold = false ] )
float getWaterLevel ( water theWater )
Required Arguments
- x: The X axis position
- y: The Y axis position
- z: The Z axis position
or:
- theWater: the water element
Optional Arguments
- ignoreDistanceToWaterThreshold: If set to false, this function returns false, if the difference between water level (without waves) and posZ is greater than 3.0
Returns
Returns an integer of the water level if the localPlayer/position is near the water (-3 to 20 on the Z coordinate) else false if there's no water near the localPlayer/position.
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 = getPlayerFromName ( 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
