View source for SetWaterLevel

__NOTOC__
{{Server client function}}

Sets the height of some or all the water in the game world.
{{Note|When the water level is 0, the standard GTA rendering is performed so that water is visible when viewed through translucent surfaces, such as vehicle windows. However, some MTA custom objects placed underwater will appear in front of the water. Setting the water level to any non-zero value (i.e. setWaterLevel(0.001) ) forces alternative rendering and MTA custom objects placed underwater will be drawn correctly.}}

{{OOP||[[water]]:setLevel|level|getWaterLevel}}

===Required Arguments===
*'''level:''' the new Z coordinate of the water surface. All water in the game world is set to this height.

===Optional Arguments===
*'''theWater:''' the water element to change.

''or:''
{{New feature/item|3.0120|1.2||
*'''includeWaterFeatures :''' a boolean indicating whether to also set the level of water features such as ponds and pools.
*'''includeWaterElements :''' a boolean indicating whether to also set the level of all water elements.
{{Added feature/item|1.5.9|1.5.8|20716|
*'''includeWorldSea :''' a boolean indicating whether to set the level of the sea water
*'''includeOutsideWorldSea:''' a boolean indicating whether to also set the level of sea water outside the world area, ie. outside -3000, 3000.

===Returns===
Returns ''true'' if successful, ''false'' in case of failure.

== Alternate client-only syntax ==
<section name="Client only" class="client" show="true">
<syntaxhighlight lang="lua">bool setWaterLevel ( [float x, float y, float z,] float level )</syntaxhighlight>
===Required Arguments===
*'''level:''' the new Z coordinate of the water surface
===Optional Arguments===
The area of water containing that point or corresponding to that water element is changed.

*'''x:''' the X coordinate of the point indicating the water area to change.
*'''y:''' the Y coordinate of the point indicating the water area to change.
*'''z:''' the Z coordinate of the point indicating the water area to change. This parameter is reserved and is currently ignored, set it to 0.

===Returns===
Returns ''true'' if successful, ''false'' in case of failure (there is no water at the specified coordinates).

This example code adds a command ''water'' which can be used to change the current water level.
<syntaxhighlight lang="lua">

            setWaterLevel ( tonumber( level ) ) -- change the water level
