SetElementVisibleTo

2011-06-27T19:08:39Z

Maggi: /* Example */

__NOTOC__
{{Server function}}
{{Needs_Checking|Can an element only be visible to one element (and its children) at a time? If so, do we need clearElementVisibleTo? If not, surely we need to remove the root element before using this function?|[[User:EAi|EAi]]
}}

This function can change an [[element]]'s [[visibility]]. This does not work with all entities - [[vehicle]]s, [[player]]s and [[object]]s are exempt. This is because these objects are required for accurate sync (they're physical objects). This function is particularily useful for changing the visibility of markers, radar blips and radar areas.

==Syntax==
<syntaxhighlight lang="lua">
bool setElementVisibleTo ( element theElement, element visibleTo, bool visible )
</syntaxhighlight>

===Required Arguments===
*'''theElement:''' The element you want to control the visibility of.
*'''visibleTo:''' The element you wish the element to be visible or invisible to. Any child elements that are players will also be able to see the element. See [[visibility]].
*'''visible:''' Whether you are making it visible or invisible to the player.

===Returns===
Returns ''true'' if the element's visibility was changed successfully, ''false'' otherwise, for example if you are trying to change the visibility of a vehicle, player or object.

==Example==
This example creates a marker and makes it only visibile to the player called 'someguy'.
<syntaxhighlight lang="lua">
-- Find the player called someguy
local someguy = getPlayerFromName ( "someguy" )
-- If the player was found then
if ( someguy ) then
-- Get the player's position into the variables x, y and z
x, y, z = getElementPosition ( someguy )
-- Create a marker at the player's position
myMarker = createMarker ( x, y, z )
-- First off make the marker invisible to the whole dimension
setElementVisibleTo ( myMarker, getRootElement ( ), false )
-- Then make the marker visible again, but only to someguy
setElementVisibleTo ( myMarker, someguy, true )
end
</syntaxhighlight>

The following example shows how to hide the marker on 'someguy' from 'anotherguy'
<syntaxhighlight lang="lua">
-- Find the player called someguy
local someguy = getPlayerFromName ( "someguy" )
local anotherguy = getPlayerFromName ( "anotherguy" )
-- If the player was found then
if ( someguy ) then
-- Get the player's position into the variables x, y and z
x, y, z = getElementPosition ( someguy )
-- Create a marker at the player's position
myMarker = createMarker ( x, y, z )
-- First off make the marker visible especially to 'anotherguy'
setElementVisibleTo ( myMarker, anotherguy, true )
-- Then hide it
setElementVisibleTo ( myMarker, anotherguy, false )
end
</syntaxhighlight>
