Funny: /* Example */

{{Server client function}}
__NOTOC__
This function sets the alpha(transparency) value for the specified [[element]]. This can be a [[player]] or a [[vehicle]].

==Syntax==
<syntaxhighlight lang="lua">
bool setElementAlpha ( element theElement, int alpha )
</syntaxhighlight>

===Required Arguments===
*'''theElement:''' The [[element]] whose alpha you want to set.
*'''alpha:''' The alpha value to set. Value can be 0-255, where 255 is fully opaque and 0 is fully transparent.
===Returns===
Returns ''false'' if invalid arguments were passed.

==Example==
<section name="Clientside example" class="client" show="true">
This example makes the player invisible.
<syntaxhighlight lang="lua">
function invisible()
setElementAlpha(getLocalPlayer(), 0)
end
addCommandHandler ( "invisible", invisible )
</syntaxhighlight>
</section>

<section name="Serverside example" class="server" show="true">
This example lets you toggle invisibility when you write /invis.
<syntaxhighlight lang="lua">
function toggleInvis ( source ) -- source is whoever executed the command
function qb = getElementAlpha(source) -- get the actual alpha for check if i'm visible
if qb == 0 then -- if the source player is NOT invisible
setElementAlpha ( source, 0 ) -- set the players alpha to 0 (make them invisible)
else -- else, if the source player IS visible
setElementAlpha ( source, 255 ) -- set the players alpha to 255 (make them 100% visible)
end
end
addCommandHandler ( "invis", toggleInvis ) -- When /invis is typed, the function 'toggleInvis' will start.

SetElementCollidableWith

2012-02-28T17:50:33Z

Funny: /* Example */

{{Client function}}
{{Needs Example}}
__NOTOC__
This function can be used to set an element to collide with another element. An element with collisions disabled does not interact physically with the other element.<br>
'''Note:''' You can only use this function with the element types listed below.
*[[Player]]
*[[Ped]]
*[[Vehicle]]
*[[Object]]

==Syntax==
<syntaxhighlight lang="lua">
bool setElementCollidableWith ( element theElement, element withElement, bool enabled )
</syntaxhighlight>

===Required Arguments===
*'''theElement:''' The [[element]] which colliding you want to change
*'''withElement:''' The other [[element]] you wish the first entity to collide with
*'''enabled:''' A boolean to indicate whether elements should be able to collide with eachother (''true'') or not (''false'')

===Returns===
Returns ''true'' if the collisions were set succesfully, ''false'' otherwise.

==Example==
<section name="Client" class="client" show="true">
<syntaxhighlight lang="lua">

function ghostmode_on()
local localPlayer = getLocalPlayer() -- Getting the Local Player
local v = getPedOccupiedVehicle(localPlayer) -- Get her's Vehicle ID
for index,vehicle in ipairs(getElementsByType("vehicle")) do --LOOP through all Vehicles
setElementCollidableWith(vehicle, v, false) -- Set the Collison off with the Other vehicles.
end
outputChatBox("You are now a Ghost :P",thePlayer)
end
addCommandHandler("ghostmode", ghostmode_on) -- Add the /ghostmode Command.
