{{Client function}}
{{New feature/item|3.0161|1.6.0|22219|Does a raycast against an element's renderable mesh model directly}}
Does a raycast against an element's renderable mesh model [not the collision model!].
The same functionality is already present in [[processLineOfSight]], but the latter is a little buggy due to the fact that the collision model is always simplified, and not exactly the same as the mesh, which leads to situations where no hit is detected, even though the visible mesh is hittable [or vice versa].
Also, when one is interested in a specific element the overhead is a lot smaller [as we can skip all the collision detection done by the before-mentioned function].

==Syntax==

Single line for convenience.
<syntaxhighlight lang="lua">
bool, float, float, string, string, float, float, float processLineAgainstMesh(element toTest, float startX, float startY, float startZ, float endX, float endY, float endZ)
</syntaxhighlight>

Return values labelled for ease of reference.
<syntaxhighlight lang="lua">
bool -- hit
float float -- texU, texV
string -- textureName
string -- frameName
float float float -- worldX, worldY, worldZ
processLineAgainstMesh(element toTest,
float startX, float startY, float startZ,
float endX, float endY, float endZ)
</syntaxhighlight>

===Required Arguments===
*'''toProcess:''' The element to process the line against
*'''startX, startY, startZ:''' The start [origin] of the line
*'''endX, endY, endZ:''' The end of the line

===Returns===
*'''hit:''' ''true'' if there is a collision with the given element's mesh, ''false'' otherwise [in which case all other values are nil]
*'''texU, texV:''' the U, V coordinates on the hit geometry's texture
*'''textureName:''' name of the hit geometry's texture
*'''frameName:''' hit frame's name
*'''worldX, worldY, worldZ:''' collision position in world space

==Example==
This example prints the name of the texture hit by the player's crosshair on any vehicle in the world. It uses processLineAgainstMesh to check for collisions between a line from the camera to a point in front of it and the meshes of vehicles.

ProcessLineAgainstMesh

2026-04-05T17:02:33Z

Blond6: This example demonstrates how to use processLineOfSight to determine what the player is looking at. It gets the camera position and a point in front of it, then checks for a line of sight between those points. If something is hit, it outputs the coordinates and the type of element hit.

Blond6: Remove spaces

{{Server function}}
{{Needs_Example}}
__NOTOC__
This function retrieves the priority of a text item. Priority defines the rate at whihc a text item is updated

==Syntax==
<syntaxhighlight lang="lua">
int textItemGetPriority ( textitem textitemToCheck )
</syntaxhighlight>

===Required Arguments===
*'''textitemToCheck:''' The text item you wish to retrieve the priority of.

===Returns===
Returns a integer of the priority of a text item, 0 = low, 1 = medium, 2 = high.

TextItemSetPriority

2023-10-29T21:15:52Z

Blond6: Remove spaces

__NOTOC__
{{Server function}}
{{Needs_Example}}
This function sets the priority for a text item. Priority is the importance of sending updated text to the client. The system is implemented as 3 queues, with the ''high'' queue being emptied before the ''medium'' queue is processed, and with one update sent per server frame. Hence, if you set all your text items to ''medium'' priority it has the same effect as if you set them all to ''high'' or ''low''.

==Syntax==
<syntaxhighlight lang="lua">
void textItemSetPriority ( textitem theTextItem, string priority )
</syntaxhighlight>

===Required Arguments===
*'''theTextItem:''' The text item you wish to set priority to.
*'''priority:''' The priority you wish to set to the item, which can be ''"high"'', ''"medium"'', or ''"low"'' respective of their priority.

===Returns===
Returns four integers in RGBA format, with a maximum value of 255 for each. The values are, in order, ''red'', ''green'', ''blue'', and ''alpha''. Alpha decides transparency where 255 is opaque and 0 is transparent. ''false'' is returned if the text item is invalid.

==Example==
This example gets the color of a text item named 'theTextItem' and if it is green, changes it to blue.
<syntaxhighlight lang="lua">

__NOTOC__ {{Important Note|If you wish to retrieve more than one element at a time, it is more efficient to use [[getElementsByType]] instead.}}
{{Server client function}}
This function returns an element of the specified type with the specified index.

==Syntax==
<syntaxhighlight lang="lua">
element getElementByIndex ( string theType, int index )
</syntaxhighlight>
{{OOP|This function is a static function inside the Element class.|[[Element]].getByIndex||}}

===Required Arguments===
*'''theType:''' the type of the element to be returned. Examples include "player", "vehicle", or a custom type.
*'''index:''' the element's index (0 for the first element, 1 for the second, etc).

===Returns===
Returns the requested [[element]], or ''false'' if it doesn't exist.

==Example==
This example outputs the name of the specified vehicle currently existent in the XML tree. For example: 'vehicle 0' would return the first vehicle.
<syntaxhighlight lang="lua">
function showVehicle(thePlayer, command, index)
local theVehicle = getElementByIndex("vehicle", tonumber(index))
if theVehicle then
outputChatBox("Vehicle " .. index .. " is a: " .. getVehicleName(theVehicle), thePlayer)
else
outputChatBox("Vehicle not found.", thePlayer)
end
end
addCommandHandler("vehicle", showVehicle)
</syntaxhighlight>

Blond6: Remove spaces

__NOTOC__
{{Server client function}}
{{New feature/item|3.0156|1.5.5|14165|Sets the angular velocity of a specified, supported element (Applies a spin to it).}}

==Syntax==
<syntaxhighlight lang="lua">
bool setElementAngularVelocity ( element theElement, float rx, float ry, float rz )
</syntaxhighlight>
{{OOP||[[element]]:setAngularVelocity|angularVelocity|getElementAngularVelocity}}
===Required Arguments===
*'''theElement:''' The [[element]] to apply the spin to. Can be either a [[player]], [[ped]], [[object]], [[vehicle]] or a [[Element/Weapon|custom weapon]].
*'''rx:''' velocity around the X axis
*'''ry:''' velocity around the Y axis
*'''rz:''' velocity around the Z axis

===Returns===
Returns ''true'' if it was succesful, ''false'' otherwise.

==Example==
<syntaxhighlight lang="lua">
function onColShapeHit ( thePlayer, matchingDimension )
-- When a player hits the collision shape, give him a spin
setElementAngularVelocity ( thePlayer, 0, 0, 20 )
end
addEventHandler ( "onColShapeHit", root, onColShapeHit )
</syntaxhighlight>

Blond6: Remove spaces

{{Server client function}}
__NOTOC__
Some elements have an associated colshape, for example [[Marker]] and [[Pickup]]. This function is used to get the associated colshape.

==Syntax==
<syntaxhighlight lang="lua">
colshape getElementColShape ( element theElement )
</syntaxhighlight>
{{OOP||[[element]]:getColShape|colShape|}}

===Required Arguments===
*'''theElement:''' The element you want to get the colshape of

===Returns===
Returns ''colshape'' of the element, ''false'' if not or an invalid argument was passed to the function.

==Example==
<section class="server" name="Server" show="true">
This example creates a marker inside Toreno's house and adds a command to check whether you are standing on it.
<syntaxhighlight lang="lua">
theMarker = createMarker( -687.9, 937.8, 13.6, "cylinder", 2.0, 255, 0, 0, 80 ) -- create a red cylinder marker inside Toreno's house

function checkOnMarker ( thePlayer )
local isIn = isPlayerInMarker( thePlayer, theMarker ) -- use the function to check if player is in the marker
if isIn then
outputChatBox( "You are on the marker.", thePlayer )
else
outputChatBox( "You are not on the marker.", thePlayer )
end
end
addCommandHandler ( "amionmarker", checkOnMarker )

-- define the isPlayerInMarker function
function isPlayerInMarker( thePlayer, theMarker )
local theShape = getElementColShape( theMarker ) -- get markers colshape
if isElementWithinColShape( thePlayer, theShape ) then -- check if the player is in it
return true
else -- he isn't on the marker
return false
end
