This function creates a marker. A marker is a 3D model in the world that can highlight a particular point or area, often used to instruct players where to go to perform actions such as entering buildings.
Syntax
marker createMarker ( float x, float y, float z, [string type, int size, int r, int g, int b, int a] )
Required Arguments
- x: A floating point number representing the X coordinate on the map.
- y: A floating point number representing the Y coordinate on the map.
- z: A floating point number representing the Z coordinate on the map.
Optional arguments
- type: The visual type of the marker to be created. Possible values:
- "checkpoint": Checkpoint (Note: Currently z position is always ground-level. Only remains visible to a certain height.)
- "ring": Ring (doughnut-shaped)
- "cylinder": Cylinder (Note: Currently z position is always ground-level.)
- "arrow": Animated arrow pointing down
- "corona": A glowing area
- size: The diameter of the marker to be created, in meters.
- r: An integer number representing the amount of red to use in the colouring of the marker (0 - 255).
- g: An integer number representing the amount of green to use in the colouring of the marker (0 - 255).
- b: An integer number representing the amount of blue to use in the colouring of the marker (0 - 255).
- a: An integer number representing the amount of alpha to use in the colouring of the marker (0 - 255).
Returns
Returns the marker element that was created, or false if the arguments are incorrect.
Example
Example 1: This example creates a marker at the player's position when they type !createmarker in the chat box.
addCommandHandler ( "createmarker", "consoleCreateMarker" )
-- this functions is called whenever someone types 'createmarker':
function consoleCreateMarker ( thePlayer, commandName )
if ( thePlayer ) then
local x, y, z = getElementPosition ( thePlayer ) -- get the player's position
-- create a cylindrical marker next to the player:
local theMarker = createMarker ( x + 2, y + 2, z, "cylinder", 1.5, 255, 255, 0, 170 )
if ( theMarker ) then -- check if the marker was created successfully
outputConsole ( "Marker created successfully", thePlayer )
else
outputConsole ( "Failed to create marker", thePlayer )
end
end
end
Example 2: Create a marker at the coordinates 0, 0, 20:
createMarker ( 0, 0, 20 )

NEEDS CHECKING
- Arrow has an extreme bounce... it needs to be definable.
- Detection radius is huge for all... can this be optional or adjusted to be smaller?
- Corona (glow balls) dont show under black color 0, 0, 0
- Coronas don't always disappear client-side when they are destroyed.
