Markers

[Lloyd Logan]

When someone enters a marker, you would use

onMarkerHit(themarkertheyentered)

But if I have many markers, how can I use this so that if they enter any of these markers, one event is triggered (onMarkerHit)

[xXMADEXx]

addEventHandler ( "onMarkerHit", root, function ( p ) 
 -- code 
end )

Create a dummy element with createElement and set this elemenet as parent of your markers with setElementParent. Then define your onMarkerHit event handler attached to the dummy element.

Dummy element has to be a real element, or can be made up?

EDIT: Nevermind, I understand now thanks!

Read the wiki page. What you make with that function won't be a real entity in the world, it will youst behave like an element.

Eg.:

local marker1, marker2 = createMarker ( ... ), createMarker ( ... ) 
local ele = createElement ( "markers" ) 
setElementParent ( marker1, ele ) 
setElementParent ( marker2, ele ) 
  
addEventHandler ( "onMarkerHit", ele, 
    function () 
        outputChatBox ( "hit" ) 
    end ) 

Edit: Great! You are welcome.

I have quite a number of markers, is there any easier way of doing

local marker1, marker2 = createMarker ( ... ), createMarker ( ... ) 
local ele = createElement ( "markers" ) 
setElementParent ( marker1, ele ) 
setElementParent ( marker2, ele )

A loop?

local markers = { 
    createMarker ( ... ), 
    createMarker ( ... ), 
    createMarker ( ... ) 
} 
  
for i, v in ipairs ( markers ) do 
    setElementParent ( v, ele ) 
end

Thank you!

A quick question,

what does;

for i, v in ipairs ( markers ) do 

mean?

It's a loop.
