markers issue...

[aintaro]

Hello guys,

Lets say you have 100 markers on the map, how would you go and write a code that checks if a CERTAIN marker has been hit by the player?

thanks in advance,

You can use one of these events:

onMarkerHit --> server side

onClientMarkerHit --> client side

[aintaro]

those would only tell if we hit a marker, but not a CERTAIN marker

[Castillo]

You can attach the event handler to the marker you want to trigger the function.

use a loop, firstly make a table in all the positions:

  
pos = { 
--{x,y,z} 
} 
  
  
for i,v in ipairs(pos) do 
local x,y,z = unpack(pos[i]) 
createMarker(x,y,z ......) 
end 
  
closestMarker  = 9999999999999999  
  
addEventHandler("onMarkerHit",root,  
function (player) 
for i,v in ipairs(pos) do 
local x,y,z = unpack(pos) 
x1 , y1,z1 = getElementPosition(player) 
distance2 = getDistanceBetweenPoints3D(x,y,z,x1,y1,z1) 
--tell me what do you want then? 
end 
end 
)

thanks arnold, thats what I wanted

You're Welcome.

addEventHandler("onMarkerHit",root,  
function (player) 
    -- source is the marker that you hit when root is the attached element, to get the distance, use this 
    local max,may,maz = getElementPosition(source) 
    local px,py,pz = getElementPosition(player) 
    local distance = getDistanceBetweenPoints3D( max,may,maz, px,py,pz ) 
end) 

Don't use loops where it's not needed, this will give you both the marker element and the distance from this marker element to the player or element that just hit it, I'm not sure what you are trying to do but this should cover anything you need in a way more efficient way.
