[QUESTION] isElementAttached

[Chrimam]

Can i use isElementAttached with createBlipAttachedTo? Let's say I want to make make a blip on a player by typing /blip player. if it already has a blip, it will destroy it. will isElementAttached work here? if not, how can i detect if a blip attached to someone?

[bandi94]

for i , elements in pairs(getAttachedElements(player)) do 
  
 if getElementType(elements) == "blip" then 
  
   -- there is a blip attached to the player 
  
end 
 end

addCommandHandler ( "blip", 
  
for i , elements in pairs(getAttachedElements(player)) do 
  
 if getElementType(elements) == "blip" then 
            if ( isElement ( blip ) ) then 
  
                destroyElement ( blip ) 
  
            else 
  
                local x, y, z = getElementPosition ( player ) 
  
                blip = createblip ( TheBlipID) 
  
                attachElements ( blip, player, 0, 0, 2 ) 
  
            end 
  
  
        end 
  
    end 
  
)

This is what I'm trying to do actually. Hope you understand and help

-- partial name function start by TAPL 
function getPlayerFromNamePart(name) 
    if name then  
        for i, player in ipairs(getElementsByType("player")) do 
            if string.find(getPlayerName(player):lower(), tostring(name):lower(), 1, true) then 
                return player  
            end 
        end 
    end 
    return false 
end 
-- partial name function end by TAPL 
  
g_Local = getLocalPlayer() 
  
function followTarget(g_Local, cmd, target) 
    tPlayer = getPlayerFromNamePart(target) 
        if not target then 
         outputChatBox("You have to type a player name.") 
        end 
            if target == g_Local then 
                outputChatBox("You can't follow yourself.") 
            else tMark = createBlipAttachedTo( tPlayer, 0, 2, 255, 255, 255, 255, 0, 99999.0, g_Local) -- if it's not attached already. otherwise, don't attach. 
            end 
end 
  
  
function unfollowTarget(g_Local, cmd, target) 
-- unfollowing thing here by checking if the target is followed already. 
end 
  
addCommandHandler("follow", followTarget) 
addCommandHandler("unfollow", unfollowTarget)

Fixed also some little bugs

-- partial name function start by TAPL 
function getPlayerFromNamePart(name) 
    if name then 
        for i, player in ipairs(getElementsByType("player")) do 
            if string.find(getPlayerName(player):lower(), tostring(name):lower(), 1, true) then 
                return player 
            end 
        end 
    end 
    return false 
end 
  
  
g_Local = getLocalPlayer() 
  
function followTarget(g_Local, cmd, target) 
if not target then 
outputChatBox("You have to type a player name.") 
elseif target then 
tPlayer = getPlayerFromNamePart(target) 
if tPlayer == g_Local then 
outputChatBox("You can't follow yourself.") 
else  
if not isElement ( tMark ) then 
tMark = createBlipAttachedTo( tPlayer, 0, 2, 255, 255, 255, 255, 0, 99999.0, g_Local) 
elseif isElement ( tMark ) then 
destroyElement ( tMark ) 
tMark = createBlipAttachedTo( tPlayer, 0, 2, 255, 255, 255, 255, 0, 99999.0, g_Local) 
end 
end 
end 
end 
  
function unfollowTarget(g_Local, cmd, target) 
if isElement ( tMark ) then 
destroyElement ( tMark ) 
end 
end 
  
addCommandHandler("follow", followTarget) 
addCommandHandler("unfollow", unfollowTarget) 

[Chrimam]

if not isElement ( tMark ) then 
tMark = createBlipAttachedTo( tPlayer, 0, 2, 255, 255, 255, 255, 0, 99999.0, g_Local) 

These lines would be useless if i want to follow more than 1 player. Thanks for the corrections tho

If you want to target more players then you must use tables, much faster than cheking if something is attached on the player

-- partial name function start by TAPL 
function getPlayerFromNamePart(name) 
    if name then 
        for i, player in ipairs(getElementsByType("player")) do 
            if string.find(getPlayerName(player):lower(), tostring(name):lower(), 1, true) then 
                return player 
            end 
        end 
    end 
    return false 
end 
  
  
g_Local = getLocalPlayer() 
  
local followTable = {} 
  
  
function followTarget(g_Local, cmd, target) 
if not target then 
outputChatBox("You have to type a player name.") 
elseif target then 
local tPlayer = getPlayerFromNamePart(target) 
if tPlayer == g_Local then 
outputChatBox("You can't follow yourself.") 
elseif not ( isElement ( followTable[tPlayer] ) ) then  
followTable[tPlayer] = createBlipAttachedTo( tPlayer, 0, 2, 255, 255, 255, 255, 0, 99999.0, g_Local) 
elseif ( isElement ( followTable[tPlayer] ) ) then  
outputChatBox("You are already following this player.") 
end 
end 
end 
  
  
function unfollowTarget(g_Local, cmd, target) 
if not target then 
outputChatBox("You have to type a player name.") 
elseif target then 
local tPlayer = getPlayerFromNamePart(target) 
if isElement (followTable[tPlayer]) then 
destroyElement ( followTable[tPlayer] ) 
end 
end 
end 
  
addCommandHandler("follow", followTarget) 
addCommandHandler("unfollow", unfollowTarget)
