Object Check

[lolek123]

How can I make server check my objects and make marker on object model ID 2916, any help? Please.

What do you mean? Checking an object that hits marker or what?

[lolek123]

No. I want my server to do an auto check after the server starts.. And whenever it finds an object with Model ID 2916 it will create a marker on it.

This will work after your resource starts.

Server-side:

  
function CheckMyObject(res) 
if res==getThisResource() then 
for _,object in ipairs(getElementsByType("object")) do 
if getElementModel(object)==2916 then 
local x,y,z=getElementPosition(object) 
local int=getElementInterior(object) 
local dim=getElementDimension(object) 
myMarker=createMarker(x,y,z,"cylinder",2.0,255,0,0,125) 
setElementInterior(myMarker,int) 
setElementDimension(myMarker,dim) 
end 
end 
end 
end 
addEventHandler("onResourceStart",getRootElement(),CheckMyObject)

Hi, how you know how many "end" will add ?

[AMARANT]

Because every "if", loop or function must be closed with "end" operator. Install Notepad++ it can help you to figure this out.

Yeah, i have notepad. what is loop ? and there is 1 function, 2 if's and 4 end's ???

[AMARANT]

The 4th "end" is loop actually.

but what is loop ?

can you pls give me 2 or 3 examples if that is not single function ?

[lolek123]

"for _,object in ipairs(getElementsByType("object")) do"

could you kinda explain and simplify this part for me? I dont really understand the in ipairs.

I'm not good at explaining the lua basics. For that you can find more with google or tutorials on MTA wiki. And I made an example above for lolek123. But here is one more:

  
function outputForPerfect(player) 
for i,player in ipairs(getElementsByType("player") do -- Here's looping through all player elements in order to find what we want. Loops are usually used to check tables or to shorten a code so you can write several lines of your script instead of writing hundred. 
if getPlayerName(player)=="Perfect" then -- We wanted to find a player with nickname "Perfect". Here we are 
outputChatBox("Bla-bla-bla...",player,0,255,0) -- And finally we output a message to him. 
end 
end 
end 
addCommandHandler ( "loop", outputForPerfect )
