i need alternative to onClientRender : found one

[[DooD]Heavyair]

i am trying to make my own take on the sam site script but when i use onClientRender to fire the sam site things go a bit wrong.

everything works fine but i cant stop the explosions and it fires way to fast with onClientRender

is there a way of repeatedly firing without using onClientRender or loads of setTimers. oh well here is the script.

server side

area69samsphere = createColSphere ( 354, 2027, -10, 150 ) 
  
function setarea69samsite ( player ) 
   setElementPosition ( area69samsphere, 354, 2027, 25 ) 
   outputChatBox ( "Ready To Fire" ) 
end 
  
function area69samtargeting ( player, matchingDimension ) 
   if ( getElementType ( player ) == "player" ) then 
      triggerClientEvent ( player, "onarea69samfire", getRootElement() ) 
   end 
end 
  
addCommandHandler ( "sam69", setarea69samsite ) 
addEventHandler ( "onColShapeHit", area69samsphere, area69samtargeting ) 

client side

function area69samfiring ( player ) 
   local px,py,pz = getElementPosition ( getLocalPlayer() ) 
   local glow1 = createMarker ( 353, 2030, 30, "corona", 5, 255, 0, 0, 150 ) 
   local shot1 = createObject ( 3106, 353, 2030, 30 ) 
   attachElementToElement ( glow1, shot1, 0, 0, 0 )  
   setTimer ( moveObject, 50, 1, shot1, 500, px, py, pz ) 
   setTimer ( destroyElement, 570, 1, shot1 ) 
   setTimer ( destroyElement, 570, 1, glow1 ) 
   setTimer ( createExplosion, 550, 1, px, py, pz, 0 ) 
end 
  
function area69samfire ( player ) 
   addEventHandler ( "onClientRender", getLocalPlayer(), area69samfiring ) 
   setTimer ( removeEventHandler, 1000, 1, "onClientRender", getLocalPlayer(), area69samfiring ) 
end 
addEvent ( "onarea69samfire", true ) 
addEventHandler ( "onarea69samfire", getLocalPlayer(), area69samfire ) 

i am just messing around with scripting at the moment trying to get an idea of what im doing while i wait for the map editor to come out. any help appreciated. thanx for l kin

Why not use the current tick count method? You can easily create a time-out using the current and previous tick event.

For example:

  
local previousTick = getTickCount() 
local delay = 5000 -- delay loop with 5000ms (5 seconds) 
  
function onClientRender() 
  if (getTickCount() > previousTick + delay) then 
    -- do your thing... 
    previousTick = getTickCount() 
  end 
end

awesome thank u ACE_GAMBIT

i remembered seeing that in one of your previous posts but couldnt remember it exactly to find it on wiki

i think that should be perfect

[Sam Fisher]

Would you please post the script if you finished with it?

[[DooD]Heavyair]

this scripting stuff is getting to be quite fun

the script works but it only fires once ( trying to figure out multiple shots at the moment ) here u go

server side

area69samsphere = createColSphere ( 354, 2027, -10, 150 ) 
  
function setarea69samsite ( player ) 
   setElementPosition ( area69samsphere, 354, 2027, 25 ) 
   outputChatBox ( "Ready To Fire" ) 
end 
  
function area69samtargeting ( player, matchingDimension ) 
   if ( getElementType ( player ) == "player" ) then 
      triggerClientEvent ( player, "onarea69samfire", getRootElement() ) 
   end 
end 
  
addCommandHandler ( "sam69", setarea69samsite ) 
addEventHandler ( "onColShapeHit", area69samsphere, area69samtargeting ) 

client side

local previousTick = getTickCount() 
local area69samfiredelay = 500 
  
function onClientRender ( player ) 
   if ( getTickCount () > previousTick + area69samfiredelay ) then 
      local px,py,pz = getElementPosition ( getLocalPlayer() ) 
      local glow1 = createMarker ( 353, 2030, 30, "corona", 5, 255, 0, 0, 150 ) 
      local shot1 = createObject ( 3106, 353, 2030, 30 ) 
      attachElementToElement ( glow1, shot1, 0, 0, 0 )  
      setTimer ( moveObject, 50, 1, shot1, 500, px, py, pz ) 
      setTimer ( destroyElement, 570, 1, shot1 ) 
      setTimer ( destroyElement, 570, 1, glow1 ) 
      setTimer ( createExplosion, 550, 1, px, py, pz, 0 ) 
      previousTick = getTickCount() 
   end 
end 
  
addEvent ( "onarea69samfire", true ) 
addEventHandler ( "onarea69samfire", getLocalPlayer(), onClientRender ) 

will post changes when i have multiple shots working

thanx again ACE_GAMBIT

EDIT:::

im a bit confused about how to make the function loop so that it fires at u more than once.

i thought that it would detect player hitting collision sphere then fire and then continue checkin the tick count and then fire again after 500ms. i tried using onClientRender to repeatedly do the check on tick count but it just created explosions as soon as i joined the server. i will keep trying though

thanx

[[DooD]Heavyair]

after looking through the LUA tutorials for MTA i saw a function using a WHILE command.

i dont know where to look to find out if i can use this command or how i can use it.

it looks to me like the easiest way to get the samsite to repeatedly fire would be to use the While command for something like

While player is within collision sphere then do the sam site fire function

anybody know where to look or even how to use this command

thanx for any help

[tma]

I'd do something like this for the client (untested / replaces all your client code):

  
function SAMfire() 
    setTimer(SAMfireMissile,500,5)   -- Call to fire a rocket 5 times with 500 ms between each 
end 
  
function SAMfireMissile ( player ) 
      local px,py,pz = getElementPosition ( getLocalPlayer() ) 
      local glow1 = createMarker ( 353, 2030, 30, "corona", 5, 255, 0, 0, 150 ) 
      local shot1 = createObject ( 3106, 353, 2030, 30 ) 
      attachElementToElement ( glow1, shot1, 0, 0, 0 ) 
      setTimer ( moveObject, 50, 1, shot1, 500, px, py, pz ) 
      setTimer ( destroyElement, 570, 1, shot1 ) 
      setTimer ( destroyElement, 570, 1, glow1 ) 
      setTimer ( createExplosion, 550, 1, px, py, pz, 0 ) 
end 
  
addEvent ( "onarea69samfire", true ) 
addEventHandler ( "onarea69samfire", getLocalPlayer(), SAMfire)

thanx for your reply TMA

i have got this working ( hurray )

it detects player inside collision sphere and repeatedly fires until u leave collision sphere.

it gives two errors in debugscript 3

one is event allready handled which i think is because the removeEventHandler isnt right

second is attempt to call nil value when it stops firing but i think that is the removeEventHandler again

but it works and it looks pretty cool. i will try and do some screenshots but it shoots pretty fast.

the only way i could get isElementWithinColShape to work was by making collision spheres for client and server but it doesnt seem to be a problem. i am going to try and get the rest of the sam sites firing now ( maybe add some hidden / pop up ones )

server side

   outputChatBox ( "Ready To Fire" )

function area69samtargeting ( player, matchingDimension ) 
   if ( getElementType ( player ) == "player" ) then 
       triggerClientEvent ( player, "onarea69samfire", getRootElement() )

   detection = isElementWithinColShape ( getLocalPlayer(), area69samsphere ) 
      if detection == true then
