    [HELP] Element Rotation

    in Scripting

    Posted

    Thanks IIYAMA, FindRotation3D worked for the getting rotation. 🙏


    Did not achieve the desired result with a rocket projectile (19) though. Even after rotating it directly at point_B the projectile eventually starts heading out in a different direction, not exactly sure whats up with that. I think an easy way to fix that is using createObject along with moveObject and stuff, but in this case, what should I use to properly send projectiles from point A to point B since createProjectile only has starting position arguments to work with?

    Are you using this function?

    Attach a dummy vehicle to the object and set the vehicle as the creator of the projectile.

    Because else your camera is used for the direction.

    But how do I render the HUD without onClientRender()?

    As Justn and me mentioned:

    Just a thing that can lead up to a crash:

    • By putting dxCreateFont/dxCreateTexture/dxCreateScreenSource(everything with Create in it's name) inside of an onClientRender triggered function

     

    Move this line to the top of your code:

     local Inventory = dxCreateTexture("Inventory.png")

     

    Like this: 

    local sx,sy = guiGetScreenSize()
local px,py = 1600,900
local x,y =  (sx/px), (sy/py)		

local Inventory = dxCreateTexture("Inventory.png") -- just put it here and not inside of HUDDrawing.

function HUDDrawing()

  --[[ ... ]]

    I think that's why it is crashing.

    Is there a better way to use dxDrawRect and dxDrawText then onClientRender?

    The following functions shouldn't cause crashes:

    https://wiki.multitheftauto.com/wiki/DxDrawRectangle

    https://wiki.multitheftauto.com/wiki/DxDrawText

     

    But you most likely did crash because of a memory leak. To find the reason I will need to look at your code for that.

    Just a thing that can lead up to a crash:

    • By putting dxCreateFont/dxCreateTexture/dxCreateScreenSource(everything with Create in it's name) inside of an onClientRender triggered function

     

     

    fileExists / dxDrawImage

    So perhaps fileExists being used onClientRender

    I wouldn't run that function either in combination with onClientRender.

    Since you are fetching the file from another resource, you could increase or decrease the download priority for either resource.

    https://wiki.multitheftauto.com/wiki/Meta.xml

    Or just wait a little bit longer before start rendering.
    (I also recommend to convert the image into a texture before rendering)

    The Console has full access, so it might be possible that you currently have no access to begin with.

     

    Steps to add the initial admin account (later on you can add more admins ingame using the User Interface):

    1. Stop the server
       
    2. Open the ACL file: MTA San Andreas 1.6\server\mods\deathmatch\acl.xml
       
    3. Make a back up of this ACL file
       
    4. Scroll to (in the original one): 
          <group name="Admin">
        <acl name="Moderator"></acl>
        <acl name="SuperModerator"></acl>
        <acl name="Admin"></acl>
        <acl name="RPC"></acl>
        <object name="resource.admin"></object>
        <object name="resource.webadmin"></object>
        <object name="resource.acpanel"></object>
    </group>

       

    5. Add an account looking like this: 
              <object name="user.example"></object>
      Replace example with your username even if the account does not exist yet. (keep it simple)

      And add it like this: 
          <group name="Admin">
        <acl name="Moderator"></acl>
        <acl name="SuperModerator"></acl>
        <acl name="Admin"></acl>
        <acl name="RPC"></acl>
        <object name="resource.admin"></object>
        <object name="resource.webadmin"></object>
        <object name="resource.acpanel"></object>
        <object name="user.example"></object>
    </group>
    6. Save the file
       
    7. Start the server again (if you broke the syntax of the file, the server will not start, that is why step 3 so you can start over)
       
    8. Go ingame
      1. Add the account if not exist: /register <example username> <new password>
      2. /login <example username> <current password>

    There is a difference in the panel and command access.

    This is for example a part of the rights for Moderators. 

    <acl name="Moderator">
        <right name="general.ModifyOtherObjects" access="false"></right>
        <right name="command.gamemode" access="true"></right>
        <right name="command.changemode" access="true"></right>
        <right name="command.changemap" access="true"></right>
        <right name="command.stopmode" access="true"></right>
        <right name="command.stopmap" access="true"></right>
        <right name="command.skipmap" access="true"></right>
        <right name="command.mute" access="true"></right>
        <right name="command.unmute" access="true"></right>
        <right name="command.whois" access="true"></right>
        <right name="command.whowas" access="true"></right>
        <right name="function.setPlayerMuted" access="true"></right>
        <right name="function.kickPlayer" access="true"></right>
        <right name="function.banPlayer" access="true"></right>
        <right name="function.getBans" access="true"></right>
        <right name="function.addBan" access="true"></right>
        <right name="function.startResource" access="true"></right>
        <right name="function.stopResource" access="true"></right>
        <right name="function.restartResource" access="true"></right>
        <right name="function.refreshResources" access="true"></right>
        <right name="function.redirectPlayer" access="true"></right>
        <right name="general.adminpanel" access="true"></right>
        <right name="general.tab_players" access="true"></right>
        <right name="general.tab_resources" access="false"></right>
        <right name="general.tab_maps" access="false"></right>
        <right name="general.tab_server" access="true"></right>
        <right name="general.tab_bans" access="false"></right>
        <right name="general.tab_adminchat" access="true"></right>

      

    <right name="command.mute" access="true"></right>
<right name="general.tab_bans" access="false"></right>

    You can see that the moderator can mute a player using /mute, but does not have access to the ban tab.

     

    How did you grand yourself access rights?

    if tonumber(ID) then

    You should move this condition before the loop

    and if it fails,

    do the outputChatBox + return statement.

    Could you explain what this code does?

    It inserts a row into the database and returns the generated primary key.

    But most of it are just examples for you to apply in to your own code. (also not tested, I haven't combined insert + update with the multipleResults statement myself)

     

    If something is unclear, please be specific in which part or function you do not understand. Then I will explain how that part/function works.

    MYSQL

     

    In that case you can try to work with the following building blocks. (untested)

      

    local userName = "root"
local password = "root"
local host = "127.0.0.1"
local db = dbConnect( "mysql", host, userName, password,
    "multi_statements=1"  -- optional
)

-- ...

local player -- = ???
local serial = 1234567890
if db then
    
    dbQuery(onRegisterPlayer, {player}, db, [[
        INSERT INTO characters (serial) VALUES (?) 
        ON DUPLICATE KEY UPDATE id=VALUES(id);
    ]], serial)
end

-- ...

---@param queryHandle userdata
---@param player userdata
function onRegisterPlayer(queryHandle, player)
    if not isElement(player) then return end
    local multipleResults = true -- return the id of the inserted row
    local result = dbPoll(queryHandle, -1, multipleResults)
    if not result then
        --- Something went wrong
        error("Failed to register player")
        return
    end
    iprint("Table", result[1])
    iprint("Affected rows", result[2])
    iprint("Last insert id", result[3])
end

    At each entry, you set a SetElementData for the value of the ID table

    And at what point do you save the character?

    After filling in info of some sort?

    So I have the problem that every player gets an ID with setElementData when, for example, ID 1 appears based on the primary row of the SQL table But when the command is entered on the server, the system only works with a player with a specific ID, e.g. we can TP the player with a specific ID, etc.

     

     

    So you mean the user case when no ID is assigned to a new player?

    Based on what criteria are you assigning the ID?

    Yes, but does it need a name argument? However, I would like to solve it with ID

    It does indeed

     

    In that case, could you explain the following with some more context?

    3 hours ago, Firespider said:

    problem is that the players have an ID, but the system only detects the individual ID

    It is unclear what an `individual ID` is in the current context.

    No, it returns a player<element> or nil 

    function getPlayerFromPartialName(name)
    local name = name and name:gsub("#%x%x%x%x%x%x", ""):lower() or nil
    if name then

local name = "IIYAMA"
local player = getPlayerFromPartialName ( name )
if player then

else
	-- Not found
