ok I want to make the TaxiJob with out creating a Team that will show on tab.. how would i start this off on client and server?

[xXMADEXx]

You can use element data to store the player job, to check it if you need it. You'll need: setElementData, getElementData

[diesel974]

i had made a taxi job but mostly server side, so as to protect my codes from being copied or stolen. Also, its a good practice to make ur scripts mostly server side so that the clients( i mean the other players) dont have too much to download.

Heres a simple plan of how i made the script :

i made the marker, so that when the player enters it, a gui will appear to him so that he can choose to take the job or not. (server side)

i made the guis

when the player press the accept job button, gui disappear and trigger server to give the job to the player.

create a table for the locations of the markers and the peds

start the job

give the taxi to the player

create marker1 and ped

when player hits marker1, warp the ped into the taxi

destroy marker1, and create marker2

when player hits marker2, remove the ped from the taxi and give the player his money

now, this can be elaborated more, and if you are doing the job serverside, you gonna use setElementData and getElementData to avoid collisions....

read more about that a wiki

[#Ivan7]

I know i did same thing... but now i want imrpove my script make it more complex for example now im practicing dxDrawText and im having problems with that to

[#Ivan7]

this would be the client side :

local g_screenX, g_screenY = guiGetScreenSize();

local gScale = 0.3;

local gAlphaDistance = 25;

local gMaxDistance = 50; -- Max Distance

local gTextAlpha = 120;

local gTextSize = 1;

local gAlphaDiff = gMaxDistance - gAlphaDistance;

gScale = 1 / gScale * 800 / g_screenY;

local gMaxScaleCurve = { { 0, 0 }, { 3, 3 }, { 13, 5 } };

local gTextScaleCurve = { { 0, 0.8 }, { 0.8, 1.2 }, { 99, 99 } };

local gTextAlphaCurve = { { 0, 0 }, { 25, 100 }, { 120, 190 }, { 255, 190 } };

local markertaxi = createMarker( -2479.9282226563, -197.41656494141, 24.623662948608, 'Cylinder', 1.5, 255, 0, 255, 170 );

-- Marker #1

if distance_1 <= gMaxDistance then

local x1_, y1_ = getScreenFromWorldPosition( x1, y1, z1 + 0.95, 0.06 );

if x1_ and y1_ then

--

local scale = 1 / ( gScale * ( distance_1 / gMaxDistance ) );

local alpha = ( ( distance_1 - gAlphaDistance ) / gAlphaDiff );

alpha = ( alpha < 0 ) and gTextAlpha or gTextAlpha - ( alpha * gTextAlpha );

scale = math.evalCurve( gMaxScaleCurve, scale );

end local textscale = math.evalCurve( gTextScaleCurve, scale );

local textalpha = math.evalCurve( gTextAlphaCurve, alpha );

end --

dxDrawText( "Taxi Job", x1_, y1_, x1_, y1_, tocolor ( 255, 255, 255, textalpha ), textscale * gTextSize, "arial", "center", "bottom", false, false, false, true );

end

return curve[ #curve ][ 2 ];

return from + ( to-from ) * alpha;

[diesel974]

Sorry, but i never used dxDrawText ;/ i always tried to keep my scripts as simple as i can

[#Ivan7]

Problem for this is it doesnt show the dxDrawText and im deleting all the joinTeam so should i just replace all joinTeam with a setElementData and getElementData

[#Ivan7]

Its alright diesel thanks for the reply though

[xXMADEXx]

dxDrawText is a really basic function, once you start to understand it. You just have to make sure you put it into one of the render events. Here is a basic example:

addEventHandler ( "onClientRender", root, function ( ) 
  
    dxDrawText ( "This is my direct x text!", 0, 0, 500, 20 ) 
  
end ) 

[#Ivan7]

I have that but it just wont show up

addEventHandler ( 'onClientRender', root,

function ( )

--

local x, y, z = getCameraMatrix();

local x1, y1, z1 = getElementPosition ( markertaxi );

local distance_1 = getDistanceBetweenPoints3D( x, y, z, x1, y1, z1 );

--

-- Marker #1

if distance_1 <= gMaxDistance then

local x1_, y1_ = getScreenFromWorldPosition( x1, y1, z1 + 0.95, 0.06 );

if x1_ and y1_ then

--

local scale = 1 / ( gScale * ( distance_1 / gMaxDistance ) );

local alpha = ( ( distance_1 - gAlphaDistance ) / gAlphaDiff );

alpha = ( alpha < 0 ) and gTextAlpha or gTextAlpha - ( alpha * gTextAlpha );

scale = math.evalCurve( gMaxScaleCurve, scale );

end local textscale = math.evalCurve( gTextScaleCurve, scale );

local textalpha = math.evalCurve( gTextAlphaCurve, alpha );

end --

dxDrawText( "Taxi Job", x1_, y1_, x1_, y1_, tocolor ( 255, 255, 255, textalpha ), textscale * gTextSize, "arial", "center", "bottom", false, false, false, true );

end

);

Tell me if debugscript says anything (if it does, take a screenshot and upload the error to http://imgur.com)

(Debug: /debugscript 3)

[#Ivan7]

Nah it does say anything..

[#Ivan7]

Actually it said this: http://imgur.com/okPkkjZ

Plz use the Lua tag to make code reading easier .

Also, indent your codes.. oka, lets get to the real deal :

addEventHandler ( 'onClientRender', root, 
function ( ) 
-- 
local x, y, z = getCameraMatrix(); 
local x1, y1, z1 = getElementPosition ( markertaxi ); 
local distance_1 = getDistanceBetweenPoints3D( x, y, z, x1, y1, z1 ); 
  
-- 
-- Marker #1 
   if distance_1 <= gMaxDistance then 
             local x1_, y1_ = getScreenFromWorldPosition( x1, y1, z1 + 0.95, 0.06 ); 
              if x1_ and y1_ then 
                      -- 
                      local scale = 1 / ( gScale * ( distance_1 / gMaxDistance ) ); 
                       local alpha = ( ( distance_1 - gAlphaDistance ) / gAlphaDiff ); 
                       alpha = ( alpha < 0 ) and gTextAlpha or gTextAlpha - ( alpha * gTextAlpha ); 
                       scale = math.evalCurve( gMaxScaleCurve, scale ); 
               end  
         local textscale = math.evalCurve( gTextScaleCurve, scale ); 
         local textalpha = math.evalCurve( gTextAlphaCurve, alpha ); 
   end -- 
dxDrawText( "Taxi Job", x1_, y1_, x1_, y1_, tocolor ( 255, 255, 255, textalpha ), textscale * gTextSize, "arial", "center", "bottom", false, false, false, true ); 
end 
) 

oka,like debugscript said, : attempt to perform arithmetic on global "textscale" (a nil value), means that textscale is nil here, it does not hold any value. So, look at your codes. your problem is on the line 19, you defined textscale...oka, but then, when you are about to use it on the line 22, textscale is already out of scope, mean, in the block you had defined it (from line 10 to 21), at the end of line 21, the local variable textscale becomes nil bekoz it is local and its out of scope since its block has already ended. So, the solution would be to transfer the line 22 below the line 20

[#Ivan7]

No it doesnt work its fine thought i took it out ..

[#DRAGON!FIRE]

Just remove marker on line 2 and set ur marker name and set Text

addEventHandler( "onClientRender", root, function (  ) 
       local x, y, z = getElementPosition( marker ) 
       local Mx, My, Mz = getCameraMatrix(   ) 
        if ( getDistanceBetweenPoints3D( x, y, z, Mx, My, Mz ) <= 15 ) then 
           local WorldPositionX, WorldPositionY = getScreenFromWorldPosition( x, y, z +1, 0.07 ) 
            if ( WorldPositionX and WorldPositionY ) then 
                 dxDrawText ( "Text", WorldPositionX, WorldPositionY, WorldPositionX, WorldPositionY, tocolor(255,255,255,255), 1, "arial" ) 
            end 
      end 
end )

Can u plz post the whole script in the Lua tag so that i can see which line 36 is debugscript referring??
