Client-side

                local angle = math.deg(math.atan2(X/Y)) 
                    if ( x > fx ) and ( y > fy ) then 
                        angle = 90 - angle 
                    elseif ( x > fx ) and ( y < fy ) then 
                        angle = 270 + angle 
                    elseif ( x < fx ) and ( y > fy ) then 
                        angle = 90 + angle 
                    elseif ( x < fx ) and ( y < fy ) then 
                        angle = 270 - angle 
                        setElementRotation( arrestedcriminal, angle ) 
                    end 
                    end 
                    end 
addEventHandler("onPlayerArrested",getRootElement(),cuffed) 

Server-side

  
function arrest(arrester,nightstick) 
    if getPlayerTeam(arrester) == getTeamFromName("Police") or getTeamFromName("Speed Enforcement") then 
        if nightstick == 3 then 
            outputChatBox("weapon value correct")         
            if getPlayerWantedLevel(source) > 0 then       
            arrestedcriminal = source     
            if triggerClientEvent(source,"onPlayerArrested",source,source) == true then 
            outputChatBox("clientside event triggered")   
                end         
            end 
        end 
    end 
end 
            
addEventHandler("onPlayerDamage",getRootElement(),arrest) 

Hey so I wrote this script for after a player being arrested he is forced to follow the police, but it doesn't work. No error is showed, i tried to use outputchatbox to see i found out the server side seems good, please help me :|

Try this :

function followPolice(thecop, theprisoner) 
    if (isPedInVehicle(theprisoner)) then return end 
        local copx, copy, copz = getElementPosition (thecop) 
        local prisonerx, prisonery, prisonerz = getElementPosition (theprisoner) 
        copangle = (360 - math.deg (math.atan2 ((copx - prisonerx), (copy - prisonery)))) % 360 
        setPedRotation(theprisoner, copangle) 
        setCameraTarget(theprisoner, theprisoner) 
        local dist = getDistanceBetweenPoints2D (copx, copy, prisonerx, prisonery) 
  
      --Your code here  
     end

TY for answering but still not working :|

I did it like this, but its still not working :| , by the way what is %360 ?

function cuffed(arrester,source)  
function cuffed(arrester)  

Never define a source variable as a parameter.

  
11 % 10 = 1 
21 % 10 = 1 
55 % 10 = 5 
53673465 % 10 = 5 
  
390 % 360 = 30 
721 % 360 = 1 
  
Rest value = % 

Hey but in this case "source" is not really the source but is a parameter i passed down by "triggerClientEvent()", and also will what will 30 % 360 give me and -30 % 360 give me? :) thanks for help

30 % 360 = 30.

You still didn't understand: % = get the rest of the division. It's actually called 'modulo'.

30 % 360 = 30 because 360 > 30, that means the rest is the actual divided number.

For your understanding:

721 % 360 = 1. Why ? 721 / 360 = 2, rest = 1 => 721 = 360 * 2 + 1.

These are all basic mathematical operators. You should have had a basic understanding about it before even touching Lua.

Hey but in this case "source" is not really the source but is a parameter i passed down by "triggerClientEvent()",

It is automatic defined, so don't have to write it down as parameter, or you will overwrite the source variable which will becomes useless.

  
triggerClientEvent( 
source, -- = sending to 
"onPlayerArrested", -- event 
source, -- = source 
  
arrester, -- = first parameter 
whatEver, -- = second parameter 
whatEver2 -- = third parameter 
----------------------------------------------------------------------------------------------------------- 
triggerClientEvent(source,"onPlayerArrested",source,arrester,whatEver,whatEver2) 

>

addEvent("onPlayerArrested",true) 
function cuffed(arrester,whatEver,whatEver2)  
    local mySource = source 
end 
addEventHandler("onPlayerArrested",getRootElement(),cuffed)
