How to set a ped facing a player?

[bamby12]

is it possible to make a ped face a player using setPedRotation?

what im trying to do is make a ped spawn in front of a player then face him.

This should work, thanks.

EDIT: ok im trying to createped with a timer and make the ped face the player, heres the code i used.

  
function peds() 
local x, y, z = getElementPosition ( source ) 
local target = createPed(math.random(0,150), x+5, y, z) 
  
    if not target then 
        outputChatBox("Invalid player", player) 
    end 
  
    local x,y,z     = getElementPosition(target) 
    local tx,ty,tz  = getElementPosition(player) 
  
    setPedRotation(target, findRotation(x,y,tx,ty) ) 
   end 
  

i get 2 errors, bad argument @ getelementposition

and

attempt to perform arithmetic on local 'x' a nil value

any help appreciated guys.

both your errors are caused by invalid source variable. (and why are you using source AND player variable?)

where is the code that calls this function?

[bamby12]

  
function enterVehicle ( theVehicle, seat, jacked )  
        outputChatBox ( "You sit in the car and suddenly feel extremely drunk!", source )  
    end 
addEventHandler ( "onPlayerVehicleEnter", getRootElement(), enterVehicle )  
  
function peds() 
local x, y, z = getElementPosition ( source ) 
local target = createPed(math.random(0,150), x+5, y, z) 
  
    if not target then 
        outputChatBox("Invalid player", player) 
    end 
  
    local x,y,z     = getElementPosition(target) 
    local tx,ty,tz  = getElementPosition(player) 
  
    setPedRotation(target, findRotation(x,y,tx,ty) ) 
   end 
  

thats the full code.

[Aibo]

well that part has nothing to do with peds() function.

it cant be the full code, since peds() function is never called in this code, so you cant possibly have those errors shown.

[bamby12]

Ok you got me this is the full code:

  
function enterVehicle ( theVehicle, seat, jacked )  
        outputChatBox ( "You sit in the car and suddenly feel extremely drunk!", source ) 
        cheesetime = setTimer(peds, 2000) 
       --add effects after, this is what i tried to delete seeing as you dont need it. 
    end 
addEventHandler ( "onPlayerVehicleEnter", getRootElement(), enterVehicle )  
  
function peds() 
local x, y, z = getElementPosition ( source ) 
local target = createPed(math.random(0,150), x+5, y, z) 
  
    if not target then 
        outputChatBox("Invalid player", player) 
    end 
  
    local x,y,z     = getElementPosition(target) 
    local tx,ty,tz  = getElementPosition(player) 
  
    setPedRotation(target, findRotation(x,y,tx,ty) ) 
   end

function enterVehicle ( theVehicle, seat, jacked ) 
        outputChatBox ( "You sit in the car and suddenly feel extremely drunk!", source ) 
        cheesetime = setTimer(peds, 2000,0,source) 
       --add effects after, this is what i tried to delete seeing as you dont need it. 
    end 
addEventHandler ( "onPlayerVehicleEnter", getRootElement(), enterVehicle ) 
  
function peds(player) 
local x, y, z = getElementPosition ( player ) 
local target = createPed(math.random(0,150), x+5, y, z) 
  
    if not target then 
        outputChatBox("Invalid player", player) 
    end 
  
    local x,y,z     = getElementPosition(target) 
    local tx,ty,tz  = getElementPosition(player) 
  
    setPedRotation(target, findRotation(x,y,tx,ty) ) 
   end 

Should work.

still get the same errors on line 9. and 10.

[Castillo]

copy the last code, i've found a error and edited it.

[bamby12]

Thanks that worked kind of, the peds spawn but they dont face me, error: attempt to call global 'findRotation'

[Aibo]

well findRotation is not a built-in MTA function, you need to add it to your script to use it.

[bamby12]

i dont understand Aiboforcen?

[Aibo]

add this

  
function findRotation(x1,y1,x2,y2) 
  local t = -math.deg(math.atan2(x2-x1,y2-y1)) 
  if t < 0 then t = t + 360 end 
  return t 
end 
  

to your script

Works thank you!! one more question, do i use animations to make the peds walk?
