Help Please?

Hey, the errors of this code are; Attemp to call global findRotation 'a nil value'?

  
local xa, ya, za = getElementPosition(marker1) 
local xb, yb, zb = getElementPosition(marker2) 
  
function walking(walking) 
    setElementRotation(johnny, findRotation(xa, ya, xb, ya)) 
    setPedAnimation( johnny, "ped", "WOMAN_walknorm") 
end

you haven't defined findRotation function in first place

as my friend used it, he first needed to define it fully like by getting rotation and calculating it

Define it where?

[iPrestege]

What you mean with "findRotation" you mean getElementRotation ??

[Lloyd Logan]

What you mean with "findRotation" you mean getElementRotation ??

That was mental Castillo that told me that! =D

[iPrestege]

I really did not see this .

[Lloyd Logan]

I really did not see this .

Castillo was right, I need to use findRotation, because i have to find the rotation between to markers!

Any suggestions?

Where is the findRotation function?

[Lloyd Logan]

Where is the findRotation function?

In my script?

findRotation (Function source) must be inside your script.

What do you mean, is that what i have done in the OP?

[manve1]

it's a useful function only, so u are missing out 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 

[TAPL]

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 
  
local xa, ya, za = getElementPosition(marker1) 
local xb, yb, zb = getElementPosition(marker2) 
  
function walking(walking) 
    setElementRotation(johnny, findRotation(xa, ya, xb, ya)) 
    setPedAnimation( johnny, "ped", "WOMAN_walknorm") 
end 

How difficult it is to understand this?

Edit:

Also setElementRotation required 3 arguments, while findRotation return one argument only.

[Castillo]

He can just use setPedRotation, which is for this kind of thing.

[Lloyd Logan]

Sorry for my ignorance, but the player is now going in a different direction between the two markers?

[Castillo]

Try setting just the rotation, to see if it rotates right.

If that doesn't work, try adding -90 on the rotation.

Thanks Castillo! I had to +90 on the rotation!

You're welcome.
