setElementRotation

[Drakath]

What's the magic formula to make a ped look at localPlayer with setElementRotation?

[Walid]

Try to use :

setCameraMatrix()

Try to use :

setCameraMatrix() 

You did not understood me.

This makes a ped look at you: setPedRotation(ped, (360 - math.deg(math.atan2((x - px), (y - py)))) % 360)

I want the same result using setElementRotation

Start by looking at the syntax:

setPedRotation( thePed, z ) 
setElementRotation( thePed, x, y, z ) 

You need to provide x and y rotations as well which logically should be the same as they where before you changed the z rotation, so to get x and y, simply use:

local rx,ry,rz = getElementRotation( thePed ) 

Argument 1 and 4 will be the same as 1 and 2 in setPedRotation while 2 and 3 will get the values from rx and ry.

Thanks for posting the obvious part but can you apply the mathematical functions to those arguments?

[Mr_Moose]

How hard could it be, you already posted the old working code, you need to write this:

setPedRotation(ped, (360 - math.deg(math.atan2((x - px), (y - py)))) % 360) 

as:

local rx,ry,rz = getElementRotation( ped ) 
setElementRotation(ped, rx, ry, (360 - math.deg(math.atan2((x - px), (y - py)))) % 360) 

Keep the rest of the code as it is, I assume that x,px,y,py are position coordinates.

Thanks, I didn't notice any changes in my pedestrians but I guess my script is more efficient now.

[Mr_Moose]

The main reason to upgrade is because the old function setPedRotation is deprecated, that means it'll be removed in future versions. You'll do this change mainly to prevent your resources from stop working after a future update that removes the old function.

If this is still not resolved then you might want to look at this useful function:
