GetSpeed() not working?

[G3bE]

I tried to print out the users speed with both GetSpeed().x/y/z and GetSpeedX/Y/Z() and it just send me nulls. Is there anything I should know for using this function? Here is my onPlayerMoving() code:

1 2 3

function OnPlayerMoving(Player)  Player:SendMessageInfo('Speed X:' .. Player:GetSpeed().x) end

The hook is the same as in "Writing a Cuberite plugin" in the registering hook part.(link postet as a reply)

Does it send 'nil' values or the actual number 0?

In the code above it's sending me the number 0, but in this code (yes, it is an anti cheat and I know that somebody else is doing this already)

it is sending me this error:

Code:

Warning: [23:03:44] LUA: Plugins/RAW_ac/checks/movement.lua:5: attempt to call method 'GetSpeedX' (a nil value)

and the same comes for IsSprinting() if I set speed to 1 manually.
Hope that this helps.

Since nobody is answering me, I decided to make an extra class for the GetSpeed() function that stores the current position and the position a second ago. So, for everyone having the same problem as me; here is the class.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53

require "classes.class"   rawPlayer = class(   function(self, uuid, currPosX, currPosY, currPosZ)     self.uuid = uuid     self.currPosX = currPosX     self.currPosY = currPosY     self.currPosZ = currPosZ     self.lastTime = os.clock()   end )   function rawPlayer:setPos(posX, posY, posZ)   if lastTime < os.clock then     self.lastPosX = self.currPosX     self.lastPosY = self.currPosY     self.lastPosZ = self.currPosZ           self.currPosX = posX     self.currPosY = posY     self.currPosZ = posZ   end end   function rawPlayer:GetSpeedX()   speedX = self.currPosX - self.lastPosX       if speedX < 0 then     speedX = speedX * (-1)   end     return speedX end     function rawPlayer:GetSpeedY()   speedY = self.currPosY - self.lastPosY       if speedY < 0 then     speedY = speedY * (-1)     end       return speedY end       function rawPlayer:GetSpeedZ()   speedZ = self.currPosZ - self.lastPosZ       if speedZ < 0 then     speedZ = speedZ * (-1)   end       return speedZ end

and the 'class()' (skidded from here)

Sorry, I completely forgot to respond back. Next time you can bump the thread when nobody responds.

Does cPlayer:GetSpeed() work? I believe we had a change not too long ago where most XYZ functions were replaced with a single method that accepts a Vector. Perhaps something went wrong while trying to remain compatible with the XYZ methods.

no it is still not working

[NiLSPACE]

But what does it return?

But what does it return?

It returns a 0, but in a more advanced code like my first answer says it gives me an error.

[NiLSPACE]

That's really strange as GetSpeed isn't supposed to return a number at all. It should return a Vector3d which contains 3 numbers (x, y, z). Do you have the complete codebase somewhere online so I could try it?
