Element rotation

[IIYAMA]

I am looking for findRotation math, but one that is also returning X and Y rotation.

https://wiki.multitheftauto.com/wiki/FindRotation

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 

[K4stic]

use this:

( 360 - math.deg ( math.atan2 ( ( x - px ), ( y - py ) ) ) ) % 360 
  
example: 
x, y, z = getElementPosition( player ) 
px, py, pz = getElementPosition( player2 ) 
local rotation = ( 360 - math.deg ( math.atan2 ( ( x - px ), ( y - py ) ) ) ) % 360 
  

[IIYAMA]

use this:

( 360 - math.deg ( math.atan2 ( ( x - px ), ( y - py ) ) ) ) % 360 
  
example: 
x, y, z = getElementPosition( player ) 
px, py, pz = getElementPosition( player2 ) 
local rotation = ( 360 - math.deg ( math.atan2 ( ( x - px ), ( y - py ) ) ) ) % 360 
  

and how do I get the X and Y rotation?

Because now I also only have the Z rotation.

[K4stic]

z it's just up or down they not used as rotation thing

It is.

1 think we talk about MTA physics not Real life so try my code

to get rotation you can use SetElementRotation( blabla, rotation ) or return rotation

@ CastielRecords

I didn't make this topic for things I already know, I asked about getting the X and Y rotation based on finding rotation.

Next to that I have lots lua experience with lua, but I don't have with 3D math.

Thanks for trying to help me, but I need somebody with high math skills.

Is there anybody who can help me with this?

What exactly are you going to use it for? depending on what, you cant get X rotation, only Z and Y.

If you can get the Z rotation, you can also get the X and Y rotation. It's just math with sins, cons and tans.

sins, cos and tan isn't JUST this math. I know how they work, but I don't know how to use them with this.

Since my brain can't merge the ordinary math with 3D math......

Pls give me a sample, if it is just sin cos and tan.

Check your PM.

For example if you are using two points as reference, like in the 'findRotation' function that IIYAMA provided, then you can only get Z and Y rotation. You need at least three points to get roll (X rotation) also, otherwise roll can only be 0.

Pitch / Yaw ( Y , Z ) roation is prity simple to calculate

It's not coded in LUA , it's C++ , i just C+P it from my old aimbot used in some FPS game's , but the math is the same just need to be recoded to LUA.

  
  
            D3DXVECTOR3 NewVector; 
            NewVector.x = pClientInfo->g_pLocal->Pos.x - g_pESP.pPlayers[AimAt].Aimcords.x; 
            NewVector.y = pClientInfo->g_pLocal->Pos.y - g_pESP.pPlayers[AimAt].Aimcords.y; 
            NewVector.z = pClientInfo->g_pLocal->Pos.z - g_pESP.pPlayers[AimAt].Aimcords.z; 
  
            float CamYaw = (float)atanf(NewVector.x/NewVector.z); 
            if(NewVector.z > 0.0f && NewVector.x < 0.0f && CamYaw < 0.0f) 
                CamYaw += D3DX_PI; 
            else if(NewVector.z > 0.0f && NewVector.x > 0.0f) 
                CamYaw += D3DX_PI; 
  
            DWORD tempKey = 0; 
            switch(AimbotKey) 
            { 
                default: 
                    tempKey = VK_LBUTTON; 
                break; 
            
                case 1: 
                    tempKey = VK_RBUTTON; 
                break; 
                
                case 2: 
                    tempKey = VK_SHIFT; 
                break; 
            } 
            if((GetAsyncKeyState(tempKey) && !Aimbotkeyon) || (Aimbotkeyon)) 
            { 
                pClientInfo->g_pLocal->pitch    = (float)atan2f(NewVector.y,(float)sqrt(pow(NewVector.z,2) + pow(NewVector.x,2))); 
                pClientInfo->g_pLocal->yaw      = CamYaw;

what is Pitch and Yaw in lua?

Can you explain a bit more, because I sorry but I have no idea how this is working.

In 3D world / plan is Pitch / Yaw / Roll. They are the 3 axis rotation. Pitch = Y rot , Yaw = Z rot , Roll = X rot.

In MTA for a better understanding they call'd them X,Y,Z rot , but in game coding they are call'd Pitch / Yaw / Roll and most of the time they are used on the Camera , Pitch / Yaw is look up-down , left-right , and Roll is used to tilt the camera in MTA one exemple would be the "drunk camera" where it get shake'd.

And even now i can't imagine where you wanna use them.

function findPitch(camerax,cameray,cameraz,pointx,pointy,pointz) 
  
local dX=camerax-pointx 
local dY=cameraz-pointz 
local dZ=cameray-pointy 
  
local pitch=math.atan2(dY,math.sqrt(math.pow(dZ,2) + math.pow(dX,2))); 
return pitch 
end 

Converted from bandi's code, already sended to IIYAMA via skype, I just felt of sharing it. And I don't think that Roll is needed. Also it's returned in radians here's the code for converting it to degrees:

local degree = pitchReturn*(180/math.pi) 

pitchReturn = the return of the function "findPitch", it was just a simple google

[IIYAMA]

Danny, thank you very much! It works great!

Bandi thanks for explaining about the camera rotation.

It seems it didn't needed the Y rotation after all.

Also thanks to everybody that replied on this topic.
