Hello,

how do set the angle to a object.

PHP Code:

Matrix mCam=Cameras[cameraID].matrix();
   mCam.orn().rotateY(Players[0].angle.y);
   mCam.normalize(); 
   Cameras[cameraID].matrix(mCam); 

When i do this, my objekts rotate ever.

PHP Code:

Matrix mCam;
   SetMatrix(matrix());
   SetMatrix(mCam);
   mCam=matrix();
   mCam.orn().setRotateY(pplayer.angle.x);
  
   mCam.normalize();
   if (drawMatrix)DrawMatrix();    
   matrix(mCam); 

wehen i do this i have a wrong Direction

when i set the Direction Down. I have no Rotate whats wrong

PHP Code:

Matrix mCam;
   SetMatrix(matrix());
   SetMatrix(mCam);
   mCam=matrix();
   mCam.orn().setRotateY(pplayer.angle.x);
   
   mCam.orn().setOrient(DIRE_DOWN);
   
   mCam.normalize();
   if (drawMatrix)DrawMatrix();    
   matrix(mCam);

Hello,

I have the solution but i think is a bug when i write this code failt the rotation in Y.

PHP Code:

Matrix mCam;
   SetMatrix(mCam);
   mCam.orn().setRotateY(pplayer.angle.x);   
   mCam.orn().setRotateX(DegToRad(90.0));
   mCam.normalize();
  
   SetMatrix(matrix());
   matrix(mCam); 

When i write this, it works

PHP Code:

Matrix mCam;
   SetMatrix(mCam);
   mCam.orn().setRotateXY(DegToRad(90.0),pplayer.angle.x);
   mCam.normalize();
  
   SetMatrix(matrix());
   matrix(mCam); 

Greetings Denis

All set* methods reset the matrix before appying the transformation. That is why the Y rotation does not work in the first example, but works in the second example. For more details, please read the comments in the header files using the Header Browser tool or in Visual Studio.

Hello,

I think not. I have the same Problem without SetMatrix.

Greetings Denis

over the set methode Declaration have found this :-)
// set (set methods reset the full matrix)
ok now i have understand you all set* methode, Thanks

This is my correct solution,TANKS

PHP Code:

SetMatrix(mCam);
   mCam.orn().setOrient(DIRE_DOWN);
   mCam.orn().rotateY(pplayer.angle.x);
   mCam.normalize();
  
   SetMatrix(matrix());
   matrix(mCam); 

Greeting Denis
