Camera Speed
Hi Folks,

I'm trying to set the default camera speed, but somehow i'm not getting it. Here's what i do:

camera starts with following values:
Code:
Cam.dist =10;
   Cam.yaw  =-PI_4;
   Cam.pitch=-0.5;
   Cam.at.set(2,8,2);

camera-controls:
Code:
// Kamera aktualisieren
   {
      if(Kb.b(KB_A    ))Cam.matrix.pos-=Cam.matrix.x*Tm.d();
      if(Kb.b(KB_D    ))Cam.matrix.pos+=Cam.matrix.x*Tm.d();
      if(Kb.b(KB_W    ))Cam.matrix.pos+=Cam.matrix.z*Tm.d();
      if(Kb.b(KB_S    ))Cam.matrix.pos-=Cam.matrix.z*Tm.d();
      if(Kb.b(KB_SPACE))Cam.matrix.pos+=Cam.matrix.y*Tm.d();
      if(Kb.b(KB_LCTRL))Cam.matrix.pos-=Cam.matrix.y*Tm.d();
      if(Ms.hidden())
      {
         Cam.yaw  -=Ms.dir_d.x;
         Cam.pitch+=Ms.dir_d.y;
      }
      Cam.setAngle(Cam.matrix.pos,Cam.yaw,Cam.pitch).updateVelocities().set();
   }

Is there a possibility to set the default Camera Speed ? I've checked the examples and the Doc but nothing found so far. Thanks!

Re: Camera Speed
Well, i'm not a programmer, and my knowledges about maths goes to multiply and so, but i think you could do:

Code:
{
      Int speed = 10; //For example
      if(Kb.b(KB_A    ))Cam.matrix.pos-=Cam.matrix.x*Tm.d() * speed;
      if(Kb.b(KB_D    ))Cam.matrix.pos+=Cam.matrix.x*Tm.d() * speed;
      if(Kb.b(KB_W    ))Cam.matrix.pos+=Cam.matrix.z*Tm.d() * speed;
      if(Kb.b(KB_S    ))Cam.matrix.pos-=Cam.matrix.z*Tm.d() * speed;
      if(Kb.b(KB_SPACE))Cam.matrix.pos+=Cam.matrix.y*Tm.d();
      if(Kb.b(KB_LCTRL))Cam.matrix.pos-=Cam.matrix.y*Tm.d();
      if(Ms.hidden())
      {
         Cam.yaw  -=Ms.dir_d.x;
         Cam.pitch+=Ms.dir_d.y;
      }
      Cam.setAngle(Cam.matrix.pos,Cam.yaw,Cam.pitch).updateVelocities().set();
   }

I'm didn't tested, but i think it's ok

PS: And for yaw and pitch, well , do the same xD. I think some one could help you if i didn't.
