Help Needed in Trigonometry ...

[s0rcier]

Well codes below is raped from mq2move utils circle command, it's work great while your circling clockwise foward, good for bard kiting, but for my zerker i want to be able to circle backward, facing mobs all the time going anti-clockwise around the circle, and well this functions doesnt do the jobs ... work partially for a while ...

Code: Select all

   double heading; 
   double CircleRadius = 25.0f;
   double X =PcX-CircleX; 
   double Y =PcY-CircleY; 
   double distance=sqrt(X*X + Y*Y); 
   if (distance>(CircleRadius*(2.0/3.0))) { 
      heading=atan2(PcY - CircleY, CircleX - PcX) * 180.0f / PI + 90.0f; 
      heading += 90.0f * (CircleRadius/distance); 
      heading *= 512.0f/360.0f; 
      if( heading >= 512.0f ) heading -= 512.0f; 
      if( heading < 0.0f ) heading += 512.0f; 
   } 

dont know if someone could help or have some solutions, i presume that this circle routine heading was not design at all for what i need at all ... i really wish if someone could help on this finding problems and giving a solutions ... or could at least better explains the problems ... if you want to simulate problems fast use mq2moveutils, /circle on 25 and press down the back keys .... you will find what i means ..

Is that the original code or your modified code?

[s0rcier]

Well modified or mines ... 99% identical to mq2moveutils codes ... if you find flaw in mq2move utils you will find flaw in this one too

here is the moveutils code

Code: Select all

   double X = pChSpawn->X - CircleX; 
   double Y = pChSpawn->Y - CircleY; 
   distance = sqrt(X*X + Y*Y); 

   if (distance>(CircleRadius*(2.0/3.0))) { 
      heading=atan2(pChSpawn->Y - CircleY, CircleX - pChSpawn->X) * 180.0f / PI + 90.0f; 
      heading += 90.0f * (CircleRadius/distance); 
      heading *= 512.0f/360.0f; 
      if( heading >= 512.0f ) heading -= 512.0f; 
      if( heading < 0.0f ) heading += 512.0f; 
      if( bDrunken ) { 
         gFaceAngle = (float)heading; 
      } else { 
         pChSpawn->Heading = (float)heading; 
      } 
   } 

Like i said this works nice if you try to circle clockwise with foward key press ... but dont break when pressing down the back key (and moving backward istead) ...

If you are looking to basically kite behind a mob meleing then trying to get your timers rights between the two comps will be a huge pain, may i suggest that you just modify follow.mac to suit your needs, distance paramateres is pretty obvious. Its a very simple loop, so adding /doabilities and /attack on is extreemely simple.

[dont_know_at_all]

I'm not sure what you are asking. You can't face the mob, run backwards, and circle at the same time.

[Night Hawk]

Well if your running backwards, in a circle motion, your kind of already facing the mob.... right?

"Anti-clockwise" that made me laugh

[dont_know_at_all]

"kind of" is not really very trigonometrical.

[TheUnholy]

Can you say "Anti-clockwise" and "Trigonometry" in the same post? I think that defies certain laws.

[aChallenged1]

Only if you apply the Cowbell to it properly.

[s0rcier]

Well just try with mq2move utils, start a 50 radius circle and hold down the foward key ... you will circle foward ... stop and hit down the back key and you will see that you actually circling for a while but at a point it break up ... pretty sure it's just something easy ... just that i can't point it out atm ...

Well thx for your cooperation, and sorry i didnt spill it right correctly ;P

[dont_know_at_all]

change

Code: Select all

 heading += 90.0f * (CircleRadius/distance);

to

Code: Select all

 heading += 90.0f * (distance/CircleRadius);

[s0rcier]

Well i give up will just hard code my circle at my prefered kyte spot rofl ... thx guys

[MrSmallie]

If you're trying to circle kite a mob to throw ranged attacks at him...good luck...whether clockwise, or counter, forward or back.

If you're going to hardcode something for your prefered location, I suggest a double parallelogram pattern if yuo're the one with agro. If you don't have agro, just use the follow.mac.
