Problem with circle generator.

otto-san:

I misunderstood.

It does round the player's position.


EDIT:

I can think of multiple ways to probably do this but I don't know how to exactly do any of them.

So to retain most of what can be done with this right now, how can I get the position of a player's temporary brick?

phflack:

you could just use it to start off the movement of your brick, instead of moving it to a specific location

Red_Guy:

This seems to work -- but its a bit laggy when the circles get big

--- Code: ---function Player::dobrickstuff(%player, %pos, %datablock)
{
        %playerPos = %player.tempBrick.getPosition();
        %position = vectorAdd(%playerPos, %pos);
        %brick = new fxDTSBrick()
        {
                client = %player.client;
                datablock = %datablock;
                position = %position;
                rotation = "0 0 0 0";
                colorID = %player.client.currentColor;
                scale = "1 1 1";
                angleID = "0";
                colorfxID = "0";
                shapefxID = "0";
                isPlanted = 1;
                stackBL_ID = %player.client;
        };
        %brick.setTrusted(1);
        %brick.plant();
        %player.client.brickGroup.add(%brick);
}

function makeEllipse(%player, %r1, %r2, %scale, %addedZ)
{
  %steps = (3.14159265 * %r1 * %r1) / 0.5;
  %inc = 360 / %steps;
  echo("%r1: " @ %r1 @ " steps: " @ %steps @ " inc: " @ %inc);



        if(%r2 > 0)
        {
                for(%i = 0; %i < 360; %i+= %inc)
                {
                        %x = %r1 * mFloatLength(mCos(mRadToDeg(%i)), 6);
                        %y = %r2 * mFloatLength(mSin(mRadToDeg(%i)), 6);
                        %player.doBrickStuff(%x SPC %y SPC 0 + %addedZ, Brick1x1Data);
                }
        }
        else
        {
                for(%i = 0; %i < 360; %i+= %inc)
                {
                        %x = %r1 * mFloatLength(mCos(mRadToDeg(%i)), 6);
                        %y = %r1 * mFloatLength(mSin(mRadToDeg(%i)), 6);
                        %player.doBrickStuff(%x SPC %y SPC 0 + %addedZ, Brick1x1Data);
                }
        }
}


function serverCmdMakeCircle(%client, %r1, %r2)
   {
    if ( !isObject(%client.player.tempBrick) )
      {
       messageClient(%client, '', "place a ghost brick first");
       return;
      }
    makeEllipse(%client.player , %r1, %r2, 0);
   }

function serverCmdCircleTest(%client)
   {
    for ( %a=5; %a < 50; %a+=4)
      {
       serverCmdMakeCircle(%client, %a, %a);
      }
   }

--- End code ---

and it really only works properly when %r1 = %r2
to fix -- consult your math book and lookup the formula for the circumference of an ellipse, then adjust the forumla accordiingly.

the magic number here is 0.5 - the width of a 1x1 brick.

place a brick and type  /circletest to see it in action
