Need help rotating an object around an arbitray point.

Hello Everyone,

When I try to rotate a object around an arbitrary point using either one of these methods I found on the forms the image just sits there and hops back and forth. I could really use any help that I could get figuring out why this is happening. I am setting it to rotate at about 3 degrees every second as time passes. Please any insight is helpful. below are the 2 formulas being used by me. I only ran one method at a time incase you were wondering.


function Harpoon::RotateAroundPlayer(%this, %point, %angle)
{

///////////This was method 1//////

//shift x and y relative to 0,0 origin
%offsetX = (%this.getPositionX() + %point.X* -1);
%offsetY = (%this.getPositionY() + %point.Y* -1);

%rotationRadians = mDegToRad(%angle);

//get distance from origin to source point
%r = t2dVectorDistance(%this.getPosition(), %offsetX SPC %offsetY);

//get current angle of orientation
%theta = mAtan(%offsetY, %offsetX);

// add rotation value to theta to get new angle of orientation
%offsetTheta = %theta + %rotationRadians;

//calculate new x coord
%rotateX = %r * mCos(%offsetTheta);

//calculate new y coord
%rotateY = %r * mSin(%offsetTheta);

//shift new x and y relative to base point
%rotateX = (%rotateX + %point.X);
%rotateY = (%rotateY + %point.Y);

//return new point
%this.setPosition(%rotateX SPC %rotateY);



////////This was method 2///////////

////Get the amount to rotate our object
//%rotation = mDegToRad(%angle); //- %this.getRotation());


////Get the point to rotate our object around
%reffPivotPoint = %this.getWorldPoint(%point);
//Calculate the offset between the point we are rotating about and this object
%reffOffset = VectorSub(%Point, %this.getPosition());
//get the length of our offsets vector
%reffDistance = VectorLen(%reffOffset);
//Get our rotation after our offset has been accounted for
%reffRotationOffset = mAtan(%reffOffset.X, %reffOffset.Y) - %rotation;
//Get the new position for our object
%newPosition = %reffDistance * mSin(%reffRotationOffset) SPC %newPosition = %reffDistance *
mCos(%reffRotationOffset);
//Add our objects piviot point to the new position
%newPosition = VectorAdd(%newPosition, %point);
//Set our objects new position
%this.setPosition(%newPosition.X, %newPosition.Y);
//Set our objects rotation
%this.setRotation(%angle);
