Constructor & Destructor Documentation

LogicalScene()

LogicalScene::LogicalScene

(

int

n

)

Builds a logical scene where collisions are detected by checking n random points within shapes.

Parameters

n	any positive integer.

  : nb_tested( n ) {}

Member Function Documentation

intersect() [1/2]

bool LogicalScene::intersect

(

MasterShape *

f1

)

Parameters

f1	any master shape.

Returns

'true' iff it collides with a different master shape stored in this logical scene.

Definition at line 202 of file objects.cpp.

{
  for ( auto f : formes )
    if ( ( f != f1 ) && intersect( f, f1 ) )
      return true;
  return false;
}

intersect() [2/2]

bool LogicalScene::intersect	(	MasterShape *	f1,
		MasterShape *	f2
	)

Given two shapes f1 and f2, returns if they collide.

Parameters

f1	any master shape.
f2	any different master shape.

Returns

'true' iff they collide, i.e. have a common intersection.

Definition at line 190 of file objects.cpp.

{
  for ( int i = 0; i < nb_tested; ++i )
    {
      if ( f2->isInside( f1->randomPoint() )
           || f1->isInside( f2->randomPoint() ) )
        return true;
    }
  return false;
}
