Detailed Description

This is the glue class between TerrainLoader and ReloadPlane.

Definition at line 24 of file LoaderGlue.h.

Constructor & Destructor Documentation

random_racer::LoaderGlue::LoaderGlue	(	VRS::SO< vrsode::CollisionBody >	collisionBody,
		VRS::SO< TerrainLoader >	loader,
		float	boxSize,
		float	centerDiff,
		VRS::Vector	position = `VRS::Vector(0, 0, 0)`,
		VRS::SO< ItemDistributor >	itemDistributor = `NULL`
	)

Ctor.

Parameters:

	collisionBody	This 'is' the Car and we use its poistion to see where the car currently is at to calculate the new planes.
	loader	The TerrainLoader we tell to replaceTerrain() every time collisionCallback() is called after relocating the planes.
	boxSize	How big the effective box is which the 4 ReloadPlanes build.
	centerDiff	How far away the center points the of the 8 possible next plane locations are from the current center point, setting this to values which are bigger than boxSize / 2.0 makes reloading more efficient because it does happen less often.
	position	Is currently semi-unused.
	itemDistributor	this object distributes collectable items in in our world.

Member Function Documentation

void random_racer::LoaderGlue::relocatePlanesAround	(	double	x,
		double	y
	)			`[private]`

Moves the 4 ReloadPlanes to a new position so that the Car again is in the center of a box.

Here is the caller graph for this function:

void random_racer::LoaderGlue::collisionCallback ( unsigned int planeId )

Gets called if a new collsion happens, this relocates the planes around a calculated new center point and calls replaceTerrain() of the TerrainLoader.

Here is the call graph for this function:

void random_racer::LoaderGlue::registerPlanes ( VRS::SO< ReloadPlane > * planeArray )

Attaches the LoaderGlue to the 4 given ReloadPlanes, sets their normals according to their position in the array and then moves them to their initial position around the car.

Parameters:

planeArray

A C-Array containing 4 SOs of ReloadPlanes.

VRS::SO<VRS::Callback1<unsigned int> > random_racer::LoaderGlue::getCallback ( ) [inline]

Returns the callback object which should get connected to the ReloadPlanes.
