Constructor & Destructor Documentation

CObject::CObject ( void )

Create a CObject class object with default parameters.

Definition at line 674 of file structs.cpp.

CObject::CObject	(	int	typeID,
		CWorld *	ThisWorld
	)

Creates a CWorld class object, specifying the objects type via the iType member, and the world to which this object will belong using the ParentWorld member.

Member Function Documentation

int CObject::Draw ( void )

Draw this object on the screen, based on the object's member data. If enabled, draw a bounding box around the object to help visualize the boundary used for collision-detection.

Here is the call graph for this function:

Here is the caller graph for this function:

void CObject::StartAnimating ( void )

Set the object's animation flag so that the animation routines update this object, advancing it's frame based on the objects delay variable. The drawing routines will now draw this object's current animation frame.

Definition at line 1011 of file structs.cpp.

References bAnimating, iAnimTimeStamp, iCurrentFrame, CWorld::iCurrentTime, and ParentWorld.

void CObject::StopAnimating ( void )

Set the object's animation flag so that the animation routines ignore this object. The drawing routines will now draw this object's normal texture.

Definition at line 1024 of file structs.cpp.

References bAnimating.

void CObject::SetBB	(	float	left,
		float	right,
		float	bottom,
		float	top
	)

The parameters passed to this function represent lines defining the extents of the bounding box surrounding this object. For example, the fBBTop member defines the y-coordinate of the line defining the top of this objects bounding box.

Definition at line 1037 of file structs.cpp.
