XNACS1Primitive Members

Center	Center of the primitive.
CenterX	X coordinate of the center position of the primitive.
CenterY	Y coordinate of the center position of the primitive.
Color	Color of the primitive. (undefined for PrimitiveSet).
CurrentSpriteSheetFrameX	Gets or Sets the zero-based current sprite column for sprite sheet drawing.
CurrentSpriteSheetFrameY	Gets or Sets the zero-based current sprite row for sprite sheet drawing.
FrontDirection	Sets the front direction of the primitive. Setting FrontDireciton will cause the RotateAngle and NormalDirection of the primitive to be updated accordingly. y default, when RotateAngle is 0, FrontDireciton points towards (1,0) [positive X-direction]. E.g., if we set RotateAngle to 90-degrees, FrontDireciton will be updated accordinlgy to (0,1) [positive y-direciton], or rotated 90-degress in the anit-clockwise direction
Label	Annotated text label to be associated with the primitive.
LabelColor	Color of the anontated text label.
MaxBound	Upper left corner of the primitive.
MinBound	Lower left corner of the Primitive.
NormalDirection	Get or Set the normal direction of the primitive. Setting NormalDirection will update RotateAngle and FrontDirection accordingly.
RotateAngle	Rotate the primitive by the Angle specified (in degree). After the rotation, the FrontDirection of the primitive will be udpated accordingly. By default, when RotateAngle is 0, FrontDireciton points towards (1,0) [positive X-direction]. E.g., if we set RotateAngle to 90-degrees, FrontDireciton will be updated accordinlgy to (0,1) [positive y-direciton], or rotated 90-degress in the anit-clockwise direction
ShouldTravel	Defines if the primitive should move by its current velocity. Defaults to false.
Speed	Get/Set the speed (magnitude of the Velocity vector) for the velocity.
Texture	Texture file name (without the "." or the extension) to cover the primitive.
TextureTintColor	If a primitive has a texture assigned, this will change the tint and or opacity of the texture when drawn, Color.White is no tint or opacity.
UseSpriteSheet	Allow the primitive to draw as a sprite sheet.
UseSpriteSheetAnimation	Allow the primitive to follow a specified sprite sheet animation sequence.
Velocity	Velocity of a primitive. This is a true velocity: with magnitude (speed) and direction for tavel.
VelocityDirection	Get/Set the direction of the velocity.
VelocityX	Get/Set the x-component of the primitive velocity.
VelocityY	Get/Set the y-component of the primitive velocity.
Visible	Whether the primitive is visible.

Above	Returns if the center of this primitive is "above" (in y) in relation to the center of otherPrimitive.
AddToAutoDrawSet	Add this primitive to the AutoDrawSet. If this primitive already exists in the draw set, this function call is ignored. By default, all primitive are added into the AutoDrawSet.
Below	Returns if the center of this primitive is "below" (in y) in relation to the center of otherPrimitive.
Collided	Overloaded. Determines if this primitive collides with the otherPrimitive. If true, pos is the colliding position.
Draw	If visible, draws the primitive with the associated text label.
HasNonZeroVelocity	Retruns if the current velocity is non-zero.
IsInAutoDrawSet	Determines if this primitive is in the AutoDrawSet.
LeftOf	Returns if the center of this primitive is "to the left" (in x) in relation to the center of otherPrimtive
RemoveFromAutoDrawSet	Remove this primitive from the AutoDrawSet. After this function call, this primitive will not be drawn in the application window.
RightOf	Returns if the center of this primitive is "to the right" (in x) in relation to the center of otherPrimitive
SetTextureSpriteAnimationFrames	Sets animation parameters for a sprite sheet primitive. Zero-based first frame column for the beginning sprite in the animation sequence. Zero-based first frame row for the beginning sprite in the animation sequence. Zero-based first frame column for the ending sprite in the animation sequence. Zero-based first frame row for the ending sprite in the animation sequence. How many ticks the animation will pause for on each frame. The behavior of the animation loop.
SetTextureSpriteSheet	Defines a texture specified for a primitive to behave like a sprite sheet with the specified number of sprites. The default sprite to be drawn is the top left sprite in the sheet. Example: The texture for a given primitive has 16 sprites in it, arranged in a 4 by 4 pattern. By default, all 16 sprites will be displayed, stretched to fit the primitive. Calling this method allows you to specify the number of sprites in the texture. The texture of the sprite sheet to be used. The number of columns in the sprite sheet (number of sprites in a single row). Number of rows in the sprite sheet. The padding between sprites and on the top and left edge.
TopOfAutoDrawSet	Make sure this primitive is drawn on top of all other primitives.
TravelPrimitive	Moves the primitive during each update cycle. This function is automacially called for all visible primitives. Default behavior is to move the primitive if: . Primitive is visible (invivislble primitive is not updated) . ShouldTravel is true . HasNonZeroVelocity() is true

DrawPrimitive

Draws the primitive.

Size	Get/Set width/height of the primitive.
SizeX	Width of the primitive.
SizeY	Height of the primitive. For PrimitiveCircle (diameter), PrimitiveRectangle (height), PrimitiveSet (undefined).
