Constrcuts a 1x1 rectangle with center located at (0,0).

Constructs a rectangle.

Constructs a rectangle with end points located at aPos and bPos, and width.

Constructs a rectangle.

Returns if the center of this primitive is "above" (in y) in relation to the center of otherPrimitive.

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.

Returns if the center of this primitive is "below" (in y) in relation to the center of otherPrimitive.

Determines if this primitive collides with otherPrimitive.

Determines if this primitive collides with the otherPrimitive. If true, pos is the colliding position.

If visible, draws the primitive with the associated text label.

Draws the Rectangle.

Retruns if the current velocity is non-zero.

Determines if this primitive is in the AutoDrawSet.

Returns if the center of this primitive is "to the left" (in x) in relation to the center of otherPrimtive

Remove this primitive from the AutoDrawSet. After this function call, this primitive will not be drawn in the application window.

Returns if the center of this primitive is "to the right" (in x) in relation to the center of otherPrimitive

aPos and bPos are two end positions on the opposite edges of the rectangle. Width is the width of the edge.

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.

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.

Make sure this primitive is drawn on top of all other primitives.

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

Center of the primitive.

X coordinate of the center position of the primitive.

Y coordinate of the center position of the primitive.

Color of the primitive. (undefined for PrimitiveSet).

Gets or Sets the zero-based current sprite column for sprite sheet drawing.

Gets or Sets the zero-based current sprite row for sprite sheet drawing.

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

Height of the rectangle.

Annotated text label to be associated with the primitive.

Color of the anontated text label.

Lower left corner of the rectangle.

Upper left corner of the primitive.

Lower left corner of the Primitive.

Get or Set the normal direction of the primitive. Setting NormalDirection will update RotateAngle and FrontDirection accordingly.

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

Defines if the primitive should move by its current velocity. Defaults to false.

Get/Set width/height of the primitive.

Width of the primitive.

Height of the primitive. For PrimitiveCircle (diameter), PrimitiveRectangle (height), PrimitiveSet (undefined).

Get/Set the speed (magnitude of the Velocity vector) for the velocity.

Texture file name (without the "." or the extension) to cover the primitive.

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.

Allow the primitive to draw as a sprite sheet.

Allow the primitive to follow a specified sprite sheet animation sequence.

Velocity of a primitive. This is a true velocity: with magnitude (speed) and direction for tavel.

Get/Set the direction of the velocity.

Get/Set the x-component of the primitive velocity.

Get/Set the y-component of the primitive velocity.

Whether the primitive is visible.

Width of the rectangle.
