Method Detail

isPosition3D

protected boolean isPosition3D()

Description copied from class: Poly

Determines whether the position data has a Z component. Must return the same constant value for every instance of the class.

Overriding this method will produce a subclass that is incompatible with a FlexBatch that was instantiated for the superclass type.

Specified by:

isPosition3D in class Poly

isTextureCoordinate3D

protected boolean isTextureCoordinate3D()

Description copied from class: Poly

Determines whether the texture coordinate data has a third component (for TextureArray layers). Must return the same constant value for every instance of the class.

Overriding this method will produce a subclass that is incompatible with a FlexBatch that was instantiated for the superclass type.

Specified by:

isTextureCoordinate3D in class Poly

prepareSharedContext

protected void prepareSharedContext(RenderContextAccumulator renderContext)

Description copied from class: Batchable

Prepares the rendering context for this type of Batchable to be drawn. This method should set state changes that will be the same for all instances of this Batchable type. It must not call begin(), executeChanges(), or end() on renderContext, as these are handled by the FlexBatch. It should not change anything in a way that is unique to any particular instance of this Batchable type.

Overrides:

prepareSharedContext in class Batchable

Parameters:

renderContext - The FlexBatch's manager of GL state changes and texture bindings.

refresh

public void refresh()

Description copied from class: Batchable

Resets the state and default parameters of the Batchable so it can be reused for an entirely new image.

Overrides:

refresh in class Poly

position

public Poly2D position(float x,
                       float y)

Sets the position of the bottom left of the texture region in world space.

Returns:

This object for chaining.

position

public Poly2D position(com.badlogic.gdx.math.Vector2 position)

Sets the position of the bottom left of the texture region in world space.

Returns:

This object for chaining.

rotation

public Poly2D rotation(float rotation)

apply

protected int apply(float[] vertices,
                    int vertexStartingIndex,
                    AttributeOffsets offsets,
                    int vertexSize)

Description copied from class: Batchable

Called by FlexBatch. Applies the Batchable data to the vertex array that will be sent to the Mesh. Overriding this method may produce a subclass that is incompatible with a FlexBatch that was instantiated for the superclass type.

Overrides:

apply in class Poly

offsets - The offsets of the vertex attributes.

vertexSize - The size of a vertex in floats.

Returns:

The number of vertices that were added. The value is unused if this is a Batchable.FixedSizeBatchable, as it is assumed to match Batchable.FixedSizeBatchable.getVerticesPerBatchable().

region

public Poly2D region(com.badlogic.gdx.graphics.g2d.PolygonRegion region)

Description copied from class: Poly

Sets the polygon region.

Overrides:

region in class Poly

Returns:

This object for chaining.

size

public Poly2D size(float width,
                   float height)

Overrides:

size in class Poly

origin

public Poly2D origin(float originX,
                     float originY)

Description copied from class: Poly

Sets the center point for transformations (rotation and scale). For Quad2D, this is relative to the bottom left corner of the texture region. For Quad3D, this is relative to the center of the texture region and is in the local coordinate system.

Overrides:

origin in class Poly

Returns:

This object for chaining.

color

public Poly2D color(com.badlogic.gdx.graphics.Color color)

Overrides:

color in class Poly

color

public Poly2D color(float r,
                    float g,
                    float b,
                    float a)

Overrides:

color in class Poly

color

public Poly2D color(float floatBits)

Overrides:

scale

public Poly2D scale(float scaleX,
                    float scaleY)

Overrides:

scale in class Poly
