class TextureAttribute

Defined in: C4Attributes.h

The TextureAttribute class is the base class for attributes that use a texture map.

Definition

class TextureAttribute : public Attribute

Member Functions

`TextureAttribute::GetTextureName`	Returns the name of the texture map.
`TextureAttribute::GetTexture`	Returns the texture map object.
`TextureAttribute::SetTexture`	Sets the texture map object.
`TextureAttribute::GetTextureBlendMode`	Returns the texture blend mode.
`TextureAttribute::SetTextureBlendMode`	Sets the texture blend mode.

Constructor

TextureAttribute(AttributeType type, const char *name);

TextureAttribute(AttributeType type, Texture *texture);

TextureAttribute(AttributeType type, const TextureHeader *header, const void *image = nullptr);

The constructors have protected access. The TextureAttribute class can only exist as the base class for other material attribute classes that use texture maps.

Parameters

`type`	The attribute type. This must be the type of a subclass that inherits from `TextureAttribute`.
`name`	The name of the texture map to load.
`texture`	The texture object to use. Specifying this parameter increments the reference count of the texture object.
`header`	A texture header from which to construct a new texture object.
`image`	A pointer to a texture image that is used if the texture header does not specify an offset to an image.

Description

The TextureAttribute class encapsulates information about a texture map for other material attributes. If a TextureAttribute object is constructed by passing the name parameter, then the texture map is loaded through the Resource Manager. If a TextureAttribute object is constructed by passing the header and image parameters, then a new texture map is constructed using the information in the TextureHeader structure. If the image parameter is not nullptr, then the texture image is read from the location to which it points; otherwise, the texture header specifies the location of the image.
