## Detailed Description

Generic superclass for procedural textures.

This class takes care of scheduling when a procedural texture needs updating.

Definition at line 61 of file proctex.h.

## Member Function Documentation

virtual void csProcTexture::Animate | ( | csTicks | current_time | ) | `[pure virtual]`

Animate this texture.

Subclasses of csProcTexture must implement this to implement some kind of animation on the procedural texture.

Implemented in csProcAnimated.

virtual iTextureWrapper* csProcTexture::Clone | ( |  | ) | const`[protected, virtual]`

Create a clone this texture wrapper, using the same texture handle.

Implements iTextureWrapper.

void csProcTexture::DisableAutoUpdate | ( |  | ) | `[inline]`

Disable auto-update.

By default csProcTexture will register a callback so that every time the texture is visible Animate will automatically be called. If you don't want this and you want to call Animate on your own then you can disable this feature. You need to call DisableAutoUpdate() before calling Initialize().

Definition at line 153 of file proctex.h.

virtual bool csProcTexture::GetAlwaysAnimate | ( |  | ) | const`[protected, virtual]`

Get the 'always animate' flag.

Implements iProcTexture.

virtual void csProcTexture::GetDimension | ( | int & | w,
|  | int & | h |
| ) |  |  | const`[inline, virtual]`

get dimension

Definition at line 201 of file proctex.h.

virtual iTextureFactory* csProcTexture::GetFactory | ( |  | ) | `[protected, virtual]`

Returns the texturefactor that created this proctexture.

Implements iProcTexture.

virtual int csProcTexture::GetFlags | ( |  | ) | const`[protected, virtual]`

Return the flags which are used to register the texture.

Implements iTextureWrapper.

virtual iImage* csProcTexture::GetImageFile | ( |  | ) | `[protected, virtual]`

Get the iImage.

Implements iTextureWrapper.

virtual void csProcTexture::GetKeyColor | ( | int & | red,
|  | int & | green,
|  | int & | blue |
| ) |  |  | const`[protected, virtual]`

Query the transparent color.

Implements iTextureWrapper.

virtual const char* csProcTexture::GetTextureClass | ( |  | ) | `[protected, virtual]`

Get the "class" of this texture.

For more information, see iTextureHandle::GetTextureClass.

Implements iTextureWrapper.

virtual iTextureHandle* csProcTexture::GetTextureHandle | ( |  | ) | `[protected, virtual]`

Get the texture handle.

Implements iTextureWrapper.

iTextureWrapper* csProcTexture::GetTextureWrapper | ( |  | ) | `[inline]`

Get the texture corresponding with this procedural texture.

Definition at line 210 of file proctex.h.

virtual iTextureCallback* csProcTexture::GetUseCallback | ( |  | ) | const`[protected, virtual]`

Get the use callback.

If there are multiple use callbacks you can use this function to chain.

Implements iTextureWrapper.

iMaterialWrapper* csProcTexture::Initialize | ( | iObjectRegistry * | object_reg,
|  | iEngine * | engine,
|  | iTextureManager * | txtmgr,
|  | const char * | name |
| ) |  |  |

Initialize this procedural texture, create a material associated with it, properly register the texture and material and prepare them.

This function assumes that the texture manager has already been set up. It is a convenience function that offers less flexibility but is sufficient for most cases. The texture and material will get the name that is given by this routine.

virtual bool csProcTexture::Initialize | ( | iObjectRegistry * | object_reg | ) | `[virtual]`

Do everything needed to initialize this texture.

At this stage only will settings like the key color be used. The correct init sequence is:

- csProcTexture::Initialize()
- iTextureWrapper::Register()
- csProcTexture::PrepareAnim()

Alternatively you can use Initialize(engine,name) which does all this work for you.

virtual bool csProcTexture::IsVisitRequired | ( |  | ) | const`[protected, virtual]`

Return true if it is needed to call Visit().

Implements iTextureWrapper.

virtual bool csProcTexture::KeepImage | ( |  | ) | const`[protected, virtual]`

If this flag is true then the image will be kept even after calling Register.

If this flag is false then Register() will remove the image pointer from this texture wrapper. False by default.

Implements iTextureWrapper.

virtual bool csProcTexture::PrepareAnim | ( |  | ) | `[virtual]`

Prepare the animation for use.

Reimplemented in csProcAnimated.

virtual iObject* csProcTexture::QueryObject | ( |  | ) | `[protected, virtual]`

Get the iObject for this texture.

Implements iTextureWrapper.

virtual void csProcTexture::Register | ( | iTextureManager * | txtmng | ) | `[protected, virtual]`

Register the texture with the texture manager.

Implements iTextureWrapper.

virtual void csProcTexture::SetAlwaysAnimate | ( | bool | enable | ) | `[protected, virtual]`

Set the 'always animate' flag.

Implements iProcTexture.

virtual void csProcTexture::SetFlags | ( | int | flags | ) | `[protected, virtual]`

Set the flags which are used to register the texture.

Implements iTextureWrapper.

virtual void csProcTexture::SetImageFile | ( | iImage * | Image | ) | `[protected, virtual]`

Change the base iImage.

The changes will not be visible until the texture is registered again.

Implements iTextureWrapper.

virtual void csProcTexture::SetKeepImage | ( | bool | k | ) | `[protected, virtual]`

Set the keep image flag.

See KeepImage() function for explanation.

Implements iTextureWrapper.

void csProcTexture::SetKeyColor | ( | int | red,
|  | int | green,
|  | int | blue |
| ) |  |  | `[inline, virtual]`

Set the key color to use for this texture.

Implements iTextureWrapper.

Definition at line 185 of file proctex.h.

virtual void csProcTexture::SetTextureClass | ( | const char * | className | ) | `[protected, virtual]`

Set the "class" of this texture.

For more information, see iTextureHandle::SetTextureClass.

Implements iTextureWrapper.

virtual void csProcTexture::SetTextureHandle | ( | iTextureHandle * | tex | ) | `[protected, virtual]`

Change the texture handle.

The changes will immediatly be visible. This will also change the key color and registration flags to those of the new texture and the iImage to 0.

Implements iTextureWrapper.

virtual void csProcTexture::SetUseCallback | ( | iTextureCallback * | callback | ) | `[protected, virtual]`

Set a callback which is called just before the texture is used.

This is mainly useful for procedural textures which can then choose to update their image.

Implements iTextureWrapper.

virtual void csProcTexture::Visit | ( |  | ) | `[protected, virtual]`

Visit this texture.

This should be called by the engine right before using the texture. It is responsible for calling the use callback if there is one.

Implements iTextureWrapper.
