Member Function Documentation

virtual bool iSpriteCal3DState::AddAnimCycle ( int  idx,
float  weight,
float  delay 
) [pure virtual]

Uses the specified index directly to add the anim cycle.

virtual bool iSpriteCal3DState::AddAnimCycle ( const char *  name,
float  weight,
float  delay 
) [pure virtual]

This adds the specified animation to the ones already being blended by cal3d.

The weight value is dependent on other weights used, and is only relative. The delay is the period in seconds over which the blended weight will be interpolated from 0 to "weight" value. A cal3d anim cycle, by definition, is a looping animation (see SetAnimAction for non-looping anims).

virtual bool iSpriteCal3DState::AttachCoreMesh ( int  mesh_id,
iMaterialWrapper iMatWrap = 0 
) [pure virtual]

This attaches a mesh with the specified calCoreModel id (as returned by iSpriteCal3DFactoryState::FindMeshName() to the instance of the model.

It is expected this function is only called by the mesh object itself under normal circumstances. Callers should normally refer to meshes by name to prevent behavior changes when xml order is updated. iMatWrap is the iMaterialWrapper to be used in rendering.

virtual bool iSpriteCal3DState::AttachCoreMesh ( const char *  meshname  )  [pure virtual]

This attaches a mesh with the specified name (from xml) to the instance of the model.

virtual bool iSpriteCal3DState::BlendMorphTarget ( int  morph_animation_id,
float  weight,
float  delay 
) [pure virtual]

Blends the morph target.

Parameters:
morph_animation_id The id of the morph animation we want to blend.
weight The weight of the morph target.
delay The delay untill the full weight is reached.
Returns:
False if something went wrong.

virtual void iSpriteCal3DState::ClearAllAnims (  )  [pure virtual]

This resets all currently blended animations and stops the sprite.

virtual bool iSpriteCal3DState::ClearAnimCycle ( const char *  name,
float  delay 
) [pure virtual]

This removes the named animation from the current blend set over the period of time specifed by "delay" parm in seconds.

Returns true if the named animation was found; else false.

virtual bool iSpriteCal3DState::ClearAnimCycle ( int  idx,
float  delay 
) [pure virtual]

This removes the animation at index `idx' from the current blend set over the period of time specifed by "delay" parm in seconds.

virtual bool iSpriteCal3DState::ClearMorphTarget ( int  morph_animation_id,
float  delay 
) [pure virtual]

Clears the morph target.

Parameters:
morph_animation_id The id of the morph animation we want to clear.
delay The delay untill the morph target is cleared.
Returns:
False if something went wrong.

virtual bool iSpriteCal3DState::DetachCoreMesh ( int  mesh_id  )  [pure virtual]

This detaches a mesh with the specified calCoreModel id to the instance of the model.

It is expected this function is only called by the mesh object itself under normal circumstances. Callers should normally refer to meshes by name to prevent behavior changes when xml order is updated.

virtual bool iSpriteCal3DState::DetachCoreMesh ( const char *  meshname  )  [pure virtual]

This detaches a mesh with the specified name (from xml) to the instance of the model.

Remarks:
Note that changes made to the mesh's shader variable context will get lost.

virtual int iSpriteCal3DState::FindAnim ( const char *  name  )  [pure virtual]

Find the index of the named animation. Returns -1 if not found.

virtual iSpriteCal3DSocket* iSpriteCal3DState::FindSocket ( const char *  name  )  const [pure virtual]

find a named socket into the sprite.

virtual iSpriteCal3DSocket* iSpriteCal3DState::FindSocket ( iMeshWrapper mesh  )  const [pure virtual]

find a socked based on the sprite attached to it.

virtual size_t iSpriteCal3DState::GetActiveAnimCount (  )  [pure virtual]

Returns the count of currently playing animation cycles.

This should be used to allocate the buffer required by GetActiveAnims below.

virtual bool iSpriteCal3DState::GetActiveAnims ( csSpriteCal3DActiveAnim buffer,
size_t  max_length 
) [pure virtual]

Fills the supplied buffer with the information to reconstruct the exact animation mix currently playing in the model.

It does NOT include any non-repeating actions. Those must be handled separately, due to the timing issues.

Parameters:
buffer Buffer receiving information about active animations.
max_length Maximum number of entries that fit into buffer.
Returns:
Whether the buffer was successfully filled.

virtual float iSpriteCal3DState::GetAnimationDuration (  )  [pure virtual]

Return whole animation duration.

virtual float iSpriteCal3DState::GetAnimationTime (  )  [pure virtual]

Return current animation time.

virtual int iSpriteCal3DState::GetAnimCount (  )  [pure virtual]

Returns the number of animations currently loaded for the core model.

virtual const char* iSpriteCal3DState::GetAnimName ( int  idx  )  [pure virtual]

Returns the name, from the xml file, of the indexed anim, or 0 if out of bounds.

virtual int iSpriteCal3DState::GetAnimType ( int  idx  )  [pure virtual]

Returns the type from the enum above, as specified in the XML.

virtual CalModel* iSpriteCal3DState::GetCal3DModel (  )  [pure virtual]

Gives access to the internal Cal3d Model instance.

virtual iShaderVariableContext* iSpriteCal3DState::GetCoreMeshShaderVarContext ( const char *  meshName  )  [pure virtual]

Return the current time factor of the model.

virtual void iSpriteCal3DState::SetActiveAnims ( const csSpriteCal3DActiveAnim buffer,
size_t  anim_count 
) [pure virtual]

Uses the supplied buffer (created by GetActiveAnims) to recreate an exact mix of animation cycles and weights.

virtual bool iSpriteCal3DState::SetAnimAction ( int  idx,
float  delayIn,
float  delayOut 
) [pure virtual]

This adds a non-looping animation to the blend set for the cal3d Mixer.

This animation will play one time overlaid on top of the other currently active animations. delayIn and delayOut allow you to fade in and fade out the action for smoothness of response.

virtual bool iSpriteCal3DState::SetAnimAction ( const char *  name,
float  delayIn,
float  delayOut 
) [pure virtual]

This adds a non-looping animation to the blend set for the cal3d Mixer.

This animation will play one time overlaid on top of the other currently active animations. delayIn and delayOut allow you to fade in and fade out the action for smoothness of response.

virtual void iSpriteCal3DState::SetAnimationTime ( float  animationTime  )  [pure virtual]

Set current animation time.

virtual bool iSpriteCal3DState::SetAnimCycle ( int  idx,
float  weight 
) [pure virtual]

This clears the active anims for this sprite and sets it to use only the specified anim, where the anim is specified by index.

virtual bool iSpriteCal3DState::SetAnimCycle ( const char *  name,
float  weight 
) [pure virtual]

This clears the active anims for this sprite and sets it to use only the specified anim, where the anim is specified by name.

virtual void iSpriteCal3DState::SetAnimTimeUpdateHandler ( iAnimTimeUpdateHandler  )  [pure virtual]

This gives you ability to update the internal Cal3d model directly rather than relying upon the default behavior which merely invokes CalModel::update().

You may need to do this, for example, when you want to move Cal3d skeleton from your own code (to implement rag-doll physics, for instance).

virtual void iSpriteCal3DState::SetDefaultIdleAnim ( const char *  name  )  [pure virtual]

This function sets the name to use when SetVelocity(0) is called.

virtual void iSpriteCal3DState::SetLOD ( float  lod  )  [pure virtual]

This function sets the Level of Detail used by the sprite.

This is used to reduce the polygon count and simplify the scene for the renderer.

virtual bool iSpriteCal3DState::SetMaterial ( const char *  mesh_name,
iMaterialWrapper mat 
) [pure virtual]

Change the material on a named submesh. Returns true if successful.

virtual void iSpriteCal3DState::SetTimeFactor ( float  timeFactor  )  [pure virtual]

Set the animation time adjustment factor. 1=normal speed.

virtual void iSpriteCal3DState::SetUserData ( void *  data  )  [pure virtual]

Set user data in the model, for access from the callback later, mostly.

virtual bool iSpriteCal3DState::SetVelocity ( float  vel,
csRandomGen rng = 0 
) [pure virtual]

This function searches all actions specified as type TRAVEL for actions with a base velocity matching "vel", and blends them into a travel action.

If no animation is found with a base animation that exactly matches "vel" It selects animations with an appropriate velocity range and blends them to create the travel animation. The calling program is still responsible for actually moving the sprite.
