ConstraintHelper
public ConstraintHelper(java.lang.String blenderVersion,
BlenderContext blenderContext,
boolean fixUpAxis)
- Helper constructor. It's main task is to generate the affection functions. These functions are common to all
ConstraintHelper instances. Unfortunately this constructor might grow large. If it becomes too large - I shall
consider refactoring. The constructor parses the given blender version and stores the result. Some
functionalities may differ in different blender versions.
- Parameters:
blenderVersion
- the version read from the blend filefixUpAxis
- a variable that indicates if the Y asxis is the UP axis or not
loadConstraints
public void loadConstraints(Structure objectStructure,
BlenderContext blenderContext)
throws BlenderFileException
- This method reads constraints for for the given structure. The
constraints are loaded only once for object/bone.
- Parameters:
objectStructure
- the structure we read constraint's forblenderContext
- the blender context
- Throws:
BlenderFileException
createConstraint
protected Constraint createConstraint(Structure constraintStructure,
java.lang.Long ownerOMA,
Ipo influenceIpo,
BlenderContext blenderContext)
throws BlenderFileException
- This method creates the constraint instance.
- Parameters:
constraintStructure
- the constraint's structure (bConstraint clss in blender 2.49).ownerOMA
- the old memory address of the constraint's ownerinfluenceIpo
- the ipo curve of the influence factorblenderContext
- the blender context
- Throws:
BlenderFileException
- this exception is thrown when the blender file is somehow
corrupted
getConstraintClassName
protected java.lang.String getConstraintClassName(Structure constraintStructure,
BlenderContext blenderContext)
throws BlenderFileException
- Throws:
BlenderFileException
shouldBeLoaded
public boolean shouldBeLoaded(Structure structure,
BlenderContext blenderContext)
- Description copied from class:
AbstractBlenderHelper
- This method analyzes the given structure and the data contained within
blender context and decides if the feature should be loaded.
- Specified by:
shouldBeLoaded
in class AbstractBlenderHelper
- Parameters:
structure
- structure to be analyzedblenderContext
- the blender context
- Returns:
- true if the feature should be loaded and false otherwise
