Constructor Detail

AnimatableMotionPointValue

protected AnimatableMotionPointValue(AnimationTarget target)
Creates a new, uninitialized AnimatableMotionPointValue.


AnimatableMotionPointValue

public AnimatableMotionPointValue(AnimationTarget target,
                                  float x,
                                  float y,
                                  float angle)
Creates a new AnimatableMotionPointValue with one x.

Method Detail

interpolate

public AnimatableValue interpolate(AnimatableValue result,
                                   AnimatableValue to,
                                   float interpolation,
                                   AnimatableValue accumulation,
                                   int multiplier)
Performs interpolation to the given value.

Specified by:
interpolate in class AnimatableValue
Parameters:
result - the object in which to store the result of the interpolation, or null if a new object should be created
to - the value this value should be interpolated towards, or null if no actual interpolation should be performed
interpolation - the interpolation distance, 0 <= interpolation <= 1
accumulation - an accumulation to add to the interpolated value
multiplier - an amount the accumulation values should be multiplied by before being added to the interpolated value

getX

public float getX()
Returns the x coordinate.


getY

public float getY()
Returns the y coordinate.


getAngle

public float getAngle()
Returns the rotation angle.


canPace

public boolean canPace()
Returns whether two values of this type can have their distance computed, as needed by paced animation.

Specified by:
canPace in class AnimatableValue

distanceTo

public float distanceTo(AnimatableValue other)
Returns the absolute distance between this value and the specified other value.

Specified by:
distanceTo in class AnimatableValue

getZeroValue

public AnimatableValue getZeroValue()
Returns a zero value of this AnimatableValue's type.

Specified by:
getZeroValue in class AnimatableValue

toStringRep

public String toStringRep()
Returns a string representation of this object.

Overrides:
toStringRep in class AnimatableValue
