au3Irr2 Function Reference

_IrrAddSplineAnimator

---

Animator moving its parent node along a spline curve.

#Include <au3Irrlicht2.au3>
_IrrAddSplineAnimator($h_Node, $tVectorStruct, $i_Start, $f_Speed, $f_Tightness)

 

Parameters

$h_Node	Handle of a scene Node.
$tVectorStruct	Struct array with 3D-points defining the spline curve. Use __CreateVectStruct and __SetVectStruct to build the required struct.
$i_Start	Time in milliseconds that must pass before the animation starts.
$f_Speed	Defines the rate the node moves along the spline curve.
$f_Tightness	Specifies how tightly the curve is tied to the points. Value between 0 (angular) and 1 (very loose).

 

Return Value

Success: Handle of the created animator.
Failure: False and sets @error:
    1 - error from .dll call
    2 - $tVectorStruct is not a dllstruct

 

Remarks

This is one of the more difficult to set up of the animators but is very natural looking and powerful.
A spline is a curved line that passes through or close to a list of co-ordinates, creating a smooth flight.
This animator needs a list of coordinates stored in a struct array for the X, Y and Z locations of all the points.
A good way to get coordinates for this struct is to load in the camera position example and move your camera to a point and write down its coordinates.
