3D: Controlling action
on mSlide(me)
vElapsed = the milliseconds - pThrowTime
if vElapsed > pTimeToStop then
vElapsed = pTimeToStop
(the actorList).deleteOne(me)
-- This will be the last time the puck moves
end if
vDistance = (pSpeed + (pAcceleration*vElapsed)/2) * vElapsed
vWorldPosition = pThrowSpot + pDirection * vDistance
pPuck.worldPosition = vWorldPosition
end mSlide
The puck stops
Notice how the mSlide() handler checks whether the puck moment when the puck stops has passed. If it does not do
this, the puck will come to a stop, and then start to accelerate in the opposite direction, as if friction behaved like an
elastic band.
Interpolation
The interpolate() and interpolateTo() methods allow you to calculate a transform that is partway between one
transform and another. To visualize what this means, download and launch the movie Interpolation.dir.
Dragging the slider will move the blue half-cone from the between the two other half-cones
Using interpolate()
The syntax for the interpolate method is:
outputTransform = transform1.interpolate(transform2, aPercentage)
The value of aPercentage must be between 0.0 and 100.0. If you use a value outside this range, a script error occurs.
The output is a transform, the scale of which will be vector(1.0, 1.0, 1.0), regardless of the scales of the input
transforms. The position and rotation properties of the output transform will be a weighted average of the
position and rotation of the two other transforms.
If aPercentage is 0.0, then the output is a transform whose position and rotatation are identical to that of
transform1. If aPercentage is 100.0, then the output is a transform whose position and rotatation are identical
to that of transform2.
