Fun to see you are learning Tundra scripting fast. And to answer your
question yes this is one way of doing movement if we are talking about pos,
rot, scale. You can make it a bit cleaner by just using the transform to
assing new values and assign it back to the placeable like so:
function updates()
{
var t = me.placeable.transform;
if (tarpos.x != t.pos.x)
t.pos.x = tarpos.x > t.pos.x ? t.pos.x + moveSpeed : t.pos.x -
moveSpeed;
if (tarpos.y != t.pos.y)
t.pos.y = tarpos.y > t.pos.y ? t.pos.y + moveSpeed : t.pos.y -
moveSpeed;
if (tarpos.z != t.pos.z)
t.pos.z = tarpos.z > t.pos.z ? t.pos.z + moveSpeed : t.pos.z -
moveSpeed;
<same for rot, just use t.rot>
<whatever else logic you need>
// Assign back to the full trasnform attribute, no need for new
Transform(..)
me.placeable.transform = t;
}
Other option is to use the math library lerp and slerp functions, I have
made some camera transition movement animations with them. float3 and Quat
for example has them http://clb.demon.fi/MathGeoLib/docs/float3_Lerp.php For
the t you can use eg. QTimeLine
http://doc.trolltech.com/4.7/qtimeline.html with
setting duration and range from 0.0 to 1.0 and connecting to the proper
signal.
For animations you need to have a EC_Mesh with a .mesh ref and a .skeleton
ref set. Then you need EC_AnimationController component in the same entity.
This will "snoop" the available animations from the .skeleton file in the
EC_Mesh and you have various playback and stop functions for the
animations, eg. me.animationcontroller.EnableExclusiveAnimation("walk",
true); See doxygen for
more<http://realxtend.org/doxygen/class_e_c___animation_controller.html>
.
Hope that helps.
