Bird back to start

Anton_S

Very nice birdy, faust07.

Here is the code to make the birdy loop on the desired curve.


setLinearDamping(5.0)
onstart {
  curve_verts = $curPhysicsSimulation.findCurve("path01")
  @curve_length = $curPhysicsSimulation.getCurveLength(curve_verts)
}
ontick{
   lookAt(evalCurveAbs("path01", (frame * 8) % @curve_length + 180))
   dir = position.vector_to(evalCurveAbs("path01", (frame * 8) % @curve_length))
   dir.length = dir.length / 12.0
   push(dir.to_a)
}

Of course, the main curve isn't quite "loopable", so the transitioning from the last point to the starting point won't be quite realistic until the curve is modified to be "loopable".

It's a code for SketchyPhysics or MsPhysics ?

Does it possible also in MSPhysics ?

Anton_S

The code is for SketchyPhysics (as the birdy was made for SP). Copy and paste it into the body of the bird into the script field.

Yes, everything done in SketchyPhysics can be tweaked to work in MSPhysics. (The code would look different however as the scripting functions differ in SketchyPhysics and MSPhysics.)

Thank you very much, Anton! Works like a charme:
And the script supplement looks so easy. Nevertheless, I still need some time to understand it.
Endless flying birds in the sky are no longer a problem...

this whole "SP-thing" is a miracle to me and with big eyes I am so amazed like a child
It's great to see the bird´s flight, it´s movements just like the perfect camera tracking.
When I myself am glad that any cube falls right down onto the ground, the here shown
SP-level is enchanting.

just great!

Well done @faust07

Nice and smooth and the movement of the wings looks very realistic.

Thanks again for the kind words guys. Here a little more bird action ... Everything is normal SketchUp output. The possibilities for designing camera movements with SketchyPhysics are unlimited. Thats great! The bird is flying in Antons loop. The camera is controlled by the SUp scenes.
Hi Chri. Telepathy ... Unfortunately, I can only animate one bird. To copy Physics objects is very time consuming. But nothing is perfect...

Hi faust

Incredible Job !

Before I saw this, I did not think we could do this , with SKETCHUP.

Thanks for sharing

Benchmark for Sketchy Physics...

2 birds and a bit emitter fun

Haha. Talk about rampant development!
