Tips on animating objects

Anonymous — Mon, 21 May 2012 00:41:07 GMT

I just saw a discussion on linkedin about how to animate objects in ArchiCAD. This is actually surprisingly easy to achieve with basically any existing parameter - a fact most user don't realize.

Eg say you have a car object that you want to move 1m metre per animation frame, all you have to do is add the following line to the top of the object's 3D script:
ADDx GLOB_FRAME_NR * 1 !1 moves it 1m per frame.

Anyone got any other tips

Can you make the wheels spin?

haha sure can! just multiply their angle parameter e.g. wheelAngle like this:
wheelAngle * (GLOB_FRAME_NR * 15) this will move them 15 degrees per frame.

Now if you were really clever you could use a calc to work out how much your wheels should turn, based on how fast the car is moving each frame 😉

And if you get the calcs wrong and the wheels spin too fast you'll get plumes of smoke and black lines all over your plan.

We had a discussion on this (animate objects) a few weeks ago, on ArchiRADAR, started on an old tutorial.
The aim, in this case, was to simulate the swing movement of a boat, while moving ahead.
The solution proposed is enough for a simple animation, although the waving movement is a crude zig-zag, not something smooth like sinusoid.

The whole thing is in Italian, but you can find something interesting.

Very interesting...

Sounds good. We got a smoother motion on a couple objects by multiplying the frame number * SIN or COS
