GDL object moving

Anonymous — Tue, 14 Sep 2010 11:23:37 GMT

We are doing a 4D project with the plug-in in ArchiCAD 14. I would like my cranes (3ds-converted objects) to move as the simulation runs with one or more cameraes-

It must be a ROTz..... something like this with a 4x4x4 block:

BLOCK 4,4,4

ADDx 2
ADDy 2

ROTz (N_+1)/(P_+1)

del 1

HOWEVER, it does not work - what went wrong?

Thanks.

Did you tick the box for rebuild model for each frame in the Save fly through settings?

Oh yes, but still there is no movement...Is my script correct? Tried to look something up in the COOKBOOK without any luck although there a movements in many of the samples:-)

I think it may helps.

try this:

_ang=360
ROTz (GLOB_FRAME_NR+1) * _ang/(GLOB_LAST_FRAME+1)

The BLOCK command must be after the ROY but before the DEL.

There is also a broblem with your maths.

ROTz (N_+1)/(P_+1) will only rotate by a minute amount each time

Just use ROTz N_ to rotate one degree each frame.

YEP, it is working now - my block is moving fine with:

ROTz N_

BLOCK 4,4,4

BUT not around its own axis in the middle of the object....How to?

You will need to ADD by the negative value of half the block size then place the block then DEL to put the cursor back to the original position.

ADD -2, -2, 0
BLOCK 4,4,4
DEL 1
