Hello,
I have a CSV file with force data and I want to be able to draw a circle on the ground that will be "at the foot" of an object and I want the circle to grow and decrease according to the value of the force. Is it possible to do that ?
I'm using the python API.
Thanks in advance

Yes, with sim.addDrawingObject and sim.addDrawingObjectItem

Every time I try to put this function in my code I get this error :
AttributeError: module 'sim' has no attribute 'addDrawingObject'

It is highly recommended to use the
ZeroMQ remote API, since it is much easier and flexible. Additionally, you'll have access to many more API functions, than with the legacy remote API.

For what you want to draw, you can use
sim.drawing_discpts (to draw discs) combined with
sim.drawing_itemsizes which takes one additional number (in sim.addDrawingObjectItem) to specify the item size:
Code: Select all
dwo=sim.addDrawingObject(sim.drawing_discpts|sim.drawing_itemsizes,0.1,0,-1,1000,{1,0,0})
-- pos: quat: size:
sim.addDrawingObjectItem(dwo,{0.5, 0,0, 0,0,0,1, 0.2})
sim.addDrawingObjectItem(dwo,{ 0,0.5,0, 0,0,0,1, 0.1})
sim.addDrawingObjectItem(dwo,{0.5,0.5,0, 0,0,0,1, 0.05})

Thank you for your help.
I have another question.
With this API can I still use my previous codes made with the other API or do I have to readapt my code?
Thank you in advance for your answer

The ZMQ Remote API is a 1:1 equivalent of the (lua) Regular API.
If you used the Regular API (e.g. in model scripts), it works in the same way.
If you used the legacy Remote API you might need to make minor adjustments.

Yes (by passing the foot handle to the parentObjectHandle param).
