Collision Detection In Blender's Rigid Body Physics | An Advanced Tutorial Based On Python Script

In this Blender tutorial, we have discussed how to detect a collision in Rigid Body Physics or during any animation in Blender. We have used a Python script to detect this collision and the script is free for everyone. The download link is given below. You can make use of this script for various scenarios, one such scenario is discussed in this tutorial where we are changing the material of an object based on its collision with another object. Please watch the video for the complete tutorial. If you have any question on this tutorial, please leave your comment below.

Never used Blender before but I’m trying to do 3 words landing in each other with a slight bounce for an intro. I’m guessing the rigid body dynamics would work for this? People are suggesting cinema 4d and Houdini also.

Just started to use the platform and got an error trying to use the node:

Python: Traceback (most recent call last):
File "\Text", line 204, in <module>
AttributeError: 'NoneType' object has no attribute 'node_group'

Thanks for sharing, it gave me a whole new experience

[MrBeStack]

i'm using v4.0.2 and when i search for the Greater Than node nothing populates. i have to add the math node and manually switch it to greater than from add. I'm trying to add this to the music notes tutorial, and I can not get the Cubes to change colors using the code provided.

[Alex-tnkt]

Hello ! Thank you for all this knowledge ! I am new to Blender and you are very helpfull :)

Unfortunately I have a problem with this collision detection script, I am using Blender 4.1
I tried to run this script to use with your musical marble animation (really nice tutorial too) but it gives me some errors
I put the marble and all the notes in a collection and I select the marble, then I run the script and it says :

Python: Traceback (most recent call last):
File "C:\Users\***\\Marble_music\untitled.blend\Text.001", line 195, in <module>
File "C:\Users\***\Marble_music\untitled.blend\Text.001", line 59, in create_geometry_node_group
IndexError: bpy_prop_collection[index]: index 3 out of range, size 3

Maybe you can help me with that

Thank you and keep making tutorials its a pleasure to follow them ;)

[MacTavish]

Sorry Bro, I don't understand the tutorial. because this tutorial is for lots of balls falling, se Meanwhile, I want to change the color of several Single Musical Notes when one ball touches them alternately. Apart from that, I'm not very good at English which means I don't really understand what you're saying. Even though YouTube has a subtitle feature, it doesn't fully understand me.🙏

Will this allow circle packing? Sphere packing?

[MarbleMusicMistery]

I get error when try to use this Python: Traceback (most recent call last):
File "\Text", line 195, in <module>
File "\Text", line 124, in create_geometry_node_group
TypeError: bpy_struct: item.attr = val: expected a string type, not bool.

Can you help maybe?

[degoblack]

I have a question, how do i make y particles have their own colliders?

[arya_rudra]

as AI is entering in every field what is our future in animation

[gohai-oy]

Read prefs:
Read blend: "G:\Blender\music ball\music ball_04_rigid.blend"

Error in PyDriver: expression failed: Frame

thank you very much!it is very good ! i don't know the error?

"Hi, how can I change the Plane instead of the Sphere color?"

[mustaphamaxlogo]

thank you, and please the password for the zip file

[darrennew]

I think you forgot to actually include the link to the script.
