Attribute Error

I’m trying to use the fluid collision system
i followed what the manual says but i’m having an error and i can’t figure out why .

In the manual it says that we have to ensure to call at least once the


for each frame but when i do that , i get the following message :

Attribute Error : ShowBase instance has no attribute 'resetPrevTransform' 

I hope someone know how to deal with that


Hmm. As the manual page says too, this is automatically done and you should only use it when you have scene graphs separate from render.

right but it seams that the function do not exist …
and i see no difference from before :slight_smile:

It only happens if you have a very rapidly moving object with a low FPS through a thin object.

ok thanks you
