Hinge constraint problem in breaking doors effect

[Juraj]

Hello,

I'm learning constraints and I've decided to create simulation of breaking doors. However I've run into problems I cannot solve.

You can see them in this video:

I also attached project file so that you can look at it.

Is my approach correct?

 

Thanks

Now your file is totaly messed up but it works)

Great!

Big thanks , I couldn't figure out the correct approach.

It's best to learn from project file.

Thank you,

I can see that you are using attribwrangle for creating constraints which must be faster than foreach. But with my skills I am ok with foreach .

Your file works great, but when I try to add cone-twist constraints to add some realism, simulation goes wrong. Doors hinges seems to lean a bit. And wood pieces doesn't seem to stop moving once they are on ground. This problem was present also in your file.

I tried modifying Collision padding which helped a bit but not much.

rearranged your file again. I've found that glue constraints don't work good in company with all hard constraint types(i e pin, cone-twist etc). Also instead of testing angle attrib to blast constraints I prefer torque since it looks kind of better.
