I making a difficult 2d platform that's why i want to make really cool death effect where player break in parts with a lot of blood.
You need to provide a bit more information, if you want good answers.
But is sounds like you could just create a rigidbody for every limb.
Give them an impulse from the direction, where the death comes from, add a little bit of random and it should be good.
Hi, I'm not in any way experienced with the specifics (or godot at all), but perhaps these tutorials might be of some help.
