If collision between two object more than 50% destroy it?

i wanna ask how to make the script
If collision between two object more than 50% destroy it?
i really out of idea for that

Example like this
1386476--71079--$Untitled-1.png

50% of what?

maybe instead you should check the velocity of how fast the objects were going when they actually do collide. Just a suggestion.

Take a look at collision.relativeVelocity.magnitude

(eg)

if (collision.relativeVelocity.magnitude > 2) {
// Cut my grass
}

I mean 2 object collision and if the collision percentage less than 50% will destroy,
you know what i mean?
see the example image below
1386476--71079--$Untitled-1.png

Unfortunately I don’t know what you mean. What is the thing you want to measure a percentage of?

measure how many touch collision between 2 object, you know what i mean?

He means if the two colliding objects don’t just clip each other. Instead, at least 50% of one side is covered up after the collision.

This might help out: Unity - Scripting API: Collision.contacts

Thanks but i don’t understand what it mean for
