Collision
Collided: Triggers when the input object collides with another object, including the floor.
2nd Object: Outputs the object that the input object collided with. It'll output "None" if collided with the floor.
Impulse: Outputs the impact force of the collision (how hard did they collide). Specifically, impulse is a change of momentum of an object.
Normal: Outputs the direction of the impact from the object that the input object collided with.
Examples
The script below causes you to win if the two physics boxes collide with each other.
Because the ground counts as "None", the script below causes you to lose if the sphere touches the ground.
Triggers a sound effect only if the impulse is big enough.
