# Collision

**Collision** consists of a group of triggers that are activated when the interaction between the objects occurs. From a dropdown list you can choose from 4 options: *No Collision, Collision Started, Collision Continue, Collision Ended*. All collision triggers have their own color Icons.

Note: not all objects created in the game appear in the dropdown list for collision triggers. Only objects with Physics can collide.

No Collision is a trigger that keeps the animation playback when the objects are not in the process of interaction.

#### Collision Started

Collision Started is a trigger that is initiated when objects have just collided. This trigger captures the moment of collision itself.

#### Collision Continue

Collision Continue helps to keep the animation playback while the objects are in the process of interaction.

#### Collision Ended

Collision Ended is a trigger which captures the moment when the collision between the objects is over and launches the animation after that.
