Colliders 2D

In Box2D there are two types of colliders: solid and sensor.

• Solid -> default collider which provides collision and other bodies with solid colliders cannot pass through it. IsSensor should be false.
• Sensor -> collider which doesn't provide collision and other colliders pass through (overlap) it. IsSensor should be true.

In the image below you can see how the CircleCollider2D on blue NPC(on right) and CapsuleCollider2D on Player(left) have IsSensor=true so they overlap with other shapes, unlike the BoxCollider2D on the Player and small CapsuleCollider2D on the NPC which are IsSensor=false and they prevent them from falling from the horizontal rectangle which is BoxCollider2D with IsSensor=false.

You can also set more precisely collider behaviour using Collision Matrix from Layer System
soon example will be added
