# Collide with AABox
|
|
|
|
Menu Path : **Collision > Collide with AABox**
|
|
|
|
The **Collide with AABox** Block defines an axis-aligned box volume that particles collide with.

|
## Block compatibility
|
|
|
|
This Block is compatible with the following Contexts:

|
## Block settings
|
|
|
|
| **Setting** | **Type** | **Description** |
|
|
| ----------------- | -------- | ------------------------------------------------------------ |
|
|
| **Mode** | Enum | The collision shape mode. The options are:<br/>• **Solid**: Particles cannot enter the collider.<br/>• **Inverted**: Particles cannot leave the collider. The collider becomes a volume that the particles cannot exit. |
|
|
| **Radius Mode** | Enum | The mode that determines the collision radius of each particle. The options are:<br/>• **None**: Particles have a radius of zero.<br/>• **From Size**: Particles inherit their radius from their individual sizes.<br/>• **Custom**: Allows you to set the radius of the particles to a specific value. |
|
|
| **Rough Surface** | Bool | Toggles whether or not the collider simulates a rough surface. When enabled, Unity adds randomness to the direction in which particles bounce back to simulate collision with a rough surface. |

## Block properties
|
|
|
|
| **Input** | **Type** | **Description** |
|
|
| ----------------- | ---------------------- | ------------------------------------------------------------ |
|
|
| **Box** | [AABox](Type-AABox.md) | The axis-aligned box that specifies the center position and size of the collision volume. |
|
|
| **Bounce** | Float | The amount of bounce to apply to particles after a collision. A value of 0 means the particles do not bounce. A value of 1 means particles bounce away with the same speed they impacted with. |
|
|
| **Friction** | Float | The speed that particles lose during collision. The minimum value is 0. |
|
|
| **Lifetime Loss** | Float | The proportion of life a particle loses after collision. |
|
|
| **Roughness** | Float | The amount to randomly adjust the direction of a particle after it collides with the surface.<br/>This property only appears when you enable **Rough Surface**. |
|
|
| **Radius** | Float | The radius of the particle this Block uses for collision detection.<br/>This property only appears when **Radius Mode** is set to **Custom**. |
