# Prevent gun clipping through walls
The JU TPS has a system that prevents gun clipping through walls, and it works very simply
## Prevent Gun Clipping Script
This script uses a additional **Wielding Position ID** from the [**Item Aim Rotation Center**](/ju-tps-documentation/game-development/how-to-use-inventory-and-add-items/how-to-align-weapon-rotation.md#item-aim-rotation-center-align) to adjust the weapon's position to avoid clipping through walls. This script must be added to each weapon individually.
| Parameters | Description |
| ---------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| To Up Direction Wielding ID | Basically it is the ID in the[ **Item Aim Rotation** ](/ju-tps-documentation/game-development/how-to-use-inventory-and-add-items/how-to-align-weapon-rotation.md#item-aim-rotation-center-align)Center that prevents the gun clipping through walls |
| Ray Distance | Distance from [**Item Aim Rotation Center**](/ju-tps-documentation/game-development/how-to-use-inventory-and-add-items/how-to-align-weapon-rotation.md#item-aim-rotation-center-align) to the tip of the gun barrel |
| Block Gun Fire On Prevent Clipping | Makes it impossible for the character to shoot while preventing the weapon from clipping through walls |
| Walls Layers | Layers that the Raycast will detect walls |
| On Prevent | Unity Event that is called when a wall is detected |
| On Stop Prevent | Unity Event that is called when a wall stops being detected |
## Creating a Prevent Gun Clipping Wielding Position Reference
The image below shows what a **Wielding Position Reference** should look like to prevent gun clipping.
You can create adjustments that prevent gun clipping individually per weapon, just create new **Wielding Position References** and adjust the position, that should be close to the body and pointing in a direction other than forward, and then write the **Switch ID** in the first parameter of the **Prevent Gun Clipping Script**
