# Interface ksIQueryFilter

Namespace: [KS.Reactor](/reactor/api-reference/ks.reactor.md)\
Assembly: KSCommon.dll

Interface for query filters that filter colliders from scene queries.

```csharp
public interface ksIQueryFilter
```

## Methods

### Filter(ksICollider, ksICollider, ksQueryResultTypes, ksBaseQueryParams) <a href="#ks_reactor_ksiqueryfilter_filter_ks_reactor_ksicollider_ks_reactor_ksicollider_ks_reactor_ksqueryres" id="ks_reactor_ksiqueryfilter_filter_ks_reactor_ksicollider_ks_reactor_ksicollider_ks_reactor_ksqueryres"></a>

Determines if a potential collider hit should be included in query results and whether it is a blocking or touching hit.

```csharp
ksQueryHitTypes Filter(ksICollider queryCollider, ksICollider hitCollider, ksQueryResultTypes resultType, ksBaseQueryParams args)
```

#### Parameters

`queryCollider` [ksICollider](/reactor/api-reference/ks.reactor/ks.reactor.ksicollider.md)

The collider used in the query. Null for shape queries.

`hitCollider` [ksICollider](/reactor/api-reference/ks.reactor/ks.reactor.ksicollider.md)

The collider being evaluated for a hit.

`resultType` [ksQueryResultTypes](/reactor/api-reference/ks.reactor/ks.reactor.ksqueryresulttypes.md)

What kind of results the query returns

`args` [ksBaseQueryParams](/reactor/api-reference/ks.reactor/ks.reactor.ksbasequeryparams.md)

Query parameters

#### Returns

[ksQueryHitTypes](/reactor/api-reference/ks.reactor/ks.reactor.ksqueryhittypes.md)

Hit type
