+### 📚 Registering a New Entity Class
 
 To implement a custom entity, the first thing you need to do is register a new entity class using the `CE_RegisterClass` native function. This can be done in the `plugin_precache` function, allowing you to place your entities directly on the map using the registered class as the `classname`.

 In this example, the `CEPreset_Item` preset class is used to implement the item. It inherits logic for items such as pickup methods.

 Natives like `CE_SetMemberString` and `CE_SetMemberVec` are used to set members/properties for the entity instance. Constants such as `CE_MEMBER_*` are used to specify the property names that will set the model each time the entity is spawned or its variables are reset. For example, `CE_MEMBER_MODEL` sets `pev->model` of the entity every respawn. Similarly, `CE_MEMBER_MINS` and `CE_MEMBER_MAXS` specify the entity's bounding box.

 You may have noticed the constant `m_iType`, which is a string constant used for the custom member we work with using `CE_GetMember` and `CE_SetMember` natives. We also use `CE_RegisterClassKeyMemberBinding` to bind this member to the entity key `type`, allowing us to change the key type by setting the `type` key-value on the map.
