# IFX with colliders

When an IFX has a collider enabled, users can't move through it, but may be able to teleport onto it. Some of the IFX with colliders have a transparent version. You can use these to add physical barriers or teleport targets to otherwise non-physical objects.

## Adding IFX with colliders to an experience

1. If the timeline view isn't active in the editor panel, select the timeline icon (<img src="/files/27TqEemJlgqsBCre7AcG" alt="" data-size="line">).
2. From the panel on the left-hand side, select <img src="/files/IoOEPZLPOKWyDb5ynAZd" alt="" data-size="line"> **IFX**.
3. From the library of IFX, select an IFX that includes `Collider` somewhere in its title.
4. Place the IFX in the environment. For more information about the controls that are available when you add an IFX, see [Adding IFX](/engage/advanced-features/using-ifx/adding-ifx.md).
5. Access the effect options for the IFX, and then select the **Enable Collider** check box. For more information, see [#collider-effect-options](#collider-effect-options "mention").

{% hint style="info" %}
If an IFX has the text `Invisible` in its title, it will be visible only when you use the move or gizmo controls in the Experience Editor. If an IFX has `Teleport` in its title, it creates a surface that people can teleport onto. Only IFX with `Teleport` in their title create valid teleport surfaces.
{% endhint %}

## Collider effect options

For instructions on how to access effect options, see [Effect options](/engage/experience-editor/working-with-objects/effect-options.md). For IFX with colliders, the only additional option is to enable colliders. You must enable this option for the IFX to detect collisions.
