Interaction Interface

The actor you want this component to interact with has to implement the BPI_Interaction. You will get these following functions with the interface. Check out the W_Console for an example.

On Hover

It should have On Interaction Component Hover setup to work properly. You will need to create Ref and RefsWaiting variables in your actor. You can further customize it with your logic.

On Unhover

It should have On Interaction Component Unhover setup to work properly. You will need to create Ref and RefsWaiting variables in your actor. You can further customize it with your logic.

On Interaction

This function doesnt need a setup but it needs a response. This response is used for On Interaction Successful.

Functions

Add to Ignore and Set Interaction Active

Use these functions to change Interaction Component's settings on runtime.

Event Dispatchers
