Yesterday I developed a blueprint which highlights the actor that the player is looking at (using traces and blendables). The problem is that all the actors are highlighted (when the player looks at them). I want to highlight only the “Selectable” actors.
If i were developing my game in an Object Oriented programming language, I would simply create a “Selectable” Interface/Trait/Mixin and extend it in all the objects that I want to be selectable. I want to have the same behaviour using Blueprints, but I dont know how to extend the actors. For example I want to add a Chair (the sample one) to my level and assign that behaviour. Is there a way to create my own Objects which extend from another (for example, a Chair) and have a custom behaviour (Selectable)?
Thanks, I’m very new to UE4 but I have 6+ years of software development.
Here is a screenshot of what I’ve done so far (notice the yellow outline around the chair)
