Its a blueprint derived from “Actor”, with a sphere component and a decal component. If you go to the blueprint components part and look at the “add component” dropdown you’ll find decal. Basically I set everything to 1 in terms of scale on the decal and the sphere. Then I have a blueprint tick that scales up the whole thing over its lifespan.
I’ll post an update soon-ish, but basically the scan is a “ping” that can be reacted-to by a bunch of other classes. In the initial case, I have a “PingSpawner” class which spawns another object when the ping overlaps it. The idea being that you “ping” the world and underneath the world (from the LD theme being “Beneath the Surface”) a bunch of creatures exist, so when you ping them you uncover new items to interact with. But of course some of those things aren’t quite so friendly.
I was going for a “Journey” kind of thing with it. So it’ll go in that direction a fair bit. My plan is to play around with different kinds of ping-instigated interactions. Maybe have different amounts of energy required to ping with, or a “build up” of ping energy or something.
Anyway, glad you like it. Probably wont release it until I’ve figured out something a bit more fun in terms of interactions, but I’ll post some more vids as and when I find some new things out.
