direction is still based on camera but
you can rotate camera and double click
in diferent direction ( like you show,
but you can rotate camera to choose a
different direction)
In this case, what I’ve shown above should work OK-ish - at least for now. Imagine you’re shooting a 5000 uu long ray from the centre of the screen (camera) using mouse cursor as the target. The red arrow is pointing at where that point would be in 3d space - here demonstrated by the orange sphere:
It’s camera based already - the example above actually has a standard springarm camera setup. Rotating the camera should work fine (untested, though),
doubleclick will set the max speed and
direction of the actor once it
triggered
The velocity is whatever you put into the scale value - it scales and accumulats vectors over the duration of a frame and then applies it to a Floating Pawn Movement component of that Pawn:
The component has some basic variables already but you will, most likely, want to add your own movement methods.
sphere is hollow, is just an image
with stars, planets etc (like
sky_sphere bp where you see clouds)
You can use the existing sky_sphere, sure, and assign your own material to the mesh, you could get decent enough results with something as basic as:
You will need to have some understanding of how materials & cubemaps work:
