How will you find an invisible car in Blockland?
That's what I'm saying.
Getting on it immediately after spawning it, or if you see someone else in it, wouldn't be a problem.
The problem is if you get out of it and lose track of it.
shoot randomly until your bullets hit something you can't see
paint would work too
That's far too time-consuming, no one would actually do that.
I was thinking a temporary emitter, or a temporary change of datablock
A on-screen indicator of direction/distance would be nice, but would require a clientside add-on to be any more specific than "To your left" or "behind you"
