How to create node that moves in random direction, but stays that direction forever?
I'm creating a game using swift SpriteKit, and I am trying to have enemies that spawn during intervals. I want them to start at a random position and move in a random direction. However, once they move in that direction, they keep going straight forever, continuously bouncing off borders and remaining a straight path. I'm not quite sure what code is needed for the random position and the random direction. Please help!
