How should I make an object to be positioned at a random point on the screen and move in a random direction with any angle. It should also collide with the border of the screen and again move in a random direction. How can I do all this?
Use the random block from the Logic and math section. Run the output of the random block into a filter block from the same section. Use the filter block to choose what type of numbers you want and now the filter block will randomly out put true or false depending on the number it recieved.
