Hello everyone,i just started learning Greenfoot and I am currently trying to instantiate a random number of Actors(some bats) from the left and right of the screen.They have flying animation and I i do not understand how to do that. I have the code for animation in the Bat.class and i think that is one of the problems,should i make an aray of variables so every Bat acts differently? Again,when i instantiate one it works perfect but when i try to instantiate multiple Bats from the left and right of the screen it won't instantiate anything at all.
