I'm making a game, where objects fall and you have to try to evade them. I'm using pictureboxes and they fall, and the object is able to move horizontally. The question I had was how do I make a loop so then once the pictureboxes fall off the form, they can spawn randomly (the pictureboxes have different set speeds) at the top and fall again?

Another problem I had was how do I have it so once a powerbar falls down to zero, the game ends, so say the object at the bottom gets hit 4 times, then the power bar falls to zero and the game ends. Those are the last two steps I need to finish the game.

Thanks,
