how to make balloons or bubbles with different color keep floating randomly

PandaParents

Hi, I want to make balloons or bubbles keep floating. I know how to make them moving up using accelerate , but once they leave the scene, they never come back. I also cannot make them float randomly. I only know how to make them start floating in a fixed location every 5 sec using the timer, so it doesn't look very good. Thanks!

You could increase the game area (screen area stays the same) and turn on the wrap for x and y so that when a balloon goes off screen it will come back in the other side. And add a random timer on the balloon that would change its acceleration every x amount of seconds, even randomize the direction. For things you don't want to wrap, add collision to them with (non movable) borders around the screen area.

Thanks! That is exactly what I wanted.
