Isn't this fun?
You should be seeing tiny little white lines, and those are lasers pinpointing where you are to detect when it's time to jump out to the next portal. I'm sorry for that.
You also can't just make an object and expect the portals to push the object around instantly. I imagine with lasers that there's a way to grab the specs for every single object that jumps in front of a portal and apply the code that you need to each object, but I'm just not sure how to go about that right now.
Tell me if you see any bugs, like cockroaches, ants, spiders, or whatever. And if you know a better way to write this script, share it.
