Basically I want to collect items and have them trail behind the main character as it moves through the screen. How would one achieve something like this? Im not sure if I should start a new thread for this, but is there a way to add powerup upgrades via a store system? So if I have a shield that lasts 5 seconds, and I want to purchase a shield that lasts 20 seconds, how would one implement this? I come from a programming standpoint so I can't grasp all the concepts behind Buildbox just yet, I keep thinking in terms of programming. Any help is greatly appreciated! Thanks so much!!
