I’m trying to figure out how to randomly generated platforms, like doodle jump but x axis. And also, how to speed up and slow down when the player touches an “accelerator”, for instance, an helicopter, rocket, spring, cannon, etc.?
For speed up/slow down, just have your accelerator object/powerup/etc modify the player’s max speed or acceleration, whichever you prefer. Those items are all accessible as long as you have the platform character behavior on your hero object.
