Auto Credit Based on DragonTech's aEXP

some text if it fails

This is the first vizzy project I've attempted and somewhat succeeded so I decided to share it.
The goal was to make a program that would land any rocket on droo(non precision landing) and possibly any planet by setting the calculations based off the specifications of the current craft and planet. As of now it would require tuning in order to work with other rockets and planets but the code itself should be the same. Given the landing zone is level, this rocket was able to land consistently starting from any altitude and velocity when autopilot is activated above 4km.

This is still an unrefined an early version so I am aware that it won't perform perfectly everytime. I also am looking to optimize the projected thrust better so it lands faster. If there are any suggestions let me know, especially if you're a vizzy veteran unlike me.

Note: the focus of this craft was the code so I didn't bother to make a fancy rocket.

    I owe credit to Hannah1212 and QarabinaKa as they helped me learn the fundementals of the vizzy blocks I used to make this.
