hy everyone, for my exam this year i had to write a computer game on vpython
(visualpython).we had to make a lunar lander game where the ship drops by
gravity and is able to manouver to safely land on the moon.<br>right now i am
completely stuck on trying to make the visual of the ship rotate.<br>i'm new to
this forum, i guess i'll just paste my code here. Everything works fine on the
game, except the rotation of the ship. however the when you press "up" the
after rotating the velocity actually changes direction , but the visual
doesn't. i'm getting kinda nervous because due date is coming, any help is
appreciated, here is the code:
