For some reason it was easier to fly this time around? Anyway I found you can get stuck under the magnified picture:

Yeah, there's a few ways to get stuck. Another one is just going into the side of a wall. One day I'll spend time fixing that.

Ah! Just figured out that landing on the pad too fast is bad... Doh! It's a good thing that I have 'plenty' of fuel... Nudge. Nudge. Wink. Wink....

Aw! I did not see 'that' one coming... lol If ever you decide to add a scoring system, I have seen this style of game many years ago, where the narrower the landing pad the higher the score: eg: Wide pads 50 points; narrow pads 100+ points or you could be the 'nasty' person who includes a simple particle system and enjoys watching players crash and burn... Moo Ha Ha....

(This post was last modified: 09-12-2022, 02:48 PM by james2464.)
Latest version: more bells and whistles added.
I tried a bunch of new things with this version. For example my first use of _Function. And I started to condense the program while simultaneously adding a bunch of non condensed stuff. Haha, still work to do. I'm still wrestling with Sub/Endsub, _Display/_AutoDisplay but I've learned quite a bit more since the last update. Even worked out how to create, copy and rotate small images. And managed to work out some collision detection. Cheers.
