This is a fun little simulator for gravity.

Touch and drag to fling planets around.

If they crash, they disappear.

Try to get them to orbit each other!

Nice and smooth. Hard to „Play“😬😀.

I got an Error if i add to many Planets.
„Index Out Of Bounds
IF PP (Q) = 1 THEN“

Interesting thing :)
Looks like you had problems creating the screenshot. On iOS just use the in-game menu to "Capture Program Icon", then it appears in iCloud Drive.

Very fun :)

You could improve the appearance a lot by adding a stars background. Just saying :)

was8bit 2018-10-31 13:33 (Edited)

Also, maybe let them bounce off each other a few times before they go... the fun doesn't last very long as is.....

Thanks for the suggestions! I added a starry background and a better bounds check for the array to prevent that error.

gtolle 2018-10-31 15:33

Also, Timo, does the IF statement do short-circuiting or not?

For example, if I ran “IF Q < MAX AND PP(Q) = 1 THEN...” would the PP(Q) lookup happen even if Q is greater than MAX?

No it doesn't cut out early, and yes it checks all conditions .. I just tested and this produces an out of bounds error... great question :)

I wish it did, but it was complicated to implement. Maybe I will try again.

gtolle 2018-10-31 19:23

Got it! Thanks - this is an awesome project.

This needs a little update to work with v0.11.
