I remember someone(genevrier , I think , but I can't find the post so I might be wrong) asking how to manipulate gravity. Well I decided to look into it today (because I had lots of free time) and I found this function:

Now some interesting stuff is here:

0040E78B |. DC05 40834400 FADD QWORD PTR DS:[448340] ; Main Gravity - 1.7
1.7 is the gravity for type 0 characters. It is stored in 448340 - a constant variable. It doesn't get changed anywhere. If you set it to 1, then gravity is a lot lower and it's cool and stuff  .
The problem is it doesn't affect the other object types  . And it looks like every item has it's own stupid value .
Anyway, just posting my findings  .
Have fun.

Gravity endp
invoke JmpPatch,0040E6F3h, addr Gravity
Grav is the factor by which all the Gravity stuff is multiplied. The function is still buggy (I think I'm multiplying variables I shouldn't be touching ), so some times items don't fall or something. Not sure really . Anyway have fun  .

A bad video showing how gravity is affected when you half it(I know it's not a very good demonstration, but yeah ).

I really think we could use this in the forum mod.
FOLLOW THE RULES!
Rule 1: English only (+10%, 1 week)
The forum is a meeting place for people from any nation to talk and have fun. Therefore, to ensure that everybody is able to participate and understand you, please stick to English with proper spelling and grammar.
Rule 2: Think before posting (+10%, 2 weeks)
Spam (posts that contain literally no useful information at all), off-topic discussion, gravedigs (posting in threads that have been inactive for several weeks) or generally senseless posts (posts that are hard or impossible to understand) of any form won't be accepted.
If you want to ask questions, search the Mainsite ( http://www.lf-empire.de) or the forums first to check if your enquiry has been answered elsewhere.
Rule 3: Etiquette (+30%, 2 weeks)
Generally, common sense applies here. Do not offend, harass, curse, show disrespect, or be rude towards anyone. Newcomers shall be treated, like anybody else, with respect.
Additionally, sexual or illegal content (such as pirated software, plagiarisms) are not allowed and will immediately be removed.
Rule 4: No multi-accounting (+40%, 1 month)
You may only have one single account on LFE. Bans will be allotted upon disregard.
Rule 5: Follow posting guidelines (+10%, 2 weeks)
- As LFE offers you to select differently colored themes, submitting posts with excessive color formatting is strongly prohibited as it possibly makes it hard to read them in other themes.

- Use descriptive titles when posting a thread. “Help” does not tell a whole lot.
- Click the [Solved]-button when a thread of yours has been cleared of your problems.
Rule 6: Follow profile guidelines (+10%, 2 weeks)

^No, but say Genevrier could get it to vary between backgrounds...

maybe we could use that for a special planer with extreme low/high gravity

this is getting offtopic, guys. Talk about such stuff in the forum mod section.
Thank you.
