Yes, because everything is sucked in portal in (Creating Velocity), and spits it out.

@petrol
Also, cracker64 used the code from BHOL and WHOL to make the portals, thats why it does that.

cracker is a smart cookie lol i wouldnt of thought of that so the means they both create volocity i think they have weaker pulling and pushing powers though test it like this

d=dust
-=space/nothing
pi=portal in
po=portal out
w=white hole
b=black hole

pi---d---b to test out the diff between portal in and black hole see where the dust goes (in bhole means bhole is stronger)

po---d---w to test out the diff between portal out and white hole see where the dust goes(towards portal out means whole is stronger)

Spell right if you're going to post. And yes, because elements are sucked in, and then spat out.

@jacksonmj
that is some thing i cant do since
1.i cant find powder.h
2.visual studios is not working on my comp

@jacksonmj
powder.h has nothing to do with pressure. It can be found in powder.c. Get your facts right.

@Candunc
no in powder.h is where you enter how much pressure you want to emit:
it goes:
//Name Colour Advec Airdrag Airloss Loss Collid Grav Diffus Hotair Fal BurnExp Mel Hrd M Weights Section H Ins Description

Hotair is how much pressure you want it to make e.g.

WHOL has 0.010f
BHOL has -0.01f
PRTI has -0.005f
PRTO has 0.005f
