I'm really excited.
I wanna see!

[winner]

It is probably not too exiting because it doesn't have color and you haven't been struggling with it for the last several days, but here it is.
The central square pumps 9 units of water in each tick, 'z' switches between water view and flow view and the rest do what you're used to.
How the codes works is for each tile it counts the number of spaced it could move to, and if it has enough water, it does so.

Pretty cool.

[winner]

It absolutely zips along channels and walls because it means the water doesn't have to get as high to continue.  When I gave it gravity it made it's own channel with stationary high water on the edge and moving shallow water in the center.

[Hippoman]

you need to add this all into one giant simulator, but with different numbers for the different parts.
Like for water part, you press one, ants is two, and sand is 3 and so on.

It is probably not too exiting because it doesn't have color and you haven't been struggling with it for the last several days, but here it is.

I'll get to it, I'll get to it.

Sorry, I'm having a bad day.
Not really in the mood to program.

EDIT: I was talking about the color.

[Hippoman]

I'll get to it, I'll get to it.

Sorry, I'm having a bad day.

I was talking to him....

[Outcast Orange]

So was I.

[winner]

Because when I reread it it wasn't as clear as intended, I was poking you about the color so you didn't forget. But incase there was confusion, the "struggling with it" part was about me spending this week trying to figure out what was making water act differently than I expected.

[Outcast Orange]

I thought so.

Things are all okay, and I'll be tinkering with that program of yours soonish.
As soon as I get into the programming mood again.
I know, I'll just talk to Lutz on MSN for five minutes. ; )

Sorry Lutz,
 it's probably not your fault that you give me a migraine.

[Hippoman]

So was I.

oh, shoulda quoted it.

[Outcast Orange]

I did quote it.

I'm going to see if I have a color example ready, and if not,
 I'll make one.
That way I don't feel so bad about working on my game.

[Hippoman]

I've tried but your code is way too...I'm not sure.
Either way I can't figure it out, how'd you do real time?

[winner]

I've tried but your code is way too...I'm not sure.

are you talking about my code? I can try to explain it if so.

Yes. You made it real time. It doesn't wait for the player to do anything, it moves on its own.
I tried adding it into my game but it doesn't work.
