Okay, I changed the deadline, 23 days should be enough for everybody. Do a little each day or something like that.

Download my first mockup with the moving player :P

Nice. I vote you use the space key for jumping. That was just the key I kept wanting to hit..

Yeah, I added jumping now. Working on detection and thats a biatch :P

Edit: Damn, I need to change my detection system to a getpixel system. So it will check for a certain color like rgb(0,0,0). And if that color exist under him then he wont fall.

I'll participate!
I'm not the best graphics designer but I'll do my best with paint! :D
I'll try to finish it on time... but I'm totally out of time right now, because I'm on M$'s Imagine Cup and I don't have much time to program in VB right now...
But I'll participate!
BTW, where is my trophy??????

If I get a free few hours, I might toy with it. I'm working hard-core on MSSC right now though :)

Funny, I actually just started a project that is a side-scroller like this. I don't have to release the source or anything, do I? :wink: Hopefully by then I'll have NPCs done and a very simplistic stat system.

Does MMO support give me bonus points? :lol:

I'd like to give it a try. If I don't finish on time, do you want me to just release what I have?

You mean for the competition? Nobody got a trophy since there was so few participants, hopefully next time there will be more.

Glad you guys join, and remember that it needs to be made by you. So no base sources.

Test it out. You can now:
    - Jump
    - Fall
    - Walk on upper tiles

Post subject:  Re: VB Mario Contest
it's awefully slow. Also, if you stop moving left/right while falling, you stop falling. Then, when you start moving again, you magically warp to the ground. The ability to jump while moving would be nice.

Post subject:  Re: VB Mario Contest
Yeah, the thing is Im using getpixel to see if the pixel is black, if so you cant move. And for that to work you need to move only 1 pixel each step. It would all be better with a map editor, but thats too much time for me to make.
Author:  Spodi [ Mon Oct 08, 2007 5:22 pm ]
Post subject:  Re: VB Mario Contest
Well what you can do is run a loop through every pixel he moves through instead of just moving one pixel at a time. For instance:

Code:
Dim StartX as long
Dim ToX as long
Dim i as long

'Move right
for i = StartX to X
if GetPixel(i, UserY) = RGB(0,0,0) Then
   'The user stops here
   ToX = i
   Exit For
end if
next i

UserX = ToX


Pixel collision, though - badass. Wish I could say I was doing the same. I had to go for grid-based attributes (ie collision) since the server has to be able to process it quickly if I want it to run at any decent speed.

How are you drawing? BitBlt? I just saw a little tearing so I figured it wasn't DirectX.

Seconded.

Mario uses grid detection, too. I wouldn't bother doing it pixel by pixel ;-;
Author:  William [ Mon Oct 08, 2007 5:59 pm ]
Post subject:  Re: VB Mario Contest
Great, idea about the collision detection, no need to check each step. But instead run a loop and store the closest wall into memory etc..

Just using bitblt for the bkg, and transparentblt for the player. Just the very basic.

Its for fun, since then you can draw your maps in photoshop.

Post subject:  Re: VB Mario Contest
Crap, this is what I made:

Code:
Public Function CanMoveRight() As Long
CanMoveRight = 1000
Dim x As Long
For x = CharX + 32 To frmGame.Map1.Width
    If GetPixel(frmGame.Map1.hdc, x, CharY + 16) = 0 Then
        CanMoveRight = x
        Exit Function
    End If
Next x
End Function

I keep changing my ways of doing things in my game, so I think I will have to start all over again cause it all gets to messy.

Heres what I got so far:

http://www.vbgore.com/temp/platformer.wmv

Just did the NPCs today/yesterday. They randomly spawn on the yellow attribute tiles (spawn tiles). Have yet to add a place to define what NPCs spawn and how much per map, though. This is just 1000 randomly-moving/jumping NPCs. Theres two types of tiles - platform, which you only have drop-vertical collision on, and blocked, which you can never occupy the same space as (not shown in this).

The bandwidth usage is a bit insane*, but then again what do you expect from 1000 constantly-moving NPCs. As far as performance, the NPCs take about 0.00003 milliseconds to update individually for the collision information, and all-together the server uses about 2% of the CPU with all this going on. Not bad, not bad. ;)

*Just realized you can't really see the debug info. The bandwidth in is like 7+KB/sec, including packet headers.

Post subject:  Re: VB Mario Contest
Do you have a server, since you mentioned packet header? And also, did you make a map editor?

Looks very good though, can't believe you made that all so quickly.
Author:  Spodi [ Thu Oct 11, 2007 6:07 pm ]
Post subject:  Re: VB Mario Contest
Yup, its all multiplayer. The server keeps track of every client/NPC's movement, and they stay in sync with some Dead Reckoning algorithms along with just using the same physics. And yup, theres a map editor. :wink:

I'm getting paid to make it, so its all of my time. :wink:
