I'm going to start porting the particle engine!

Post by **Falco Girgis** » Thu Dec 02, 2004 5:00 pm

I'm in a really Dreamcast-y mood right now, and I want to do something with C++. I guess NEStix is on a pause because what I think needs to be done can't be until the level editor is done, and what JSL thinks should be done -- who knows, he hasn't said. We just know he does think "something" must be done. (What what what!?! JSL! :spin: )

But anyway, that particle beta we made for NEStix with SDL on the PC. I'm going to try to port that to Dreamcast tomorrow. It'll be awesomeness * 10 on DC. I'm going to use it in the DC Shooter later on anyway.

I have a huge research paper due tomorrow and I haven't even started. I doubt I'll be doing any PC -> DC porting tonight :?

Tomorrow I should get pretty far though. The only things that need to be changed are the SDL rectangles to PVR untextured quads and a few other things. I'll be fun.

Lord, time to go work on the research paper...

Finally some action in the DC forum!

I'll be on all night if you need some PVR lessons. :spin:

Thank you master Tvspelsfreak.

I started trying to use the blood engine with the DC Shooter that I'm making. I seem to of really lowered it down. I have one error.

Tvspelsfreak, if you're reading this, can you tell me WTF this means?

shooter.exe - 1 error(s), 0 warning(s)

Check that out. I reduced everything to 0 warnings with just a mere error.

Evidently it is here:

Code: Select all

 union
    {
      struct
        {
          unsigned int _rand_next;
          char * _strtok_last;
          char _asctime_buf[26];
          struct tm _localtime_buf;
          int _gamma_signgam;
        } _reent;

I thought maybe I should open up C:/DevKitDC/include/newlib-libm-sh4/sys/reent.h and see just what line 183 was. :watiff: But ... uhm... Obviously that's too deep for me.

Tvspels told me to comment out the line that was acting up and now it works. I have the blood engine on my DC Shooter game. It's so much cooler on DC than it is on PC.

Also, I was trying to crash my Dreamcast (shame on me), so I tried to raise the intensity to 3,000. That's actually 3,000*4 because four players and they all got shot at the same time. I was amazed, but the dreamcast didn't even slow down a bit. it just worked perfectly. I love t3h DC.

I'll put up some screenshots later. I'm going to work on it more tonight.

And that's with the worst kind of PVR rendering, imagine if you were using direct rendering. :spin:

3000*4!!!!!!! NO WAY! There must be some type of calculation error.

If you take (3000*4) and mulitply by say 3 to compensate for the data required by the blood class vars, wouldn't that exceed DC's 16mb limit???

I'm confused.

Ok, I dunno what the blood class looks like but let's pretend it's 5 floats.
5 floats * 8 bytes each = 40B
12000 particles ~ 480KB

16MB would be pretty extreme.

But if you were to um uhhh.... um... Oh yeah I don't know how to do C++

Forget i said that, i guess I was thinking about kilobytes for some reason.
