Pokitto is on the way, what games should I make?


#121

@drummyfish

Or borrow @FManga’s makefile and possibly adapt it.


#122

@drummyfish : this is what I mean that the optimization begins when all the self-evident stuff has been used up.


#123

@drummyfish

Just ran the demo on my pokitto. Very, very cool. This may turn into a low-rez doom. Looking good.

Edit: but I would do the fog with a color ramp instead.


#124

Yes, or TES Arena. I’d hope it to become an engine for multiple games rather than only one :slight_smile: Once I add texturing and ceilings, it should start to look like Doom.

Definitely, once I get mode 13 to work :slight_smile: Somehow it still doesn’t work for me in the simulator now.

Thanks @FManga @jonne @Pharap for the advices! I’ll have to set up an offline compiler now.


#125

If you want to have something with a lot of contents, keep in mind it’d be best to load it from SD card too. I didn’t saw too much games here relying on external files yet?


#126

That is probably because we have plenty of ROM compared to what we can load to RAM (36 kb) at once. But yes, there are certainly use cases where loading from SD has advantages. E.g. @spinal has been streaming video from SD :slight_smile:


#127

This is what I’d like to do. I’m testing it out, but doesn’t work :expressionless: It needs .o files, so I need to compile the lib first? How do I do it?

The only build system project I’ve found is POKITTO_SIM/Pokitto_sim.cbp – am I supposed to build this in order to get the .o files? It seems to be a Windows-only project since it doesn’t build for me, I needed to modify the compiler flags and now it’s trying to link in Windows stuff… should I bother continuing this, or is there a simpler way?

EDIT: Managed to compile the cbp, but it’s not what I need, just a simulator (doesn’t work when run BTW works now), not the HW library.


#128

It will create a BUILD folder with the .o files on its own. You just need to have a .o entry for each c/cpp/s file in the project.
In this case, your folder should contain:

  • game.cpp
  • raycastlib.h
  • PokittoLib (I use a symbolic link so I don’t need to have a copy of the lib for each project)
  • Makefile

#129

It creates the BUILD folder, but then says this:

make[1]: *** No rule to make target 'PokittoLib/POKITTO_CORE/FONTS/TIC806x6.o', needed by 'HelloWorld.elf'.  Stop.
Makefile:22: recipe for target 'all' failed
make: *** [all] Error 2

If I commend out the TIC806x6.o in the Makefile, it can’t find the next one etc.


#130

That means it can’t find PokittoLib/POKITTO_CORE/FONTS/TIC806x6.cpp.
Here PokittoLib refers to the Pokitto folder inside the lib’s repo, not the entire repo.


#131

It’s doing something! Thanks :slight_smile: Will report back soon.

EDIT:

Yep, compiles, the screen bug is gone, seems to even run faster. However, when I run the program, it’s something completely different from what I see in the simulator :smiley: There is no fog, I can’t go up and down and the map is different. This blows my mind, I have to investigate what’s happening.

EDIT:

Works now! I had an old version of the raycastlib around that got included instead of the new one.

EDIT:

However mode 13 is not working for me in the simulator (shows just a black screen). I tried both this and this. Official examples of mode 13 aren’t working either. Mode 15 is working.

yet another EDIT:

Trying out the emulator – good new is it runs. Bad news is that I can’t compile mode 13 to bin – when I put #define PROJ_SCREENMODE 3 to My_settings.h, compiler says

../PokittoLib/POKITTO_CORE/PokittoDisplay.h:205:107: error: 'LCDWIDTH' was not declared in this scope

(If I define it, there are more undefined macros.)


#132

try #define PROJ_MODE13 1 instead.


#133

#define PROJ_SCREENMODE MODE13

This one worked.

EDIT:

Still it only has 16 colors in the palette, others are black, whatever I set them to. It’s like that even when I upload it to Pokitto. Anyway, I’ll work with 16 colors for now :smiley:


#134

That is not right. The right setting is

PROJ_SCREENMODE 13


#135

Tried that one too, it does the same thing. Also, why does it say PROJ_SCREENMODE = 3 here?

EDIT:

Summary
unsigned short pal[256];

...

p.begin();

for (int i = 0; i < 16; ++i)                                                    
  pal[i] = p.display.RGBto565(255-i,255-i,255-i);

p.display.load565Palette(&pal[0]);
...

uint8_t a = 0;                                                                  

for (uint8_t j = 0; j < 88; ++j)                                                
  for (uint8_t i = 0; i < 110; ++i)                                               
  {                                                                               
    p.display.drawPixel(i,j,a);                                                     
    ++a;                                                                            
  }

Fog with ramps instead of dithering:

EDIT:

Also WOW, I’m getting 50 FPS now! I turned on -O3 plus applied @FManga’s tricks. (I guess it could go even higher – I got 25 FPS when I had target set to 30. Now I have it set to 60 ang get 50.)


#137

I usually set the fps target to 255.


#138

We know you are a hot coder but isn’t that bragging just a little bit over the top? :wink:


#139

ceiling are working (now it’s just mirrored floor):

out6

EDIT: Also mode 13 somehow works now, so I can start working on texturing.

So much better with more colors!

#140

And we have texturing :slight_smile:

You can see quite the aliasing in this one, MIP maps would help, but I’m afraid of performance. Haven’t tried Pokitto yet.
