pSDL v1.0.0

[ruler501]

maybe currently they are very limited though I'm working to try and fix that though there is not much i can do right now

EDIT: forgot i posted this merged later post

First real complicated program on the prizm is a basic fire demo

EDIT: attatched g3a of demo it should work and exit after 2.5 seconds but I'm sorry if it doesnt and please dont hold me responsible for any damage it does to you calc as i have only tested on manager software so far

Looks nice. I hope you can fix all the problems there are.

Looks good! What is SDL, exactly? Is it a new language or a library?

[Lionel Debroux]

SDL is indeed, a library (a set of libraries); it's very portable, and thousands of SDL-based games have been made for dozens of platforms

[ruler501]

Though i think I'll have to port SDL_image so we can use smaller images then bmp(though I'm still not sure if bmp loading works currentlly)

EDIT: since file i/o currently doesnt work I'll find a way to implement the header based images everyone else used for SDL

I need some help getting basic image loading working. I use the two arrays from sourcecoders conversion to 8 bit to create the surface. the image appears to be blue shifted on everything.

Code: Select All | Copy To Clipboard

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28

SDL_Color rgb16to24(Uint16 x) { SDL_Color newcolor; newcolor.b= (x & 0x1F) * 8;         newcolor.g = ((x >> 5) & 0x2F)* 4;     newcolor.r = ((x >> 11) & 0x1F)* 8; return newcolor; } SDL_Surface* LoadSCImage(Uint16* pallete, int paletteSize, unsigned char* image, int x, int y) { int i, j; SDL_Color newColors[paletteSize]; for (i = 0; i < paletteSize; i++) { newColors[i] = rgb16to24(pallete[i]); } SDL_Surface  *tempsurf = SDL_CreateRGBSurface( SDL_SWSURFACE, x, y, 8, 0,0,0,0); for (i = 0; i < y; i++) { for (j=0; j < x; j++) { *(Uint8 *)(tempsurf->pixels + i*tempsurf->pitch + j) = image[i*x + j]; } } SDL_SetColors(tempsurf, newColors, 0, paletteSize); return tempsurf; }

You could use the simple image format I'm using for nSDL. The code is very short (here) and it returns a 16-bit/8-bit surface. It should require no changes to compile, and would assure some sort of compatibility between both platforms.

[ruler501]

I think I will implement that too.
I'll be putting these in a second library called pSDLlib so that my pSDL port remains SDL and pSDLlib is an addition for easier use
thanks hoffa.

Image Loading Cross Post from Cemetech

I couldnt get 8 bit working but heres the function that correctly loads 16 bit

Code: Select All | Copy To Clipboard

1 2 3 4 5 6 7

SDL_Surface* LoadSCImage(Uint16* image, int x, int y) { SDL_Surface  *rimage, *tempsurf =  SDL_CreateRGBSurfaceFrom(image, x, y, 16, 2*x, PZM_RMASK16,PZM_GMASK16,PZM_BMASK16,0); rimage = SDL_DisplayFormat(tempsurf); SDL_FreeSurface(tempsurf); return rimage; }

I'll compile this and a few things from hoffa's nSDL to a seperate library when i came back to work on this in August

[DJ Omnimaga]

Good luck! ALso i watched the video and it looks pretty nice . I hope this allows more games to be easily produced for this calc in the near future.

[ruler501]

I'm back now and now I need to decide what I need to do with this project. I think that one of the main things that will need to be done is get the events to recognize all keys. If anyone knows a way to do this please tell me. I also plan on making some demo's and trying to find more efficient ways to implement some of the internal functions.

What I need help with:
Testing what keys are down for the entire prizm keyboard
Getting file i/o for bmp loading
Getting other SDL libraries working(SDL_gfx most importantly)
If I could get these things working I think it would greatly improve this library

[DJ Omnimaga]

Welcome back. I unfortunately cannot help but hopefully someone can answer in the PRIZM section. You might need to create a separate topic, though, so people notice your question.

[Spenceboy98]

*Necropost?*
I'm guessing that progress hasn't been very good lately?

[ruler501]

I haven't done anything with it since I got back. I haven't really done much coding overall. If there are any problems or requests I'll probably look into it but I make no promises for now

[DJ Omnimaga]

Hopefully you don't stop coding completely
