Here is an example of a line of code I have
get_rgb (pixel, & red, & green, & blue);
if (blue<201)
I want to use the following colors as well (aside from plain red green and blue)"
orange
yellow
pink
is there some combination or do is it impossible. if you are one of those people that need more to understand. i need more colours to use with collisions.
If I understand, you want get a copy of a graphic but in one solid color, it's true?
If it's, you can use blendop_tine
int bop;
...
bop=blendop_new();
blendop_tint(bop,1.00,0,0,255);
blendop_assign(file,graph,bop);
blendop functions only works with 16bits.
EDIT: maybe you don't mean it... :D
blue, mask area (cant run through it)
red, death
green, next level (but you warp to yellows location)
yellow, previous level (but you warp to greens location)
for now. can you help me with the warp code? i guess to maintain the left and right facing i can make a global variable that is attached to the character so when you go to the previous level you arent facing the default right. hmm.....
its gonna get very hard once i get to placing everything in the level. i wish i could make a code that makes the level load a .txt file (or something) and it knows the placements of everything) when that level loads in game. is that too hard? to me im thinking its just more code for the game but its not in the engine itself. but you are the fenix/bennu master.
sorry, my english is very poor... I don't understand that you ask.
please, if any people can translate it, I'll be thankfull

fixed
via google translator i have recieved the following
azul, la máscara de área (no puedo circular por él)
la muerte roja,
nivel verde, al lado (pero la deformación a la ubicación de los amarillos)
nivel amarillo, anterior (pero la deformación a la ubicación de los verdes)
por ahora. ¿me pueden ayudar con el código de la deformación? Supongo que para mantener la i la izquierda y la derecha frente puede hacer que una variable global que se adjunta con el carácter de modo que cuando usted va a alcanzar el nivel que arent hacia la derecha por defecto. hmm .....
su ir a ser muy difícil una vez que llego a poner todo en el nivel. Me gustaría poder hacer un código que hace que el nivel de carga un archivo. txt (o algo así) y sabe las ubicaciones de todo) que se carga cuando el nivel en el juego. es que demasiado duro? me estoy pensando en su código más justo para el juego pero no es en el propio motor. pero usted es el fenix / gurú de Bennu.
:)
I was use google translate, but I don't understand.
I think that you need check when your pixel is yellow, if you need it, then you need know what values return rgb for yellow.
but, maybe I understand bad.
your english has gotten worse :/ you mean add a red and green like
blue=200,red=200,green=200 (white) that kind of thing?
sorry, I don't understand you... please do not be offended, I do not understand what you say... I can't help you for now, I don't understand that you ask.
I really sorry, please, anybody can help here?
I mean
rgb(pixel,&r,&g,&b);
if ( r == 255 && g == 255 && b == 0 ) then "I have collision with yellow"
if ( r == 255 && g == 255 && b == 255 ) Then I have collision with white
if ( r == g && b < r ) then I have some yellow hue
I don't understand if you ask it.
here you have some rgb colors codes
http://www.avaloncity.com/info/fprefect/spice/colors.htm
well, maybe I wrong and you ask other thing.
sorry if I wrong.
I think he wants to use a map with diferent colors in order to save info about the stage:
blue, mask area (cant run through it)
red, death
green, next level (but you warp to yellows location)
yellow, previous level (but you warp to greens location)
In that case, you must save that map in your fpg, and you can check colors by using map_get_pixel. That function returns the color on a x,y position.
Is this what you wanted to do? :P
the mask has different colors. take for example the metroid fusion debug room. youll see that the dark blue you cant run into but you can run on it (which is blue in my map). in the debug room red is the ladder, i wont have a ladder in my game but i think you understand.
http://www.youtube.com/watch?v=1ZyD9Z3jYfA
I think you're talkting about hardness maps.
What you have to do in that case is use a graphic to display in-game and another with the colors of surfaces, like you said, ladders, walls, and floors that will not be visible by the player.
And then, like Windgate said, check the colour of the second map (the one with the coloured zones) using map_get_pixel function.
What I do is simply count the position of the color index I want in the palette. You can view the palette in a fpg editor. A little primitive, I know.
ok now that we have colors aside, how can i make it so the player warps to a specific color. the green and yellow will onyl be 1 32x32 block respectively so it wont be that confusing to have it warp to a point. but i would like to know how to make it warp to that point. and can someone also teach me how to make a level load a .txt file that is basically more code for that level (the locations of objects). i assume in total this is just a few lines.
How about we make the game for you? Just joking! Lol... The fun part of being a programmer is finding out how to solve different problems you come across in order to make the game or the program you want to make. If you ask us about everything you're missing the meaning of it all. So, my suggestion is: read different ways to do what you want to do and then CODE IT and then LEARN IT, doing that it'll help you become a true game programmer, and a better one with each step you take, don't be a lamer! Keep up with you work! Cheers!
Ok... ive already completed the game controls for items, the menu, the enemies, etc. i just have no idea how to do the .txt file thing. dont be rude and help me witht hat part at least.
If you need collision with some objects (process?) and with other not, you only need add a type (a local var) for the object_type, and then when you collision with it, check this var and do what you want depending the value of this var.
i mean,
#define hard_block 1
#define soft_block 2
#define lalal 999
local
obj_type;
...
obj_type = hard_block;
...
obj_type = soft_block;
...
obj_type = lala;
...
when you have collision
if ( collision_id.obj_type == ... )
...

Agree.
Most of what I've learned about Bennu I've read in the documentation. And the majority of the pages there only has vague descriptions.
well im not like my brain cannot process vague things. just show me a warp code and a way to have a level read a .txt file for where everything is placed for the love of god (or alla or cthulu or buddha whatever your preference is...). the game is virtually done, i just done know warping and the level reading stuff.
for read a txt file, you can use fopen, fgets, and fclose.
I'm not being rude DoctorN, I apologyze if that was your thought about what I said, but essencially that is the way of the game programmer. I have to say that I can't quite understand what is your purpose with that thing of txt files and level uploader. Maybe you could explain yourself better, maybe also add some graphs to help illustrate your request, so that way more people will be able to help you out. Cheers!
the .txt file will contain code of where everything is placed in that level (so the levels image, the levels mask, the itmes, the characters warp point, the character, the enemies, etc). that way it wont be in the engine. now id like to make this a moddable engine (much like with the source sdk, not exactly but along the lines of what they do). i want it so the game engine itself has all the information about all the things running in the game. if i could, i want the engine to load a .txt file (the level structure) that has all the levels in it and that .txt file loads more .txt files (the levels)
Maybe you could use INI files for the maps, i don't if this would be ok, but you can have the list of the objects, and then load it into an array, or something...
To read ini files check this: http://forum.bennugd.org/index.php?topic=2317.0
will it work on fenix? until dc-swat ( a russian guy) ports bennu to the dreamcast (which hes working on, it keeps crashing though) im stuck with fneix.
please, if you need help for fenix, please, remember us it.
in the post title, add [FENIX]
because the solutions can be very differents.
Process scroller(STRING ".\sprites\level\image\level1.txt")
int handle; // handle for the loaded file
int druppels; // here's where the loaded data go
Begin
level_graph=fopen(".\sprites\level\image\level1.txt",O_READ); // opens the file in reading mode
fread(handle,druppels); // reads from the file and puts the data in druppels
fclose(handle); // zipping up after business is done
write(0,0,0,0,druppels); // shows the value of druppels
start_scroll(0,Player_graph,level_graph,0,0,1);//starts the scroll
im confused... am I doing this right? in the text file i just put
level_graph=load_png(".\sprites\level\image\testlevel-1.png");
end
EDIT:
Process scroller ()
Private
int handle; // handle for the loaded file
int druppels; // here's where the loaded data go
Begin
handle=fopen(".\sprites\level\image\level1.txt",O_READ); // opens the file in reading mode
fread(handle,druppels); // reads from the file and puts the data in druppels
fclose(handle); // zipping up after business is done
write(0,0,0,0,druppels); // shows the value of druppels
start_scroll(0,Player_graph,level_graph,0,0,1);//starts the scroll,
Now it loads the game but crashes right after the window appears
The modify button disappeared for me :/ so I cant really add it into the other post but the error i am getting when it opens and then closes is:
El fondo de scroll 0:0 no existe
any second now... i spent all week trying out things but nothing worked :/
It says the front graphic if the scroll doesn't exist. You got to fix that.
How would i fix that though? Do you need the part of my code?
Process scroller ()
Private
int handle; // handle for the loaded file
int level; // here's where the loaded data go
Begin
handle=fopen(".\sprites\level\image\level1.txt",O_READ); // opens the file in reading mode
fread(handle,level); // reads from the file and puts the data in level
fclose(handle); // zipping up after business is done
write(0,0,0,0,level); // shows the value of level
start_scroll(0,Player_graph,level_graph,0,0,1);//starts the scroll, variables:
hmmmm......
The level_graph should be a valid graphic. You need a valid graphic for the front graphic of the scroll. I don't remember all quirks of Fenix, but bad error reporting was one of them. Also check out start_scroll (http://wiki.bennugd.org/index.php?title=Start_scroll)() on the wiki.
Some general tips for debugging:
- insert say (http://wiki.bennugd.org/index.php?title=Say)() statements to check what line goes wrong
- insert verification checks for arguments you pass to functions (for instance, you could do if(!map_exists (http://wiki.bennugd.org/index.php?title=Map_exists)(...)) /* handle/report error */ end on that level graph and this would catch the error)
- back trace from the point where it went wrong to find out what caused the error
that ade no sense :s i contacted this russian guy maybe hell figure it out but that made absolutely no sense. i cant just take what you showed me and apply it to my code because i dont know where and how i should do it. a little more meat on the bone would allow me to understand, yes?
Yeah those error messages. Older versions of fenix (the 0.84 versions) where notoriousely buggy too. I have bitter sweet memories to that version in particulair, because it was the only version with gui.dll wich was nice addition that wasn't developed any further, but it was completely undocumented and very quirky. (It wasn't very hard to make it crash).
Actually I have the latest version of fenix for dreamcast which is the latest version of fenix. What sucks is in order to run the program you need a file manager but ive been talking to the russian guy who ported it hes working on bennu as well.
Anybody?
and ?
Ive been trying to get this to work! Jesus Christ... I wanna load them levels from .txt files ive been trying for a month straight. But nothing is working.
Man xD And how you make the levels ? :D
How exactly are you loading the levels?
Reading data from a text file and putting it in a structt is not very hard, but still I recommend
binary files for the level data itself (kinda requires an working leveleditor), but you can also
save data from a predifined struct to a file. On the wiki there should be some examples of the
load/save routines with structs.
http://wiki.bennugd.org/index.php?title=Load (http://wiki.bennugd.org/index.php?title=Load)
http://wiki.bennugd.org/index.php?title=Save (http://wiki.bennugd.org/index.php?title=Save)
Heres the link to my game
http://www.mediafire.com/?76bbpebs9pss9wa (http://www.mediafire.com/?76bbpebs9pss9wa)
that should sum things up. I may or may not have changed the code back to the levels being loaded in the engine itself but im not sure. The first process is either scroll() or level() either way they are the same thing, I just cant remember which one I named it to when I made the .zip. I want to make it read this .txt file simply places all the objects (collectibles, player, enemies, etc) and makes the level image and mask (which are .png files anyways, it just places them on the screen) and inside that .txt document i want a code there that when the player runs into this object (next_level, or previous_level) it changes to the next (or previous) .txt file (which is the next/previous level). Ill take a look at the save and load thing but take a look and see if what I have invisioned will work.
Yeah I tried the load and save thing it worked without errors but it loaded blank nothingness and the error no scroll 0:0 of doom. please help
Quite obvious that it doesn't work. I looked at the textfile level1.txt
You should not put code in it, just only put the path with filename in it, like this: sprites\level\image\testlevel-1.png.
Then read it with the fgets() function. This function reads just one line of text form a textfile, and it returns the string of text it read.
Don't use fread on textfiles.
Try this to change it into this:
//This process is for all the levels, menu's, and cutscenes
Process scroller ()
Private
int handle; // handle for the loaded file
int level; // here's where the loaded data go
string path;
Begin
handle=fopen(".\rooms\2_Level\level1.txt",O_READ); // opens the file in reading mode
path=fgets(handle);
fclose(handle); // zipping up after business is done
write(0,0,0,0,level); // shows the value of level
levelgraph=load_png(path);
start_scroll(0,Player_graph,level_graph,0,0,1);//starts the scroll, variables:
etc etc etc etc
Anyway change the file level1.txt form
Process handle ()
level_graph=load_png(".\sprites\level\image\testlevel-1.png");
end
into only this (so only one line of text):
sprites\level\image\testlevel-1.png
You can add more lines of text, fgets reads the current line when put in a loop.

Thank you now I added it to my real code (the code I keep secret :3) Thus making the game almost done, now all thats left is:
*pause menu
*playing fmv cutscenes (if thats even possible)
But thats all last minute stuff like always, all the levels have been done, all the enemies have been done, but now that i have an easy way of loading and unloading the levels externally (instead of through the engine) that should make the programming much easier
If I wanted to, could I put in the corrdinate for all the things that will appear in the level and will the unload when that level is done? ill have to do some experimenting. But thanks

Yes, this is possible, in several ways.
You could add more lines in your textfile where each line represents some value (the order of the data matters).
Or you could use the load and save routines on structs. Be carefull though, if you add variables to a stuct later on, you have to resave
the file because load and save routines expect the data to be in a certain order with a certain size. My guess is that strings are saved in a special way.
OK, now to work on that and i think were done here. I still have to go through and debug though and learn how to play .avi files and reformat my pc (sony vegas no longer works :( ). If you have anything please share it :) Thanks
*cough*specifically placing objects*cough*
EDIT:
It seems like I can put in more lines of code but they have to be for an image or for a sound. And when I do that, I can add more lines but for example. Level will also load the mask image and levelmask will also load the levels image, thats a waste of video ram and it messes up the mask. so at the time being i have individual .map (thats what i called them) files for both of the things. I thought I could just make a .map file with this
Player(50,100);
EnemyX(260,100);
pellet(100,200);
pellet(116,200);
pellet(132,200);
pellet(148,200);
and put in the code load them but i dont know what code to use to load them and place them. Also, how can I change the .map file from within a .map file? That way once the engine is fully done I only need to worry about the .map files. Thanks. I also am going to ask if I can have some of the players actions done in the .map file itself because I have an object that I will make called "next_level" and "prev_level" and I guess I can put in the level.map code that when the player runs into it it changes its x (or y) coordinates and then it unloads everything off of the map (excluding the player) and changes the level and places everything where it should be. Any help?
So ive been looking at the wiki at these things
http://wiki.bennugd.org/index.php?title=Fgets
http://wiki.bennugd.org/index.php?title=Fputs
http://wiki.bennugd.org/index.php?title=FileHandle
http://wiki.bennugd.org/index.php?title=String
http://wiki.bennugd.org/index.php?title=Standards:function
But theres 3 main problems:
1. it doesnt show me how i have code that reads a specific line
2. it doesnt show me code on where to place things
3. it doesnt show that i can have code inside the .map file to load another .map file (for example, when the player hits an object changing the level)
remember, im trying to make the engine moddable and I know this can be done I just cant find that 1 easy answer. lol
In this case, you really need to consider creating an editor and use a binary format.
You may look at the sourcecode of my malvado project, wich has an editor.
http://code.google.com/p/malvado-bennuremake/downloads/list (http://code.google.com/p/malvado-bennuremake/downloads/list)
download the developer version, before unpacking, download all 4 of them, then start by unpacking part 1.
The developer version contains both the executable version as well as all the sources.
In order for the editor to work properly, you have to install the included "zenity" package.
One word of caution: the sources are licensed under the Gnu GPL, so if you copy-paste something literally you'll have to
copyleft your program too. There's also a manual included that describes how the file formats work.
Thanks, will there be code inside the game showing where to place stuff?
EDIT:
And what do you mean copyleft? If that means my game is 100% going to be open source then eh. I was going to make it moddable like the original doom was, people just slowly found out they could alter its contents, lol.
Yes, there is code that places stuff in a level. It is a "render"routine (nothing more then a for loop that iterates over the data structure, and that creates the process instances, both the game and the editor do this).
The file "level_init_render_objects.prg" is one of them. When a level is loaded, the routines in the file "clear_levelstruct.prg" are executed first. Please refer to the development-manual in the dev-docs folder for specific details.
With copylieft I mean, that a derived work that uses routines from a gpl licensed program should also be licensed under the gpl. This is very difficult stuff, refer to the free software foundation or wikipedia about the details about opensource/free software licenses. (Basically A closed source program cannot link to a gpl library, but with lgpl/mit/bsd/zlib licenses that is possible. (Just look at the source for inspiration/ideas, and then re-implement it your own way if you keep the source of your project closed).
This game is also going to be commercial since its going to burned to disc and ready to play on the sega dreamcast.
EDIT: looked at it, eh not really what im looking for
All I need is a code that makes it so it reads that line and that line only and a code that reads the location of the objects and places them in the level, and a code for unloading everything and then loading it again for the next level, and a code that loads a .map file from within the .map file (for example, ill have the engine read it when you collide with something as next_map and in the .map file next_map would be the next file that loads) understand?
It is not so diffucult to do. Before you write any code, think about the logic design and the string and file functions you can find on the wiki.
It's temptious to start coding immidiately and design while coding, but trust me, be patient and think throughly about the design. Part of this process is experimentation, you'll learn a lot more this way then by asking us for quick fixes with example code. It took me years of trying, but once I figured out the mest methode I was able to achieve my goal with improving malvado. I must admit, I've been programming with the DIV language for over 10 years. Part of that was actually learning programming in general (I also learned a few things from Pascal and C books and relating that Bennu).
Ok ill think about the code a little more :) im sure the finishing touches wont take that long
