| convert from hbitmap to bitmap? allegro 4.9.19 |

I know how to read the resource files. I have had help with this before but that was for allegro 4.2.2 and now I am using allegro 4.9.19. I was wondering if any of you guys know how to do this as the last one called <allegro.h> from the old one. Edit: |

You'd need to convert all of the Allegro 4 api calls to Allegro 5 api calls. It probably won't be hard, but it may take some time to learn the new api. -- |

Dammit Can packfiles be read from allegro 5? |

Desmond Taylor said: Can packfiles be read from allegro 5? That code just uses PACKFILEs as regular files, so yes. You can use the new "File I/O" api. It provides everything and more that the old api did (except built in compression, you need to use an addon like physfs, or zlib manually to get that). -- |

I really need to use allegro 5 with my project as I'm trying to make an Endless Online clone. |

Converting my code from A4 to A5 should be pretty easy. It uses the A4 packfile routines, but it's not loading from a packfile but from a regular file. I used the packfile routines to ensure that the correct endianness would be used on all platforms. In most the A4 command name can be just substituted with the A5 one: pack_fopen() -> al_fopen(), pack_igetw() -> al_fread16le(), pack_igetl() -> al_fread32le(), pack_getc -> al_fgetc edit: Oops, accidentally clicked Add reply before I'd finished. The pack_fseek() calls can be replaced by al_fseek() calls, but you'll need to add a third parameter (which in all cases will be ALLEGRO_SEEK_SET). Likewise, create_bitmap() calls will need to be replaced with al_create_bitmap() and putpixel() with al_put_pixel(), etc. Mostly it's just going to be the file IO commands that need replacing, since they make up the bulk of the code. If I have some time this morning, I'll try converting it all over to A5 myself. It should be a bit quicker for me to do it since I'm familiar with the original code.

Cheers LennyLen, I will keep an eye out for your A5 version. I'm definatly gonna add you to the credits for doing this. I tried to convert it but failed |

I've attached the A5 version. Here's an example of using it: 1#include <stdio.h>
2#include <allegro5/allegro5.h>
3#include <allegro5/allegro_image.h>
4#include <al_load_PE_bmp.h>

Dude your a star, That should get me working on my project again, I had to use resource hacker to get the bitmaps juat to develop now to edit my code and use the resource files itself. That will be easier since I'm making an Endless Online clone project. Hence the *.EGF files. Custom map files. It's gonna be a very big project EDIT: EDIT 2 1! C:\Users\Desmond Taylor\Desktop\Web Downloads\al_load_PE_bmp.rar: CRC failed in load_PE_bmp.c. The file is corrupt
2! C:\Users\Desmond Taylor\Desktop\Web Downloads\al_load_PE_bmp.rar: Unexpected end of archive

One thing I'd suggest you do is extract all the graphics from the .egf files and either store them in directories, or in a more sensible archive format. Since you're working on a clone rather than a EO tool, you don't need to keep them in .bmp format either, so you can convert them to PNG to save space. edit: I reattached the archive in .zip format. For some reason, any .rar files I upload here seem to get corrupted. edit2: I've never used .egf files myself (the whole idea of using a portable executable to store images seems absurd to me). I wrote those functions for someone who was making an EO map editor.

Since you're working on a clone rather than a EO tool, you don't need to keep them in .bmp format either, so you can convert them to PNG to save space. The reason I'm using the Endless Online egf files is because I cannot distribute the egf files with the game. I will have to give instructions on where to download them as Arvid will have a hissy fit on me. He is very proud of his artwork and won't give permission to use it. If I tell people to download the original EO Client from the official site and rip the GFX he can't have me for it EDIT: Ahh, Sausage is making a map editor but he's using allegro 5. I have his source code but his conversion makes no sence to me at all. His code is also like 1al::draw_bitmap();
I dont get how he made it point like a class but hey. EDIT 2: 1al_set_new_bitmap_flags(ALLEGRO_MEMORY_BITMAP);
as it made my FPS suck. Without that line it does the job alot faster and without loosing framerate. |

Desmond if you want to know how Sausage is making his into classes then download his eoserv source and take a look at it again. I am pretty sure he used a lot of class developing just like that in there. |

Well you was busy and i was already rambling on. I still haven't been to sleep. That shot I got really did keep me up all night. I go to school in 2 and a half hours. Srry about going off topic. |

Desmond Taylor said: as it made my FPS suck. Without that line it does the job alot faster and without loosing framerate. Yes, it will definitely work faster if stored as a display bitmap instead of a memory bitmap, which is why I would suggest anyone who uses the current code converts it to a video bitmap as soon as possible. The reason I load it into a memory bitmap however, is so that the function can load images that are larger than the maximum texture size. As far as I know, none of the EO graphics come anywhere near this size, but if it gets used to load graphics from modded .egf files, these possibly could be large enough. So as a matter of robustness, I'm only using memory bitmaps.

How would you have to go about converting it? Cause when I look at it, I just kinda stare and wonder what everything does. I bet that if I actually sat down and looked at everything for awhile I could get close. |

where it says 1al_set_new_bitmap_flags(ALLEGRO_MEMORY_BITMAP);
Change with 1al_set_new_bitmap_flags(ALLEGRO_VIDEO_BITMAP);
or keep it as it is and clone it to a VIDEO BITMAP like I did |

I've highlighted here how to convert the memory bitmap returned by my function to a video bitmap. 1#include <stdio.h>
2#include <allegro5/allegro5.h>
3#include <allegro5/allegro_image.h>
4#include <al_load_PE_bmp.h>

, Gonna have to learn alot then. I have a basic sprite moving arround the screen with keyboard events at the moement. I have bookmarked this
