gm1konvertercrossplatform's Issues

Every change in tile_buildings2 crash the game

Problem is in a subject. I don't see any log file so I will describe my actions one by one.

1. I've extracted images from tile_buildings2.gm1.
2. I've changed 2 pictures of granary in the "Images" folder on my custom ones.
3. I've imported images and created a new gm1 file.

After all that my game crashes while loading. What have i done wrong? ¯_(ツ)_/¯

Import Animation

Hi! You have mentioned that you know how to do it, but the process of importing goes very slow. So I wanna say you: if it's working with no bugs, I would wait a whole day. Just please release it. We all thank you and wish you best luck. ^_^

All questions on graphics and graphics programs for Stronghold Crusader 1

Hi. Very necessary stripes of lives. I will try to redraw them. Kinh if you can already unpacked files. I will redraw from and then post it here so that you pack them.

The program does not read the gm folder

The program does not read the gm folder

problem

Hi dude !
an error occurs when I want to run program .
"object reference not set to an instance of an object ."
how can I solve this ?

Sprite info request

It would be nice to be able to watch gm1 sprite info by clicking on image. Info like sprite index, its width and height and all other info that game uses. Like this:

Gm1KonverterCrossPlatform/Gm1KonverterCrossPlatform/Files/TGXImage.cs

Lines 21 to 33 in f5f44af

	private ushort width;
	private ushort height;
	private uint tgxwidth;
	private uint tgxheight;
	private ushort offsetX;
	private ushort offsetY;
	private byte imagePart;
	private byte subParts;
	private ushort tileOffset;
	private byte direction;
	private byte horizontalOffsetOfImage;
	private byte buildingWidth;
	private byte animatedColor;//if alpha 1

Maybe show this info only under some kind of advanced or debug mode.

GFX image crash

1. Click any tgx item
2. Select other item using arrow keys (on keyboard)
3. Click on image
   Crash at

   Line 641 in fcab4be

   if (!vm.File.FileHeader.Name.Contains("anim_castle") ) return;

Crash

After some time of switching between gm1 file program crashes. There is no specific pattern and it happens on random file.
PS: game - Stronghold Crusader HD

Grafikbug

define width of bigimagefile exports

make it so that the big image exports can be befined by width to get this result https://i.imgur.com/clw9NUk.png instead of this https://i.imgur.com/zCdlr9Q.png

anim_castle.gm1 crash

Whenever I click anim_castle.gm1 item program crashes.

Line 631 in fcab4be

_strongholdasBytes = File.ReadAllBytes(vm.UserConfig.CrusaderPath.Replace("\\gm", String.Empty) + "\\Stronghold_Crusader_Extreme.exe");

I use it for Stronghold Crusader so I don't have Extreme exe

Possible color conversion issues

For example when manually editing colortable, color is capped at value 248.
When editing, you are allowed to select any value between 0-255, but after you click save and then select the color again, the value is rounded and capped at 248, though it probably doesnt reflect how game works with the colors.

The color is encoded as A1R5G5B5, which means 5 bytes per color, which means 32 possible values (0-31).
It is assumed that the translation between 0-31 and 0-255 is linear, where 0-31 is simply divided by 8 (or 0-255 divided by 8).

The game renders colors from 0 to 255 though, which means the mapping of values is not as stated above, where 31*8 = 248.

I took some screenshots from game and created a map of rendered values.
The map is not 100% complete, but i think it is already clear how the colors are actually mapped and we can safely assume unknown values.

This should not be an issue as long as the conversion doesnt alter appearance of identical file in game through export/import, though i think we should reflect the colors better when exporting the image or displaying color table editor.

Luckily i dont think exporting and then importing an original image will result in color shift in game, as the maximum difference (7) is less than an unit (8) so the value should be rounded back to what it was.
I will do some tests later to see if there are any issues with the conversion, the above is just an assumption.

Export Images as one big Texture like asset and Import for easier Editing?

Hello Guys,

if you have some ideas for the Gm1Converter you can write it here Down.
Monsterfish had the idea to export Gm1 Files like tile_sea8 as one big image for editing, i can add this feature for the next update if you want. Also the bug with the black bars in the preview got a fix, i can implement that too.

Crash reproduction

I was able to reproduce this crash.

1. Select tile_land3.gm1 item
2. Select tile_land8.gm1 item
3. Once again select tile_land3.gm1 item
4. Once again select tile_land8.gm1 item
5. Keep switching between those items. It takes like 10-20 switches until it crash.

It isn't managed .net exception, so there is no callstack. Only this error if I run program under debugger

An unhandled exception of type 'System.AccessViolationException' occurred in SkiaSharp
Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

This is not an issue

Good day to you, i noticed that your readme file is poorly translated (as well as containing some broken links). I can fix it if you want.

Great tool btw

load offset values correctly to prevent continues manual inputs

after patching the game with the ucp the offsets for the overlays resets to the vanilla value it would be great to have the program remember the previously set values or make it so that it has a config that can can be applied via button
(talking about these values)
