pixi's Issues

Zig semantic analysis fails on case-sensitive filesystems

/home/nixigaj/dev/exp/pixi/src/pixi.zig:52:30: error: unable to load '/home/nixigaj/dev/exp/pixi/src/Settings.zig': FileNotFound
pub const Settings = @import("Settings.zig");

This can be fixed by changing this line to pub const Settings = @import("settings.zig");:

pixi/src/pixi.zig

Line 52 in fc3029d

pub const Settings = @import("Settings.zig");

or changing the name of settings.zig.

OS: Fedora 38 with XFS
Zig version: 0.12.0-dev.297+d2014fe97

Configurable Hotkeys

I tried to give this a shot early on, and Hotkeys.zig holds all the current default hotkeys. We will need to add a section in the settings to configure and change these hotkeys and save them with settings.

Settings do not get saved currently

Need to come up with a good way to handle user settings and saving between sessions. Likely something similar to how we handle recents and things like that.

crash upon value change, animation

Changing the starting and total frame number exits the program.

system-sdk: I can still see a symlink there

Looks like there are still some symlinks in zig-gamedev/libs/macos12:

For example:
https://github.com/foxnne/pixi/blob/main/src/deps/zig-gamedev/system-sdk/macos12/System/Library/Frameworks/ApplicationServices.framework/ApplicationServices.tbd

Please make sure to delete the entire system-sdk folder and copy it again from zig-gamedev.

Bucket tool changes colors across entire image, not just the selected sprite

When using the bucket tool, it affects the entire image, not just the chosen sprite. I'm not sure if this is intentional behavior or not

fabs no longer a zig builtin

zig changed fabs to abs, which has broken dear pixi. I have fixed it and submitted a PR #38

hope its helpful, thanks dood

Investigate magenta flashing screen on macOS on file load

• "You can create an empty texture and then fill it with writeTexture(). You can also create a mapped buffer, fill it on the CPU side and then copy it to the texture with copyBufferToTexture()"

Allow copying tiles/sprites from one file to another

I'm not sure exactly how this should go, as files are likely to contain different tile sizes, but it would be very nice to be able to copy artwork from one file and paste it in another.

Problems building on Linux

Hi,
I tried to build on Linux, but so far no success.
The problem seems to be in the compilation of the src/deps/zip/src/zip.c file.
I tried to play around with the compiler flags in src/deps/zip/build.zig, but so far I didn't have success.

Building with --verbose gives the following output:

I'm using zig v0.11.0 and run a pretty standard ubuntu 22.04 installation.
Any help in resolving this would be greatly appreciated.

[macOS] Window freezes and flashes magenta unpredictably on random file loads

This is a long-standing issue since moving to zig-gamedev, I'm unsure of the cause and it seems to be rather random, some file loads trigger it and some don't, and not the same files every time. It can be forced to happen by loading many files, i.e. packing a full project.

I suspect that the issue is related to this, however, I'm unable to verify yet until the dawn lib is updated.

I did try to debug the application using Xcode, which did at least reveal the following error messages:

Use case: Tiling visualization

It would be useful to be able to have a way to visualize how a sprite would look tiled. This would be very useful for things like creating tilesets

Document Zig version

Looks like a cool project. Could you document which version of Zig can build this project and include that in the README?

Maybe you can add gtk-3 requirement in README?

colorwheel hue snaps back upon color change

If the color is not changed from the last value, then the hue ring just goes back as nothing happened.

Allow resizing, but via adding/removing rows/columns

I've been considering allowing file resize, but with respect to animations and sprite names, this could get messy quickly.

As .pixi files are typically much larger than they have to be, and new files can be created easily to allow more sprites to the final packed atlas, I think the best way to allow "resizing" of the whole artboard is to go with an approach that allows you to add/remove rows and columns. This would need to create a new image per layer and copy/edit the artwork to the new image without destroying all previously created animations.

Selection tool

One critical thing is adding a selection tool so it's easy to copy/paste parts of an image around. This is decently complex, as we will need to track changes for history as well as making sure we don't break other tools.

Currently, all that is available is copying the selected sprite to another tile (ctrl/cmd + arrow keys) or shifting the currently selected sprite (shift + arrow keys). Shifting isn't perfect as it leaves existing pixels as they are when shifting.

I think I like these quick keys for copying sprites, which comes in handy when creating and editing animations, but a proper selection tool would be really nice.

How to create a new file?

I'm on Linux and I think I don't see anything to create a new file? I feel like this is a dumb question but I don't know how to start drawing. I can only import existing png images

Allow different pencil cursor sizes

I haven't really looked into this yet, but it would be really convenient to allow different pencil sizes for larger artwork.

Currently, only the single pixel the cursor is on is drawn. I believe we could track pencil size and allow larger draw areas which expand around the currently hovered pixel.

Just as a note: currently the "preview" of the pixel to be drawn is just an additional hidden layer.

Update to latest `mach-core` and `mach-sysgpu`, and nominated `zig` version

Currently mach-core has disabled sysgpu until further notice, which we need for stability on macOS. There is also a crash on build with sysgpu enabled on Windows for the version currently used in Pixi.

We will be frozen on this version until sysgpu is reenabled in mach-core.

For now, Windows/Linux users can build and run using zig build run, and macOS users can build and run using zig build run -Duse_sysgpu=true.

Change of color selection automatically swaps current tool to pencil

Proposal - Allow specifying name and export location of the generated atlas file

It would be nice to have some functionality which would allow you to specify where the atlas file is sent to, and what it is called
