Examining the code shows that the rectangle is drawn winding counterclockwise, starting
with the top left. Therefore the colors used should be in the order: topLeft, bottomLeft,
bottomRight, topRight.
However, the variables actually being used are topLeft, bottomLeft, topRight,
bottomRight. I was confused by this as I was getting striping where I didn't expect any.
Put another way, the last two parameters are misnamed.
This diff swaps the parameter names and their usages. The result is that no runtime
behaviour changes: the same parameter order yields the same visual result both before and
after this change, but the parameter names now correctly reflect what they are actually
used for.
You can actually see this in the implementation of DrawRectangleGradientV, which
(correctly) passes top, bottom, bottom, top to DrawRectangleGradientEx.
build.zig doesn't support the examples for the emscripten OS but it does
support the raylib library. However, the examples panic if emscripten
is configured which prevents it from building the library. I've replaced
this panic with a fail step to fix this.
I believe it makes sense to only do this when there are no known
touch points. I am not even sure if this should be done at all.
See https://github.com/raysan5/raylib/issues/4872 for more information.
Previously, the libc paths file `android-libc.txt` was written to
the folder from which the user ran `zig build`. This caused
problems when using raylib as a dependency in other zig
projects, since raylib is not built in the project root, but the
`android-libc.txt` file was still generated in the project root. The file
should now be generated in .zig-cache, which should fix the isssue (and
leave the project root folder cleaner).
Added an Android target to the zig build script.
This allows a user to easily build with only Android-supported
libraries.
Library paths are automatically inferred as much as possible.
