By looking for failed start and requesting then;
and then emitting a new event type when
permission has been granted or rejected;
and then using that event in the default
boot.lua to re-start capture.
- The lovr.headset.renderTo callback can now be nil, causing an empty frame to be submitted to the compositor.
- lovr.mirror will still be called if lovr.draw is nil. This means the window will be (correctly?) cleared to the background color now if lovr.draw is nil.
This prevents runtimes from thinking the app is missing/unresponsive when lovr.draw is absent. To get the old behavior, just don't call lovr.headset.renderTo.
- Link against dl (this was probably why ffi.load didn't work)
- Store shared libraries in the apk uncompressed
- Libraries are added during the "package" aapt call instead of "add".
- Because -0 (used to store uncompressed) only works during package.
- classes.dex is added here too now.
- There's only one aapt invocation now, which is kinda nice.
- The lib folder needs to be in a subfolder now ("raw" was chosen).
- Because "package" and "add" subcommands work differently.
- Store shared libraries in the apk page aligned
- Required passing -p to the zipalign invocation.
- This is needed because dlopen("zip!path") needs it.
- android:extractNativeLibs="false" is added to the XML manifest.
- apk sizes are bigger, but disk usage and install time should improve.
- Fix a bug with moving plugin libraries into the lib folder with CMake.
- Use lovrFilesystemGetSource instead of lovrFilesystemGetExecutablePath
to get the proper path to the apk.
OpenXR basically has a hard requirement that a graphics API is available
before its session can be created. Currently the graphics module isn't
always around when headset initialization takes place. Polling the
graphics availability in update/renderTo has some consequences for calls
made to the headset module in lovr.load or during the first few frames.
So instead we're going to delay headset initialization to a special
function that is called after modules are required. It can also be
called manually if the window creation is delayed.
- Make the renderloop synchronous by hijacking the RAF to run on the
XRSession when active.
- Convert os_web to use emscripten's native HTML5 interface instead
of going through GLFW.
- Stop using preinitialized GL context -- lovrPlatformCreateWindow
now creates the context.
- GLES2/3 emulation is not necessary.
- Remove inline sessions. The VR simulator is used to render to the
Canvas instead. webxr_attach and webxr_detach are used to replace
replace the active headset driver with the webxr driver when an
immersive session starts.
- Add noop desktop_getSkeleton.
- lovr.headset.newModel accepts an optional options table as the
second argument. There is currently a single option named
'animated' that can be used to request an animatable model.
Currently it isn't clear if this should be a hint or not.
- lovr.headset.animate (name pending) can be called with a device
and a model (usually with an animated model from headset.newModel,
but this is not required). The function attempts to animate the
Model to match the pose of the device in an opaque driver-specific
way, and returns whether or not this was successful.
- OpenVR has models for controllers with a system called "components"
that can be used to animate the individual buttons. Now the OpenVR
headset driver implements the 'animate' function to make use of the
controller components, to easily load and render animated controllers.
Add entrypoints, headset backend code, fill in the Activity, and
add various special cases to account for the asynchronous render loop,
lack of sRGB support, and OpenGL state resets.
lovr.log is a new callback that is invoked whenever LÖVR wants to
send the project a message. For example, this could be a performance
warning from the graphics module, an error message from one of the
headset backends, or an API deprecation notice.
The callback's signature is (message, level, tag). The message is a
string containing the message to log, level is a string that is currently
one of "debug", "info", "warn", "error", and tag is an optional string
that is used to indicate the source of the message for grouping purposes.
The default implementation of the callback just prints the message,
but the callback can be overridden to do things like filter messages,
write them to a file, or even render them in VR. Projects can also
invoke the callback directly to log their own messages.
Based on Slack conversation, the following changes:
- lovr.event.quit("restart") no longer supported
- lovr.event.quit no longer takes restart "cookie"
- When lovr.event.restart() called, lovr.quit() is not called, instead lovr.restart() is called
- Value returned from lovr.restart(), when called, becomes the cookie
- lovr.event.quit takes the lovr.event.quit() return code as an argument
lovr.run() is unchanged, it still returns (exit code | "restart", cookie).
- Teach CMake how to compile binary resources to C headers, like xxd.
- Note: tup is already using xxd to do this.
- gitignore binary resource headers to reduce git noise and avoid problematic
interactions between git and build systems.
- One toplevel Tupfile that makes it more clear what happens.
- Add config flags for -Werror, -fsanitize, and separate debug/optimize flags.
- Automatically integrate with libs built by CMake (build folder, rpath, libs folder).
- Disabling modules actually works, only the stuff that's needed is built.
The "mask" example was failing on Oculus Mobile on the line of glsl:
if (lovrViewID == 1) {
because lovrViewID was unsigned and 1 was signed. One way to fix this would be to replace 1 with 1u as that is unsigned, but this would be the wrong fix because lovrViewID is in fact signed on all platforms other than Oculus Mobile. lovrViewID was depending on platform defined to either gl_ViewportIndex (signed), a signed uniform, or gl_ViewID_OVR (unsigned). The solution is to place an explicit cast in the multiview definition of lovrViewID so that it is signed on all platforms.
