So far we left most temporary files lying around, so this attempts to
fix that.
I added a helper method to DirAccess to factor out the boilerplate of
creating a DirAccess, checking if the file exists, remove it or print
an error on failure.
In the Visual Script editor, the override icon is not very clear what it's intended purpose is for. Currently, its tooltip just says: "Function:" which is the same tooltip as the "add new function" icon.
To resolve this issue, this PR adds descriptive tooltips to the following icons in the Visual Script editor:
-Override Function
-Add Function
-Add Variable
-Add Signal
This might be especially usefull since godot script doesn't support ** or ^ as operators, so beginners might search for the exponential function, when what they really need is the pow function.
This is exactly what happened to me and since I couldn't find helpfull information in the documentation I had to look it up online, where I found the answer on a helpfull [reddit thread](https://www.reddit.com/r/godot/comments/3mvwz0/how_do_i_do_exponents_in_godot/).
@akien-mga told me how to reference methods here:
godotengine#30909
These silently fail, so they should be removed. I accidentally added most of these last year, trying to make everything else consistent with Quat, sorry!
Also, a few tiny nitpicking changes are included, like whitespace and misspellings.
Mono's MSBuild and System/VisualStudio's MSBuild expect a different format for surrounding property values with quotes on the command line.
xbuild does not seem to support semicolons in property values from the command line: https://xamarin.github.io/bugzilla-archives/16/16465/bug.html
It's a good time to just remove xbuild support entirely.
Previously, when running the project manager, we would try to load the API assemblies from the project and fail because we were not editing any project. This would make us try to copy the prebuilt API assemblies to the project. Since there is no project, it would try to copy them to the executable location. This would fail if Godot doesn't have permissions to write to that location.
This commit fixes that by instead trying to load the prebuilt API assemblies in the first place, if running the project manager.
This was a regression in 3.1 and later from the new inspector, where
PROPERTY_HINT_SPRITE_FRAME was not fully re-implemented. It's meant to
be a normal PROPERTY_HINT_RANGE which also automatically increments its
value when keyed in the animation player.
To avoid code duplication, I made the frames properties use the actual
PROPERTY_HINT_RANGE and introduced a PROPERTY_USAGE_KEYING_INCREMENTS
usage flag instead.
