Add official Raspberry Pi support

[heniotierra]

I know the Raspberry Pi and Raspberry Pi 2 are not officially supported, and that there is a working fork out there, but it has got some issues which make it close to worthless. However, I think that some of those problems might be easy to address.

For example, one of the big issues is that the mouse cursor is always under the interface objects, but I think that if one can make the mouse cursor be drawn by Godot's GUI in a similar way as the other interface objects, that would be enough for solving the problem. I guess that would be pretty easy to implement.

I don't know anything C++, only C (and also some OO languages), otherwise I could do that myself. But then, if someone can at least give me directions like where to begin to look at the source files to use the stuff to do this, I'd be glad, and very willing to try.

Theme already has a cursor override doesn't it?

What do you mean? Raspberry Pi is just a computer without OS. You can install Linux or Android on the device and play your Godot project (Linux binary or APK respectively).

If there's a basic api to access the hardware (screen, input, sound,
filesystem), a port could just "boot" a godot game directly, like on old
consoles. It'd probably run faster, and also a pain in the ass to make :p
Games might need to be more careful about memory if there's no OS providing
virtual memory too (like on old consoles). Sounds like fun.

One of the issues is that the Raspberry Pi handles 3D stuff by drawing directly on the hardware (screen), not through X, while the mouse IS drawn thourgh X, making the mouse cursor not to be visible, for the interface (drawn with hardware acceleration?) is on top of it.

This specific issue is described on the working port fork: x1212#1

Did you try the "custom_mouse_cursor" option on project settings?

I did not, nor am I able to atm, but will do tomorrow. :)

Since I merged the latest changes into my fork yesterday it now supports the "custom_mouse_cursor" option, but that seems to only work in a running game, not in editor or when selecting a project from the list.
I did find a place in main.cpp, where I could try to add that option on startup, but the problem is, I didn't find any way to provide a path to for example /home/USERNAME/.godot/cursor.png (or /.godot/cursor.png), since that will be changed to res:///home/USERNAME/.godot/cursor.png (or res:///.godot/cursor.png) by the resource loader and so on. That means it would need one cursor.png for every possible location res:// can point to.

Btw. if there are any plans for providing official support for the Raspberry Pi, the next few days would be a good time to have a look at the necessary changes (currently they can be found on the raspberry branch https://github.com/x1212/godot/tree/raspberry) since I should have enough spare time to help until the middle of next week.

you should be able to run a script with the keyword to change default cursor inside editor...

[MarianoGnu]

you should add the cursor to the editor icons

1. add cursor.png to Godot\tools\editor\icons
2. run make_icons.py
3. get the texture to set the custom cursor using this line:
   Ref cursor = get_icon("Cursor","EditorIcons");

[x1212]

Thanks, I got the cursor to work in the project manager that way, for some reason it didn't work for the editor, but in the editor scripts can be used, so that shouldn't be such a big problem anymore (but I'll try to fix it anyway).

@x1212 "I did find a place in main.cpp, where I could try to add that option on startup"
probably this line you mention runs only when the project manager is launching
