I'm working on a First Person Shooter style camera setup, and am using action.dx and action.dy - only problem is that the cursor lock / set functions of defos interferes with the build in dx/dy so that the dx/dy movement gets reversed after a mouse cursor moves and then is returned to where it is.

Then do we need to be able to get mouse x/y position and calculate dx/dy ourselves or should I be going about this another way?

Only problem is that the Defold runtime pauses when minimizes

Hi! This is asvegren from the Defold forums.

First of all - massive thanks for this amazing extension.

I have encountered an issue using defos.set_fullscreen(bool_value) and defos.toggle_fullscreen(). I have a gui component that deals with various game settings, including full screen. I noticed that toggling full screen interrups the completion of the rest of the update() cycle in my gui script.

When I click the fullscreen button in my script (which immediately triggers defos.toggle_fullscreen()), the next gui node accessed using gui.get_node() is not found, yielding an error like this:
ERROR:SCRIPT: /HUD/settings/settings.gui_script:19: No such node: scaling_bg

scaling_bg in this example isn't actually deleted however.

I've realised that I don't have any issue if I just move my fullscreen toggle check to the end of the update() cycle (thereby not accessing any more gui nodes), however I thought I would raise this just in case it's important for anyone else.

Hello,

Can I get the mouse movement information by using defos?

Reported by forum user Ross Grams:

I still have a weird issue with maximizing. I think I’ve narrowed it down—if, before toggling maximized or fullscreen from DefOS, I use the windows command (windows-button + up) to maximize the window, then toggle maximize from DefOS, the window vanishes completely. It doesn’t show up in the task bar or the task manager, but it’s still running and sending stuff to the editor console. The only way to stop it is to kill the dmengine.exe process from the task manager (or build from the editor again).

If I do Win+Up to maximize, then toggle fullscreen from DefOS, then toggle maximized or fullscreen back again from DefOS, it crashes.

Useful for editors

Might be better as its own NE

http://zetcode.com/gui/winapi/menus/

Might be an existing cross platform solution which could be wrapped

It would be great if DefOS had a function to get the number of available displays. Also, if possible, to get the name or some kind of identifier for each display.

key-caret can be added to the input but it doesn't actually work (on Windows)

Getting more info

Posting here as a reminder

• set_video_mode - change current video mode to be windowed / fullscreen / window borderless etc.
• restore_video_mode - change back to previously saved video mode
• get_monitors - get list of monitors to be able to set fullscreen on primary or secondary monitors
  * using custom hardware cursors
  * changing window icon
  * setting min / max window sizes? or let user define that?
  * force aspect ratio when window is scaled in window mode? no, let user do this
• enable/disable window decoration
  * add enable versions of existing functions
• gamma ramps?
• get raw key input? possibly problematic because might interfere with engine
  * Change window title
  * lock mouse to window
  * set mouse cursor position
• change resolution of fullscreen window
• get list of supported resolutions of monitor
  * disable locking of mouse cursor at center of screen (what defold does in fullscreen mode atm + it auto disables mouse cursor) possible, but just don't use Defold's built in fullscreen option

I have yet to find the cause

Just check out my project and there is an error. It was working before(3-4 days ago). Looks like there is a problem with latest update/merge.

• Defold Editor 2, MacOs High Sierra.

Looks like commenting out line 85 works fine.

Several changes were made since last release

I am working with publisher and we make Win version of the game.
He told that Alt+f4 and Alt+enter - "must have" functions on windows.

I tried to make this function in lua, but in some popups I block message passing

function on_input() 
...
return true
end

What do you think, should I add this functions to defos (Win only)?
Or it should be an optional for a developer? But how this options should work then? Do you have any ideas?

defos.move_mouse_to(x,y)

Move mouse to x,y coordinates of the game window client area.

win/mac/linux only

Anything which should be done before publishing a 2.0 release?

It's too hard to scale / move window otherwise

I need to lock minimum aspect ration as of the window (on windows) 4:3 and maximus as 16:9.
Do somebody have some ideas how I can do this using DefOs?

From a tester

First off, it was set to fullscreen but in a windowed mode about 1/4 my laptop's resolution. I unchecked and checked "Fullscreen", and the game changed to fullscreen. After restarting the game, it was marked as fullscreen again, but still in a much smaller window, same as before.

This is all on Xubuntu 16.04, so I'll give a try on Xubuntu 18.04 when I get the chance after I finish work later tonight.

I would like to be able to get a list of all the resolutions that a display supports. Hopefully this would support multiple monitors, you would pass in an index for which display you want to check.

1. set new cursor position with move_cursor_to
2. initiate any input action - action.x\action.y are correct, but action.screen_x\screen_y have old values

There's quite a few commits since the last release. Is it possible to do a release of the new features and fixes or are they considered experimental? Or should I simply depend on master and expect that new commits will ensure backwards compatibility with the API?

Cool thing!!

http://www.glfw.org/GLFWReference27.pdf
http://www.glfw.org/GLFWUsersGuide27.pdf

glfw.h.zip

If we add this header file to the project then we can call the GLFW 2.7 functions directly. A bunch of them are useful and are already cross platform.

If we can include the built in glfw.h I think that should be the way to do it though so I'm asking what the path to it is in the forums. It also might matter if Defold team has made changes to the GLFW 2.7 version I don't remember if they said they did or not, but we can still find with experimentation if features don't work as expected.

I accidentally dragged my game.project file into another folder and everything exploded

On macos window position sets from left down corner.
for example

 	defos.set_window_size(-1,-1,800,600)

As I know on windows position starts from top-left corner? Am I right?

I think we should resolve this issue.
We can identify what exactly screen point point we should consider like a 0,0?
And then implement the same behavior for all platforms.

Native extensions now supports Linux so support for it needs to be added.

I'd guess Linux native extensions will come next release, can make sure it has feature parity without issues, and then publish first versioned release. Then encourage people to use versioned releases in important projects. Though we probably won't make major changes that would break existing projects it's better to give people sense of security that using the lib won't break their project if we publish updates.

Should be this with SW_SHOWMAXIMIZED I think
https://msdn.microsoft.com/en-us/library/windows/desktop/ms633548(v=vs.85).aspx

Could also add functions for minimizing, making window get focus, making taskbar blink / light up,

It should not be allowed to change cursor position when window is not in focus

Fullscreen toggle for example

As I think would be better to have one simple method for every platform set_cursor(nil or CONSTANT or path) where user can set path to the image .

I think those constructions are difficult:

• On HTML5, an URL to an image (data URLs work as well)
• On Windows, a path to an .ani or .cur file on the file system.
• On macOS, a table of the form

`

if system_name == "Windows" then
	for i, v in ipairs({ "cursor_01.ani", "cursor_02.ani" }) do
		-- load source file and write them to save folder, so that we can access them with fullpath
		local cursor_resource = resource.load("/resources/"..v)
		local raw_bytes = buffer.get_bytes(cursor_resource, hash("data"))

		local cursor_path = sys.get_save_file(appname, v)
		local f = io.open(cursor_path, "wb")
		f:write(raw_bytes)
		f:flush()
		f:close()

		print(cursor_path)
		table.insert(self.cursors, cursor_path)
	end
end

if system_name == "Darwin" then
	table.insert(self.cursors, {
		image = resource.load("/resources/cursor_mac.tiff"),
		hot_spot_x = 18,
		hot_spot_y = 2,
	})
end

if system_name == "HTML5" then
	table.insert(self.cursors, cursor_url)
end`

Developer can include cursor file "as is" into the bundle using hidden parameter: bundle_resources (I made it with icons). https://www.defold.com/manuals/project-settings/#_project

Thanks to @dapecthu I made:
defos.get_bundle_root() - method that returns path to bundle,
defos.PATH_SEP - path separator depends of platform.
Those methods can help with this remaking.

I can make it after merging my current set_icon pull-request. What do you think about it?

After calling defos.set_cursor_locked(true) on macOS, Defold doesn’t receive dx/dy events anymore. I suspect it’s because Defold’s input code diffs mouse positions instead of using NSEvent.deltaX and NSEvent.deltaY.

I tried locking the cursor both by calling CGAssociateMouseAndMouseCursorPosition(false) and by repeatedly setting the mouse position to the same point each frame with CGWarpMouseCursorPosition() and I got the same results.

I propose we change the following:

defos.disable_mouse_cursor()
defos.enable_mouse_cursor()
defos.toggle_maximize()
defos.is_maximized()
defos.toggle_fullscreen()
defos.is_fullscreen()

To the following:

defos.set_mouse_cursor_hidden(true)
defos.set_mouse_cursor_hidden(false)
defos.is_mouse_cursor_hidden()
defos.set_maximized(true)
defos.set_maximized(false)
defos.is_maximized()
defos.set_fullscreen(true)
defos.set_fullscreen(false)
defos.is_fullscreen()

This has the benefit of not having to know what state fullscreen is in before you toggle. You can just say set_fullscreen(true) to make sure you're in full screen, and if you were already full screen, then nothing happens. Toggle could be implemented by the user as defos.set_fullscreen(not defos.is_fullscreen()).

What do you think?

This is obviously a breaking change, but better make it now before 1.0.

defos.set_window_size is based on window size and not client area size. We either need another function or to modify this so it's based on resizing the client area. This is important for pixel art games especially so people can easily set 2x, 4x window sizes of default res for even pixel scaling.

https://forum.defold.com/t/android-builds-with-native-extensions-fail-def-3026/14326/10

The actual compile error was from the fact that defos doesn’t support android yet, so you get a linker error. Perhaps @pkeod could add a null-implementation for it? E.g. adding the C++ symbols, but not registering a defos Lua module, so the user can check for it?

defos.get_cursor_pos() -- screen
defos.get_cursor_pos_view() -- view

Would return the cursor position x,y relative to the game's view. Then we can get/set cursor position between frames while calculating dx/dy ourselves.

Getting lots of reports from Linux users that toggling fullscreen like we do on main.script init does not work, only when they go to options screen can they toggle fullscreen. Not sure of a solution other than to toggle fullscreen after a moment on Linux. Maybe an error is happening when toggling as soon as a project inits on Linux?

Work on Mac/Win though.

Might be easy with buffers

I use defos on a day to day basis to change resolution on the fly and test against the most common mobile ones and it is great!
It would be also great to have an option to always keep the window on top of the others. I use hot reload a lot and that would help not switch windows constantly.

Is there any way to spawn multiple windows at the same time?

If it is not, that would be an amazing feature :)

repro on windows, i will try to fix this issue later,

Functions to see what's in clipboard, take what's in clipboard, put text into clipboard.
