Compilation and usage for LOVE2D #20
Comments

From a sibling folder to the repo folder but if you use https://github.com/sonoro1234/anima it will build GLFW, SDL and LuaJIT-ImGui for you |
|
Okay, honestly, I rarely collect anything because it's hard. What's an anima? I don't know what to do with it, so I need to clarify it for SDL2. If it's not difficult, how do you build it in more detail? |
|
https://github.com/sonoro1234/anima is my repo for working with opengl. |
|
Okay, thanks, maybe I'll figure it out later, but I couldn't. Here's the conclusion. Maybe I should specify luajit in DLUAJIT_BIN, I did it in an empty folder. |
|
When you clone the repo you should do it recursively to also clone the git submodules. For LUAJIT_BIN use ""/home/sergey/anima" for example |
|
Okay, I did the first item, some files were not found there, but it went well. And "make install" at the end gave me errors. |
|
implot source was not up to date. |
|
Now it was 96% I decided to restart, but it didn't help. |
|
Yes, it did help. google |
|
Ugh, it helped, the assembly was successful. I take it now everything has to be searched in the directory I indicated? |
Yes In the anima\examples\LuaJIT-ImGui\examples folder you will find the LuaJIT examples, you should run them from a terminal (or your prefered code editor) |
|
The thing is that I'm using the LOVE2D framework and I need to run it, I thought it would be at the end of the .so dynamic library and I could connect them. |
|
It is not a LOVE2D module but just a LuaJIT module. Someone has to port it to LOVE2D. Perhaps https://github.com/Jarodwr/love-imgui-wip but I have not tried it and it seems to need more work for linux building. without using LuaJIT-imgui you have https://github.com/YoungNeer/lovely-imgui but I guess it will be not up to date with latest imgui |
|
Just LOVE2D is assembled with LuaJIT |
|
I was able to run your implementation in LOVE2D by copying the libraries to LOVE2D. And I put https://github.com/Jarodwr/love-imgui-wip, but alas, it didn't work. Thank you for trying to help me, I think you can close the issue. Next, if the author builds for linux, it'll be great. |
|
Decided to show you what I've achieved, maybe you know how to fix it. I combined sdl.lua and its init.lua, and the result worked, except that the window looks weird, but it works and moves. |
Without a more detailed description of what you have done I wont be able to help you. Besides that: Actually it was quite simple to run imgui in LOVE2D without any modification at all: put imgui folder inside love/lua main.lua local imgui = require "imgui.sdl"
local ffi = require"ffi"
ffi.cdef[[
typedef struct SDL_Window SDL_Window;
SDL_Window *SDL_GL_GetCurrentWindow(void);
void* SDL_GL_GetCurrentContext(void);
]]
local sdl = jit.os == "Windows" and ffi.load("SDL2") or ffi.C
local instance
love.load = function(table)
local sdlwindow = sdl.SDL_GL_GetCurrentWindow()
local openglctx = sdl.SDL_GL_GetCurrentContext()
instance = imgui.Imgui_Impl_SDL_opengl3()
instance:Init(sdlwindow, openglctx)
end
love.draw = function()
instance:NewFrame()
if imgui.Button("Hello") then print("Hello") end
instance:Render()
endTell me if this is working for you so I will make imgui.love2d.lua in order to avoid sdl stuff on main.lua @ocornut Could you please add LuaJIT-imgui to the list of LÖVE+LUA bindings? |
|
Probably should have said that I got it then, I just imgui put it in love/lua, but with a direct request SDL I did not. At https://github.com/Jarodwr/love-imgui-wip the renderer is not via SDL but via LOVE2D, so imgui takes a table of what to draw but with LOVE2D renderer. I'll try yours later. |
|
Everything is working fine, thank you for taking the initiative and even creating an offer for the developers to make a bridge. Even though it's a trifle, so far all I can do is to point you in the information to my application as contributing to its development, because I was even thinking about switching to some other language. local imgui = require "imgui.sdl"
local ffi = require"ffi"
ffi.cdef[[
typedef struct SDL_Window SDL_Window;
SDL_Window *SDL_GL_GetCurrentWindow(void);
void* SDL_GL_GetCurrentContext(void);
]]
local sdl = jit.os == "Windows" and ffi.load("SDL2") or ffi.C
local instance
love.load = function(table)
local sdlwindow = sdl.SDL_GL_GetCurrentWindow()
local openglctx = sdl.SDL_GL_GetCurrentContext()
instance = imgui.Imgui_Impl_SDL_opengl3()
instance:Init(sdlwindow, openglctx)
end
love.draw = function()
instance:NewFrame()
if imgui.Button("Hello") then print("Hello") end
instance:Render()
end
love.quit = function()
instance:destroy()
end
love.textinput = function(text)
instance:__textInput(text)
endsdl.lua function Imgui_Impl_SDL_opengl3:__textInput(text)
lib.ImGuiIO_AddInputCharactersUTF8(lib.igGetIO(),text)
end |
|
Yes, sdl events were missing now there is imgui.love module and a love example. |
|
|
I think you are mixing the imgui lua modules from master branch with the module compiled from docking_inter branch (this is the module included in anima). |
|
So, I have to rebuild? I downloaded from github, copied from lua's folder, that's all. |
|
Or dont rebuild but take the lua modules from docking_inter branch (the one you get when you clone anima) |
|
Everything's okay, and it's working. |
|
I have also improved building LuaJIT-ImGui alone (without anima) with dependencies in the readme and a new linux script. |
|
Okay, I'll check. |
|
Added use_imgui_viewport, will only work in docking-inter branch. |
|
First of all: This is not a general imgui.love issue, (Compilation and usage for LOVE2D) you should open a new issue for things happening in the future. You should provide context information about the issue: version, commit, branch ... This error you are posting is not according to current imgui.sdl docking_inter branch https://github.com/sonoro1234/LuaJIT-ImGui/blob/docking_inter/lua/imgui/sdl.lua#L1342 |
|
please open new issue with this. Should be called undefined symbol |
Can you please give instructions on how to compile for linux?
