Using in a mission script

After reading

LuaImGui Path
For aircraft mods you will want to install the LuaImGui folder in Cockpit/Scripts however you may want
to change the location (for example export or mission lua contexts). To do this you set the global
lua_imgui_path to the path to the LuaImGui folder before calling require on the ImGui.lua.

I've started testing using LuaImGui from a mission script (mission lua state) and can get it to appear but not sure how I would go about handling refreshing. Any thoughts? In the export lua state we can refresh on the next frame, so maybe this won't work from a mission script. Just thought I would give it a try.

Scheduling the update via function using timer.scheduleFunction doesn't feel right and maybe to much overhead.

Awesome work, I knew it was possible since @pschiel has done it but they used a different method if I recall correctly.

Here is their example: https://github.com/pschiel/opsdcs/blob/main/examples/Scripts/Hooks/lua-imgui-example/lua-imgui-example-hook.lua

I believe it uses an export hook and a server in the mission to talk to each other.

for timer.scheduleFunction could you not just have a long schedule interval?

@Rolln-dev if you would be so kind and you find a solution, could you submit a mission example? So that future people who wish to use ImGui in their missions can?

Ok, I will see what I can come up with as for in the mission env. Will take a look at your example.

I have got it to work using the Export env and calling Refresh() in the LuaExportAfterNextFrame function. I've also got it to work using a Hook and calling Refresh() in the onSimulatonFrame user callback.

mission env is not a good place, it should contain only mission related code (that would also run on a server)

better use gui env (hook) which is designed for controlling the client and gui things, and you also have a simulation frame callback there. and pull needed data via dostring_in

[Rolln-dev]

Now that you put it that way, I pretty much agree about the mission env. I haven't fully thought about the end goal but was more seeing what could be done with this. Thanks for the info guys!

I think I already know the answer to this question, but is there anyway that ImGui could ever work in VR?

Unfortunately due to the way the ImGui hook works no I'm afraid. Unless someone figures out a reasonable way to hook the dx11 render calls for VR.
